    In:  Supplement to: Andrews, Anthony J (1979): On the effect of low-temperature seawater-basalt interaction on the distribution of sulfur in oceanic crust, layer 2. Earth and Planetary Science Letters, 46(1), 68-80, https://doi.org/10.1016/0012-821X(79)90066-9
    Publication Date: 2024-05-15
    Description: A detailed geochemical-petrological examination of layer 2 basalts recovered during Leg 37 of the DSDP has revealed that the original distribution, form and abundance of igneous sulfide have been profoundly altered during low-grade oxidative diagenesis. The net result appears to have been a rather pervasive remobilization of igneous sulfide to form secondary pyrite accompanied by a bulk loss of sulfur equivalent to about 50-60% of the original igneous value, assuming initial saturation. It is suggested that during infiltration of seawater into the massive crystalline rock, igneous sulfide has experienced pervasive oxidation, under conditions of limited oxidation potential, to form a series of unstable, soluble sulfur species, primarily in the form of SO3[2-] and S2O3[2-]. Spontaneous decomposition of these intermediate compounds through disproportionation has resulted in partial reconstitution of the sulfur as secondary pyrite and the generation of SO4[2-] ion, which, due to its kinetic stability, has been lost from the basalt system and ultimately transferred to the ocean. This model not only satisfies the geochemical and petrological observations but also provides a suitable explanation for the highly variable delta34S values which characterize secondary sulfides in deep ocean floor basalts.

    Description: Titanomagnetites separated from 15 different rock samples (including ocean-floor basalts from DSDP Legs 37, 45 and 46) were analyzed together with whole-rock samples by instrumental neutron-activation analysis for Sc, Cr, Co, Zn, Hf, Ta, Th and the REE La, Ce, Nd, Sm, Eu, Gd, Tb, Dy, Tm, Yb and Lu. In titanomagnetities from ocean-floor basalts and some other rocks, REE are enriched with respect to the whole-rock composition by factors of between 1.5 and 3 for light REE and between 1.0 and 1.9 for heavy REE; that is, REE with larger ionic radii are preferentially incorporated into the magnetite lattice. Three magnetite samples are REE depleted. Their whole-rock samples contain P in appreciable amounts, so apatite, an important REE-accumulating mineral, could have captured REE to some extent. All titanomagnetites show a marked negative Eu anomaly, this is most probably caused by discrimination of Eu(2+) from the magnetite lattice. Co, Zn, Hf and Ta are significantly enriched in magnetites. The distribution behaviour of Sc and Cr is masked chiefly by the crystallization of clinopyroxene and therefore is not easy to estimate. Ulvöspinel contents of about 70% for the titanomagnetites from ocean-floor basalts were estimated from qualitative microprobe analysis. Ulvöspinel contents of all other samples varied in a wide range from 20% to about 90%. No correlation could be observed between this and the REE contents of the magnetites. Ilmenite exsolution lamellae could only be observed in titanomagnetites from a doleritic basalt from Leg 45.

    In:  Supplement to: Müller, Peter J; Suess, Erwin (1979): Productivity, sedimentation rate, and sedimentary organic matter in the oceans. I.- Organic matter preservation. Deep-Sea Research Part A. Oceanographic Research Papers, 26(12), 1347-1362, https://doi.org/10.1016/0198-0149(79)90003-7
    Publication Date: 2024-05-15
    Description: Comparison of rates of accumulation of organic carbon in surface marine sediments from the central North Pacific, the continental margins off northwest Africa, northwest and southwest America, the Argentine Basin, and the western Baltic Sea with primary production rates suggests that the fraction of primary produced organic carbon preserved in the sediments is universally related to the bulk sedimentation rate. Accordingly, less than 0.01% of the primary production becomes fossilized in slowly accumulating pelagic sediments [(2 to 6 mm (1000 y)**-1] of the Central Pacific, 0.1 to 2% in moderately rapidly accumulating [2 to 13 cm (1000 y)**-1] hemipelagic sediments off northwest Africa, northwest America (Oregon) and southeast America (Argentina), and 11 to 18% in rapidly accumulating [66 to 140 cm (1000 y)**-1] hemipelagic sediments off southwest America (Peru) and in the Baltic Sea. The emiprical expression: %Org-C = (0.0030*R*S**0.30)/(ps(1-Theta)) implies that the sedimentary organic carbon content (% Org-C) doubles with each 10-fold increase in sedimentation rate (S), assuming that other factors remain constant; i.e., primary production (R), porosity and sediment density (ps). This expression also predicts the sedimentary organic carbon content from the primary production rate, sedimentation rate, dry density of solids, and their porosity; it may be used to estimate paleoproductivity as well. Applying this relationship to a sediment core from the continental rise off northwest Africa (Spanish Sahara) suggests that productivity there during interglacial oxygen isotope stages 1 and 5 was about the same as today but was higher by a factor of 2 to 3 during glacial stages 2, 3, and 6.

    Publication Date: 2024-05-15
    Description: Oceanic crustal drilling by R. V. Glomar Challenger at 15 sites in the North Atlantic has led to a complex picture of the upper half kilometer of the crust. Elements of the picture include the absence of the source for linear magnetic anomalies, marked episodicity of volcanic activity, ubiquitous low temperature alteration and evidence for large scale tectonic disturbance. Comparison sections in the Pacific and much deeper crustal drilling are needed to attack problems arising from the North Atlantic results.

    Publication Date: 2024-04-16
    Description: The continental slope and rise, east of Newfoundland, accommodates two distinct gravel populations. The upper slope (300-700 m depth) population is characterized by unstained, granules to boulders of predominantly granitic and terrigenous sedimentary compositon that show affinity to Paleozoic and Proterozoic rocks of Newfoundland and areas further north. The rise (2,500-〉3,000 m depth) population consists of iron- and ferromanganese-stained granules to cobbles composed mainly of carbonate that presumably has been derived from the high Canadian Arctic. The rise clasts are further distinguished in that they are finer grained, slightly more rounded and more altered by solution and/or boring organisms than their shallower water counterparts. The upper slope gravel has been reworked from underlying sediments, and deposited from ice rafts, and both processes are probably continuing today. Gravel on the rise has been concentrated through winnowing of middle Holocene sediments by the Western Boundary Undercurrent which appears to have been operative as a winnowing agent since about 4,000 to 5,000 y BP. The undercurrent has also affected the distribution of stained gravel which is most common and most intensely stained beneath a fast-flowing undercurrent core where environmental conditions resemble those documented for deep-sea, ferromanganese nodule fields.

    Description: Mineralogical analysis of manganese nodules and crusts collected from Indian ocean aboard Marion Dufresne points to a depth and regional control upon the manganese oxide association: vernadite - birnessite and vernadite - todorokite. Moreover, progressive changes in the vernadite/birnessite ratio as a function of time is clearly seen. Magnetite and titano-magnetite in quantities similar to those of framboidal pyrite in manganese nodules are outlined for the first time. Study of the distribution of metals (Mn, Fe, Ni, Cu, Co) shows a strong latitudinal and regional dependence that may be connected to high productivity zones and to bottom water properties. The problem of mineralogical control on the chemical composition is approached. Finally, it results that any interpretations taking into account all these data haveway to give to the variability of sea-water properties (pH, oxygenation, motions) the prominent control upon manganese nodules composition.

    In:  Supplement to: Diester-Haass, Lieselotte; Müller, Peter J (1979): Processes influencing sand fraction composition and organic matter content in surface sediments off W Africa (12-19°N). Meteor Forschungsergebnisse, Deutsche Forschungsgemeinschaft, Reihe C Geologie und Geophysik, Gebrüder Bornträger, Berlin, Stuttgart, C31, 21-48
    Publication Date: 2024-02-03
    Description: Surface sediments from 5 profiles between 30 and 3000 m water depth off W Africa (12-19° N) have been studied for their sand fraction composition and their total calcium carbonate and organic matter contents to evaluate the effect of climatic and hydrographic factors on actual sedimentation. On the shelf and upper slope (〈 500 m), currents prevent the deposition of significant amounts of fine-grained material. The sediments forming here are characterized by high sand contents (〉 60 %; in most samples 〉 89 %), low organic carbon contents (in most samples 〈 0.8 %), high median diameters of the sand fraction (120-500 µm), and by a predominance of quartz and biogenic relict shells (most abundant: molluscs and bryozoans) in the sand fraction. Median diameters of total sand fraction and of major biogenic sand fraction components (biogenic relict material, benthonic molluscs, benthonic and planktonic foraminifers) co-vary to some extent and show maximum values in 100-300 m water depth, reflectingthe sorting effect of currents (perhaps the northward flowing undercurrent). In this water depth, biogenic relict material is considerably enriched relative to wuartz, the second dominating sand fraction component on the shelf and upper slope, resulting in distinct calcium carbonate maxima of the bulk sediments. The influence of the undercurrent is also reflected in a northward transport of fine grained river load and perhaps in the distribution of the red stained, coarse silt and sand-size clay aggregates, which show maxima in 300-500 m water depth. They probably originate from tropical soils. Abundant coarse red-stained quartz on the shelf off Cape Roxo (12-130° N) suggests a southward extension of last glacial dune fields to this latitude. Below about 500 m water depth, current influence becomes negligible – as indicated by a strong decrease in sand content, a concomitant increase in sedimentary organic carbon contents (up to 2.5-3.5 %), and the occurence of high mica/quartz ratios in the sand fraction. Downslope transport, presumably due to the bioturbation mechanism, is indicated by the presence of coarse shelf-borne particles (glauconite, relict shells) down to about 1000 m water depth. The fine/coarse ratio (clay + silt/sand) of the sediments from water deoth 〉 500 m never exceed a value of 11 in northern latitudes (19° - 26° N), but shows distinct maxima, ranging from 50 to 120, at latitudes 18°, 17° 15°30', and 14° N in about 2000 m water depth. This distribution is attributed to the deposition of fine-grained river load at the continental slope between 18° and 14° N, brought into the sea by the Senegal and souther rivers and transported northward ny the undercurrent. Strong calcium carbonate dissolution is indicated by the complete disappearance of pteropodes (aragonite) and high fragmentation of the planktoic foraminifers (calcite) in sediments from water depth 〉 300-600 m. Fragmentation ratios of planktonic foraminifers were found to depend on the organic carbon/carbonate ratios of the sediment suggesting that calcite dissolution at the sea bottom may also be significant in shelf and continental slope water depths if the organic matter/carbonate ratio of the surface sediment is high and the test remain long enough within the oxidizing layer on the top of the sulfate reduction zone. The fact that in the region under study intensity and anual duration of upwelling decrease from north to south is neither reflected in the composition on the sand fraction (i.e. radiolarian and fish debris contents, radiolarian/planktonic foraminiferal ratios, benthos/plankton ratios of foraminifers), nor in the sedimentary organic carbon distribution. On the contrary, these parameters even show in comparable water depths a tendency for highest values in the south, partly because primary production rates remain high in the whole region, particularly on the shelf, due to the nutrient input by rivers in the south. In addition, several hydrographic, sedimentological and climatic factors severely affect their distribution – for example currents, dissolution, grain size composition, deposition of river load, and bulk sedimentation rats.

    Description: A new species of Pycnogonida, Anoplodactylus ophiurophilus, is described. It is associated with three species of the genus Ophiocoma in the Seychelles (Indian Ocean) and constitutes the first recorded case of a sea spider found on Ophiuroidea. In comparison with the 83 species actually recognized in Anoplodactylus, the new species shows hardly any morphological adaptations due to this remarkable association.

    Description: The paper published 1963 by Illies & Botosaneanu on \xe2\x80\x9cProblems and methods of the classification and ecological zonation of running waters\xe2\x80\x9d, has attracted the attention of many hydrobiologists working on running waters; rather many of them used the system of longitudinal (vertical) zonation in their own studies, or/and critically discussed this method. An attempt is here made to critically review almost the entire bibliography on the subject published these last 15 years (about 50 titles). This review shows that meanwhile the theory of zonation has significantly developed, that it has vigorously stimulated research and discussion in different parts of the world, and that it is partly responsible for the progress achieved these last years by the rheobiological research. Original observations by the author during his research work in the Carpathians are also recorded.

    Description: Three new freshwater triclads are described from Tasmanian lakes. Two of these represent the first records of the genus Spathula in Tasmania and the third belongs to the endemic genus Romankenkius. The taxonomic affinities of the species are discussed and keys to all the Tasmanian genera and species are provided. These keys are to be regarded as provisional since it is likely that there remain many planarian species to be discovered and described from Tasmania.

    Description: Eine neue Gattung und Art der Familie Parabathynellidae, Psalidobathynella stocki gen. n., sp. n., wird beschrieben. Die Tiere stammen aus einer Quelle und einem Brunnen von der Halbinsel Paraguana in Venezuela. Es handelt sich um sehr urt\xc3\xbcmliche Parabathynellidae. Da M\xc3\xa4nnchen bisher nicht bekannt sind, ist es schwierig, die phylogenetische Stellung der neuen Gattung zu ermitteln.

    Description: Branches of gorgonians belonging to four different Mediterranean species (Eunicella singularis (Esper), Paramuricea clavata (Risso), Corallium rubrum (Linnaeus) and Lophogorgia ceratophyta (Linnaeus)) were transplanted to different habitats by means of three different methods, and survival and growth rates were observed over periods ranging from three months to over two years. It was concluded that transplantation of animals still fixed on their natural substratum is to be preferred over transplantations involving artificial devices. Transplanted adult branches of all four species tolerate conditions under which the species are not usually encountered. Tolerances or preferences of larval and juvenile phases must account for these discrepancies. Transplants never survived in shallow waters. Algal competition, abrasion and mechanical destruction due to turbulent water conditions, and in some cases high irradiance values are among the lethal factors. In deeper water, sedimentation is also fatal, although in nature some colonies survive under similar conditions.

    Description: Dugesia gonocephala (Dug\xc3\xa8s, 1830) and D. polychroa (Schmidt, 1861), collected from the Greek island of Corfu, have been investigated karyologically. The former is a sexual diploid (2n = 16) in which all the chromosomes are metacentric. The latter is a sexual diploid (2n = 8) with one submetacentric and three metacentric chromosome pairs.\nWithin the Dugesia lugubris-polychroa complex seven biotypes are known. The karyotype of D. polychroa from Corfu is most similar to biotype G from the western Mediterranean. However, there are subtle karyological and morphological differences between the two forms and thus the Corfu population is not assigned to biotype G but is considered to have been derived independently from the basic biotype A. Thus it represents an eighth biotype within the species group.

    Description: This catalogue contains information on the meteorite collections presently on display or on storage in The Netherlands. It is organized in three separate listings. The first and shortest listing gives the meteorite names grouped according to their classification. The second listing is the main body of this catalogue and gives the meteorite names in alphabetical order with specific information on place and date of fall or find, classification, chemical and structural composition, registration number and weight. This information is mainly based on the \'Catalogue of Meteorites\' by Hey (1966) and the \'Appendix to the Catalogue of Meteorites\' by Hutchison, Bevan & Hall (1977). The third listing gives the meteorite names and their classification grouped separately for each of the eight participating institutions in numerical order of the registration numbers.

    Description: A study has been made of the receptaculite Tetragonis sulcata d\'Eichwald, 1860 in Upper Ordovician erratics from the northern Netherlands. D\'Eichwald\'s original description is reviewed, giving a wider conception of the morphological diversity of receptaculites. Tetragonis sulcata is placed in the family Tetragonaceae Rietschel, 1969 (nomen correctum), together with Lepidolites dickhauti Ulrich, 1879. The aim of this study was to reconstruct the living receptaculite organism by documenting homologies between Tetragonis sulcata and receptaculites described in the literature. Through analysis of a diverse set of morphological features which thus were obtained, an attempt could be made to determine the pattern of receptaculite morphogenesis. This study therefore concentrates on the functional morphology, growth, and calcification of meroms which are extensively reviewed, particularly with respect to receptaculite growth. The geometry of merom distribution as a result of polar growth of receptaculites has been studied. A description is given of a merom arrangement not yet considered before, the Tetragonis type, which is compared with the normal, Receptaculites, type. Controversial issues, such as the position of soft parts in receptaculites as well as their life orientation, are discussed with regard to their palaeobiological significance. This approach produced some arguments against an apex-down orientation, as proposed by Campbell et al. (1974). Based on these data, the systematic position of receptaculites is analysed. Consequently, it is inferred that they should be regarded as calcareous algae. Comparison with representatives of the chlorophyte order Dasycladales provides sufficient arguments to establish the separate order Receptaculitales within the Thallophyta.

    Description: Extensive frequency data are used for a reconstruction of Devonian cunodont apparatuses. Correspondence analysis and a related clustering method are selected as statistical tools, and are used as informal methods for testing a priori hypotheses rather than as search mechanisms. In our view, the Palmatolepis apparatus consists of palmatolepan P elements, tripodellan or nothognathellan O elements, palmatodellan and smithiform N elements, and a symmetry transition consisting of falcodontan A1 elements, asymmetrical scutulan A2 elements, and symmetrical scutulan A3 elements. A peculiar phenomenon, already described by other authors, is the numerical dominance of the P elements, which are on the average 15 times as frequent as corresponding O and N elements. It is argued that this phenomenon is not due to post-mortem processes. Several biological explanations are considered. The O elements corresponding to various palmatolepan elements are identified, and this result allows a critical reappraisal of phylogenetical views based on the P elements alone. Results broadly support current views. We recognize five subgenera: Manticolepis, Tripodellus (= Deflectolepis), Palmatolepis, Panderolepis, and Conditolepis (new subgenus). Our most important result with respect to other apparatuses is the strong evidence that \'Icriodus\' and simple cones, contrary to the prevailing opinion, did not belong to a common apparatus.

    Description: A revision with keys to and descriptions of the 5 Malesian species of Ochrosia Juss. (2 n. sp.) and 6 of Neisosperma Raf. Several species names are reduced. All types are mentioned. A selected number of specimens is cited; a full list of collectors will appear in the series Identification Lists of Malesian Specimens.\nBleekeria Hassk. and Excavatia Markgr. are reduced to Ochrosia. In the note under Ochrosia there is a full discussion of the differences between this genus and Neisosperma, especially of the fruit for which some old types were microscopically examined. In Ochrosia the fruits are apocarpous, but in one species they are connate for one third, while in a new species from Flores they are united into a syncarpous, 2-celled drupe.\nIn spite of the diversity of the fruit-structure in the two genera, they are very similar in flowers and vegetatively. For this reason, the key to the species in Ochrosia is preceded by a general (tentative) key to the species of both genera for practical purpose of identification of flowering material.

    Description: Leersia oryzoides (L.) Sw. in Twente teruggevonden. Blijkens het verspreidingskaartje bij het artikel van wijlen Prof. D. Bakker in Gorteria 9 (5), p. 155\xe2\x80\x94158 waren tot dusver uit Twente geen recente vondsten van het rijstgras bekend. Na jarenlang tevergeefs zoeken vond ik in augustus 1978 dit gras aan het Kanaal Almelo-Nordhorn en wel verder westelijk dan waar het eertijds was gevonden, namelijk ten zuiden van Mekkelenberg (gem. Tubbergen). Enkele grote pollen Leersia groeiden daar op een open plek aan de waterkant; later, in oktober, stonden ze in ondiep water. De rietkraag was ter plaatse over enkele meters onderbroken, de kanaalberm was grazig en vrij sterk betreden: kennelijk betrof het een visstek. Enkele decimeters hoger in de zonering stond Triglochin palustris, een soort die mij overigens van het Kanaal Almelo-Nordhorn onbekend is en die in Twente zeer zeldzaam is geworden (ik vond haar ongeveer tien jaar geleden nog op de Fayersheide bij Vriezenveen en in de Hazelbekke bij Vasse).\nOndanks langdurig zoeken werden langs het kanaal geen andere vindplaatsen van Leersia oryzoides aangetroffen. Drs. H. Reimerink (Prov. Planol. Dienst, Zwolle) deelde me mee dat het rijstgras voor enkele jaren was aangetroffen in het gebied van de Loolee, iets verder zuidelijk. Voorts berichtte Drs. J. A. Hoekstra (Nijmegen) naar aanleiding van Prof. Bakkers artikel een vondst in de warme zomer van 1959. Leersia groeide toen in weinig exemplaren langs de oever van de afgesneden Vecht-arm tussen Junne en Beerse, ten oosten van Ommen, aan de zuidzijde van de Overijsselse Vecht. In later jaren kon de soort ter plaatse niet meer worden teruggevonden.

    Description: Over het vroegere voorkomen van Chenopodium vulvaria L. in Nederland. Naar aanleiding van een recente vondst van Chenopodium vulvaria bij Assendelft schrijft MENNEMA (1977): \xe2\x80\x9eMet P. Heukels, die het verspreidingskaartje gereed maakte voor de Atlas van de Nederlandse Flora, ben ik van mening, dat in Nederland alleen Z.-Limburg tot het areaal van C. vulvaria mag worden gerekend\xe2\x80\x9d. Hierbij zou ik de volgende kanttekeningen willen maken: C. vulvaria wordt onder de naam Atriplex olida door VORSTIUS (1633) voor de omgeving van Leiden en door BRUMAN (1662) voor die van Zwolle opgegeven. MEESE (1760, p. 15, nr. 113) geeft op: \xe2\x80\x9eOveral in Moes-hoven, en aan de weegen\xe2\x80\x9d, BRUINSMA (1840, p. 57, als C. foetidum): \xe2\x80\x9ebij Harlingen en Leeuward.\xe2\x80\x9d Dat deze soort, hoewel behorend tot de \xe2\x80\x9emoeilijke\xe2\x80\x9d familie der Chenopodiaceae, destijds goed bekend was moge blijken uit de volgende passage bij DE LOBEL (1581), die haar op p. 308\xe2\x80\x94309 beschrijft onder de naam \xe2\x80\x9eCleyn stinckende Melde ghenoemt Cuttencruydt\xe2\x80\x9d: \xe2\x80\x9e...Den reuck heeft dit cruydt zeer bekendt ghemaeckt ende bycants schandelick veracht: Want den reuck van dien stinckt ghelijck eene Bock: iae men vraegt de ghene die tselfde ghewreuen hebben tusschen de vinghers/oft sy erghens ghehandelt hebben eenighe vuyle hoere/midts dat gheheel is stinckende ghelijck de vuyle ende stinckende hoeren/waer door dat ghemeynlick Cutten cruydt gheheeten wordt. Als eenighe vrouwen cleedere daer mede ghestreken zijn/soo comen de honden daer aen riecken/ende tot onnutticheyt daer door gedreuen zijnde/ comen met een stijf dinck de selfde feesteren/besonder in de kercken daer vuylen domp wassemt/ouermidts de begrauinghe der dooden/ende oock want die met gheene winden ghesuyuert en worden. Maer ten mach gheensins in spijse ghebruyckt worden.\xe2\x80\x9d Uit de vorige eeuw is in elk geval \xc3\xa9\xc3\xa9n Nederlandse vindplaats buiten Zuid-Limburg bekend, waar de soort heeft standgehouden, namelijk Zierikzee, waar zij in 1844, 1868 en 1887 werd verzameld. Als nadere vindplaatsopgave wordt bij de vondsten van 1844 en 1887 de Zelkeheuvel vermeld. Het lijkt wel zeer onwaarschijnlijk dat de soort op het in de vorige eeuw zeer \xe2\x80\x9ege\xc3\xafsoleerde\xe2\x80\x9d Duiveland twee- of driemaal opnieuw op dezelfde plek zou zijn aangevoerd.

    Description: \xe2\x80\x9eStinse plants\xe2\x80\x9d are species (almost) exclusively limited in their distribution within a certain area to old countryseats (\xe2\x80\x9estinsen\xe2\x80\x9d) and related habitats as churchyards and old ramparts. Besides introduction by man also the specific habitat of these plants is an important factor: a fertile, moist and often calcareous soil, in the past manured and dug by man. Attention is paid to the natural habitats in Germany and France of stinse plants, especially Corydalis bulbosa. These habitats are dynamic environments such as the lower parts of slopes and along brooks in woods. Close to these places also anthropogenic habitats occur: in woods along arable land, on disturbed soil, in banks along a road, under hedges etc. Here the natural environmental dynamics are being substituted by anthropogenic dynamics. For the Netherlands various categories of these stinse plants are given: 1. Species limited (almost) exclusively to countryseats and related habitats in certain parts of the Netherlands, but growing elsewhere in this country in natural habitats. These species are called \xe2\x80\x9elocal stinse plants\xe2\x80\x9d. 2. Species that are doubtfully native and only occur in countryseats etc. Their present-day distribution area borders the Netherlands, or this country lies within the distribution area but the species is extinct in the natural habitats. They are \xe2\x80\x9eDutch stinse plants\xe2\x80\x9d, just as the categories 3 and 4. 3. Species with a natural distribution area (fairly) far from the Netherlands and introduced in former times by man. They hold stand for long times and can expand in the more natural habitats of countryseats etc. They are archeophytes or neophytes and belong to the Dutch flora. In this and the following category the species that are introduced in the Netherlands since the 18th century are indicated with an asterisk (*). The other species have been introduced and cultivated since earlier times (often since the 16th century and sometimes since the Middle Ages). 4. Species also with a natural distribution area (fairly) far from the Netherlands and introduced by man. These species can only grow in more cultivated circumstances in countryseats; they do not belong to the Dutch flora. Besides those categories there is a group of species growing abundantly in countryseats etc., but they also grow abundantly in other habitats in the Netherlands. They are no real \xe2\x80\x9estinse plants\xe2\x80\x9d and they are no doubt native in this country.

    Description: In the Netherlands two groups of plants can be distinguished in Ornithogalum umbellatum L. s.l., which differ morphologically and cytologically. The first group consists of triploids and some tetraploids, the second of penta- and hexaploids and also some tetraploids. The characters of the triploids (2n = 27) are: bulbs higher than broad; bulbils few and oblong; more than 15 leaves (up to 5 mm broad) per bulb; inflorescences few-flowered (5\xe2\x80\x9412 flowers); pedicels not deflected after anthesis. The characters of the penta- and hexaploids (2n = 45, 54 respectively) are: bulbs broader than high; bulbils many, small and round; leaves up to 12 (5\xe2\x80\x948 mm broad); inflorescences many-flowered (usually more than 14 per inflorescence); pedicels always deflected after anthesis. The seed-set is extremely low in all cytotypes. Taxonomically the most plausible solution seems to assign the triploids to O. umbellatum L., the penta- and hexaploids to O. divergens Bor. The latter taxon was probably introduced from S. or C. Europe and often occurs in the Netherlands near estates and country seats. Perhaps they can be considered as \xe2\x80\x9estinseplants\xe2\x80\x9d.

    Description: Gagea lutea (L.) Ker-Gawl. is a rather rare species in the eastern part of the Netherlands, occurring chiefly in the so-called Drenthian and Subcentral European districts; besides, it is recorded from some findspots in the province of North-Holland (fig. 1). A number of records of G. lutea in literature in fact refer to other species, especially G. pratensis; a survey is given of false and doubtful records. According to HILLEGERS (1970) and TEN KLOOSTER & LANJOUW (1972), in the Drenthian district G. lutea is chiefly found in gardens and lawns and on treaded places in the shade of trees, nearly always growing within or in the close vicinity of human settlements. Inter alia, it occurs in so-called \xe2\x80\x9estinse milieus\xe2\x80\x9d (i.e., woods and parks near old buildings like castles, countryseats, churches and so on, with a herb layer that is partially spontaneous, partially consisting of old medicinal and ornamental plants) in the province of Groningen and on some places outside. In the present paper, three additional types of habitat of the species are described, viz.: 1\xc2\xb0. woods on the banks of brooks and rivers (in the eastern parts of Gelderland and Overijssel); 2\xc2\xb0. woods at the foot of slopes, often on spots with horizontally moving water in the subsoil (this type of habitat is very rare in the south-eastern part of the Netherlands and on the inner side of the dunes; one of the most beautiful localities has been destroyed); 3\xc2\xb0. brushwoods on the outskirt of coppice woods (in a few places in the north of Drenthe and the east of Overijssel). Table 1 comprises a number of \xe2\x80\x9ereleves\xe2\x80\x9d (1\xe2\x80\x9423) of these three types of habitat. They show a rather large amount of mutual similarity in vegetation composition. They are obviously richer in woodland species and nitrophilous penumbra herbs than the vegetation in the previously mentioned treaded places, lawns, etc. (24\xe2\x80\x9427). Because all localities of G. lutea in the Drenthian district represent anthropogenic habitats (for also the brushwoods mentioned sub 3\xc2\xb0 are heavily influenced by men), probably it must be looked upon as an archaeophytic species in this part of the Netherlands. In the south-eastern part of the country, however, G. lutea is a part of the original woodland vegetation; its localities in this region connect with similar localities in Germany and Belgium.\nThe four Gagea species that occur in the Netherlands constitute an ecological series in the order G. villosa\xe2\x80\x94 G. pratensis\xe2\x80\x94G. lutea\xe2\x80\x94G. spathacea. While G. villosa (rare in our country nowadays, showing a stronger decline than the other species) is restricted to habitats strongly influenced by men (treaded places and lawns; previously also in arable land), G. pratensis occurs in the same habitats but is also found sometimes in vegetations that are to a lesser degree anthropogenic. G. lutea is restricted to anthropogenic habitats only in a part of our country, growing in woods with a spontaneous herb layer elsewhere, while G. spathacea is nearly always found in semi-natural woods.

    Description: This is the first flora of macromycetes published for Mexico. The first part of it contains rather elaborate keys to nearly 600 species; the second part illustrations of all species treated, partly as line-drawings, partly as black-and-white photographs (often more than one per species). The variation of fungi represented reflects the great ecological diversity of Mexico. A list of Mexican names of fungi and lists of edible, poisonous, hallucinogeneous and wood-destroying fungi are added, as well as a Spanish glossary. The disadventage of the lack of microscopical characters in the keys is partly compensated by the presence of numerous illustrations.

    Description: The grasslands characteristic of dry sandy soils found along rivers in the nature reserves Zelderse Driesen and Rivierduintjes bij Mook have been investigated by means of the Braun-Blanquet method.\nWhereas a community with high species diversity is still found in the Zelderse Driesen, the plant cover of the Rivierduintjes bij Mook has lost all the stenotope species characteristic for the lower syntaxonomic units, due to intensive recreation and the absence of summer grazing. Such a community containing only character species from higher phytosociological units as well as accompanying species has been called a basic community (Basalgesellschaft; KOPECK\xc3\x9d & HEJN\xc3\x9d, 1974). As the word \xe2\x80\x98basic\xe2\x80\x99 suggests an original and fundamental situation, while the term \xe2\x80\x98basic community\xe2\x80\x99 is mostly used for a syntaxon which is floristically incomplete because of a disturbance, we suggest to replace the term \xe2\x80\x98basic community\xe2\x80\x99 by the term \xe2\x80\x98trunk community\xe2\x80\x99 (Rumpfgesellschaft).\nIn order to restore the original species diversity in the reserve an increase of the grazing pressure and a decrease of recreation activities are advised.

    Description: The subdivision of the Netherlands in plantgeographical districts by VAN SOEST (1929) has recently become the subject of a series of investigations by the department for the Netherlands flora of the Rijksherbarium in Leiden (MENNEMA, 1978). This paper deals with one of these investigations, a field study on the border of the Loess and the Chalk district in the South of the Netherlands. In the course of 1976 30 square kilometers were visited and an inventarisation was made of their floristic composition. The data for the distinct square kilometers were subsequently processed by means of the so-called Mennema-methody (MENNEMA, 1973), comparing them in number of species as well as on the basis of \xe2\x80\x9eecologicalgroups\xe2\x80\x9d and some critical species. Moreover, to get a general understanding of the floristic composition of the area of investigation, the species were categorised in different types of distribution-patterns, as the square kilometers were studied for their mutual similarity in terms of species-composition. All the different methods lead to the same conclusion: the Chalk district of VAN SOEST (1929) is nothing but a small-scale, winding system of those valleys where limestone can crop up, while the Loess district continues without a change outside the valleys, on the table-land. As such a situation can not be reconciled to a plantgeographical division into two separate districts, a combination of them is proposed under the name Centreurope district, a name originally used by VAN SOEST (1925), before he decided to split up the district.

    Description: The first standard-list for the Dutch flora for the year 1970, including indications for distribution frequency and socio-ecological group for all recognized native vascular plant species (VAN DER MAAREL, 1971) was followed by a second edition for 1975, which resulted from discussions amongst Dutch flora and vegetation experts (ARNOLDS & VAN DER MEIJDEN, 1976). It was planned to elucidate the revisions for the standard-list itself and the various indication figures in an accompanying booklet. This has now been postponed to the third edition (1980), but because of the general interest in the application of environmental indicators in flora statistics the new system of ecological groups should be outlined without further delay. The first system of 19 socio-ecological groups mainly reflected the major groups of higher phytosociological units (as described by WESTHOFF & DEN HELD, 1969). The present system consists of 37 groups and it is claimed to be more effective as to the indication of environmental qualities. It is based on four criteria: 1. The main natural landscape types with their semi-natural and agricultural replacement types are reflected. 2. The main environmental factor complexes: hydrology, pH, amount of organic material, and status of macronutrients can be indicated. 3. The size of the groups allows sufficient discrimination for floristic inventories of areas in the order of one sq. km (MENNEMA, 1973). 4. The groups are as homogeneous as possible with respect to the criteria 1 and 2. The term ecological group is considered the most appropriate one for such indicator groups. The main differences between old and new system are elucidated. (See table I, which presents a syntaxonomical characterization of the groups, as well as the coherence between the two systems). The assignment of species to one particular ecological group was acceptable to the experts involved in most of the cases. Difficulties were met with in the following cases: 1. Species which have become extinct or nearly so; 2. Species which indicate an intermediate position between two environmental types; 3. Species with a wide ecological amplitude; 4. Species with a narrow ecological amplitude, but indicating a gradient situation in which other factors are involved then those chosen as factors to be indicated (see above); 5. Species with different environmental preferences in various parts of the Netherlands. For case 3 some remainder groups were considered but again rejected because of their too small size. Some examples of the practical use of the ecological groups in landscape characterization and evaluation are mentioned and the principal distinction between the floristical and phytosociological approach is made clear.

    Description: The aim of this study has been to compare the ontogenetic structures of as many species of Coprinus as possible in order to obtain a better insight into their mutual relationships. The sequence of development of the parts in the first phases of primordium development has been traced with greater precision here; several degrees of rupthymenial hymenophore development have been distinguished; the veil and pileipellis structures and the corresponding terminology have been critically discussed. Finally, an attempt has been made to establish phylogenetic relationships between about 27 species, but to acheive a higher degree of accuracy in this field, ontogenetic information concerning still more species is required.

    Description: Herbs, usually glabrous, with perennial underground stems (corms, bulbs, tubers, or rhizomes) in all Mal. spp. Aerial stems usually herbaceous and annual, erect or climbing. Leaves simple, caespitose and basal, sometimes distichous, if cauline usually alternate, generally linear to lanceolate or oblanceolate especially when basal, but sometimes shorter and broader (to ovate) when cauline, usually sessile (in Asparagus and Petrosavia reduced to non-photosynthetic scales), usually with parallel venation. Stipules 0. Inflorescence terminal or axillary, usually racemose (less often at least partly umbellate) or flowers solitary, usually bracteate. Flowers bisexual (except, in Mal., Asparagus cochinchinensis and Astelia alpina), usually actinomorphic. Perianth segments almost invariably 6 in two more or less similar or less often distinctly dissimilar whorls of 3, petaloid, connate or free, the outer whorl sometimes saccate at the base. Stamens 6, inserted on receptacle or perianth; filaments connate or free, rarely forming a corona-like ring attached to the perianth; anthers basifixed or dorsifixed, rarely sessile, usually 2-celled, extrorse to introrse or rarely dehiscing by an apical pore. Ovary usually superior, of 3 (usually fused) carpels; styles 1 or 3, simple or 3-branched; locules usually 3 (1 in Tricalistra) ; ovules 1 to numerous, placentation axile, rarely basal or parietal, usually in 2 rows. Fruit usually a loculicidal or septicidal capsule or berry, rarely the ovary wall ruptured by the developing seed which develops unprotected by a fruit, perianth caducous or persistent.

    Description: In modern handbooks the development of plant systematica is given as occurring in four overlapping phases: the pioneer (or exploratory) phase, the consolidation phase, the biosystematic phase, and the encyclopaedic phase. In systematic phycology research is still largely in the pioneer phase, with scattered attempts to reach the second, third, or even fourth phase. In many cases in phycology the biosystematic phase has to precede the consolidation phase. Knowledge of algae (growing mainly in marine or freshwater environments, but also occurring in soils or snow and on rocks or trees) is quite scanty in most parts of the world, and even for taxa that are supposed to be well known, the information is often but fragmentary. The encyclopaedic phase is for most groups of algae very remote and probably it will never be attained.\nResearch on algae connected with the Rijksherbarium reflects the phases of systematic phycology.

    Description: The first substantial contribution of the Rijksherbarium towards the plant geography of Malesia and the Pacific was made by the German born J. G. Hallier in his paper \xe2\x80\x98\xc3\x9cber fr\xc3\xbchere Landbr\xc3\xbccken, Pflanzen- und V\xc3\xb6lkerwanderungen zwischen Australien und Amerika\xe2\x80\x99. In this paper he suggested that recent land connections had existed in the tropical Pacific from Japan over Hawaii to California and south to Peru and another connection in the south Pacific. His arguments besides botanical were also ethnographical and linguistic.\nH.J. Lam was not only responsible for the promotion of taxonomic research. He added chapters on phytogeography to his revisions of the Sapotaceae and Burseraceae. His papers on the subject always had a philosophical quality. He once compared phylogeny with a stream of potentialities of the genoplasm drifting in time: the genorheithrum (1938). Lam also wrote plant-geographical essays on areas with special interest: Talaud, Celebes (1945) and especially New Guinea (1934). As regards his ideas about past connections between Borneo-Philippines-Celebes-Moluccas-New Guinea he owed much to Merrill. Lam was a follower of Wegener\xe2\x80\x99s continental drift theory and he pleaded with fellow taxonomists to accept this as a working hypothesis to explain distribution patterns in the Malesian archipelago (1930). Many of his papers were in Dutch, especially of course those meant for a general (Dutch) public, such as his chapter on phytogeography in Weevers\xe2\x80\x99 book (1939) \xe2\x80\x98Het leven der planten\xe2\x80\x99 (The life of plants). He took care, however, to publish his more important ideas in English as well. Among many things Lam will be remembered for initiating a series of distribution maps of Pacific plant taxa: \xe2\x80\x98Pacific Plant Areas\xe2\x80\x99, which was to contain critical annotated maps. These should be a valuable asset to botanists, paleontologists, ethnobotanists and others. This plan was first suggested in 1939 during the sixth Pacific Science Congress at Berkeley, but World War II held up execution of the project. As chairman of the \xe2\x80\x98Standing Committee on Pacific Plant Areas\xe2\x80\x99 Lam gave a progress report after the war (1953). Realization of the project was to be achieved by Van Steenis, his successor both as director of the Rijksherbarium and as chairman of the Standing Committee.

The main purpose of the program was to test the value of various biogeographic models for explaining the insular fauna. Since in general the fauna of inland waters yields good results in biogeographic analyses, the program was mainly directed to this fauna.

    Description: In 1977 hebban we in het gebied rond Ambleteuse amfibie\xc3\xabn bestudeerd. Bij inventarisatie troffen we Triturus vulgaris, T. helveticus, T.alpestris, T.cristatus. Rana temporaria, Hyla arborea, Bufo bufo, B. calamita, Alytes obstetricans, Pelodytes punctatus en Salamandra salamandra aan. Verschillend van voorgaande jaren was dat T.helveticus midden in de duinen bij Ambleteuse werd gevonden en dat P.punctatus frequenter en ook iets noordelijker voorkwam. R.arvalis en R.esculenta zijn in tegenstelling tot \xe2\x80\x9974 en \xe2\x80\x9975 niet aangetroffen. De vangstresultaten over de afgelopen vier jaar in de poelen die wij bezocht hebben, zijn gerangschikt in een tabel. Met behulp van gemerkte dieren konden we in een klein gebied, met dicht bijelkaar gelegen poelen aantonen dat watersalamanders zich tussen de voortplantingspoelen verplaatsen, waarbij T.alpestris het meest actief is. Tevens kwam naar voren dat het hoogtepunt van de voortplantingstijd voor T.cristatus iets later valt dan voor de andere watersalamanders. Onderzoek naar eiafzet leverde op dat voorkeur voor bepaalde planten samenhangt met de morfologie en beschikbaarheid op het moment van eiafzet en dat er van specifieke relaties waarschijnlijk geen sprake is. Op plastic planten worden ook eieren afgezet, bij voorkeur vlak onder het wateroppervlak. De eieren op dit kunstmatig substraat ontwikkelen zich tot levenskrachtige larven.

    Description: Twenty-seven species of Pycnogonida are recorded from the mediolittoral and infralittoral zones in the West Indies and of the north coast of South America, including two new species. Eurycyde acanthopus n. sp. was found on the shelf off the coast of Venezuela. Anoplodactylus monotrema n. sp. is widely distributed in the area; it has apparently been confused in the past with A. robustus (Dohrn, 1881). The morphology of the latter, and of the closely related A. virescens (Hodge, 1864), is discussed. Material from Amsterdam and St. Paul islands (Indian Ocean) attributed to A. virescens, is considered to belong to a separate species, A. dentimanus. \xe2\x80\x93 The range of several species is extended. Two species of Endeis, viz. E. meridionalis (Bohm, 1879) and E. biseriata Stock, 1968, were found for the first time in the Atlantic Ocean; formerly they were recorded from the Indo-West Pacific only. An Achelia is provisionally identified as A. langi (Dohrn, 1881), a species hitherto known from the eastern Atlantic and the Mediterranean. \xe2\x80\x94 The male of Tanystylum isthmiacum difficile Stock, 1966, is illustrated for the first time; it is concluded that T. isthmiacum and T. geminum Stock, 1954, do not form a pair of vicarious species. The male sex of Ammothella exornata Stock, 1975, is also recorded for the first time.

    Description: Ahermatypic Seleractinia are very common throughout the tropical western Atlantic, both in number of species and individuals. Of the Scleractinia known from the western Atlantic, there are over twice as many species of ahermatypes (species that do not have symbiotic zooxanthellae) as hermatypes (the shallow-water \xe2\x80\x9creef corals,\xe2\x80\x9d all of which have zooxanthellae). This paper is a review of all known species of deep-water Scleractinia that occur in the Caribbean Sea and adjacent waters, all of which are ahermatypic. The term \xe2\x80\x9cdeep-water\xe2\x80\x9d is used here to designate depths equal to or greater than 200 meters; the 88 species treated all have bathymetric ranges that exceed 200 meters at their deepest points. Another 27 ahermatypic species are confined to the shallow water (0-200 m) of the Caribbean, and two species are known from off tropical Brazil but not the Caribbean, resulting in 117 species of tropical western Atlantic ahermatypes.\nThe only person to have comprehensively studied the deep-water western Atlantic corals was POURTAL\xc3\x88S, whose last publication was in 1880. In the ensuing century, large collections have accumulated and Scleractinian classification has been greatly modified. This review is based primarily on the large collections at the University of Miami (RSMAS), USNM, and MCZ.

    Description: Even a few years ago, the caddis-fly fauna of Cuba remained very poorly known. The situation notably improved, especially following the study of collections made throughout the Island, either by myself, or by Cuban entomologists (Botosaneanu & Sykora 1973, Botosaneanu 1977, Botosaneanu in press).\nAt present, somewhat less than 80 species and subspecies are known from Cuba (2 Rhyacophilidae Hydrobiosinae, 8 Glossosomatidae Protoptilinae, 6 Philopotamidae, 1 Psychomyiidae Xyphocentroninae, 6 Polycentropodidae, 6 Hydropsychidae Hydropsychinae and 3 Macronematinae, 31 Hydroptilidae, 3 Leptoceridae, 2 Odontoceridae, 4 Calamoceratidae, 5 Helicopsychidae). But we can expect some 10 additional species to be discovered. These figures are reasonably high when compared to those obtained for the other antillean Islands (see especially Flint 1964, 1968a, 1968b): for Jamaica and Puerto Rico, both well investigated and smaller than Cuba, the figures are 39 and 32 respectively; only 27 species were quoted from Hispaniola (Haiti, certainly having a rich fauna, is still very poorly known); 44 species have been reported on the whole for the Lesser Antilles. The percentage of endemical taxa is remarkably high: 61 from the 76 total. These are species of Atopsyche Bks., Cubanoptila Sykora (genus endemical in Cuba), Cariboptila Flint, Campsiophora Flint (2 purely Antillean genera), Polycentropus Curt., Hydropsyche Pict., Smicridea McL., Leptonema Gu\xc3\xa9rin, Macronema Pict., Alisotrichia Flint, Ochrotrichia Mos., Metrichia Ross, Loxotrichia Mos., Oxyethira Eat., Hydroptila Dalman, Neotrichia Mort., Oecetis McL., Marilia F. M\xc3\xbcller, Phylloicus F. M\xc3\xbcller, Helicopsyche Siebold.

    Description: Two new Hydropsyche-species from the Jordan River are described; they belong to the guttata-group, and at least one of them was regularly confused with the West European H. exocellata Duf.\nH. batavorum sp.n. is an apparently rare species, whose phallus shows features never recorded at least for the guttata-group. H. janstockiana sp.n. is much more abundant, and it is obviously nearly related to H. sciligra Mal. (Caucasus, Iran, Asia Minor, Central Asia). Both are certainly potamobionts whereas the third Hydropsyche of the Jordan River System ( H. jordanensis Tjeder. belonging to the instabilis-group) seems to be rather a rhithrobiont.

    Description: This study deals with the dorsalis group and the brevipennis group. The western palaearctic members of the dorsalis group are N. dorsalis dorsalis (Fabricius, 1781), N. quadristriata (Schummel, 1833), N. lunulicornis lunulicornis (Schummel, 1833), N. scurra (Meigen, 1818), N. austriaca (Mannheims & Theowald, 1959), and N. helvetica (Mannheims & Theowald, 1959). The eastern palaearctic subspecies dorsalis sachalina Alexander, 1924, and lunulicornis angustistria Alexander, 1925, are briefly discussed. A description is provided of N. profunda Alexander, 1935, formerly treated as a subspecies of scurra.\nThe brevipennis group assembles the Nephrotoma species from Madeira, N. brevipennis (Wollaston, 1858), N. lucida (Schiner, 1868), and N. antithrix (Mannheims, 1962). N. lucida is taken out of synonymy with brevipennis.

    Description: In the present paper Hyla ornatissima Noble is removed from the synonymy of Hyla granosa Boulenger, and resurrected as a separate species on the basis of morphological, ecological and acoustical differences. Another relative of this group occurring in Guiana is Hyla sibleszi Rivero. Because of its superficial resemblance with these frogs Hyla punctata (Schneider), of another species-group, is also treated. All four species are extensively described, data on life history and distribution are given. H. sibleszi, so far only known from the type material and some associated specimens, is reported from several new localities in Venezuela and Guyana. It is suggested that the function of the intricate dorsal pattern of H. ornatissima serves to protect the animal from predation, camouflaging it on the leaves of the trees where the animals live. A key to discern the four species is presented.

    Description: The present collection was made on the south and west coasts of Madagascar between 90 en 465 meters depth and includes 17 species of calyptoblastic hydroids, belonging to six families: Campanulinidae, Lafoeidae, Campanulariidae, Syntheciidae, Sertulariidae and Plumulariidae. Twelve are recorded for the first time from Madagascar, while three of these are new for the Indian Ocean and one is described as new (Tulpa costata). \nEndemic species represent half of the collection and are numerically more important than cosmopolitan, tropical-indopacific, and southern species. A comparative study of bathymetrical characteristics of species from Madagascar and around the world allows to distinguish three groups of species: deepsea species, which have a very wide geographical distribution and are the most eurybathic; species of median depth, which are endemic or extend towards the southern Atlantic and the Indian Ocean; species of shallow waters, mostly endemic and, in this collection, belonging to the family Plumulariidae, which is highly diversified in the infralittoral of reef biotopes.\nAn original contribution to the knowledge of the biology of Halicornaria ferlusi Billard (Plumulariidae) is given with the description of successive developmental stages linked to the colonial development. The epizootic forms of various species belonging to the genus Halicornaria were hitherto interpreted as stunted forms of typical species due to epizoism; here they are described as juvenile forms and, as a consequence, the formerly used terms variety or subspecies epizootica cannot be applied to them.\nA hypothesis of temporary epizoism is given for two species, which are epizootic during the juvenile stage only.

    Description: In this publication a revision is given of the genera of the subfamily Bulimulinae (Gastropoda, Pulmonata, Bulimulidae).\nThe morphological variation of the shell, radula, pallial organs and genitalia is analized and 21 character transition series are recognized.\nIn the systematical part the following data are presented for each genus : description of shell and anatomy, distribution, ecology, bibliography and a list of taxa. The number of (sub) genera is reduced from 80 to 43 ( + two nomina inquirenda). A new synonymy is : Paracochlea Hylton Scott, 1967 = Eudioptus Albers, 1860. The following new species names are introduced : Bostryx sophieae, Drymaeus (Drymaeus) marcapatensis, Drymaeus (Drymaeus) sophieae, Drymaeus (Mesembrinus) pseudobesus. Berendtia digueti Mabille is designated type species of Teneritia Mabille ; Helix zoographica d\'Orbigny is designated type species of Hamadryas Albers.\nBased on the transition series mentioned above, hypotheses of phylogenetic relationships are presented for the genus groups, using the methods of Hennig. The relationships between the five subfamilies of the Bulimulidae are also investigated but remain tentative.\nIn the zoogeographical section the various theories are reviewed and their relevance for the distribution of the Bulimulinae is treated, using the hypotheses of phylogenetic relationships and Croizat\'s vicariance theory.

    Description: In this paper we list seven species of caecilians known to occur in Surinam. An eighth species, the aquatic Typhlonectes compressicaudus, is likely to be found in Surinam, but there are no voucher specimens. We report the rediscovery of the rare Rhinatrema bivittatum, now known from four specimens, one each from Brazil, French Guiana, Guyana, and Surinam. Microcaecilia taylori, described as a new species from Sipaliwini, is characterized mainly by a complete lack of secondary annuli, a feature which necessitated rediagnosis of the genus Microcaecilia. A Microcaecilia from the Lely Mountains differs from all known specimens of the genus by its larger size. The specimen is either a geographic variant of Microcaecilia unicolor, or it is an undescribed species. Additional material is needed to solve the problem. The known ranges of Rhinatrema bivittatum and Microcaecilia rabei are significantly extended. A key to Surinam caecilians is provided. A discussion on zoogeography leads to the tentative conclusion that part of the 13 species of caecilians known from Guiana are widespread, but others apparently have limited distributions and might represent indicator species of former forest-refuges.

Der gleiche Fundort bleibt ein Fragezeichen, die Abbildung der beiden Holo- und Allotypen zeigt aber deutlich die Verschiedenheit.\nEine Serie Parnassius mit dem Fundort Uzun-Gir, 3500 m, KirgistanAla-Tau, liessen mich nicht zweifeln, dass sie der Species Koramius patricius Niepelt angeh\xc3\xb6ren, die der Autor dieser Art in 1914 nach 2 \xe2\x99\x80 aus dem Tianschau-Gebirge, Turkestan, beschrieben und abgebildet hat.

    Description: Herbals and herbaria for scientific purposes have been made from the 16th century. They were private property long before the time of the foundation of most institutional herbaria, in which they are now, as far as they are still intact, preserved. The oldest, when in book-form, are of course kept apart. Those mounted on loose sheets were treated in different ways and were subsequently incorporated and filed in the general herbarium, as for instance those of Van Royen at Leiden, Burman f. at Geneva, R. Brown at the British Museum and the Hooker and Bentham collections at Kew. In other instances they were kept apart and preserved as a separate unit, in view of the fact that they represented the authentic standard works of authorities, for example the herbaria of Jussieu, Lamarck, and Baillon at Paris, that of the DeCandolles at Geneva, and Willdenow at Berlin. For this purpose the Wallich collections at Kew were, in recent years, re-assembled as a separate unit.\nExcept for the Herbarium in Paris, which was founded as early as 1635, other university or national herbaria were founded much later, e.g. that of the British Museum (Natural History) in 1753 (harbouring several famous herbals from Sloane, Petiver, etc.), Copenhagen in 1759, of the University of Cambridge in 1761, Uppsala in 1785, Berlin in 1815, Geneva in 1817 (now comprising the combined herbaria of Delessert and Boissier, and the separate herbarium of the DeCandolles), Petersburg (now Leningrad) in 1823, the Rijksherbarium at Brussels in 1829, and the Herbarium at Kew as late as 1853.

    Description: The inadequacies of the original descriptions of Sagitta decipiens Fowler, 1905, and S. sibogae Fowler, 1906, have led to confusion concerning these species. Sagitta neodecipiens Tokioka, 1959, is a junior synonym of S. decipiens Fowler, 1905. S. sibogae Fowler, 1906, is the valid name for the species usually incorrectly named S. decipiens (non Fowler, 1905) because of the redescription of Ritter-Zahony (1911). S. philippini Michael, 1919, is a junior synonym of S. sibogae. The two valid species are redescribed from the types, and lectotypes have been designated.

    Description: A lectotype is selected \xe2\x80\x94 and its skull figured, for the first time \xe2\x80\x94 for Dobsonia pannietensis (De Vis, 1905), which is considered to be a good species. Specimens have been examined from the Louisiades, the D\xe2\x80\x99Entrecasteaux Group, Trobriand Island and Woodlark Island. The species varies per island or island group in dimensions and/or proportions. The skull of the holotype of Dobsonia remota Cabrera, 1920, is figured \xe2\x80\x94 also for the first time. The possible synonymy of this species with D. pannietensis is discussed. The holotype, from Trobriand, is still the only known specimen. Specimens from Bougainville, Solomon Islands, referred to remota by McKean (1972), are in fact juvenile Dobsonia inermis Andersen, 1909.

    Description: A collection of frogs was made in Madagascar between November 1970 and May 1973. Observations in the field and investigations in the laboratory yielded a variety of new taxonomic characters, such as the morphology of eggs and larvae, the reproductive behaviour, the habitat and habits of both the terrestrial and aquatic stages, the mating call and the colouration in life. Karyotype studies and researches on the nuclear DNA amount of these frogs were published previously.\nBecause of various contradictions between the results of this study and the current classification, both these new and the more convential morphological characters were used for a re-evaluation of the systematics of the Mantellinae Laurent, 1946. As a result, this subfamily can be considered once more a natural, probably mono-phyletic group of ranid-type frogs, primarily separated from the others by a different mating behaviour.\nOf the genera Mantidactylus Boulenger, 1895, Mantella Boulenger, 1882, and Aglyptodactylus Boulenger, 1919, 35 species, collected by the author and representing about 70% of the known species, are treated.\nThe genus Aglyptodactylus is excluded from the Mantellinae. The genus Gephyromantis Methuen, 1919, is synonymized with Mantidactylus. The broadened genus Mantidactylus is divided into 10 species groups: guttulatus group, ulcerosus group, lugubris group, albofrenatus group, aglavei group, asper group, boulengeri group, wittei group, depressiceps group, pulcher group. These groups reflect the adaptive radiation within this genus.\nTwo new species are described: viz. Mantidactylus flavobrunneus and M. punctatus. Lectotypes are designated for Rhacophorus depressiceps Boulenger, 1882, Rhacophorus pulcher, Boulenger, 1882, Rhacophorus liber Peracca, 1893, and Gephyromantis methueni Angel, 1929.\nThe following new combinations, new synonyms and bonae species are proposed: Mantidactylus grandidieri Mocquard, 1895, bona species (syn. Mantidactylus piger (Mocquard, 1900)); Mantidactylus opiparis (Peracca, 1893), bona species (syn. Mantidactylus melanopleura (Mocquard, 1901) and Mantidactylus frenatus Boettger, 1913); Mantidactylus aglavei (Methuen & Hewitt, 1913), comb. nov. (from Rhacophorus); Mantidactylus boulengeri (Methuen, 1919), comb. nov. (from Gephyromantis); Mantidactylus eiselti (Guib\xc3\xa9, 1975), comb. nov. (from Gephyromantis); (Guib\xc3\xa9, 1975), comb. nov. (from Mantidactylus blommersae Gephyromantis); Mantidactylus domerguei (Guib\xc3\xa9, 1974) comb. nov. (from Gephyromantis); Mantidactylus peraccae (Boulenger, 1896), comb. nov. (from Rhacophorus); Mantidactylus tornieri (Ahl, 1928), bona species; Mantidactylus pulcher (Boulenger, 1882) comb. nov. (from Gephyromantis); Mantidactylus liber (Peracca, 1893), comb. nov. (from Gephyromantis), bona species (syn. Gephyromantis albogularis Guib\xc3\xa9, 1947 and Gephyromantis variabilis Millot & Guib\xc3\xa9, 1951); Mantidactylus bicalcaratus (Boettger, 1913), comb. nov. (from Gephyromantis) (syn. Gephyromantis methueni Angel, 1929).

    Description: The karyotype of the Namaqua chamaeleon, Chamaeleo namaquensis Smith, 1831, has 24 chromosomes consisting of 12 macro- and 12 microchromosomes. This chromosome pattern is characteristic of the C. chamaeleon (Linnaeus, 1758) species group and indicates that C. namaquensis is a member of that taxon. It is hypothesized that C. namaquensis and C. chamaeleon are the most ecologically specialized and recently evolved taxa in the chamaeleon group.

    Description: Eleven species of helminth parasites (five acanthocephalans, five cestodes and one trematode) are reported from altogether sixteen fish hosts in the Rh\xc3\xb4ne River, N.E. of Lyon.\nThe most common parasite is Pomphorhynchus laevis, which occurs in all fish species examined. Echinorhynchus borealis seems to he restricted mainly to Burbot. Metechinorhynchus truttae was not frequently met with, but was very numerous in Grayling from the river Furans. Acanthocephalus anguillae was found in fishes from the so-called \xe2\x80\x9dl\xc3\xb4nes\xe2\x80\x9d (backwaters). A. lucii was rarely encountered during the present study. Of Cestoda, Caryophyllaeus laticeps is confined to fishes feeding on muddy substrates, Bathybothrium rectangulum was found in Barbel, and Eubothrium rugosum in Burbot. Proteocephalus torulosus is recorded from Dace and Chub, and Cyathocephalus truncatus from Trout and Grayling. The trematode Crepidostomum farionis occurred in the latter as well.

    Description: The systematic arrangement of the worm snakes (Typhlops) from the continental western hemisphere is presented. Allocations of many names historically assigned to Central and South American Typhlops are clarified. The continental Typhlops include nine species, two of which are described as new. The intraspecific variation of all species is explored within the limitations of known specimens. Three major radiations of New World Typhlops are postulated to account for the radiations of the present species groups.

    Description: The Laetolil Beds in Tanzania, 20-30 miles south of Olduvai Gorge, have been extensively sampled by parties under the leadership of Mrs. Dr. Mary D. Leakey, who very kindly sent me Hipparion material collected in 1974, 1975, and 1976. In a restudy of proboscidean material from these beds described by Dietrich (1942), Maglio (1969) arrived at the conclusion that the Laetolil fauna represents two distinct horizons, one seemingly correlating best with Kanapoi, Yellow Sands (= Mursi Formation), Chemeron, and Kanam, and younger deposits correlating best with the later Omo Beds, possibly antedating Olduvai Bed I but only by a short time interval. This has been confirmed by radiometric dating: the Laetolil Beds with the older fauna are bracketed in time between 3.8 and 3.6 million years whereas the lava flows unconformably overlying them are dated at 2.4 million years. The younger deposits which are to be named Ndolanya Beds, therefore, have an age older than 2.4 million years, and have also produced fossils (Leakey et alii, 1976).\nThe fossiliferous deposits in the Laetolil area have been subdivided into 26 localities from most of which I received Hipparion material, all collected in situ. Two localities, 7 East and 18, are in the Ndolanya Beds, while the others are in the Laetolil Beds (Mary Leakey, personal communication). The fossils found in situ are cream coloured or white, sometimes chalky in texture. Surface material also including brown, grey or black specimens, often rolled, has been excluded. It is among the surface material that Equus is represented.\nHowever, there is no evidence that the equid material from the Laetolil Beds proper includes any genus but Hipparion.\nI am most grateful to Mrs. Mary Leakey for entrusting this material to me; it comes from a critical time phase in the evolution of African hipparions as

    Description: During a stay at the Galapagos Islands (1975-1976), one of us (Ch. de Ridder) made a study of Gorgonaria and Antipatharia, paying special attention to commensals found with these corals.\nOn Antipathes galapagensis Deichmann, 1941, a species of the pontoniine shrimp genus Pontonides was observed, which proved to be new to science.\nThe present paper describes the new species and its living conditions.\nPontonides sympathes new species (figs. 1-3) Material examined. \xe2\x80\x94 Punta Pitt, north-east coast of San Cristobal Island, Galapagos Archipelago, Ecuador; on Antipathes galapagensis Deichmann growing on a lava bottom at a depth of 8 m; surface water temperature 23.9oC; 2 February 1976; Ch. De Ridder leg.; I ovigerous female holotype, and 29 paratypes.\nSpecimens of this species, on the same host, were observed in two other localities in the Galapagos Archipelago: near Daphne Major Island (depth 10 to 23 m), and near Champion Island (depth about 15 m). These specimens, however, were not collected.\nDescription. \xe2\x80\x94 The carapace is somewhat depressed. The rostrum is broad, short, and depressed; it reaches slightly beyond the base of the eyes and fails by far to reach the base of the antennular peduncles. It is flat and wide; its midrib is elevated, but rather low, unarmed and with a blunt dorsal angle in about the middle of its length. The lateral margin of the rostrum bears a distinct, though small tooth; in one of the specimens, on one of the lateral margins a second tooth is placed immediately behind the first, in all other specimens each lateral margin has only a single tooth. The margin between the tip of the rostrum and the lateral tooth runs obliquely backward

    Description: Three years of fieldwork in the El Manteco region by the junior author formed the basis for the checklist presented here. Among the frogs assembled is a small species of Ololygon, new to science, also found in Guyana and Surinam. The anuran succession in the temporary lagoons, formed during the rainy season, was studied during three years and a consistent pattern was found. Comparisons with the llanos fauna are made and it is concluded that the El Manteco region contains a relatively large percentage of Amazonian elements, absent from the llanos.

    Description: Rejecting without valid argumentation a lectotype selection for Raja kenojei M\xc3\xbcller & Henle, 1841, by the present author (1947), Ishiyama (1967) indicated another of the four Leiden types as such. Both selected specimens are shown to represent only the different sexes of the same species, which is not conspecific with R. kenojei sensu Ishiyama et al. (= ? R. japonica Nystr\xc3\xb6m, 1887) but rather with R. porosa G\xc3\xbcnther, 1847, as understood by Ishiyama. One of the R. kenojei types is referred to R. meerdervoortii Bleeker, 1860, a distinct species not identical with R. kenojei in either interpretation, and of which R. macrophthalma Ishiyama, 1950, may well prove to be a junior synonym. M\xc3\xbcller & Henle\'s coloured illustration of R. kenojei, made after a Japanese original, evidently represents a juvenile rajid specimen of uncertain identity.

    Description: Herr Blom hat von seiner Sammelreise 1978 nach Iran zwei Serien von Allancastria louristana (Le Cerf) mitgebracht, erbeutet 8. bis 10. und 16. bis 18. April in der Umgebung von Yasuj (Ostan Boyr Ahmadi), 400 km s\xc3\xbcd\xc3\xb6stlich von Tchahar Dooul a Girmanschah in Luristan Arrak (W. Iran), die Type-Lokalit\xc3\xa4t von A. louristana (Le Cerf). Dieses Material haben wir verglichen mit den 11 \xe2\x99\x82 und 5 \xe2\x99\x80 von A. louristana in der Sammlung C.\nEisner im Rijksmuseum van Natuurlijke Historie, Leiden. Obwohl diese Serie als Fundorte nur \xe2\x80\x9eLouristan" und \xe2\x80\x9eS\xc3\xbcd-Persien" aufweist und auch individuell ein wenig variabel ist, sind wir \xc3\xbcberzeugt, dass die von Blom erbeuteten St\xc3\xbccke einer eigenen Unterart angeh\xc3\xb6ren, die wir boyrahmadiensis nennen.\nBeim Vergleich haben wir feststellen k\xc3\xb6nnen: ssp. boyrahmadiensis ist im Durchschnitt kleiner als ssp. louristana, 23-25 mm gegen\xc3\xbcber 23,5-26 mm.\nVor allem aber ist die neue Unterart (pl. 1 fig. 1-2) sichtlich schw\xc3\xa4cher gezeichnet, die Schwarzelemente sind schmaler ausgepr\xc3\xa4gt, bei ssp. louristana (pl. 1 fig. 3) gross und rund, bei ssp. boyrahmadiensis l\xc3\xa4nglich und viel kleiner, die Fl\xc3\xbcgelwurzel ist weniger schwarz \xc3\xbcberpudert, die Hinterrandsschw\xc3\xa4rze schmaler; die Rotpigmente im Vorderrandsfleck, im Analfleck und die rote Fleckenreihe im Hinterfl\xc3\xbcgel bei ssp. louristana sind bei ssp. boyrahmadiensis nahezu erloschen oder verschwunden. Das ist auch bei den Weibchen der Fall. Die circumdiscalen Flecke sind reduziert, die Submarginalbinde des Hinterfl\xc3\xbcgels unterseits blasser gr\xc3\xbcn, und beide sind oberseits kaum durchschlagend.\nHolotypus \xe2\x99\x82, Iran, Ostan Boyr Ahmadi, Yasuj Abshar, 2000 m, 8-io.iv. 1978, leg.
