    Beschreibung: Rhizome usually short-creeping with closely-placed fronds, less often widecreeping or somewhat erect, the young parts covered with thick septate hairs (except Mohria, not Malaysian), structure dorsiventral or radial, vascular strand in Malaysian genera a protostele (medullated in Schizaea). Fronds of very varied structure, their branching showing varying gradations from dichotomous to pinnate; veins usually free; sporangia borne on specialized segments of the fronds (sorophores) except in the non-Malaysian Mohria. Sorophores at the ends of veins of fertile leaflets (Lygodium), or in small pinnate groups at the apex of a frond or of its branches (Schizaea), or confined to special branches of the frond (Anemia, not Malaysian). Sporangia arising marginally but becoming superficial due to subsequent extra-marginal growths, large, borne on short massive stalks or sessile, with an almost apical annulus of a single row of elongate thickened cells, dehiscing on a line from annulus to base. Spores trilete or monolete (Schizaea only), without perispore, the surface usually sculptured. Gametophytes filamentous in Schizaea, thalloid in other genera, symmetrical or not. Distribution. The Malaysian genera Schizaea and Lygodium are pantropic with a few outlying species of both in temperate regions (U.S.A., S. Africa, Chile, Japan, and New Zealand). Anemia has its main distribution in tropical America, with a few species in Africa and one in southern India. Mohria is confined to southern and eastern Africa and the Mascarene Islands.

    Beschreibung: Herbaceous, perennial, submerged aquatics or marsh plants, usually with annual grass-like leaves arising in a tuft from a lobed, flattened, corm-like stock. Stock divided into stem and rhizophore, 2—4-lobed, with black dichotomous roots arising from the furrows between two lobes. Roots monarch, with the stele attached to one side of a central cavity, vascular system protostelic, 2—4- lobed at base. Leaves distichous, crowded, with overlapping bases, terete or flattened above, with a broad spoon-like base. Blades with a simple trace and median, unbranched vein, accessory peripheral strands often present; mesophyll chambered with four longitudinal cavities divided by transverse diaphragms, Which give the leaf a muriform appearance when seen in transmitted light. Stomata present on one or both surfaces in some species and absent in others. Leaf-bases usually membranaceous and hyaline but in some species persistent as hard, brown, 2-lobed, horny structures. Ligule present near the base of the leaf above the sporangium, arising from a cavity called the ligular pit, cordate-triangular or subulate, 2—15 mm long, without chlorophyll or cuticle, secreting mucilage at least when young. All leaves potentially sporophyll with a sporangium seated in a pit (fovea) on the adaxial surface below the ligule. Megasporophylls normally arising below the microsporophylls; opening of fovea often wholly or partly covered by a membrane (velum) extending downwards from the apex. Sporangia large, 4—7 mm long, oblong, thin-walled (walls with 3—4 layers of cells), subdivided irregularly and incompletely by oblique sterile plates (trabeculae); of two kinds, megasporangia and microsporangia, sessile and broadly adnate. Sporangia with both megaspores and microspores have been reported and the megaspores often vary considerably in size. Megasporangium containing 50—300 trilete spores, 250—900 μ in diam., white, grey or black, smooth or with warts, spines, or ridges. Microspores monolete, elliptic, 20-45 μ long, smooth or papillose, 150.000— 1.000.000 in each sporangium. Annulus wanting, spores released by the decay of sporangial walls. Some species may be aposporous with young plants taking the place of the developing sporangia. Gametophytes dioecious. Female prothallus green, development starting within and the prothallus remaining attached to the wall of the megaspore. Archegonia one or more up to 30, deeply sunken. Rhizoids present, projecting beyond the spore wall. Male gametophyte arising within the microspore, consisting of only a single prothallial cell and an antheridium, with 4 peripheral cells and 4 central cells, each giving rise to a single antherozoid with 15 flagellae. Distribution. About 75 spp., in all parts of the world except the Pacific Islands (present in Tasmania and New Zealand), but mainly temperate, scarce in Asia, in Malaysia 3 spp., one in the hills and two

    Beschreibung: The work of preparation of a new survey of all the Pteridophytes of Malaysia will occupy a considerable period. It is proposed to publish this work in parts, as studies of particular families or genera are completed, but it is impossible to plan in advance the precise sequence of these studies. It is anticipated that the new information to be recorded, and new ideas based upon it, will throw a good deal of new light on the delimitation of genera, and upon the inter-relationships of genera, especially among the ferns, which are by far the largest of the major groups concerned. Therefore one cannot now predict what final scheme of classification will emerge. But it is necessary to have some sort of conspectus at the start, as a preliminary survey of the ground to be covered, and as a guide for those who wish to consult the parts of the work as they appear. I have therefore drawn up a list of the major groups, with the genera in each, and also a series of keys to the genera of ferns. The nomenclature of the major groups, the generic concepts, and the keys, must all be regarded as tentative.

    Beschreibung: Two small but interesting collections of octocorals from the northeastern coast of South America have recently come into my hands through the U.S. Fish and Wildlife Service, one of them from a survey conducted by the Government of Surinam, the other from exploratory work of the U.S. Fish and Wildlife Service. The first was obtained off the coast of Surinam by Mr. J. C. HIGMAN, U.S. Fish and Wildlife Service observer aboard the motor vessel “Coquette” during the course of exploratory shrimp investigations. The second was obtained between Trinidad and the Amazon River, Brazil, through the efforts of Dr. GILES W. MEAD during the course of cruise 47 of the exploratory vessel “Oregon.” Because there is so little information available dealing with the fauna of the northeastern coast of South America, it seems desirable to make known the records of Octocorallia taken by the “Coquette” and the “Oregon” along this extensive and little known coast, together with a list of the species already reported in the literature. The four new species contained in the present material are described and figured in full, and figures of the spicules of the known species are given in support of the identifications set forth.

    Beschreibung: In the second half of the nineteenth century an important contribution to our knowledge of the fauna of the Netherlands Antilles, and especially of St. Martin, was made by the medical officer of that island, H. E. VAN RIJGERSMA, whose name, however, has remained almost unknown to Dutch biologists. By assembling important zoological collections VAN RIJGERSMA enabled specialists to study the fauna of St. Martin and the neighbouring islands; as a result, this fauna was for a long time better known than that of many other West Indian islands. From information kindly placed at my disposal by the Rijksarchief (Netherlands State Archives) and the Record Office of the Ministerie van Zaken Overzee (Netherlands Ministry of Affairs Overseas) it appears that HENDRIK ELING (or ELINGSZ.) VAN RIJGERSMA was born in 1834 or at the beginning of 1835, and was very probably of Frisian origin. It is not known where he studied; but he practised on the island of Marken, in the Netherlands, as doctor, surgeon and obstetrician, until the year 1863. By Royal Decree No. 60, dated 26 June 1863, VAN RIJGERSMA was appointed Government Physician on the Dutch West Indian island of St. Martin, where he went in the autumn of 1863 with his wife and two children. He filled this post on St. Martin until his death on 4 March 1877, only once returning on furlough to the Netherlands, from Spring 1873 till March 1874. He was married to MARIA HENRIETTA GRÄFING, probably from Amsterdam. At his death he left seven children. His widow continued to live on St. Martin until 1893, when she went back to the Netherlands with five of her children.

    Beschreibung: Capítulo 1. Introducción Se han ejecutado investigaciones geomorfológicas en la parte meridional de la Cordillera Cantábrica (dib. 1), en el terreno drenado por el tramo superior del Río Pisuerga, por el Río Camesa, afluente del mismo, y por el Río Rubagón, afluente del Río Camesa. Se encuentra la región investigada en la zona donde se halla el límite entre las rocas Paleozoicas y las Mesozoicas de la Cordillera (mapa 2). Más hacia el Sureste, desde Cervera de Pisuerga se extiende una zona de rocas Mesozoicas plegadas, llamada por Ciry (1939) : ”Le Pays Plissé” (mapa 1). Es una zona de relieve intermedio, ni tan alto como la Cordillera Cantábrica, ni tan llano como la Meseta, que se encuentra más hacia el Sur de dicha zona. Existe una gran diferencia geomorfológica entre las vertientes septentrional y meridional de la Cordillera Cantábrica, como resultado de la situación alta de la Meseta. Los ríos de la vertiente norte en una recorrida de cerca de 50 kilómetros llegan el Mar Cantábrico y así pasan un desnivel de más de 1300 metros; los ríos de la vertiente sur se dirigen a la Meseta que aquí, en su parte norte, tiene una altura de 1000 metros. Es decir, poco más o menos, en la misma recorrida, los ríos pasan un desnivel que es 1000 metros menor que el de los ríos de la vertiente norte. Como resultado, los valles de la parte norte están profundamente agrietados, con considerables pendientes, caracterizándose la parte sur por amplios valles, con suaves pendientes; es la misma altura topográfica, pero el fondo de los valles se encuentra a unos 1000 metros más alto que en la parte norte (dib. 2). Menos pronunciado, pero también claramente visible es el contraste en relieve con la región de la cuenca del Río Ebro, que limita la cuenca del Camesa en el norte y noreste. El clima de la región considerada forma la transición entre el clima de tipo atlántico de la costa cantábrica, y el clima semi-árido del interior de la Meseta. En dib. 3, el clima de Cervera de Pisuerga y de Reinosa está ilustrado gráficamente (según F. Hernández Pacheco, 1944). La cartografía de las unidades morfológicas ha sido realizada a base del Mapa de España, escala 1:50.000. Las hojas utilizadas se presentan en dib. 1. La naturaleza litológica de los cantos de terrazas fluviales fué determinada en los cantos mayores de 2 cms de diámetro; el índice de desgaste fué determinado en los cantos mayores de 4 cms de diámetro. Es para eliminar la influencia de las pudingas triásicas que no hemos considerado los menores de 4 cms (veáse Capítulo 3). Se calcula el desgaste mediante la fórmula de Cailleux: Ie = 2re . 1000/L La granulometría de arenas y arcillos fué realizada por el método de “criba-pipeta”; los resultados son representados por curvas logarítmicocumulativas. El desgaste de los granos de cuarzo se obtuvo de la misma manera que el desgaste de los cantos rodados; el examen de las muestras se ejecutó bajo el micróscopo binocular. La determinación de los minerales densos se hizo de la manera acostumbrada. Capítulo 2: Geología Las más importantes características geológicas de la región investigada se describen en este capítulo, según las investigaciones de los autores Karrenberg (1934), Ciry (1939), Quiring (1939), De Sitter (1955 y 1957) y Kanis (1956). Rocas cristalinas apenas si se encuentran. El Devónico se halla en la parte NO de la cuenca del Río Pisuerga y se compone de areniscas cuarcitosas y cuarcita, alternando con calizas. En el Carbonífero tres unidades litológicas pueden distinguirse : calizas masivas y cristalinas, conglomerados de gran espesor (el llamado conglomerado Curavacas) y una alternación de pizarras, areniscas y conglomerados, a veces también de calizas. Se compone el Permo-Triásico de conglomerados más finos y claramente distintos de los Carboníferos, y de areniscas gruesas, de color rojizo. El Keuper principalmente se compone de margas y arcillas; el Jurásico de calizas bien estratificadas y de margas. El Wealden tiene una litología muy característica, componiéndose de conglomerados finos de cuarzo y cuarcitas, calizas lacustrinas, y areniscas bastante gruesas. Está mal cementado, de modo que por la alteración se forman fácilmente arenas y cascajos. El Cretaceico superior sólo se encuentra en unos lugares, como al Sur de Cervera de Pisuerga. Se compone, generalmente, de calizas. Las estructuras de la fase Sudética (llamada la fase Curavacas por De Sitter) tienen una dirección E—O, las de la fase Asturiana (fase Peña Cilda) una dirección NNO—SSE. Las deformaciones Terciarias son visibles en la región del Valdecebollas, pero quedan sin datar. Capítulo 3: Alteración, denudación y formación de pendientes en diversos tipos de rocas La Caliza de Montaña forma el relieve en toda la Sierra del Brezo. En ningún lugar hemos hallado sedimentos con derrubios derivados de esta Caliza, salvo en una brecha situada al pie de su vertiente meridional. Las pendientes de denudación (“Richter-slopes”, cotéjese Bakker, 1952) de esta Caliza son muy características, con ángulos de inclinación de 25—30° (dib. 5). Otras calizas Paleozoicas, por encontrarse más aisladas, tienen menos importancia en relación con la formación o deformación de pendientes. En el conglomerado Curavacas, que se encuentra en una región extendida, las pendientes de denudación pueden tener los ángulos más variados, pero las transiciones son siempre suaves. Los conglomerados Triásicos son más finos y más compactos, de suerte que reaccionan de manera completamente diferente en la eflorescencia. En el conglomerado Curavacas la “matriz” de los cantos se pulveriza, de manera que los cantos individuales son librados, los conglomerados Triásicos, al contrario, reaccionan a lo largo de diaclasas, de tal manera que se forman cantos compuestos de conglomerado Triásico. Las pendientes de denudación en las rocas Triásicas son de perfil sencillo, rectilinear o suavemente curvado (dib. 5). Las esquistas Paleozoicas no tienen gran resistencia contra la alteración; rápidamente se descomponen en arcillas, pero por la fuerte erosión generalmente desaparece la arcilla formada, dejando la roca expuesta a nueva alteración. Por eso, la mayoría de las pendientes de esquistas es muy compleja, no existe un tipo general. Las areniscas forman en muchos sitios interrupciones de las pendientes, a causa de su mayor resistencia. La composición de los minerales densos de unos productos de alteración se presenta en dib. 7. Capítulo 4: Fenómenos glaciarios y periglaciarios Los fenómenos glaciarios de la región investigada han sido estudiados ampliamente por F. Hernández Pacheco (1944), junto con los del valle de Campo de Suso. Por eso, no nos hemos ocupado intensivamente de tales fenómenos. Fenómenos periglaciarios se observan en toda la región. Hay bloques de dimensiones impresionantes (dib. 10), que se han deslizado suavemente hacia abajo sobre un suelo permanentemente helado, bloques que se encuentran, sobre todo, en las regiones más elevadas. Luego hay “dellen”, valles secos de perfil transversal de forma concava (Schmitthenner, 1925), entre los cuales pueden distinguirse dos tipos: el tipo “hamaca” y el tipo de “suelo llano” (dibs 11 y 12, respectivamente). El suelo de estos últimos es más llano que el de los primeros, pero también concavo. Finalmente, la soliflucción ha sido muy activa en toda la comarca. Es difícil observar, dónde sólo ha sido activa bajo el clima periglaciario, y dónde todavía sigue activa como “soil creep”, el que hemos encontrado en muchos sitios. Capítulo 5: Descripción de las terrazas del Río Pisuerga El Río Pisuerga se caracteriza por la presencia de numerosos restos de terrazas fluviales. Pueden agruparse en los niveles siguientes: La terraza HP altura relativa 120—150 m „ „ LH „ „ 80-100 „ „ „ HM „ „ 50—55 „ „ „ MM „ „ cerca de 40 „ „ „ LM „ „ 20—30 „ „ „ HL „ „ 5—10 „ „ „ Baja „ „ hasta 5 „ Dibujo 13 representa un perfil longitudinal del Río Pisuerga, con la proyección de las terrazas. El número de cada una de las partes individuales corresponde con el número de la descripción en Capítulo 5. Terraza HP. Las partes de Herreruela (1) y San Felices (2) son casi libres de sedimentos. Al NO del Pantano de Vañes se encuentran las partes de Polentinos (3) que están cubiertas de un mezclado de cantos cuarcitosos, Triásicos y areniscos. Al NO de Cervera de Pisuerga se encuentra la parte de Cervera (5) (dibs. 14 y 15), formada de una llanura alta, de dimensiones impresionantes, cubierta de una capa de gravas fluviales, principalmente cuarcitosas, de un espesor de 12—14 metros. Al otro lado del valle del Pisuerga se halla la parte de Rabanal (6) que resulta la continuación de la parte de la Cervera. Al Sur del valle del Río Rivera se hallan las partes de Vado y de Dehesa (7) (dib. 16), que claramente son del mismo nivel. La altura relativa es la misma que la de la parte de Cervera, igualmente existe la cobertura sedimentaria de cantos cuarcitosos, encontrándose en ella cantos del conglomerado Triásico en una proporción de menos de 1 %. Es importante esta presencia, porque indica que anteriormente el llamado Pisuerga Alto (el río tal como existía en la época de sedimentación de la terraza HP) desde Cervera continuaba en dirección sur, pasando por el Puerto del Brezo, que es la depresión marcada entre las rocas Mesozoicas del Mariserrana, y las calizas Carboníferas de la Sierra del Brezo. Más hacia el Sur se ensancha la terraza y queda menos claramente visible. Esta parte ha sido estudiada por Mabesoone (1959). La terraza LH sólo se halla cerca de Cervera (4), a una altura relativa de 80—100 metros; se caracteriza por la ausencia de cantos, estando la superficie formada en un sedimento arenisco que también se encuentra bajo la terraza HP. Parece que este sedimento es de más edad que la terraza HP. Cerca de Ligüerzana, se halla una parte de la terraza LH a una altura de cerca de 80 metros sobre el nivel del río; aquí los cantos cuarcitosos tienen un espesor de cerca de 2 metros. Al Sureste de Salinas, se hallan restos de la terraza LH en las partes de Barrio (13) y de Humín (15). En las dos, los cantos son escasos; sin embargo, la cobertura sedimentaria alcanza un espesor de 3—4 metros. Las terrazas intermedias. El nivel HM se encuentra en las partes de San Mames (14) y de Frontada (16). Hay una cobertura de sedimentos fluviales, de un espesor de 2 a 3 metros. El nivel MM se halla en las partes de Barcenilla (11) y Salinas (12). Aquí también el sedimento tiene un espesor de 2—3 metros. El nivel MM se ha conservado en sitios aislados (8, 9, 17). La terraza Baja. El nivel HL sólo se encuentra al NE de Aguilar; la terraza propiamente dicha se presenta casi en todas las partes del tramo del Río Pisuerga, salvo en el tramo superior (cotéjese mapa 1). Capítulo 6: Petrografía sedimentaria de las terrazas del Rio Pisuerga El estudio de los sedimentos fluviales conduce a las conclusiones siguientes. Los cantos de todas las terrazas de cualquier altura relativa se componen en su mayoría de cuarcitas, procedentes del conglomerado Curavacas. Los cantos de la terraza HP se caracterizan por índices de desgaste bastante altos, que excluyen una influencia de clima periglaciario en la época del Pisuerga Alto. Los cantos de las terrazas intermedias y bajas están mucho menos rodados, lo que indica la influencia del clima periglaciario en aquellos tiempos. El análisis de los sedimentos nos demuestra que el sedimento ha sido depositado bajo condiciones de “braiding rivers”, es decir que hubo más derrubios de los que el río pudo transportar. Los depósitos de las terrazas intermedias también han sido sedimentados bajo importantes alternaciones en el régimen fluvial. Como son menos espesos y tampoco tienen la gran distribución horizontal de los sedimentos de HP, las épocas en las cuales fueron depositados habrán sido bastante más breves. Los granos de cuarzo de 500—1050 µ de diámetro son generalmente angulares, como se ve del dib. 27. Unos porcientos tienen altos índices de desgaste, lo que puede indicar que localmente ha habido influencia eólica. Los análisis de los minerales densos se presentan en el cuadro 10 y en el dib. 28, en los cuales se observa una predominancia de los minerales circón, turmalina y rútilo. La estaurolita procede del Triásico, pero esto no quiere decir que todo el Triásico se caracterice por la presencia de estaurolita. De las observaciones hechas se concluye que en la época del Pisuerga Alto, el río tenía dos importantes arterias superiores, una de ellas procedente de la zona del conglomerado Curavacas, bajando la otra del escarpamiento del Triásico. Desde Cervera continuaba al Sur, pasando por el Puerto del Brezo. De la continuación de la terraza HP con respecto a la raña de Guardo, se deduce que la terraza es más reciente, es decir que probablemente es de edad Villafranquiense superior. Después, el Pisuerga Alto fué capturado por un afluente del Camesa Alto, que en un tramo subsecuente en rocas de poca resistencia podía agrietarse rápidamente por erosión regresiva. Después de la captura, el Río Pisuerga se desvió desde Cervera hacia el Este; el nuevo suelo del valle, tras una fase de incisión, formó la terraza LH. Las terrazas intermedias (HM, MM y LM) fueron depositadas bajo un clima periglaciario; los niveles MM y LM se atribuyen a la glaciación Rissiense, no siendo segura aún la edad del nivel HM. La terraza baja, además del carácter periglaciario de sus sedimentos, se caracteriza por la desembocadura de diversos “dellen”, que también ofrece un argumento para atribuir su origen a la glaciación Würmiense. Capítulo 7: Descripción de las terrazas del Río Rubagón Existen diferencias considerables entre el Pisuerga y el Rubagón : la cuenca de éste es mucho menos extensa; las terrazas fluviales son, por consiguiente, menos grandes y se encuentran, además, en niveles más bajos, tanto en sentido relativo como absoluto. Pueden distinguirse cuatro niveles: La terraza HR Altura relativa 55—70 m „ „ MR „ „ 40—50 „ „ „ LMR „ „ 15—20 „ „ „ Baja „ „ 0—5 „ Están representadas en dib. 29, con el perfil longitudinal del Río Rubagón hasta su desembocadura en el Río Camesa. Los números de las terrazas en el texto corresponden con los en el perfil. La terraza HR se halla en las partes 4, 6 y 7. El espesor de la cobertura sedimentaria varía de unos 2 metros a seis o siete metros. Se compone el depósito fluvial de cantos de conglomerado y de arenisca gruesa Triásicos y cantos cuarcitosos; el diámetro de los mayores cantos excede los 70 cms. Aquí, lo mismo que en la cuenca del Pisuerga, se observan en muchos sitios pendientes de denudación con ángulos pequeños que se levantan suavemente sobre el nivel de la terraza alta. Más hacia el Sur en la comarca de Matalbaniega y Nestar, se presentan tres restos de una terraza alta, con alturas de 1000—980 metros. Como veremos más adelante, forman parte de la terraza alta del Camesa. La terraza MR se halla en las partes 3, 8, y probablemente, 1. Salvo éste último, estas partes están cubiertas de una capa sedimentaria de cantos, de un espesor de 2—3 metros. La terraza LMR se encuentra en las partes 2 y 9. También están cubiertas de una cobertura de cantos. La Terraza Baja se extiende desde Barruelo de Santullán río abajo, y localmente alcanza una anchura de más de 500 metros. La cobertura de cantos tiene un espesor de unos 2—4 metros. Capítulo 8: Petrografía sedimentaria de las terrazas del Río Rubagón La naturaleza litológica de los cantos está representada gráficamente en dib. 33, en el cual se ve que domina la cuarcita, mezclándose con los cantos del Triásico. Los índices de desgaste se dan en el dib. 34. Por la ausencia de conglomerados espesos que suministren cantos cuarcitosos ya rodados, son distintos los diagramas de dibs. 21 y 34. Sin embargo, puede concluirse que los cantos del sedimento HR demuestran un transporte fluvial de corta distancia, en el cual no hubo influenca glaciaria ni periglaciaria. La terraza LMR, al contrario, claramente indica una influencia periglaciaria. En la Terraza Baja también puede ser observada una influencia periglaciaria, pero ha sido menos importante que en el caso LMR. La granulometría de las muestras indica deposición bajo un régimen fluvial con grandes variaciones de caudalosidad. Véase dib. 35. El contenido algo mayor de la fracción “silt” (2—50 micrón) en las terrazas LMR y Baja puede atribuirse a la acción del viento. Los granos de cuarzo son generalmente angulares (dib. 36), con una excepción importante: la terraza MR, cuyo sedimento está bien rodado y como tal refleja el carácter periglaciario de su cobertura sedimentaria. Los minerales densos (dib. 37, cuadro 13) enseñan la predominancia de los minerales turmalina, circón y rútilo. El contenido de topacio de una parte de la terraza Baja fué causado por acarreo desde el Oeste, de la région Wealdense. Capítulo 9: Descripción de las terrazas del Río Camesa Sólo hay dos niveles de terrazas del Camesa: la terraza HC, de altura relativa, media de 60—75 metros, y la terraza baja. La terraza HC se halla, extendiéndose desde Mataporquera (dib. 38), en las partes 2, 4 y 5, con una afluente en el valle del Arroyo de la Canal (3), y en las partes de Matalbaniega. Está cubierta esta terraza de un sedimento de unos 10—12 metros de espesor; sólo en las partes superiores (Mataporquera y Arroyo de la Canal) no alcanza más de 6—8 metros. No hay terrazas intermedias. La Terraza Baja del Río Camesa es distinta de las de los Ríos Pisuerga y Rubagón, por no tener cantos en su superficie. Por el perfil longitudinal de la pendiente extremadamente baja, la potencia de erosión y transporte es casi nula. Los cantos, si los hay, se pierden en los depósitos turbosos del agua estancada. Capítulo 10: Petrografía sedimentaria de las terrazas del Río Camesa Por ausencia de afloramientos, no hemos podido tomar muestras de la Terraza Baja, y tampoco fué posible realizar análisis de los cantos. Así es que sólo se puede observar que los sedimentos de la Terraza Baja deben reflejar las características de la terraza HC, porque ésta se encuentra casi en todos los sitios sobre la terraza baja, en la ribera derecha. Los numerosos meandros indican que, si han estado presentes anteriormente, los restos de terrazas intermedias pueden haber desaparecido fácilmente por la erosión lateral de este valle bastante angosto. Así es que sólo hemos podido estudiar los depósitos de la terraza HC. En dib. 44 se presenta la naturaleza litológica de los cantos, de la cual se ve claramente la importancia de los cantos compuestos del Triásico. La influencia del Kío Rubagón en este sedimento se manifiesta en un aumento del porcentaje de cantos cuarcitosos. Los cantos cuareitosos que han sido encontrados en el valle del Arroyo de la Canal, en cambio, deben ser procedentes de bancos de conglomerado grueso cuarcitoso, que seguramente están presentes en el Triásico. En la dirección río abajo, observamos un aumento de desgaste de los cantos (dib. 45). Influencias periglaciarias resultan ausentes. De los análisis granulométricos (dib. 46A) se ve que la fracción de diámetro 〈 2000 micrones es bastante homógena. Los bancos arenosos bajo los cantos de la terraza también son de origen fluvial, y pueden ser más antiguos que la terraza HC. El desgaste de granos de cuarzo de 500—1050 micrones de diámetro está representado gráficamente en dib. 47. Son angulares, con muy pocas excepciones. Los minerales densos se han puesto en el cuadro 16. Son muy similares los caracteres fisiográficos de las terrazas HC del Camesa y de HP del Pisuerga. Por ejemplo, el espesor de las coberturas sedimentarias es casi igual en ambos casos; además, las dos terrazas se han desarrollado igualmente como “terrazas de plataforma”, y, salvo la naturaleza litológica de los cantos, son muy semejantes los caracteres petrografíco-sedimentarios. La terraza HR del Rubagón desemboca en la terraza HC, de tal manera que el “Rubagón Alto” debe haber sido un afluente del “Camesa Alto”. Llenaban los ríos juntos parte de la llanura, situada entre la Cordillera Cantábrica y el “Pays Plissé” (cotéjese Cap. 11). Capítulo 11: Superficies de planación Prerrodánico. Tras los movimientos tectónicos de la fase sávica en el centro de la Meseta y en las cordilleras marginales, se desarrolló la “Penillanura fundamental de la Meseta”, bien conocida de publicaciones de diversos autores, y discutida ampliamente por Solé Sabaris (1952). Ya antes del Pontiense existía esta penillanura, que se extendía ampliamente y que fué levantada y basculada por la fase rodánica. En Galicia, también han sido encontrados restos de la penillanura fundamental de la meseta, y según Stickel (1930) también estarían presentes en numerosos sitios en la Cordillera Cantábrica, por ejemplo en las comarcas del Puerto de Piedras Luengas. Nosotros, sin embargo, no hemos observado ninguna indicación de tal penillanura en este sitio. Puede ser que se encuentre más al Oeste, pero en la región investigada por nosotros, seguramente falta en la actualidad. Postrodánico. Después de los movimientos rodánicos, la erosión formó otra vez amplias superficies de planación, bajo un clima árido o semi-árido; son pedimentos, claramente visibles en muchas partes de España. Al Sur de la Cordillera Cantábrica, se desarrolló un pedimento del cual se reconocen ahora los restos al Sur de la villa de Guardo. Sobre los pedimentos se hallan coberturas de derrubios, generalmente cantos angulares o mal rodados, las rañas. Hasta ahora las rañas y los pedimentos fueron considerados como siendo de la misma edad, pero recientemente, Mensching (1958) pronunció la posibilidad de que los pedimentos fuesen de más edad, e.d. del Pliocénico, que las rañas, que tienen edad Villafranquiense. Al Sur de la Sierra del Brezo se presenta un fenómeno similar: existe una llanura, cubierta de una brecha calcárea. Es el único sitio donde se hallan sedimentos con derrubios de la Caliza de Montaña en la región que hemos investigado. Probablemente, esta llanura es de la misma edad y del mismo origen que las rañas, es decir de la época Villafranquiense. En nuestra región, existen numerosos restos de superficies de planación que, sin embargo, no tienen carácter de pedimento y sobre los cuales tampoco se hallan derrubios angulares. Hay más razones para no considerarlas como pedimentos. Están claramente relacionadas con las rocas de poca resistencia, y, por tanto, la planación debe haber originado de los valles de un sistema fluvial subsecuente. Pero como son más antiguas que las terrazas altas, también deben ser de edad Villafranquiense. Todos los restos de superficies de planación son evidentemente partes de una superficie, o puede decirse que todas las partes son de la misma edad. La superficie está situada más alto en la llamada superficie de Muda (véase mapa 1: A), bajando hacia el Sureste. Para facilitar la descripción, hemos indicado las partes individuales con nombres de pueblos situados en estas partes. Sólo el nivel de Redondo parece formarse activamente hasta ahora; puede ser que originalmente fuera de la misma edad que las otras, pero ahora existe una diferencia con éstas, que son fósiles. Capítulo 12: Morfogénesis Después de las fases orogénicas hercínicas, la Cordillera Cantábrica ha tenido una historia muy compleja. Los efectos de las orógenas terciarias se muestran en la plegadura de los sedimentos Mesozoicos marginales alrededor del bloque meseteño, y en los movimientos epirogénicos del mismo. Así se formaron las depresiones castellanas y la Cordillera Central (Solé Sabaris, 1952). El Terciario al Sur de la région investigada se presenta como dos series de conglomerados: una de cantos de calizas Cretaceicas, de edad probablemente Eocena u Oligocena, y otra de cantos cuarcitosos de edad Miocena. Según Mabesoone (1959), el conglomerado inferior, de cantos calicíferos, fué depositado después de la fase pirenaica, y plegado en la fase sávica. Después de esta fase, continuó inicialmente la entrega de cantos de caliza, que posteriormente fueron sustituídos por cantos cuarcitosos. Después, el tipo de sedimentos fué haciéndose más fino. Pero de esto no puede concluirse que existiera un relieve llano en la Cordillera Cantábrica. Tras la fase rodánica, que causó el levantamiento del bloque meseteño y su basculación, por la que se formaron las grandes arterias fluviales de la meseta que se dirigían hacia occidente, se inició en muchas partes de España la pedimentación, como ya hemos indicado en el capítulo precedente. En nuestra región, la planación tenía otro tipo, pero también es de edad Villafranquiense. En el Villafranquiense superior, el régimen fluvial cambió de tal manera que los ríos tuvieron el carácter de “braiding rivers”, que depositaban importantes masas de cantos en las llanuras intramontanas, que ya existían como resultado de la planación. Había, en aquella época, el sistema del Pisuerga Alto, y el del Camesa Alto, del cual el sistema del Rubagón Alto era un importante afluente. No existía una conexión entre los dos sistemas. Posteriormente, el Pisuerga Alto fué capturado por un afluente del sistema del Camesa Alto, que tenía gran potencia erosiva, por pasar, en un tramo subsecuente, por rocas de poca resistencia. Luego, en tiempos de clima glaciario o periglaciario, se depositaron las terrazas intermedias y bajas. La terraza baja es de edad Würmiense, los niveles LM/LMR y MM/MR son de edad Rissiense, no siendo segura aún la edad del nivel HM, e. d. o de Rissiense antiguo, o Mindeliense. Las formas de relieve glaciares, en esta región, no tienen gran importancia, las periglaciares son los bloques, los “dellen”, que se hallan en dos tipos, y la soliflucción. Hablando geológicamente, en el futuro próximo, una captura del sistema Rubagón/Camesa superior por el Arroyo Mardancho, afluente del Ebro, tendrá lugar en Quintanilla de las Torres. Se predice, asimismo, una captura del tramo superior del Ebro por el Río Besaya cerca de Reinosa. Así le quedará claro al lector, que las modificaciones de sistema fluvial que hemos establecido en el pasado, no serán las últimas; en el futuro geológico, si la naturaleza puede actuar libremente, se producirán modificaciones igualmente importantes.

    Beschreibung: The main purpose of this study is to search for an explanation of the curious differentiation within the genus Chamaeleo. Since the species of this genus are rather doubtful units, I have studied the geograpical distribution of characters, not of the species, a method first used in botany (BAUR, ROTHMALER a.o.). I found that the number of characters is largest in east Afrika, gradually decreasing from this area to the periphery of the total range of the genus. East Africa proved to be still more important, as practically all the characters occur in it. This means that the chameleons in the other areas practically never possess characters that are not found in east Africa. This pattern of distribution fits in rather well with REINIG’S elimination theory (1938): „.. bei Einzelwanderungen wird nur ein Teil des gesamten Allelbestandes einer Art mitgeführt... eine durch Einzelwanderung entstandene Population weist eine geringere Zahl von Allelen auf als die Ausgangspopulation.” The existence of many parallel series of variation (meaning that several characters originated several times independently in different groups) led me to the conclusion that the mechanism described in REINIG’S theory as elimination, has consequences also for the genes predisposed to change into others. This reasoning gave a key to the reconstruction of the ancestral chameleon. By two different ways I arrived at the same conclusion, viz. the ancestral chameleon was probably an animal resembling mostly Chamaeleo chamaeleon s.l. (§ 21). As for this theoretical part of my study a survey of the species was needed, I first made an attempt at a natural system. I have divided the genus into groups of related species. For practical reasons the chameleons of Madagascar are treated separately. Their connections with the species of the African continent are examined in a special section (§ 11). As a result of my investigations I had to propose the following taxonomic changes: Ch. rhinoceratus var. lineatus + Ch. labordi + Ch. voeltzkowi + Ch. barbouri = Ch. rhinoceratus (§ 3), Ch. lambertoni = Ch. lateralis (§ 4), Ch. semicristatus = ♀ Ch. verrucosus (§ 5), Ch. guibei nov. spec. (§ 6), Ch. calcarifer = Ch. chamaeleon calcarifer, Ch. zeylanicus = Ch. chamaeleon zeylanicus, Ch. etiennei = Ch. gracilis etiennei (§ 12), Ch. anchietae vinkei + Ch. anchietae mertensi + Ch. marunguensis = Ch. anchietae (§ 13), Ch. unicornis = Ch. oweni unicornis (§ 14), Ch. pumilus = Ch. pumilus pumilus, Ch. melanocephalus = Ch. pumilus melanocephalus, Ch. gutturalis = Ch. pumilus gutturalis, Ch. ventralis = Ch. pumilus ventralis, Ch. ventralis occidentalis = Ch. pumilus occidentalis, Ch. ventralis karrooicus = Ch. pumilus karrooicus, Ch. damaranus = Ch. pumilus damaranus, Ch. caffer = Ch. pumilus caffer, Ch. taeniobronchus = Ch. pumilus taeniobronchus. (§ 16).

    Beschreibung: In an adult female of the common eel Anguilla anguilla a large lipoma was found, situated on the left side, caudally of the left operculum. Microscopically, the tumour, which originated from the subcutaneous connective tissue, was composed of areas of adipose tissue and areas of fibrous connective tissue. The tumour belongs to the fibrolipomatous type and shows a striking resemblance with the lipoma, described by Stolk (in press) in the lizard Lacerta muralis.

    Beschreibung: Bij een inventarisatie van de binnenduinrandbossen der landgoederen van Wassenaar op 13 mei 1959 ontdekten wij tot onze grote verrassing, tezamen met Dr. J. Wilcke en Ir. W.F. Rappard, op bet landgoed Groot Haesebroek een rijke groeiplaats van Poa chaixii, Luzula luzuloides en Luzula maxima. Deze soorten komen overigens vrijwel uitsluitend voor in het oosten en zuiden des lands. Poa chaixii, ook in het O. en Z. zeldzaam (met Amersfoort als westelijkste, groeiplaats; door ons alleen gezien hij Oldenzaal, Berg en Dal, Oosterbeek en Gennep), is in het westen tot dusver slechts éénmaal waargenomen (Bolnes: wijlen Dr. P. Jansen). Luzula luzuloides, vrij algemeen in Zuid-Limburg en zeldzaam in het subcentreuroop district, is daarbuiten slechts waargenomen in het Haagse Bos, anderhalve eeuw geleden (Van Geuns: zie van Hall, Flora Belgii Septentrionalis); volgens de heer G. Londo te Haarlem (mond. med.) zou zij echter thans nog voorkomen onder beuken aan de binnenduinrand te Bloemendaal. Luzula maxima, eveneens vrij algemeen in Zuid-Limburg en zeldzaam in het subcentreuroop district, is daarbuiten bij ons weten nooit vermeld.

    Beschreibung: Tijdens een bezoek van de Natuurwetenschappelijke Commissie van de voorlopige Natuurbeschermingsraad aan het eiland Rottum op 28 juli 1958 verzamelde Dr. W. Vervoort, Leiden, een 47-tal Phanerogamen. Dit was voor ons aanleiding om na te gaan, wat er tot nu toe over de flora van Rottum in de Nederlandse literatuur gepubliceerd was. Oude gegevens hierover vinden wij in een artikel van L.A. Cohen in het Tijdschrift voor Natuurlijke Geschiedenis en Physiologie 7, 1840, p. 445, getiteld Berigten omtrent de natuurlijke geschiedenis van het eiland Rottum. Daarna volgt in 1870 het bekende werk van P. Holkema, De Plantengroei der Nederlandsche Noordzeeeilanden. De volgende publicatie over de flora van Rottum is van W.W. Schipper, on wel in N.K.A. III,1 , 1897, p. 209 en in idem, 1898, p. 358. Vervolgens vinden we nog van J.P. Thijsse enkele in hoofdzaak ornithologische artikelen in De Levende Natuur, waarin echter ook enige gegevens over de plantengroei te vinden zijn en wel in D.L.N. 15, 1911, pp. 385 en 405, D.L.N. 16, 1911, pp. 193, 217 en 241, D.L.N. 17, 1912, p. 193, D.L.N. 21, 1916, p. 215 en D.L.N. 22, 1917, p. 185.

    Beschreibung: Op boomkwekerijen, waar men zaad van deze heester, zowel uit de duinen als uit het Alpengebied uitzaait, ziet men een duidelijk verschil tussen de duin- en do Alpenplanten. Hoewel beide variëren, zijn die uit de duinen voorzien van meer doornen, breder blad en grotere vruchten. Onze landgenoot, Prof. J.L. van Soest heeft ze beschreven als ssp. maritima en ssp. fluviatilis (Mitt. der Florist. -sociolog. Arbeitsgemeinschaft N.F. 1952, Heft 3).

    Beschreibung: Op 16 mei vond ik in de gemeente Wilnis op de westhelling van de Westveense kade van de Kromme Mijdrecht een vrij dichte vegetatie van Carex reichenbachii. Volgens de auteurs van de Flora Neerlandica (I, 3, 1954) „is de plant zeker vaak over het hoofd gezien.” Dit is wel aannemelijk, omdat de habitus doet denken aan Carex ligerica of aan een nog niet volgroeide C. brizoides op overeenkomstige standplaatsen. Maar in het onderhavige geval, waarbij een soort van de sectie Arenariae (behalve dan C. disticha) op een kade in het Hafdistrict werd aangetroffen, voelde ik mij door deze merkwaardige groeiplaats wel gedwongen, de plant wat nauwkeuriger te onderzoeken. Onmiddellijk vielen daarbij de gekromde aartjes op, De determinatie gaf, hoewel de urntjes nog niet volledig ontwikkeld waren, geen moeilijkheden. De heer Th.J. Reichgelt bevestigde de juistheid ervan.

    Beschreibung: Hen inwoner van Leiden met belangstelling voor floristiek loopt gevaar om te versomberen. Hij heeft in zijn omgeving de min of meer vaste vindplaatsen van een hoogst bescheiden aantal zeldzame planten, waarmee hij eventuele gasten van elders desgewenst, in het juiste seizoen, kan confronteren, maar overigens leeft hij vrijwel te midden van een tot wanhoop drijvende cultuursteppe, enkele moeilijk toegankelijke terreinen (Kaaggebied!) niet te na gesproken. Wanneer zulk een florist zijn gedrukte stemming eens extra wil accentueren bladert hij in Molkenboer en Kerbert’s Flora Leidensis. Hij verneemt daaruit hoe anders zijn ervaringen zouden zijn uitgevallen indien hij omstreeks 1840 geleefd had. (Zijn gemoedstoestand brengt mee, dat hij daarbij liefst over het hoofd ziet, dat de moderne handige determineerboekjes toen nog niet bestonden). M. & K. toveren hem een fraaie wereld voor. Op de koren- en vlasakkers van de Hoge Mors en langs de legendarische Duifhuislaan was het kennelijk om te watertanden en ook van andere plaatsen worden de in onze ogen vreemdste vondsten vermeld. Wellicht op grond van de schilderachtige naam treft hem daarbij de herhaalde vermelding van de Morsebel-polder onder Oegstgeest. „Carex caespitosa L.”, zo leest hij, maar hij troost zich, aan de hand van Flora Neerlandica deel I, afl. 3, blz. 89, met de gedachte, dat het wel Carex nigra (L.) Reichard zal zijn geweest, die er trouwens nu nog staat. Verder stuit hij op Medicago muricata D.C. (wat dat ook raag zijn!), Montia fontana L., Aster tripolium L., Myosurus minimus L. en Fritillaria meleagris L.; de laatste heide „in menigten”. Met welbehagen stelt hij daartegenover vast, dat Samolus valerandi L. ter plaatse aan de toenmalige floristen is ontsnapt of zich pas later heeft gevestigd.

    Beschreibung: Ferns are by far the largest division of vascular cryptogams, and, for purposes of publication of Flora Malesiana, they will have to be subdivided in a series of parts. This necessarily raises the problem of taxonomic subdivision of ferns into families or other major taxonomic units, a matter on which there is at present no general agreement among pteridologists, except that the more primitive families are generally recognized as distinct groups. As regards the majority of ferns therefore no formal arrangement into families will be attempted. There is however a fairly general agreement that certain groups of genera (e.g. the Davallia group) are natural groups. It is the intention to arrange the genera of ferns in such groups, and to publish the group-revisions in such sequence as may be most practicable. The author of the revision of any particular group must naturally decide the limits he will recognize for the group; and as the whole work will be by more than one author, some differences of opinion as to the delimitations of groups are probably unavoidable. It is believed that such differences of opinion will not be great, and if they occur their existence will be indicated by cross-references.

    Beschreibung: Commemoration of the 250th anniversary of the birthday of Linnaeus. In many places academies and societies commemorated this event. In Sweden, Uppsala University, it took place just before the End of Term ceremonies of the University and a number of botanical and zoological taxonomists were invited to a Symposium ”Systematics of To-day”, to excursions in the vicinity of Uppsala, and to the imposing End of Term ceremonies, attended by His Majesty, The King. On that occasion several famous taxonomists received an honorary doctorate from the University. The festivities were concluded by a dinner and ball in the magnificent Rikssaal of the Uppsala Castle. For those who, like myself, had the privilege to attend and enjoy the abundant hospitality and friendliness in this beautiful country, these spring days will forever linger in the memory as delightful from all points of view. To observe flowers along the same trail the Prince of Botanists took with his students centuries ago, to visit Hammarby under delightful weather conditions, gave a peculiar charm to these days; we feel immensely indebted to our hosts, male and female, all gentle, eager, courteous, dignified, and above all, kind.

    Beschreibung: Small to medium-sized, rarely large, terrestrial or epiphytic ferns. Rhizome creeping, terrestrial and radially symmetric or nearly so, solenostelic or more often with a special type of protostele with internal phloem but without internal endodermis and medulla; or epiphytic and with a similar but strongly dorsiventral protostele with the internal phloem close to the dorsal side of the xylem, or in some small species the xylem strand open and U-shaped. Petioles with a single U- or V-shaped vascular bundle. Indument of the rhizome of scales, these nonpeltate, non-clathrate (in Mal. spp.), glabrous, entire, or with weakly developed teeth of two protruding cell-ends; terminal cell of scale glandular. Juvenile leaves with similar but narrower, caducous scales. In some species some or even all scales are entirely uniseriate but not true hairs. Laminal parts with scattered microscopical two-celled hairs, hardly ever with macroscopically visible hairs. Axes of leaves adaxially with a single groove bordered by ridges, both mostly continuous with those on axes of different order. Lamina once pinnate to decompound (rarely simple in a single Old World sp.), anadromous. Ultimate divisions various, often dimidiate. Veins free, or reticulate without free included veinlets, not reaching the margin. Sori terminal on one to many veins, often on a commissure ± parallel to the margin, submarginal, indusiate; indusium attached at its base, the sides free or adnate, the free edge next to the leaf-margin and often ± equaling it. Sporangia ± long-stalked, with a triseriate stalk; bow of annulus interrupted; stomium well differentiated or not. Spores trilete or less often monolete, without perisporium, smooth or with little sculpture. Paraphyses mostly, perhaps always, present, filiform, 2- to many-celled, often early disappearing. Gametophyte known in very few species, cordate. Distribution. Pantropic, extending considerably beyond the tropics in Japan, Australia, South Africa, and eastern South America; comparatively weakly represented in continental Africa. Six genera: Odontosoria (10 American spp., 2 African spp.), Ormoloma (2 spp., neotropical), Tapeinidium (17 spp., SE. Asia to Samoa), Sphenomeris (11 spp., pantropic-subtropic), Xyropteris (monotypic, Malesian), and Lindsaea (c. 150 spp., pantropic-subtropic).

    Beschreibung: Rhizome relatively slender, creeping, protostelic (solenostelic only in Dicranopteris pectinata (WILLD.) UND. of tropical America), in Stromatopteris bearing erect irregularly dichotomous branches which bear the fronds, in all other cases bearing fronds directly; young parts covered with peltate fringed scales (scales otherwise in Stromatopteris) or branched hairs. Fronds unbranched in Stromatopteris, in all other cases branched in fully developed plants, the main rachis bearing a series of pairs of branches, its apex periodically dormant while each successive pair of branches develops; each primary branch often bearing a pair of secondary branches and a permanently dormant apex between them, the process sometimes repeated several times; ultimate branches either bipinnatifid or pinnatifid, the lamina (whether of an ultimate branch, or leaflet of an ultimate branch) cut almost to the costa; veins in lamina-segments pinnate, branches simple or forked, free (in some cases apparently joining a thickened non-vascular margin).

    Beschreibung: The author regards the Cyphellaceae as an artificial family. He redefines it for practical purposes, suggesting the gradual removal of those elements that show relationship with other groups; several elements are referable to the Corticiaceae or the agarics. A list of the ‘cyphellaceous’ generic names tentatively included is given. The genera to be excluded from the family as defined are briefly discussed. The same applies to a long series of specific names that had or have been included. A historic chapter reviews some important developments in regard with some of the older genera, Solenia, Cyphella, Aleurodiscus, as well as the rise of the family. Some species are transferred to Aleurodiscus Rab. ex J. Schroet.; Cytidia Quél. is redefined and Auriculariopsis Maire excluded from it. Other genera reviewed and redefined are Stromatoscypha Donk [Porotheleum (Fr. per Fr.) Fr.], Chromocyphella De Toni & Levi Phaeocyphella Pat.], and Lachnella Fr. Two new monotypic genera are introduced, Cellypha Donk and Pellidiscus Donk. One or more species of the redefined and new genera are discussed. The name Mycena sect. Hirsutae (Kühner) ex Donk is validly published. Several specific names are reduced to the synonymy of other species for the first time. Several types of names published by Persoon and by von Albertini & von Schweinitz were studied. New combinations are made under Hymenochaete Lév. (1), Favolaschia (Pat.) Pat. (1), Aleurodiscus (2), Cellypha (1), Pellidiscus (1), Chromocyphella (1).

    Beschreibung: The fossil remains of rodents described in the present paper are from various localities. The large extinct musk rat Megalomys occurs in reddish-brown phosphatic “oolite” fillings of irregular cavities in a marine limestone found by Mr. P. H. DE BUISONJÉ in the north-western part of the Duivelsklip, eastern Curaçao, about 50 m above sea-level. The “oolite” also contains scanty remains of lizards, snakes, and of a bat. Fragmentary molluscs present possibly include Cerion uva (L.), a recent, very common, terrestrial species, as well as other gastropods, many opercula of which were found. Samples of a phosphatic “oölite” deposit collected in 1937 by Dr. P. WAGENAAR HUMMELINCK from an escarpment near Fontein, Bonaire, proved to contain jaws, with teeth, of a genus of hesperomyine rodents, Thomasomys a single snake vertebra; and mollusc remains including what seem to be their coprolites.

    Beschreibung: Sediments in the foreland of a mountain chain are sometimes suited to reconstitute the conditions in these mountains at the time of deposition of the sediments. The present study gives the results of a sedimentological investigation of the Tertiary and Quaternary deposits in a part of the Duero basin, situated south of the Cordillera Cantabrica, which supplied the sediments. The aim was to determine both the conditions in the source area, and the environments in the area of deposition. The investigated area is situated in the province of Palencia, between the rivers Pisuerga and Carrión. The area being a part of the so-called Meseta, has a simple relief. Two levels at different heights can be distinguished. The higher level, páramo, is strikingly flat, the lower, campiña, is more undulating. The Tertiary basin sediments are of various types, and can have six different facies. Along the mountain foot the sediments are chiefly conglomerates with some sandstones, united into the Cuevas facies. The pebbles consist of limestones derived from the Cretaceous limestones, which in the E occupy extensive areas but in the W are only exposed in a narrow strip along the southern border of the mountain chain. At that time they must have formed the southern flank of the Cantabrian Mountains. Pebble roundness and flatness indicate for the greater part a deposition as river fans in a warm and rather dry climate. These conglomerates have been brought into an overturned position in the W of the investigated area, and were strongly tilted in the E. This tectonic deformation is thought by several authors to have occurred during the Savian orogenic phase. The younger beds, having the Cuevas facies, are nearly horizontal, and were deposited during and after this folding as appears from the presence of sandstone pebbles derived from the sandstone layers within the folded conglomerates. South of the limestone conglomerate belt a wide zone with red beds occurs. These sediments, consisting of an alternation of quartzite conglomerates and sandy layers, represent the Vega de Riacos facies. The change of deposit from a limestone conglomerate into a quartzite conglomerate may be due to changes in the supply area, the Mesozoic limestones having been eroded and having become covered with soils, and the Palaeozoic quartzites and conglomerates becoming largely exposed. A typical feature is the absence in all basin sediments of pebbles derived from the Carboniferous limestone, the so-called Brezo-limestone, which at present froms a great part of the southern flank of the Cantabrian Mountains. The sediments presenting the Vega de Riacos facies were deposited in a warm and humid monsoon climate, as appears from (1) the red colour, (2) the shape of the quartz sand grains, and (3) the clay mineral associations. The remainder of the investigated area is characterized in the N by yellow sandy and clayey deposits, covered by similar, but yellow and red, sandy and clayey deposits, and in the S by yellow clayey deposits overlain by white and grey gypseous marls, alternating with limestones. The underling yellow sandy and clayey sediments, typical for the Carrión de los Condes facies, are dated as Vindobonian on account of the fossils found near Palencia and Saldaña. The upper yellow and red, sandy and clayey layers found in the N, having the Relea facies, have a Pontian age, based on fossils found near Saldaña and Relea. In the E of the investigated area this Relea facies shows a local divergent aspect, called Zorita facies, characterized by an alternation of red, sandy deposits and white, marly deposits. The gypseous marls and the limestones in the S, which show the Páramos facies, overlying the yellow clayey sediments in Carrion de los Condes facies, have a cover of a very hard, bluish limestone, the Páramos-limestone, which provided some freshwater molluscs indicating also a Pontian age. The sediments in the four last-named facies represent chiefly deposits of rivers and shallow temporary lakes (lagunas). A rather regular sedimentation went on from Vindobonian into Pontian times, meanwhile influenced by changes of climate in the basin. After the warm and humid climate in which the red beds were deposited, the climate became more arid, with an increased evaporation. First the yellow sediments in Carrión de los Condes facies were deposited, in the N being still sandy, in the S becoming more clayey. They are clearly deposits of rivers which did not supply very coarse material, but some deposition in temporary lakes must also have occurred. At the end of the Vindobonian evaporation became stronger, as can be concluded from the lime crusts found in the upper layers in the area of the Carrión de los Condes facies, and more to the S, in the area of the Páramos facies, from the deposition of gypsum bearing marls, when the drainage was more or less restricted. This climate persisted during the first part of the Pontian as can be concluded from lime crusts occurring in the lower beds in Relea facies, the depositional environment, that is rivers and lagunas, remaining the same. Later in the Pontian the humidity of the climate increased, as appears from the increasing number of red layers in this Relea facies. In the S this increasing humidity caused the precipitation of gypsum to cease, and at this time the Páramos-limestones were formed. The Zorita facies, which laterally replaces the Relea facies, is chiefly determined by a supply from a different source area, namely the Mesozoic calcareous rocks exposed a few kilometres N of the deposits in Zorita facies. The heavy mineral associations (chapter VIII, part 1) are monotonous, practically consisting of resistant minerals. They seem to indicate a supply from NW to SE. Also the pebble supply followed this direction, as may be concluded from their size distribution within the red beds having the Vega de Riacos facies. This NW—SE direction was the main drainage direction in Pre-Rhodanian times. The clay minerals in the sediments presenting the various facies allow to draw some conclusions on the climates at the times of deposition. For instance, the rather righ percentage of kaolinite in the sediments in the Cuevas and Vega de Riacos facies, may indicate a warm and rather humid climate during and after deposition. But later alterations also influenced the clay mineral associations, causing a preponderance of illite (see chapter VIII, part 3). After the deposition of the Páramos-limestones the Duero basin became a non-depositional area. During the Rhodanian orogenic phase the bordering mountains were uplifted, and the basin was tilted towards the W. This caused a switch of the drainage pattern which before was directed towards the Mediterranean, and now became directed towards the Atlantic Ocean. During the whole of the Pliocene strong bevelling occurred, through which the páramolevel in the basin and pediments at the foot of the mountain chains were formed. Next, a warm and dry climate characterized by sheetfloods must have prevailed all over the Meseta, causing the deposition of the angular quartzitic raña pebbles, so well exposed in the investigated area on the raña of Guardo. These rañas are presumed to be of Villafranchian age. Soon the influence of Quaternary changes of climate became evident. Certainly the younger river terraces, found at five various levels, are due to these Pleistocene climatic changes. Pebble analyses could confirm the opinion of various authors who admit only two real glaciations in the Spanish mountains, namely the last and the penultimate. Indeed, the two lower terraces contain pebbles which may have been formed in a periglacial climate, whereas the deposits of the three upper terraces only contain evidences of a humid, temperate climate. The sedimentological data on which the conclusions on the depositional environments, as given above, are based can be found in the following chapters: (a) grain size distribution (chapter V), (b) pebble analyses (chapter VI), (c) morphometrical sand analysis (chapter VII), (d) mineralogy of the sands (chapter VIII, parts 1 and 2), (c) clay minerals (chapter VIII, part 3). The development of the drainage pattern (see chapter IX) was reconstituted with the help of a number of captures, which can be observed in the field. In this way a gradual adjustment of the drainage to the present direction can be demonstrated. In the investigated area this adjustment occurred rather late during the Quaternary. At that time also the campiña-level was formed. Finally, in the last chapter (X), an attempt is made to establish the palaeoclimates, and the relief in the source area, though there remain many uncertainties. The Cordillera Cantabrica, being a mountain area, must always have had a more humid climate than the basin. Even during the Upper-Vindobonian and Lower-Pontian, while the basin was arid, the climate in the mountains must have been more humid. This appears from the clastic sediments supplied into the basin (Relea facies). Though the drainage was restricted, it will not have been totally interrupted, because only calcite and gypsum were deposited in the basin centre, and no halite. There will have been a certain relief in the source area during the whole time. The sediments give no indications for a fully developed peneplain. During the whole of Vindobonian and Pontian times clastic sediments have been supplied by the Cantabrian Mountains.

    Beschreibung: The present paper deals briefly with the main geological features of the Casavegas area (Northern Palencia, Spain). Though incomplete, the sequence of Carboniferous strata in this region is regarded as a reference-section for correlation purposes within the larger N. Palencia area. A local subdivision on fusulinids of a part of the Carboniferous is proposed. Three zones are distinguished: Protricites Zone F. ex gr. brañoserae Subzone Fusulinella Zone F. delepinei Subzone Profusulinella Zone Fusulinella bocki, var. delepinei is brought to species level as F. delepinei Van Ginkel, sp. nov.

    Beschreibung: Desde el punto de vista geológico el norte de Surinam se divide en 4 zonas distintas, a saber: I°. la parte del sur que pertenece, como también el resto de Surinam, a la capa precambriana de Guyana, que, a su vez, consiste principalmente en granitos, granitodioritas y esquistos, y que, por la mayor parte, lleva selva pluvial en terrenos corroídos muy profundos. 2°. Al norte de esta capa se encuentran depositaciones mucho más jóvenes: la capa de la formación Zanderij, constituida por arenas blanqueadas con vegetaciones de sabana y, además, arenas no blanqueadas y arcillas con arena gruesa. 3°. Luego hay la formación Coropina de la vieja llanura costera o sea un viejo terreno de bajiales compuestos de limos polvorosos y arcillas con formaciones de pantano y de lodazal. En la franja del norte se encuentran cordones litorales de arena fina (llamados en Surinam „ritsen”). 4°. Finalmente, desde allí hasta la costa actual la joven llanura costera que consiste en arcilla pesada marina con formaciones de pantano y cordones costeros de arena o conchas, cubiertos de selva (véase el mapa). Tipos de vegetación en lugares húmedos: 1. Manglar, que se divide en selva de Avicennia nitida (la parwa) en la costa y en los diques naturales de los ríos grandes, zonas de Rhizophora mangro: 3 especies) en barro a lo largo de las orillas de los ríos, y el manglar mixto. 2. Pantanos herbáceos, que contienen muchas comunidades en agua salina y dulce, descritas en la parte primera de esta serie. 3. Bosque de pantano, que varía desde matorral abierto hasta bosque de un estrato de 10—15 m. de altura y que es muy pobre de especies. Matorral de Machaerium lunatum (brantimakka) y bosque de Erythrina glauca (koffiemama) en agua salobre, y en agua dulce bosque de Pterocarpus y Tabebuia. 4. Selva de pantano tiene un dosel de entre 18 y 30 m., es pobre de especies y, ordinariamente, tiene numerosas palmeras; dicha selva se distingue en 3 tipos: El tipo A tieno mucho Triplaris (mierenhout) y ningún Symphonia (matakki) yes muy corriente en la joven llanura costera (perfil 1). El tipo B no tiene Triplaris, pero mucho Symphonia y Virola surinamensis (baboen) y se encuentra en las partes de más edad de la joven llanura costera; la formación de turbera es muy intensa. (perfil 2). El tipo C es como B, pero es más rico en especies en las partes más bajas de la vieja llanura costera, o sea en albercas detrás de los diques naturales de los ríos. Selva de lodazal es bastante rica en especies, tiene 2 estratos y se da en terrenos periódicamente inundados, como p.e. los témpanos erosionados de la vieja llanura costera, las partes bajas de los „ritsen”, los diques naturales de los ríos y en las aroyaderos en los terrenos accidentados. Característicos son los „kauwfoetoes”, que son suelos desiguales y canalados; la capa herbácea está, casi siempre, bien desarrollada, las varias palmas se dan con un número muy cambiante. En la selva litoral éstas pueden hasta dominar en el dosel de copas. Selva de Mora (perfil 3) es una variante alta de la litoral (de 35—40 m. de altura), en la que predomina Mora excelsa en todos los estratos y que se halla solamente en la parte occidental de Surinam. La de Hura crepitans (perfil 4) predomina aquí y allí en las partes bajas de los „ritsen” y hacia el oeste de la llanura costera se aumenta el número de Carapa formando así la variante tercera: la de Carapa. Formas xeromórficas de vegetación; En Surinam se resumen las formas xeromórficas de vegetación bajo el concepto de „sabana”. Dichas formas se dan en los sitios donde el suelo tiene tan poca capacidad retentiva del agua que en los períodos secos, cuando la evaporación supera con mucho la caída pluvial, aparece falta de agua y la vegetación se hace susceptible para incendios. Según el tipo de suelo distinguimos 3 series en las que la duración del período de falta de agua determina el aspecto de la vegetación. 1. la serie seca en arena profunda de cuarzo blanco muy permeable que lleva varios tipos de selva, a saber: Selva de sabana, de 25—30 m. de altura, dosel cerrado y un estrato inferior de árboles delgados; es rica en especies por el hecho de que hay muchas de la selva pluvial, al lado de las típicas de la de sabana, especialmente en el estrato inferior; las palmas que se den son pocas y pequeñas (perfil 6 p.p.). Aquí y allí se encuentra selva de wallaba con Eperua falcata, y selva de dakama con Dimorphandra conjugata como especie predominante. También se da el caso de 2 especies prevalecientes. Bosque de sabana se compone solamente de especies xeromórficas de sabana y se convierte, en caso de persistente falta de agua, en matorral con más o menos las mismas especies, para pasar a ser luego sabana abierta con grupitos de arbustos y una vegetación ligera y pobre de hierbas y semiarbustos. 2. la serie húmeda en terrenos llanos con capas impermeables en el suelo, de mode que, por consiguiente, carencia de agua en el período seco alterna con inundaciones en el de lluvias. Las formas forestales de sabana húmeda tienen en común muchas especies con las de la serie seca, aunque no dejan de tener algunas propias. Además tienen una subvegetación de hierbas grandes (Scitamineae). La sabana abierta húmeda lleva una vegetación rica, pero bastante cerrada, de especies propias. 3. la serie de piedra en suelos tenues que se encuentran sobre roca sin corroer en terreno accidentado y montañoso. Así hay p.e.: Selva de sabana montañosa en capas de ferrita y ferrobauxita en los montes, que se parece a la de sabana corriente, pero se caracteriza por otras especies, sobre todo Myrtaceae y Sapotaceae, y muchas lianas, musgos, y epífitas pequeñas. Sabana de roca se halla en masas de roca desnuda en el interior del país, p.e. en la montaña de Voltz sobre la cual crecen algunas hierbas en cavidades y hendiduras, sucedidas por grupos de arbustos en los que predomina, muchas veces, una de las especies de Clusia. En el sistema de BEARD la 1a y la 3a constituyen 2 series paralelas de las formaciones siempreverdes secas, mientras que la 2a entra en las formaciones de lodazal. La selva de tierra firme o la selva pluvial comprende los tipos que cubren la parte mayor de la superficie; sin embargo, no se las puede subdividir a causa de su grande riqueza de especies y su complejidad. En su forma óptima en la parte oriental del terreno accidentado esta selva constituye una de 3 o 4 estratos: uno, superior, de „emergentes” esparcidos, de 40—45 m. de altura; otro con un dosel irregular, bastante cerrado de una altura entre los 25 y 30 m.; y debajo del segundo un tercer estrato de árboles delgados y una subvegetación vaga, pero con especies propias, al lado de ejemplares jóvenes de las de estratos superiores. Palmas, generalmente, son numerosas, y en particular en la subvegetación (perfiles 5 y 6). Hacia el oeste y la costa el estrato superior desaparece poco a poco, quedándose más abiertos los inferiores, como pasa también en la selva veranera siempreverde de BEARD, lo cual, esto no obstante, no hemos distinguido, por haber una conformidad grande de especies. También la selva de „rits” en la llanura costera pertenece, según nuestro modo de ver, a los tipos más pobres de la selva pluvial. Sólo en una franja estrecha de 1—2 km esta selva se hace tan pobre e irregular, aunque tiene algunas especies propias como un cacto gigantesco (Cereus sp.), la espinosa Ximenia americana, la palma Astrocaryum segregatum y Eugenia wullschlaegeliana, que es mejor hablar de bosque costero. Al este de la Coppename predomina, aquí y allí, la Mora gonggrijpii (moraboekea) en todos los estratos. Completamente aparte está, a causa de su aspecto, la selva de lianas en la que faltan estratos y, no pocas veces, el dosel de copas por el hecho de que los árboles se encuentran muy dispersos. Bien es verdad que hay árboles altos, cubiertos de lianas que llenan también los espacios intermedios. La selva susodicha se encuentra en suelos pedrosos que hace difícil la radicación. Por consiguiente son muy numerosos los árboles caídos a tierra. Dicha selva cuenta con muchas especies que se dan también en la selva pluvial. Para los tipos de selva se suministran ejemplos de la fracción frecuentativa de las especies, y para la selva de arroyo y selva pluvial se la da también de masa y número de troncos por hectárea y clase diamétrica. En 6 perfiles fueron bosquejados los tipos principales forestales: en una franja de 5 m. de ancho se trazaron todos los árboles de 5 m. y más; en una segunda de igualmente 5 m., todos los de más de 10 m.; y en la tercera de 10 m. de ancho sólo los de 20 m. y más. En la lista de especies se da de todas las especies el nombre surinameño y el científico, y el número de ejemplares por perfil.

    Beschreibung: The peculiar distribution of the species of Rhizophora (Rhizophoraceae) is wellknown. Floras and manuals usually mention one western species — R. mangle L. — that occurs both in the coastal regions of tropical and subtropical America and in the corresponding habitats of west tropical Africa, and an eastern species — R. mucronata Lam. — occurring both in tropical Asia and in east tropical Africa. It is also well-known that a few other species occur in tropical Asia; a recent revision has been given by HOU (1958). G. F. W. MEYER (1818) described from British Guiana a second American species, R. racemosa, differing in the inflorescence which is forked and 2-flowered in R. mangle and much-branched in R. racemosa. ENGLER (1876) regarded this species as a variety of R. mangle; most botanists, however, considered it synonymous with the latter. LEECHMAN (1918) published an investigation of the Rhizophoras of Georgetown, British Guiana. He found not only the two species of Meyer but also a third species, R. harrisonii Leechm., provided with a much-branched inflorescence as in R. racemosa. The hypocotyls (also considered radicles) of both R. mangle and R. harrisonii reach a length of up to 30 cm, that of R. racemosa a length of up to 65 cm. The opinion of most botanists, however, remained unchanged: namely that the material of the genus Rhizophora from both America and West-Africa belongs to one species, R. mangle L. In treating the Rhizophoraceae for the Flora of Suriname I shared this opinion (JONKER, 1942). In 1953, however, KEAY published his revision of the West-African Rhizophoras based on field observations. He concluded that the three species recognized by Leechman also occurred in West-Africa. SAVORY (1953) studied the ecology of Rhizophora in Nigeria and found that the most common species is R. racemosa, a pioneer at the outer border of the Rhizophora zone. R. harrisonii is dominant in the middle region and R. mangle in the interior part of the zone. The latter has the highest salt tolerance and occurs in the habitats with the highest salt concentration in the dry season. The other species obtain, especially in the wet season, more fresh water.

    Beschreibung: On account of the reticulate spores with their large area of dehiscence and because of the structure of the pseudo-capillitium the monotypic genus Liceopsis and Enteridium splendens (syn. E. rozeanum) are returned to Reticularia. It is argued that R.? rozeana can not with certainty be identified, but that it can not be regarded as conspecific either with R. lobata or with R. splendens. Of R. lycoperdon a var. americana is separated, differing from the type by its free spores. A new species, R. intermedia, is described. It resembles R. lycoperdon in the dendroid pseudo-capillitium, but differs from the latter in the fragile cortex and in the filamentous structure of the pseudo-capillitium. It is known so far only from the vicinity of Doorwerth, province of Gelderland, the Netherlands.

    Beschreibung: Myrrhis odorata (L.) Scop. Te Leeuwarden aan een weg langs de spoorlijn. dicht bij Koopmans Meelfabrieken, trof ik, tussen planten van het fluitekruid, een groot exemplaar van Myrrhis odorata aan. Tuinen zijn niet in de buurt; het zal dus een exemplaar zijn, dat uit aangeveerd zaad is opgeslagen.

    Beschreibung: During his zoological collecting trips to the Antilles Dr. P. Wagenaar Hummelinck also gathered several samples of fresh and brackish water algae, which have been presented to the Rijksherbarium, Leiden. The present paper deals with the Chlorophyta of that collection, with the exception of Enteromorpha. Wagenaar Hummelinck’s localities 1936—1949 have been described in the “Studies on the Fauna of Curaçao”, Vols. 1 (1940), 2 (1940) and 4 (1953). Sta. 76 A has been illustrated in Vol. 1, Plate Vb; Sta. 97 in Vol. 2, Plate IV a; Sta. 500, 382, 63 and 678 in Vol. 4, Plates Ib, IIa, IIb and Va, respectively. The 1955 localities will be described in a “Third List of Localities”, to be published in a forthcoming volume of this series.

    Beschreibung: During 1957 two important collections of fishes were obtained from off the coast of Suriname and adjacent regions. The first of these was made by the motor vessel “Coquette”, a commercial shrimp trawler which engaged in exploratory work for the Government of Suriname. Mr. JAMES B. HIGMAN of the United States Fish and Wildlife Service was invited to accompany the “Coquette” during part of this work, and the collection of fishes which resulted was due largely to his efforts. The second collection was obtained by the motor vessel “Oregon”, exploratory vessel of the United States Fish and Wildlife Service. During November, 1957, the “Oregon” occupied over a hundred trawl stations along the northern coast of South America between Venezuela and the Equator. Most of these collections are now in the U. S. National Museum and the Chicago Natural History Museum. Both the “Oregon” and the “Coquette” collections contain representatives of a distinctive new species of Lonchopisthus. The definition of this species has required a review of the western Atlantic species of the genus. I take pleasure in naming this new species of Lonchopisthus from Suriname in honour of its collector:

    Beschreibung: In the earliest papers on neotropical Blattidae a fair number of specimens from Surinam were recorded (LINNAEUS, DE GEER ¹), DE SAUSSURE, BRUNNER). But in the period from the beginning of this century up to now only a few scattered reports of Blattidae from that region have appeared in the literature of the subject. The present article will be the first to deal exclusively with Surinam species. The material dealt with in this paper was mainly secured by DR. D. C. GEIJSKES between 1938 and 1955. His extensive travels both in the coastal area and far into the interior of Surinam enabled him to collect all over the country.

    Beschreibung: The present paper embodies the results of a study of 362 specimens of the genus Rivulus from Suriname and the other Guyanas. So far, 58 species names (morphological species or subspecies) have been proposed, by a great many authors; these names are listed on pages 52—53. Of the 58, topotypical specimens have been examined in 8 instances. In order to facilitate a future review of the genus, which is in great need of revision, short remarks are made on the morphology and ecology of a number of specimens, from various localities, belonging to distinct species.

The addition has proved to be justified after study of: 1. a collection of Tenebrionids gathered by Dr. H. J. MAC GILLAVRY, Professor of Geology at Amsterdam University, as a student member of an excursion that took place in 1930 under the direction of the late Prof. L. M. R. RUTTEN; 2. some additional material collected by Dr. P. WAGENAAR HUMMELINCK; 3. specimens from the collection of Ir. R. H. COBBEN, entomologist and agriculturist of Wageningen, in 1957; 4. material collected by B. DE JONG, biologist at Curaçao, and other sources.

    Beschreibung: J’ai récemment reçu du Dr. P. WAGENAAR HUMMELINCK de Utrecht environ 230 exemplaires (larves, nymphes et fourreaux vides) d’un Helicopsyche, recueillis par lui-même en 1936 en quelques localités de l’île de Margarita (Venezuela). Grâce au fait que les armatures génitales du ♂ et de la ♀ purent être trouvées chez une paire de nymphes, le problème de l’appartenance spécifique de cet insecte pût être élucidé; il s’agit d’une nouvelle espèce. Nous remercions vivement le Dr. P. WAGENAAR HUMMELINCK pour le matériel et pour les indications écologiques, ainsi que le Dr. D. E. KIMMINS du British Museum pour les précieuses indications qu'il nous a aimablement donné sur la forme que nous décrivons, après avoir consulté nos dessins.

    Beschreibung: A small area limited in the north by the Boca del Cantó, in the west by the Pallaresa river and in the south by the crest of the Montaña de Bahent and reaching westwards as far as the village of Feixa was surveyed in detail. Previous work by Prof. de Sitter and some of his pupils had revealed that in the steep southern slope of the Boca del Cantó several recumbent folds occur with Ordovician shales in the anticlinal cores and Devonian in the synclines. The work was carried out on the topographical base of an 1:25.000 enlargement of the official 1:50.000 map, sheets 214, Sort and 215 Seo de Urgel, which proved to be far from satisfactory. Aerial photographs were not available. The Tornafort area is limited in the north by an important fault, which runs practically in the bed of the Boca del Cantó. Tins fault forms the southern limit of the axial zone of the Pyrenees, north of it we find the Lower Triassic conglomerates, sandstones and shales covering unconformably strongly microfolded non metamorphic Ordovician. Near the mouth of the Boca del Cantó this clastic Trias is covered by the evaporite facies of the Keuper, with ophites and muschelkalk floats. The latter formation forms also the western boundary of our region on the lower slopes of the Tornafort hill towards the Pallaresa river, again separated from the Paleozoic by a north-cast trending fault. Thus the Tornafort area forms the northern border zone of the Nogueras zone as it has been defined by Peter Misch (1934). This Nogueras zone is known to have been strongly deformed by alpine orogeny because a little further south and west we see that the paleozoic has been folded together with the Triassic. A section by de Sitter (1957) crossing the Pallaresa river just west of our region shows a Devonian anticlinal core with Trias in the flanks. Our Tornafort region, however, is separated from the structure given by this section by a thrust along which the Devonian with Silurian at its base has been thrusted on the Triassie. This thrust forms the southwest boundary of our map, and the Tornafort structure does not seem to be connected with the just mentioned anticline, as has been done by de Sitter in his section, where the Tornafort structure is drawn as the core of a second anticline further south.

    Beschreibung: The results of an investigation of the structure and sedimentology of Upper Westphalian and Lower Stephanian strata in the eastern end of the Cantabrian palaeozoic core (NW Spain), are presented. The sediments, shales, sandstones, limestones and coal seams occur in three main associations: the orthoquartzite-carbonate, the turbidite and paralic associations. Two facies are dstinguished: a western, without turbidites, with relatively many coal seams and an eastern, with turbidites and a few coal seams. Some evidence for a zone of less subsidence is present. This zone separates the two facies. The western and eastern facies are represented by the rocks in the Sierra Corisa and Redondo synclines respectively. Between the two synclines occurs a zone of long stretched narrow folds, often upthrusted to the west. Fold axes generally plunge SSE. Some of the structural features are explained by disharmonic folding and extrusion tectonics. In the eastern facies a formation occurs, which consists of graded sandstones alternating with mudstones. Thickness measurements of the individual sandstone and mudstone beds are analysed with non-parametric statistical methods. Several regularities in the succession of lithological types or thicknesses are revealed. Correlations between thickness or position of variates (i. e. sandstone, mudstone, sideritic concretion) are tentatively explained in the light of the turbidity current hypothesis. Especially the successive sandstone thicknesses show an interdependence expressed in “fluctuations”. Sandstone-mudstone thickness-correlation leads to the assumption of a very high mud content of the turbidity current in these cases, and considerable erosion by successive currents. Sedimentary structures, especially those of the turbidite association, are described in detail. A short annotated bibliography on sole markings is given. The palaeocurrent directions measured from sole markings and cross-bedding are discussed. The sequence of sole-marking-directions on successive turbidite layers indicates interdependence of these dirctions, which could also mean the interdependence of the depositing currents. A litho-stratigraphic map, three structural sections and twelve stratigraphic sections are given.

    Beschreibung: In der Höhle Reichentalloch bei Hirschbach fand sich eine Fauna mit 33 Arten, darunter Anuren bis 38%. Die Fauna konnte in einen frühpostglazialen Auftauabschnitt gestellt werden. Auch konnte innerhalb derselben auf eine Durchwanderung von Pitymys subterraneus hingewiesen werden. Es wurde ein Diagramm-Auszug angefügt, entnommen einem großen Faunen-Diagramm, das aus den bisher in dieser Folge bearbeiteten, prozentual berechneten, ungestörten 30 Fundstellen mit 120 Schichten zusammengestellt worden ist, um die seltenen, aber auffälligen Anuren-Anhäufungen, daselbst eingereiht, als Auftauperioden zu erkennen, wie sie jeder Kältezeit folgten. Auch wurde eine Durchwanderungszeit von Microtus gregalis, der sibirischen Zwiebelmaus, aufgezeichnet; vermutlich auf der Flucht vor der einsetzenden Warmzeit.

    Beschreibung: In an adult female of the common eel Anguilla anguilla a large lipoma was found, situated on the left side, caudally of the left operculum. Microscopically, the tumour, which originated from the subcutaneous connective tissue, was composed of areas of adipose tissue and areas of fibrous connective tissue.\nThe tumour belongs to the fibrolipomatous type and shows a striking resemblance with the lipoma, described by Stolk (in press) in the lizard Lacerta muralis.

    Beschreibung: Twenty-one species of Distichopora have been described after specimens from various localities in the Indo-Pacific region, viz., D. violacea (Pallas, 1766) from \xe2\x80\x9cMare Indicum\xe2\x80\x9d, D. cinnabarina Nardo, 1844, from the Red Sea (?), D. gracilis Dana, 1848, from the Tuamotu Islands, D. coccinea Gray, 1860, from New Caledonia, D. fulvacea Michelin, 1862, from R\xc3\xa9union, D. nitida Verrill, 1864, from the Marshall Islands, D. rosea Kent, 1871, from the East coast of Australia, D. purpurea Schmeltz, 1875 (nomen nudum), from the Marshall Islands (?), D. irregularis Moseley, 1879, from the Philippine Islands, D. livida Tenison-Woods, 1879, from the Solomon Islands, D. brasseyi Wright, 1882, from the Gilbert Islands, D. allnutti Wright, 1882, from the Gilbert Islands (?), D. breviserialis Quelch, 1884, from unknown locality, D. milesii Quelch, 1884, from the Pacific (probably from the region of the Society and Tuamotu Islands), D. granulosa Quelch, 1885, from Rarotonga (?), D. conferta Quelch, 1885, from Rarotonga, D. ochracea Quelch, 1885, from the Solomon Islands, D. profunda Hickson & England, 1909, from the Chagos Archipelago, D. borealis Fisher, 1938, from the Aleutian Islands, D. fisheri Broch, 1942, from the Fiji Islands, and D. serpens Broch, 1942, from the Philippine Islands. Most of the described species came from shallow water, only three species were collected from great depths, viz., D. profunda (187\xe2\x80\x94274 m), D. borealis (518\xe2\x80\x94881 m), and D. serpens (91\xe2\x80\x94183 m). The type specimen of D. irregularis came from a depth of 10 fathoms (18 m).\nTo the species enumerated above should be added D. providentiae (Hickson & England, 1909) from off Providence Island in the Western Indian Ocean, collected at a depth of 125 fathoms (228 m). This species was originally placed in the genus Sporadopora, but the manner of arrangement of the gastropores and the dactylopores indicate that it presents at least some affinity to the genus Distichopora, and accordingly it may provisionally find a place here.

    Beschreibung: The main purpose of this study is to search for an explanation of the curious differentiation within the genus Chamaeleo. Since the species of this genus are rather doubtful units, I have studied the geograpical distribution of characters, not of the species, a method first used in botany (BAUR, ROTHMALER a.o.). I found that the number of characters is largest in east Afrika, gradually decreasing from this area to the periphery of the total range of the genus. East Africa proved to be still more important, as practically all the characters occur in it. This means that the chameleons in the other areas practically never possess characters that are not found in east Africa.\nThis pattern of distribution fits in rather well with REINIG\xe2\x80\x99S elimination theory (1938): \xe2\x80\x9e.. bei Einzelwanderungen wird nur ein Teil des gesamten Allelbestandes einer Art mitgef\xc3\xbchrt... eine durch Einzelwanderung entstandene Population weist eine geringere Zahl von Allelen auf als die Ausgangspopulation.\xe2\x80\x9d The existence of many parallel series of variation (meaning that several characters originated several times independently in different groups) led me to the conclusion that the mechanism described in REINIG\xe2\x80\x99S theory as elimination, has consequences also for the genes predisposed to change into others.\nThis reasoning gave a key to the reconstruction of the ancestral chameleon. By two different ways I arrived at the same conclusion, viz. the ancestral chameleon was probably an animal resembling mostly Chamaeleo chamaeleon s.l. (\xc2\xa7 21).\nAs for this theoretical part of my study a survey of the species was needed, I first made an attempt at a natural system. I have divided the genus into groups of related species. For practical reasons the chameleons of Madagascar are treated separately. Their connections with the species of the African continent are examined in a special section (\xc2\xa7 11).\nAs a result of my investigations I had to propose the following taxonomic changes: Ch. rhinoceratus var. lineatus + Ch. labordi + Ch. voeltzkowi + Ch. barbouri = Ch. rhinoceratus (\xc2\xa7 3), Ch. lambertoni = Ch. lateralis (\xc2\xa7 4), Ch. semicristatus = \xe2\x99\x80 Ch. verrucosus (\xc2\xa7 5), Ch. guibei nov. spec. (\xc2\xa7 6), Ch. calcarifer = Ch. chamaeleon calcarifer, Ch. zeylanicus = Ch. chamaeleon zeylanicus, Ch. etiennei = Ch. gracilis etiennei (\xc2\xa7 12), Ch. anchietae vinkei + Ch. anchietae mertensi + Ch. marunguensis = Ch. anchietae (\xc2\xa7 13), Ch. unicornis = Ch. oweni unicornis (\xc2\xa7 14), Ch. pumilus = Ch. pumilus pumilus, Ch. melanocephalus = Ch. pumilus melanocephalus, Ch. gutturalis = Ch. pumilus gutturalis, Ch. ventralis = Ch. pumilus ventralis, Ch. ventralis occidentalis = Ch. pumilus occidentalis, Ch. ventralis karrooicus = Ch. pumilus karrooicus, Ch. damaranus = Ch. pumilus damaranus, Ch. caffer = Ch. pumilus caffer, Ch. taeniobronchus = Ch. pumilus taeniobronchus. (\xc2\xa7 16).

    Beschreibung: The present short paper forms a continuation of my partial revision of certain species of the genus Bactra (Zool. Verhand., no. 29, 1956). It is chiefly based on a revision of the entire material of Bactra in the collection of the well-known specialist of Microlepidoptera, Dr. H. G. AMSEL, Karlsruhe, Germany; along with the new material of the genus from Irak, and that from Afghanistan, of the German Afghanistan Expedition 1956, collected by Dr. AMSEL himself and entrusted to me for identification. Besides, interesting material was received from Mr. TOSHIIO OKU, Sapporo, Japan, and from some other sources. The author gratefully acknowledges the kind help of the senders, and their permission to retain certain duplicates for the collection of the Leiden Museum.\nSince the publication of my above mentioned paper a few errors were detected and some alterations became necessary. They will be found below, together with descriptions of five new species and one subspecies, and records or notes on some 15 already known species, with five new synonyms.

    Beschreibung: A review is given of the recurrent outbreaks of the tentcaterpillar, Malacosoma neustria L., affecting the elm trees in the city of Amsterdam in the period 1930\xe2\x80\x941957. An outbreak of the brown tail moth, Euproctis chrysorrhoea L., in 1935\xe2\x80\x941936 is also mentioned and some occasional loss of foliage through the caterpillars of the vapourer moth, Orgyia antiqua L.\nLarge fluctuations in the size of the Malacosoma populations were found. After some years in which the damage was negligeable, the increase always started in the N.W. part of the centre of the city. In the following years the outbreaks moved to adjacent parts of the centre and finally sometimes even to more eccentric parts (see Fig. 6\xe2\x80\x949). However, the occurrence of really harmful numbers of tentcaterpillars was mostly restricted to the centre of the town.\nThe merits of the control measures which were carried out with derris/talcum powder spread by motordusters are discussed. The insecticide was thought to be the only sufficiently harmless for its use in the centre of a city. Some cases of defoliation and other inconveniences caused by the presence of crowds of caterpillars could apparently be reduced by the control measures. In several instances, however, the efficacy of the method remained doubtful.\nThe urgency is stressed of further studies of the bionomics of Malacosoma under local conditions and some suggestions are made for a better organization of the measures applied.

    Beschreibung: In most handbooks on forest entomology much stress is laid on the importance of predatory arthropods in the soil as enemies for pupating noxious insects (ESCHERICH, 1923; GRAHAM, 1939). However, detailed investigations in the field on the significance of these predators are scarce.\nIn Germany much work has been done on the biology and feeding habits of Carabus species (KERN, 1921; LENGERKEN, 1921; OERTEL, 1924; DELKESKAMP, 1930; KIRCHENER, 1927; JUNG, 1940) but these observations and experiments were mainly done under laboratory conditions. FORBES (1880, 1882) investigated the gut contents of many carabid species and concluded that about 1/3\xe2\x80\x941/4 of the food was of animal origin. VIT\xc3\x89 (1953) studied the significance of spiders in forests.

    Beschreibung: A description is given of the activity of the thyroid and of the pituitary gland during the development of the gonopodium in the viviparous Cyprinodonts Lebistes reticulatus (Peters), Xiphophorus helleri (Heckel) and Xiphophorus maculatus (G\xc3\xbcnther). During this process the thyroid gland and the glandular lobe (lobus anterior and lobus intermedius) show a gradual increase in activity. This activity was in general most pronounced in Lebistes reticulatus (Peters) and weakest in Xiphophorus maculatus (G\xc3\xbcnther). This increase in activity suggests that the developement of the gonopodium is probably regulated endocrinally.\nFor the determination of the state of thyroid and pituitary activity use was made of the quotients d/n and D/n (Lever, 1948 and 1950; cf. Lever, Miltenburg and Van Oordt, 1949, and Stolk, 1951 c, 1956 g, 1957 b and 1958 b) and the quotients ch and cs (Stolk, 1954, 1955 a, 1956 a, 1956 c, 1956 d, 1956 e, 1956 f, 1957 a, 1958 a and 1958 b), respectively, and moreover of the nucleus size, the mitotic activity, the nucleus structure, the chondriome and the Golgi apparatus.

    Beschreibung: The systematic position of the western hamster, Cricetus cricetus canescens, has been a subject of discussion and criticism ever since NEHRING (1899, pp. 1\xe2\x80\x942) described the hamster occurring in Belgium west of the Meuse as a separate variety. The present paper is a new effort to throw more light on the interesting question concerning the systematic characters by which the western hamster can be distinguished from the typical form described from central Germany. For a better understanding of the present study a brief survey of the main points in the historical development of this problem follows here.\nAccording to NEHRING the main characters in which his new variety, Cricetus vulgaris var. canescens, differed from the typical form, were: (1) the dark mouse-greyish colour of the dorsal surface, (2) the less intensive black colour of the ventral surface, (3) the smaller size, and (4) the presumably larger ears. It is to be noted, however, that NEHRING based his description merely on two stuffed skins from the neighbourhood of Fexhe-Slins, Belgium, which he compared with specimens from Saxony and Brandenburg.

    Beschreibung: Am 5. August 1956 traf von Dr. H. Kern auf dem Schiffswege aus Djakarta eine erwachsene Netzschlange, Python reticulatus Schn., von 6.40 m L\xc3\xa4nge im Tierpark Berlin ein. In ihre Kiste hatte man f\xc3\xbcr den etwa vier Wochen dauernden Schiffstransport ein lebendes Huhn (gro\xc3\x9fer Malaiischer K\xc3\xa4mpfer) hineingesetzt, das unterwegs gefressen wurde. Reste davon \xe2\x80\x94 darunter ein Fu\xc3\x9f \xe2\x80\x94 wurden dann unvollkommen verdaut wieder erbrochen. Nach der Ankunft in Berlin brachten wir die Riesenschlange zun\xc3\xa4chst provisorisch in einem kleinen Terrarium unter. Dort nahm sie zwei mittelgro\xc3\x9fe Meerschweinchen zu sich. Mittlerweile war ein gr\xc3\xb6\xc3\x9ferer Beh\xc3\xa4lter f\xc3\xbcr das Tier fertiggestellt worden, in den die inzwischen durch die W\xc3\xa4rme der Schlangenfarm munterer gewordene Schlange umgesetzt wurde. Hier verweigerte die Schlange in der Folge jede weitere Nahrung. Es zeigte sich nunmehr \xe2\x80\x94 4 m distal von der Schnauzenspitze \xe2\x80\x94 eine abgetreppte Verschiebung (Abb. 1) der Wirbels\xc3\xa4ule, die auf einen Bruch des R\xc3\xbcckgrates schlie\xc3\x9fen lie\xc3\x9f. Die Schlange magerte in den folgenden Wochen erheblich ab, und der Bruch trat endlich so stark in Erscheinung, da\xc3\x9f der Python nicht mehr ausgestellt werden konnte. W\xc3\xa4hrend die Schlange in der ersten Zeit noch sehr aggressiv war und der vor dem Bruch liegende K\xc3\xb6rperteil immer noch hoch aufgerichtet wurde, ergriff in zunehmendem Ma\xc3\x9fe immer gr\xc3\xb6\xc3\x9fere Apathie das Tier, bis es schlie\xc3\x9flich v\xc3\xb6llig teilnahmslos herumlag. Innerhalb von vier Monaten erfolgten drei H\xc3\xa4utungen. Hinter dem Bruch schwoll der v\xc3\xb6llig gel\xc3\xa4hmte K\xc3\xb6rperabschnitt bis zum After stark an (Abb. 2). Der Schwanz blieb von der Schwellung unber\xc3\xbchrt. Der K\xc3\xb6rperumfang vor dem Bruch betrug 35 cm, hinter ihm 56 cm. Die Haut des aufgetriebenen K\xc3\xb6rperteiles war sehr m\xc3\xbcrbe und n\xc3\xa4\xc3\x9fte an verschiedenen Stellen. Am 30. November 1956 starb die Netzschlange. Der angeschwollene Teil ging nach dem Tode der Schlange sofort in F\xc3\xa4ulnis \xc3\xbcber. Im Enddarm fand sich eine riesige Menge von Harns\xc3\xa4urekristallen gespeichert, obwohl w\xc3\xa4hrend der Krankheit des Tieres wiederholt gro\xc3\x9fe Portionen von Kot manuell aus der Kloake geholt worden waren.\nDr. G. BEUTEL (Berlin-Lichtenberg) \xc3\xbcbernahm freundlicherweise das R\xc3\xb6ntgen und die entsprechende Deutung. Es stellte sich \xe2\x80\x94 wie vermutet \xe2\x80\x94 tats\xc3\xa4chlich ein Wirbels\xc3\xa4ulenbruch heraus. Der betreffende Wirbel ist stark destruiert. Hier macht die Wirbels\xc3\xa4ule einen nach rechts gerichteten Knick (Abb. 4), und beim Seitenbild erkennt man au\xc3\x9ferdem eine Versetzung der beiden Wirbels\xc3\xa4ulenabschnitte in dorsoventraler Richtung um fast die volle Wirbels\xc3\xa4ulendicke (Abb. 5). Wolkige Schattenbildungen an diesem Abschnitt d\xc3\xbcrften Callus sein. Auf der Seitenaufnahme sieht man weiterhin multiple alte und frische Rippenfrakturen, von denen die letzteren durch kr\xc3\xa4ftigen Callus bereits \xc3\xbcberbr\xc3\xbcckt werden. In H\xc3\xb6he des destruierten Wirbels sind links mehrere Rippen zu sehen, die z.T. etwas aufgetrieben sind und zentrale Aufhellungen mit exzentrischer Verd\xc3\xbcnnung der Compacta aufweisen. Hierbei d\xc3\xbcrfte es sich um Enchondrome handeln. Soweit die Tatsachen und die Befunde.

    Beschreibung: In 1734 verscheen te Amsterdam het eerste deel van het klassiek geworden werk van Albertus Seba : Locupletissimi rerum naturalium Thesauri accurata descriptio, et iconibus artificiosissimis expressio, per universam physices historiam. In dit werk, vaak aangeduid alleen met de naam \xe2\x80\x9eThesaurus", geeft Seba naast voor die tijd goede beschrijvingen prachtige gekleurde afbeeldingen van de behandelde voorwerpen. Tot de \xe2\x80\x9erijkste schatten" van het dierenrijk rekent Seba ook twee kleurafwijkingen van de mol, Talpa europaea L., waarvan de eerste op pagina 51 wordt vermeld als: Talpa, alba, nostras [de witte mol van ons Vaderland]. De op plaat xxxii fig. 1 gegeven afbeelding van deze kleurvariant toont echter een mol met een licht roomkleurige tint.\nUit de omgeving van zijn geboorteplaats Etzela, Oost-Friesland, kende Seba een mol met witte onregelmatige vlekken (p. 68; pl. xli fig. 4). Deze kleurvari\xc3\xabteit wordt door hem genoemd: Talpa, maculata, Oost-Frisia [de gevlekte mol van Oost-Friesland].\nNaar beide afbeeldingen van Seba wordt door Houttuyn (1761, p. 310) verwezen in het 2de stuk van het eerste deel van zijn uitvoerige bewerking van \xe2\x80\x9eSystema naturae" van Linnaeus : \xe2\x80\x9eBehalve de gewoone Mol, die zwartagtig is, wordt somtyds, in ons Land, ook een witte gevonden, by Seba afgebeeld, en eene, die Klein de Oostfriesche noemt, zynde een weinig grooter, en over \'t geheele Lyf als gemarmeld met witte Vlakken op een zwarten Grond." Hierbij dient opgemerkt te worden dat Klein (1751, p. 60) onder de Oostfriesche mol de Talpa maculata van Seba verstaat. In 1776 heeft Houttuyn de gelegenheid lezers, die met het Nederlands vertrouwd zijn, op een derde kleurverscheidenheid van de mol te wijzen en wel in de vertaling van het Engelse werk van Edwards & Catesby : \xe2\x80\x9eVerzameling van uit-

    Beschreibung: The peculiar distribution of the species of Rhizophora (Rhizophoraceae) is wellknown. Floras and manuals usually mention one western species \xe2\x80\x94 R. mangle L. \xe2\x80\x94 that occurs both in the coastal regions of tropical and subtropical America and in the corresponding habitats of west tropical Africa, and an eastern species \xe2\x80\x94 R. mucronata Lam. \xe2\x80\x94 occurring both in tropical Asia and in east tropical Africa. It is also well-known that a few other species occur in tropical Asia; a recent revision has been given by HOU (1958). G. F. W. MEYER (1818) described from British Guiana a second American species, R. racemosa, differing in the inflorescence which is forked and 2-flowered in R. mangle and much-branched in R. racemosa. ENGLER (1876) regarded this species as a variety of R. mangle; most botanists, however, considered it synonymous with the latter. LEECHMAN (1918) published an investigation of the Rhizophoras of Georgetown, British Guiana. He found not only the two species of Meyer but also a third species, R. harrisonii Leechm., provided with a much-branched inflorescence as in R. racemosa. The hypocotyls (also considered radicles) of both R. mangle and R. harrisonii reach a length of up to 30 cm, that of R. racemosa a length of up to 65 cm. The opinion of most botanists, however, remained unchanged: namely that the material of the genus Rhizophora from both America and West-Africa belongs to one species, R. mangle L. In treating the Rhizophoraceae for the Flora of Suriname I shared this opinion (JONKER, 1942).\nIn 1953, however, KEAY published his revision of the West-African Rhizophoras based on field observations. He concluded that the three species recognized by Leechman also occurred in West-Africa. SAVORY (1953) studied the ecology of Rhizophora in Nigeria and found that the most common species is R. racemosa, a pioneer at the outer border of the Rhizophora zone. R. harrisonii is dominant in the middle region and R. mangle in the interior part of the zone. The latter has the highest salt tolerance and occurs in the habitats with the highest salt concentration in the dry season. The other species obtain, especially in the wet season, more fresh water.

    Beschreibung: In 1935 the present author reported the occurrence of this N. American species in the eastern part of Holland, province of Overijssel, in the vicinity of Almelo (JONKER, 1935). He found the species near the hamlet of Harbrinkhoek on a wet heath. The locality was also the only station of Wahlenbergia hederacea in the Netherlands, discovered a year before. Notwithstanding the extensive reclamations in that part of the country the species now still occurs in a number of localities around Almelo. The plants cannot be considered adventitious as they were found in places that are comparatively little influenced by human culture, judging from the occurrence, on the first-discovered locality, of e.g. Wahlenbergia hederacea. Gentiana pneumonanthe, Viola palustris, Radiola linoides, Linum catharticum, Scutellaria minor. The late Dr. Wachter discovered, in the herbarium of the Royal Botanical Society of the Netherlands, unidentified specimens of Hypericum canadense collected by Lako as early as 1909 in the same environment, perhaps even in the same station; and Dr. van Soest identified two specimens collected in 1918 by the late naturalist Bernink near Denekamp, about 20 km E of the above mentioned localities.\nBouchard (1953, 1954, 1955) reported the discovery of the species in France, dept. Haute-Sa\xc3\xb4ne. The plants were found in large quantities, at the stony beach of oligotrophous lakes, together with Littorella uniflora. In his detailed publication of 1954 he discussed the possibilities of introduction. He concluded that the plants are not adventitious. They may be autochthonous or naturalized and then, when the latter is the fact, probably by U.S. army units that stayed in that area during world war I. He did not preclude, however, the possibility of a glacial relic. Bouchard overlooked the previous publication reporting the occurrence in Holland.

    Beschreibung: When studying the Gesneriaceae of Guiana (1958) the present author saw a fairly considerable number of misidentified and unnamed specimens some of which proved to belong to undescribed species. Several of the latter are described below. Besides, several of the species he met with, had to be transferred to other genera. New combinations, however, were made only in those cases where the author could examine the type.

    Beschreibung: Since the last Bulletin was published our circle of collaborators has unfortunately lost Dr A.H.G. Alston, who had agreed to join Prof. Holttum in editorship of the Fern volumes of the Flora. It is an irreparable loss to pteridology as Dr Alston had an unparalleled, detailed knowledge and has unfortunately postponed the publication of a large amount of his findings and conclusions, which are now lost or doomed to remain unavailable in hardly legible written and uncorrected notes. I hope that it will be found possible to edit his interpretation of the Hortus Malabaricus of which he possessed a card index which obviously dated from his Ceylon time.\nAnother sad loss is the recent passing away of the wellknown cyperologist of Kew, Mr E. Nelmes, who has done a great service to the Flora Malesiana by his work on the genus Carex.

Stipes of Cyathea containing numerous small vascular strands arranged in 3 series (fig. 6), these strands more or less united in smaller axes of Cyatheafronds and also in larger axes of other genera (fig. 31f, 33d); stipe-bases persistent, or sooner or later caducous leaving a pattern of scars on the caudex; pneumathodes present along each side of stipe, in a single discontinuous or almost continuous row, or in 2\xe2\x80\x943 rows close together, the row joining upwards to a similar row on the basiscopic side of the first pinna, a \xc2\xb1 circular pneumathode at the base of the pinna beginning the row on the main rachis to the next pinna. Dermal appendages on fronds: multiseptate hairs only, or both hairs and scales (Cyathea); if both, the hairs often confined to the adaxial surface of the fronds. Fronds in most cases bipinnate-tripinnatifid, with varying gradations to tripinnate, in a few cases simply pinnate, in Culcita 3\xe2\x80\x944-pinnate; pinnules almost symmetrical at the base except in Culcita; veins normally free except in Cyathea capitata and in the genus Cnemidaria (trop. America).

Throughout the wetter parts of the tropics, especially on mountains; a few species just north of the tropics, more south of the tropics especially in Australasia. As here construed, 9 genera, of which 5 are Malaysian: Cyathea (pantropic, at least 600 spp.); Cnemidaria (limited to species with pinnate fronds, anastomosing veins and distinctive spores, tropical America, 10 spp.); Lophosoria (tropical America, monotypic); Dicksonia (tropics and southern subtropics in Malaysia, Australasia, America, St Helena, c. 25 spp.); Cystodium (Malaysia, monotypic); Thyrsopteris (Juan Fernandez, monotypic); Culcita (subg. Culcita in Azores and tropical America; subg. Calochlaena in Malaysia and Australasia; in all c. 7 spp.); Cibotium (SE. Asia, Malaysia, Hawaii, Central America, c. 12 spp.); Metaxya (tropical S. America, monotypic).

A few scattered notes exist which deal with the crabs and shrimps of the region, but no comprehensive account of the Decapoda of any of the three countries has ever been published apart from Young\'s (1900) "The stalk-eyed Crustacea of British Guiana, West Indies and Bermuda", which, however, also covers the West Indian Islands and Bermuda (including the deep-water species), and furthermore is incomplete.

    Beschreibung: The well-known Ray Society undertook the publication of this new facsimile of Linnaeus\xe2\x80\x99s most famous and still indispensable botanical work and had it reproduced photographically from an original copy in Linnaeus\xe2\x80\x99s library, later owned by Sir James Edward Smith. It represents the third facsimile edition of the work and, in spite of the earlier Berlin (1907) and Tokyo (1934) editions, which are no longer obtainable, it will certainly fill a real need, were it only to save copies of the rare and expensive original from wear and tear.\nAlthough much has been written about Linnaeus and his numerous publications, the delightful frame provided by W. T. Stearn and J. L. Heller makes the new edition all the more valuable and useful, not only since the supplementary chapters enliven the book as a cultural product of its period but because the introduction and much of the appendix have been very ably written by a working taxonomist primarily concerned with Linnaeus\xe2\x80\x99s works for their relevance to modern botanical nomenclature, who has thoroughly studied history, method and bibliography and also, to some extent, the life and psychology of the author and the scientific attitudes of the period. Stearn has also aimed at avoidance of the misunderstanding and confusion, which follow from treating 18th century publications as if they were 20th century productions. Emphasis is laid on what may well be the most important conclusion for Linnaean typification in the whole work (cf. p. 97), viz. that within every main entry in Species Plantarum there is, or was at some stage of its development, an illustration or a specimen seen by Linnaeus and not simply a description by a pre-Linnaean author, the exceptions being definitions or descriptions by Van Boyen, Gronovius, or Boissier de Sauvages, his disciples, so to speak, in the Linnaean method, whose work was therefore acceptable.
