    In:  Mededelingen van het Botanisch Museum en Herbarium van de Rijksuniversiteit te Utrecht (2352-5754) vol.194 (1963) nr.1 p.17
    Publication Date: 2015-05-08
    Description: 1. The chromosome numbers of 10 species of the genus Viola in the Netherlands were determined. 2. Viola riviniana has various chromosome numbers: 2n = 35, 40, 45, 46, 47 (most often 2n = 40). 3. It was not possible to find a correlation between the external morphology and the various chromosome numbers in V. riviniana. 4. Despite the variability of V. riviniana it proved impossible to divide the Dutch material into subspecies. 5. Some differential characters of V. riviniana and V. reichenbachiana are described. 6. V. canina is not variable in cytological respect in the Netherlands. 7. V. calaminaria is not related to V. lutea but to the V. tricolor complex.

    Description: 1. The Orchids in the Netherlands have been subjected to a cytological investigation. 2. The division of the genera Orchis (L.) Klinge into two new genera: Orchis (L.) Vermln. and Dactylorchis (Kl.) Vermln. (Vermeulen, 1947), could be confirmed. 3. In Listera ovata (L.) R. Br. the diploid chromosome number is 34. Deviating numbers 2n = 35 and 2n = 36 were counted. Because aberations in chromosome number do not cause morphological differences these aberations seem to be unimportant. 4. Out of the material investigated it might be concluded that for the moment it does not seem to be correct to consider Dactylorchis fuchsii (Druce) Vermln, as a separate species besides Dactylorchis maculata (L.) Vermln. It seems more likely that D. fuchsii and D. maculata represent two types within a complex-species.

    Publication Date: 2015-04-20
    Description: As a student, I used to enjoy ’Karsten and Schenck’ propped up on the breakfast-table. With equal familiarity I treated ’Kerner’, 'Schimper', and other great picture-books of botany. The time came to translate the dreams of youth into vocation. ”Protista”, said the professor of zoology, ”are the pivot of biology”. I substituted my breakfast-reading with the Archiv für Protistenkunde, and hesitated at the coming call of biophysics. Ever since I have been rent, like the morning toast, by two forces which would make of me a student of the microcosm of protoplasm and a disciple of its greatness. They are the forces splitting biology into macromolecules and macro-organisms, and I do not know how this rift may be spanned. I cannot conceive what energy level, chemical bond, or carbon-grouping can decide whether it is insect-pollination or curiosity that will be inherited. But the pendulum has swung. The young botanist no longer looks at these books? he models molecules and chromosomes, and works very largely in vitro. Nevertheless, if biology is not to stand still, the pendulum will return and its amplitude will be the strength of those who have put their trust in the macrocosm. These were the thoughts which I vaguely entertained, when I found myself in the forests of Malaya and I measured my insignificance against the quiet majesty of the trees. All botanists should be humble. From trampling weeds and cutting lawns they should go where they are lost in the immense structure of the forest. It is built in surpassing beauty without any of the necessities of human endeavour; no muscle or machine, no sense-organ or instrument, no thought or blueprint has hoisted it up. It has grown by plant-nature to a stature and complexity exceeding any presentiment that can be gathered from books, and it is one of the most baffling problems of biology.

    Description: Different trees have different sorts of hark, the variation is of two main kinds. The hark of an individual changes as it grows, and there are differences between mature trees of different species. The recognition of large trees in tropical forest depends on living as opposed to herbarium characters and amongst living characters baric is important. Botanists are slowly coming to realise that living characters are of importance to taxonomy and can supplement the characters visible on herbarium sheets but often hard to see in the forest (Corner 1940, Symington 1943, Henderson & Wyatt-Smith 1956). At present many living characters are used empirically if at all.

    Description: Archer, Mildred: Natural History drawings in the India Office Library. London. H.M. Stat. Office 1962. ix + 116 pp., 25 pl. Clothbound Sh. 27/6. This is a catalogue of the c. 5000 drawings still extant in the India Office Library of which only a few hundreds are of plants, the rest representing animals. There is an extensive introduction in which the activities of the persons involved in their donation are explained, which gives the book an interesting biographical and historical aspect. A beautifully executed work showing wide knowledge of its author. -- v. St. Fleming, Charles A.: New Zealand Biogeography. Tuatara 10, 1962, 53-108, 15 fig.

    Description: The present investigation arose from a discussion between Dr van Steenis and Mr C. T. White in July 1950 concerning a plant from North Queensland, collected by Mr L. J. Brass. The specimen was pre-identified as an Aristotelia but also showed similarity with the Papuan genus Sericolea. The need was felt to investigate the distinction between the two genera. Mr White was very keen to investigate the problem himself but this was unfortunately prevented by his untimely death, only two weeks after this discussion. The problem has rested ever since, until in 1963 I had to verify the distinction between the two genera for my work on the Pacific flora, a work executed under a grant from the Netherlands Organisation for the Advancement of Pure Research (Z.W.O.).

    Description: The flowering specimens of Glyptopetalum are very difficult to separate from those of Euonymus except by examining the number of ovules in each cell of the ovary. The ovules are mostly 2, rarely 3—12, per cell in Euonymus and there is only one in Glyptopetalum. However, the genus Glyptopetalum can be easily distinguished from Euonymus, or recognized, by the characteristic persistent columella of the fruit and the branched raphe of the seed (cf. also Fl. Mai. 1, 5, 1963, 256 and fig. 711). In preparing the Celastraceae for the Flora Malesiana, two additional extra-Malaysian species of Glyptopetalum have been found: a new one from Thailand and a new combination for the flora of China. The range of distribution of this genus is now extending to southwestern China.

    Description: There is a great diversity of opinion regarding the interpretation of the genera and some species in the former Hippocrateaceae. If one reads the comprehensive and detailed revision of the New World Hippocrateaceae by A. C. Smith (Brittonia 3, 1940, 341—555), one may have an impression of it. For example, A. C. Smith in his monotypic genus Hemiangium, under H. excelsum, has united species which were recognized as belonging to three different genera by Miers; he has also limited Hippocratea L. to a single species, H. volubilis L., and placed more than 40 names of species and varieties in the synonymy of it. A detailed review of the history and generic delimitation of the family Hippocrateaceae has already ably been summarized and discussed by A. C. Smith in the above mentioned publication. I shall make only a brief account of those works which contain genera, species, or discussions related to the Malaysian flora.

    Description: Dacryodes nervosa (H. J. Lam) Leenhouts, nov. comb. — Santiria nervosa H. J. Lam, Ann. Jard. Bot. Btzg 42 (1932) 206; Leenh., Fl. Males. 1, 5 (1956) 233. Though the fruits were unknown, this species was included in Santiria, probably on account of the stellate hairs, in the Burseraceae furthermore known then only from Santiria conferta ¹). Only recently a fruiting specimen came at hand from Sarawak, Borneo ( Sarawak For. Dep. 13389), and the fruits mark it to be typical Dacryodes. As it is not identical with any known species of the latter genus, a new combination had to be made.

    Description: Being engaged during several years with a revision of the grasses preserved in the Rijks-Herbarium at the University of Leyden, my attention was called to the group of the Stipeae, and especially to the very difficult genus of Aristida. After an exhaustive study of the literature, I thought it desirable to have a monograph of this genus, containing extensive keys for the determination of all the species hitherto known, and I resolved to prepare such a work. It has been my good fortune that I had at my disposal not only the valuable collections of the Rijks-Herbarium, but that by the courtesy of the directors of the great herbaria in Europe and in America, I could study many thousands of specimens, among them authentic specimens and types. So several years elapsed before the revision was finished. Before I am going to publish my work, it seemed desirable to prepare a preliminary paper on the subject, dealing with the literature studied and the results of the critical examination of the types, moreover the new species found in herbaria are included in this paper. To find easily the original description and the type specimen, I give in alphabetical order all the species and varieties hitherto described, no matter if they are accepted in my monograph as valid or not.

    Description: The kindness of Dr. GOETHART has enabled me to investigate all the Myxomycetes (Myxogasteres, Mycetozoa) which are kept in the Rijks-Herbarium at Leyden. Among the older collections I found those of PERSOON, V. HALL, HANKARL, BUSE, JUNGHUHN, WAGNER. Only a little part of these collections remains, owing to the way, in which the above-mentioned collectors used to conserve their materials.

    Description: The holothurians from the southern end of the Caribbean area are incompletely known. CLARK (1919) discussed a few specimens taken from Tobago, British West Indies, and DEICHMANN (1926) prepared a report on the holothurians from the Barbados-Antigua Expedition. ADA TEN BROEKE (1927) listed 7 holothurians from Curaçao, collected by C. J. VAN DER HORST. This list constituted the first mention of holothurians from the area. CLARK (1933) listed one additional specimen in his “Handbook of the Littoral Echinoderms of Porto Rico and the Other West Indian Islands”. ENGEL (1939), included three additional sea cucumbers in his report on the echinoderms which were gathered by P. WAGENAAR HUMMELINCK. Neither ENGEL (1939) nor TEN BROEKE (1927) described their specimens. I have found three additional species new to the fauna of the above islands. Two of these specimens, Thyoneria cognata and Trachythonidium occidentale are the first Dendrochirota to be reported from the Netherlands Antilles. After this report has been completed, ELISABETH DEICHMANN (1963) produced a short survey of the ‘Shallow water Holothurians known from the Caribbean Waters’ in which several new data are to be found gathered from material which was collected by WAGENAAR HUMMELINCK in 1948/49 and 1955.

    Description: Von den “Inseln unter dem Winde”, dem südlichsten, in Ost-Westrichtung dem Festland von Venezuela vorgelagerten Teil des Antillenbogens, waren bisher keiner Gyriniden bekannt. Erst kürzlich erfuhr ich durch Dr. P. WAGENAAR HUMMELINCK, Utrecht, dass auf Curaçao, einer der westlichsten dieser Inseln, Vertreter dieser Käferfamilie erbeutet worden seien, deren Sammler, Ir. R. H. COBBEN von der Landbouwhogeschool in Wageningen, mir seine Ausbeute entgegenkommend zum Studium zur Verfügung stellte. Beiden Herren danke ich hiermit bestens für ihre Freundlichkeit. Das Material war besonders interessant hinsichtlich seiner faunistischen Zusammensetzung, denn während die eine der in ihm enthaltenen Arten festländischen Ursprungs ist, gehört die andere zur karibischen Fauna. Bemerkenswert ist auch, dass beide Arten trotz des abgelegenen Fundorts keine wesentlichen rassischen Besonderheiten aufweisen.

    Description: The solution of the problem whether the ultrabasic inclusions in lavas are accumulation products of early crystallized minerals of the lavas in which they occur, or fragments of the earth’s peridotite shell carried to the surface by the eruptive force of the lavas, largely depends on the answer to the question whether these inclusions are tectonites or not. The structure of the specimens from Auvergne (France), which formed the main subject of this study, has been proved conclusively to be of a tectonic nature, from the macroscopically visible intersecting slip planes which are definitely younger than the banding of the specimen, as well as from microscopic evidence that suggests that both the olivine and enstatite crystals are concentrated in the intersecting slip planes. The fabric of olivine and enstatite proved to be symmetrical in respect of these slip planes, although remnants of an initial, predeformational orientation related with the banding still persist. In order to establish the relation between the old and the new fabric a comparative study of the fabric of a nodule from Dreiser Weiher (chapter II) and the crystal orientation of the banded sample from Auvergne (chapter III) has been made. It was concluded that the tectonic fabric of the sample from Auvergne could be interpreted as the result of a mechanical rotation of the composing crystals around two rotation axes, from their earlier orientation which is observed in the German specimen, into their new orientation which is symmetrical in respect of the intersecting slip planes. The rotation axis of olivine proved to be parallel to the intersection of the banding and a slip plane (S1), the rotation axis of enstatite is parallel to the intersection of the second slip planes (S2) and a plane normal to the banding, which is characterized by the X01—Yen girdle in the pre-deformational fabric. The geometry of the observed fabric further suggests that the crystals rotated in opposite sense over supplementary angles around the rotation axes. The distribution of olivine in the intersecting planes as well as the above mentioned rotation were further proved in a second sample from Auvergne on which an axial distribution analysis was carried out. The results of this analysis confirmed the expectations that crystals of a specific orientation are concentrated in intersecting directions in the plane of observation. The lattice orientation of olivine proved to be dominated by an orientation of {010} parallel to S1 and [010] sub-parallel to S2, while the enstatite crystals showed a strong preferred orientation of [001] sub-parallel to S1 and [100] in S2. The comparison of the preferred orientation of the X01 axes in five samples of different mineralogical composition has demonstrated that the preferred orientation of the X01 axes increases with increasing olivine content. All these results point to a tectonic nature of the structure of the ultrabasic inclusions in the lavas of Auvergne. Since the Mg/Fe distribution in the pyroxenes of the nodules suggests that these minerals crystallized at temperatures well above those of magmatic assemblages, it was concluded that the studied specimens are not derived by crystal fractionation from the lavas in which they occur, but are likely to be fragments of the earth’s peridotite shell. The fabric of the type-locality of the lherzolites in the French Pyrenees proved to be secondary and symmetrical in respect of the local Alpine stress field in such a way that the Z axes of both olivine and enstatite are parallel to the major axis of the stress deviator. The interpretation of this tectonic fabric of olivine has been based on the translation mechanism of olivine, described by Chudoba and Frechen (1950). In the last chapter attention has been paid to some recent theories and experiments which all lead to the conclusion that the orientation of crystals during growth, either in a uniaxial stress field or under a temperature gradient, is governed by the lattice of the crystals involved, a conclusion that might be useful for the interpretation of olivine fabrics, for the results of this study suggest that the crystal structure and not the grain shape governs he fabric of many ultrabasic rocks.

    Description: In der obersenonen Mastrichter Tuffkreide finden sich kleine Zähne, die durch ihre glatten Kauflächen und die Furchen an den Seiten des oberen Teiles an Kauplatten von Myliobatis erinneren, einen Rochentypus, der ein an durophage Lebensweise angepasstes Gebiss hat. Niemals findet man aber die für diese Familie so typische langgestreckte Form der Zahnplatten; die Zahnoberfläche hat immer rhombische Form. Dames hat eine ausführliche Beschreibung von diesen Zähnen gegeben, die er für Reste eines Cestracion-artigen Namen Rhombodus Binkhorsti Haies hielt, dem er den gab. Ich möchte hier nur noch einige kurze Bemerkungen hinzufügen. Die Abbildungen (fig. 1) zeigen den typischen rhombenförmigen Umriss der Kaufläche (d). Die durch eine in der Richtung der kurzen Diagonale verlaufende, tiefe Rinne in zwei Hälften geteilte Wurzel hat ebenfalls die Gestalt eines Rhombus (fig. 1, b, e). An der Grenze von Krone und Wurzel findet sich an der einen Seite eine Rinne, an der anderen Seite eine vorspringende Leiste (fig. 1 c). Zusammen mit den verticalen Furchen, mit denen die Seiten versehen sind, hat diese Leiste zur Verbindung der Zähne untereinander zu einem Mahlpflaster gedient. Neben dieser regelmässigen Form, die besonders den grösseren Zähnen eigen ist, fanden sich aber Exemplare, die eine Abweichung zeigen, indem nämlich entweder zwei Seiten eines spitzen Winkels des Rhomboïds länger sind wie die beiden anderen, oder das Rhomboïd unsymmetrisch zusammengepresst ist. Es scheint mir, dass dies nicht eine zufällige Variation ist, sondern dass wir gerade durch diese Eigentümlichkeit etwas mehr über die ganze Zusammenstellung des Gebisses erfahren können. Wie ich unten noch näher auseinandersetzen werden, muss man nämlich Rhombodus zu den durophagen Stachelrochen stellen. Bei diesen findet man sehr oft gerade die grössten Zähne in der Mitte des Kiefers. Wenn man nun die Zahl der Zahnreihen, wie es gewöhnlich bei den grosszähnigen Rochen der Fall ist Rhombodus-Unterkiefers zu 7 bis 9 annimmt, so könnte man das Gebiss eines auf eine Weise rekonstruieren, wie es fig. 3 A zeigt, (wobei die verschiedenen obengenannten Formen vorkommen). Es wäre wohl ein grosser Zufall wenn man noch einige Zähne im ursprünglichen Verband finden würde. Wenn einmal die knorpeligen Kiefer aufgelöst sind, bieten die Seitenfurchen nicht genug Festigkeit und fallen die einzelnen Zähne auseinander.

The following diagnosis, taken from Coker’s description and augmented with a few notes of my own, should validate the name.

    Description: 1. Navarretia squarrosa (Eschsch.) Hook. & Arn. is mentioned here in addition to our last paper on the Netherlands adventitious flora, published in Gorteria 1, no. 10, 1963, p. 113—117. The species was found in 1962 near Joure, prov. Friesland, and was most probably introduced with bird-seed. 2. All Dutch specimens formerly named Erodium chium (Burm. f.) Willd. and E. cygnorum Nees appear to belong to the Australian E. crinitum Carolin. This species was found as an alien near the wool-mills at Tilburg, prov. N. Brabant and along the river Meuse near Meers, Grevenbicht, and Itteren, prov. Limburg. In the last named localities it was most probably introduced from the wool-factories along the Vesdre in Belgium. Differences between E. cygnorum and E. crinitum are discussed.

    Description: The amount of both living and herbarium material of Ericaceae, which has become accessible to the author in and from Malaysia since his various precursory papers on the family have been published, are the reason for this supplement. In Borneo, collecting in the last years has increased considerably in its northern part. In Sarawak, J. A. R. Anderson and E. F. W. Brunig collected a large number of Ericaceae on various mountains, partly not yet previously visited both within the ‘kerangas’ and the mossy forest. In N. Borneo it was Mrs Sheila Collenette who in 1960 climbed Mt Trus Madi, with c. 2620 m altitude the highest peak there next to Mt Kinabalu, and found on it a new species of Rhododendron besides other species, described from and thought to be limited to Mt Kinabalu up to now. Mt Kinabalu was visited again by W. Meijer in the lower part and the eastern shoulder above Kundasan, by Mrs Collenette in 1960 on a new path, the so-called Mesilau East route, and by the R. Society Expedition in 1961 under E. J. H. Corner (together with W. L. Chew and A. Stainton) on a new trail via the eastern shoulder towards the point, where it meets the Mesilau East route at c. 3440 m.

    Description: For a long time, the genus Stixis has been known in the Indian Floras under the name Roydsia, until Pierre monographed it in 1887. Several of Pierre’s species have in the present paper been reduced, leaving Stixis a genus comprising 7 species and 1 subspecies. The genus, which is very uniform, extends from the eastern Himalayas to Hainan and western Malaysia, its centre being in Indo-China.

    Description: While studying the generic delimitation between the New Guinea Sericolea and the Subantarctic genus Aristotelia of the Elaeocarpaceae I got the impression from the descriptions that all but one species of Aristotelia described from Australia would belong to Aceratium. Also in Australia obviously doubts had arisen concerning their proper generic disposition. C. T. White (Kew Bull. 1932: 42) had already reduced his Aristotelia pubescens to Aceratium. Moreover, all Queensland “Aristotelias” I received from Brisbane had been relabelled“ Aceratium”. As unfortunately no material of these species is represented in the Leyden Herbarium, my study is mainly based on material from the Brisbane and Melbourne Herbaria. This study confirmed that only Aristotelia australasica F. v. M. from New South Wales had been described in the proper genus. In the present paper one new species and one new variety are described and one new combination is made in Aceratium, increasing the total of Australian species to five. As a fair amount of material has now become available, amplified descriptions are here presented of all species.

    Description: Dans les flores de MIQUEL, de BOERLAGE, de KOORDERS, dans „Naturliche Pflanzenfamilien” de ENGLER et PRANTL, comme dans „Genera Plantarum” de BENTHAM et HOOKER et dans „l’Index Kewensis”, partout, on trouve le nom de Schoutenia (avec le nom de l’espèce ovata) et comme synonyme Actinophora (fragrans). Ces dernières années la station d’essai de sylviculture dans l’île de Java au contraire a posé en avant le nom d’ Actinophora avec le nom de l’espèce, qui s’y rapporte, fragrans. En général il me semble préférable de ne pas changer sans nécessité les noms généralement usités, surtout pas dans les sciences appliquées et dans la vie pratique. Pour le cas qu’il y ait des raisons graves pour remplacer un nom par un autre, la branche de la science pure qui s’est occupée de ce problème aura soin le plus souvent de publier le changement de nom; si cela ne se fait pas, il serait à souhaiter que quiconque trouve le changement désirable (homme des sciences appliquées ou de la vie pratique) en consulte d’abord la science pure.

    Description: In 1864 an anonymous list of species of the West Indian marine mollusks was published in Denmark. There were only twenty copies printed, seven of which were lost during transportation to the West Indies (CLENCH et al., 1947—1948, p. 23). The author was HENDRIK JOHANNES KREBS (1821—1907), Fig. 117, a Danish apothecary who lived on St. Thomas, Virgin Islands, from 1843 to 1870. Being the owner of a wholesale firm, he travelled throughout the West Indies, which gave him an opportunity to collect shells and plants. His species list was entitled: “The West-Indian Marine Shells with some remarks. A manuscript printed for circulation between collectors.” It was published by W. Laub’s Widow & Chr. Jorgensen, at Nykjöbing, Falster. As this work is very rare, a republication was issued by CLENCH, AGUAYO & TURNER (1947—1948). The republication is preceded by some remarks, and concludes with a portrait of KREBS, a biography and a bibliography. For more data concerning KREBS, reference should be made to this republication.

DU RY at the Indian site Sint Jan II, Curaçao, in March, 1960, include a few specimens of mammals. As was the case with the Indian site Santa Cruz, on Aruba (HOOIJER, 1960), several forms are represented that are no longer extant on the island, although this does not imply that all of them were strictly endemic at the time of formation of the Indian refuse heaps; they may have been imported for food or other purposes. The material dates from 1000—1500 A.D., and is therefore late pre-Columbian. The following forms are present:

    Description: Zwischen der Sierra de San Luis und der Sierra de Cordoba ragt im Süden der Senke des Rio Conlara eine Scholle des alten kristallinen Untergrundes aus den Aufschüttungen der Pampa hervor. Ganz in der gleichen Weise wie die beiden grossen benachbarten Gebirge trägt sie auf ihrer Höhe eine alte Einebnungsfläche über die sich plötzlich ein kleiner Gebirgsstock erhebt, die Sierra del Morro. Schon durch Ave Lallemant und Brackebusch war bekannt, dass sich junge Eruptivgesteine am Aufbau dieses Gebirges beteiligen, das sich bis zu einer Höhe von 1600 m erhebt, während die Abtragungsfläche an seinem Fusse durchschnittlich eine Höhe von 1000 m besitzt. Brackebusch hat auch bereits auf die kraterförmige Gestalt dieses Gebirges aufmerksam gemacht und erkannt, dass der Rand des Kraters grösstenteils aus kristallinen Gesteinen besteht und ebenso wie sein Boden nur an einigen Stellen von Effusivgesteinen durchbrochen wird. Im Jahre 1911 besuchte ich zusammen mit Herrn Pastore in Buenos Aires die Sierra del Morro und letzterer hat das interessante Gebirge, dessen Probleme wir bei unserem dreitägigem Besuch nicht restlos lösen konnten, später noch einem eingehenderen Studium unterworfen und eine geologische Detailkarte im Masstabe 1:25000 aufgenommen. Bei meinen Ausführungen stütze ich mich neben meinen eigenen Aufzeichnungen vor allem auf die Ausführungen und Aufnahmen des Herrn Pastore, von dessen Karte ich hier eine vereinfachte Skizze gebe.

    Description: De uitgestrekte grindafzettingen der Pleistocene Maas-delta vormen het typische plateaukarakter in het Zuid-Limburgsche landschap. In de dalen, die de latere loop der Maas en haar zijrivieren hierin gesneden hebben, komt in de Zuidelijke helft het Senoon aan den dag. Het grinddek van dit z.g. hoofdterras 1) zakt begrijpelijkerwijze langs de dalhellingen naar beneden en vormt een kapvormige bedekking over het Senoon heen. Waar plaatselijk nog resten van Tertiair (Pliocene-mariene zanden) aanwezig zijn, worden deze zoodoende geheel verborgen en is hun aanwezigheid (in dit gedeelte) alleen uit groeven en boringen bekend. Met uitzondering van enkele diepe groeven op het plateau zelf is dus alleen in de dalen het Senoon ontsloten en wordt daar nog op menige plaats door een dikke laag van jongere grind- en lössafzettingen (midden- en laag terras 1) ) bedekt. Ten Noorden van een strook, die ongeveer van Meerssen naar Kunrade loopt, is dit Senoon tot ongeveer 85 meters verzakt. Deze breukrand is door W. C. Klein in kaart gebracht 2). Van het Senoon komen in Zuid-Limburg de volgende 5 typen voor, die naar plaatsnamen genoemd zijn: Maastrichtsch Tufkrijt (= M) Kunrader formatie (=K) Boven-Senoon Gulpensch krjjt (=G) Groenzand van Vaals (=V) Akensch zand (=A) Onder-Senoon Deze benamingen zullen in het vervolg herhaaldelijk aangeduid worden door de hierboven gegeven afkortingen. Nadat eerst eenige geologische overzichtschetsen gepubliceerd waren (Labry, Binkhorst), verscheen in 1911 een nauwkeurige karteering van het te bespreken gebied, door Uhlenbroek verricht; Maastrichter en Kunrader formatie werden door hem met dezelfde letter en kleur aangegeven, Labry had deze daarentegen van elkaar gescheiden gehouden op zijn geologische schetskaart van Zuid-Limburg.

    Description: Bei den zahlreichen Rekonstruktionen der klimatologischen Verhältnisse, die man für das Ende des Palaeozoikums gemacht hat, ist man fast immer von der Kohlenbildung, der Florenverbreitung und den Vereisungserscheinungen ausgegangen. Der marinen Tierwelt hat man bei der Behandlung dieser Fragen meist nur wenig Beachtung geschenkt, zum Teil fand dies seine Erklärung darin, dass uns die marine Fauna am Ende des Palaeozoikums bis vor kurzem noch recht unvollkommen bekannt war. Die Entdeckung reicher permischer Marinfaunen in den letzten Jahrzehnten hat aber unsere Kenntnis von der permischen, marinen Evertebratenfauna nicht nur ganz erheblich erweitert, sondern vor allem gezeigt, dass in den meisten Tiergruppen die Entwicklung ununterbrochen weitergeht und keine Einschnürung oder gar Unterbrechung erleidet, wie man früher so oft geneigt war anzunehmen. Ja selbst eine in ihren Lebensbedingungen so anspruchsvolle Tiergruppe wie die Korallen hat durch die permische Vereisung offenbar ebensowenig wie durch die quartäre eine erhebliche Unterbrechung in ihrer Entwicklung erfahren, nur ihre Verbreitung wurde auf eine etwas schmalere Zone zu beiden Seiten des Aequators eingeschränkt. Die meisten Forscher, die sich mit klimatologischen Fragen am Ende des Palaeozoikums beschäftigt haben, und eine Erklärung für die scheinbar unipolare Vereisung des Perm zu geben versuchten, kommen schliesslich zu der Annahme, dass die Pole zu dieser Zeit eine andere Lage gehabt haben müssen als heute. Man suchte den Südpol gewöhnlich im Centrum des Gebietes aus dem die glazialen Erscheinungen bekannt geworden waren. So nahm Koken 1) den Pol inmitten des indischen Oceans an, zu einer Zeit als die Vereisungserscheinungen aus Südamerika noch nicht bekannt waren und man auch noch nicht mit der Möglichkeit von Kontinentalverschiebungen rechnete. Wegener 2), der die Kontinente der Südhalbkugel zu einer einheitlichen Kontinentalmasse zusammenschiebt, lässt den Pol von der Ostküste Afrikas im Carbon über den Nordrand des antarktischen Kontinentes nach der Südküste Australiens im Perm wandern. Weder die eine noch die andere Annahme lässt sich nun mit dem Vorkommen einer reichen permischen Warmwasserfauna auf Timor, im malayischen Archipel, vereinbaren. Diese Fauna, die durch niederländische und deutsche Expeditionen auf dieser Insel vor dem Weltkriege gesammelt wurde, ist die reichhaltigste permische Marinfauna, die wir überhaupt kennen. Sie müsste bei der Pollage, die Köppen und Wegener für das Perm annehmen, in einer Breite von etwa 45° gelebt haben. Das Vorkommen einer ausgesprochenen Warmwasserfauna in solcher Nähe eines von einer mächtigen Eiskappe bedeckten Pols scheint mir ausgeschlossen. Wir wissen, dass die intensive Kalkabscheidung, wie sie für Riffkorallen, die grossen Foraminiferen mit kompliziertem Skelett und Kalklagen so charakteristisch ist, nur bei beträchtlich hoher Wassertemperatur stattfinden kann. Für die lebenden Riffkorallen beträgt die Minimumtemperatur etwa 20°, aber für die Nummuliten des Alttertiärs ist sie jedenfalls noch höher gewesen, und das Gleiche dürfen wir auch für die Fusulinen des Carbon und Perm annehmen. Zweck der folgenden Zeilen soll nun sein, zu zeigen, dass es sich bei der Permfauna von Timor wirklich um eine Warmwasserfauna handelt und zweitens, dass diese sicher gleichzeitig mit der permischen Vereisung dort gelebt hat. Als Beweis für die erste Behauptung will ich hier eine Tiergruppe herausgreifen, die als besonders feinfühliger Indikator für die Wassertemperatur zu gelten hat, nämlich die Korallen. Die Anthozoenfauna von Timor ist die reichste, die wir bis jetzt aus dem Perm kennen; sie besteht aus Vertretern der Familien der Zaphrentidae, Axophyllidae und der sogenannten Tabulata und ist mindestens ebenso mannigfaltig, wie die karbonische Korallenfauna 1). Wohl sind unter den eigentlichen Korallen koloniebildende Formen ziemlich selten und nur durch de Gattungen Lonsdaleia und Lonsdaleiastraea vertreten, die noch dazu nicht an denselben Fundstellen gefunden wurden wie die übrige Korallenfauna, die nur aus Tabulaten und Einzelkorallen besteht. Aber auch diese war zweifellos eine typische Warmwasserfauna, eine Art Riffauna, wenn es auch im Perm nicht zur Entwicklung mächtiger Korallenriffe sondern nur ausgebreiteter Korallenrasen kam. Auch auf den älteren palaeozoischen Korallenriffen des Devon und Silur spielen die Einzelkorallen eine viel grössere Rolle als auf den lebenden Riffen. Gegenwärtig sind solitäre Korallen, vor allem in der tieferen See, unterhalb der Riffzone, zu Hause, und nur bestimmte Arten kommen als Riffbewohner auch auf den Riffen selbst vor. Im Palaeozoikum und in geringerem Masse auch im Mesozoikum bildeten Einzelkorallen einen wesentlichen Anteil der Riffauna. Wenn auf Timor gewisse Arten von Timorphyllum, Clisiophyllum und Dibunophyllum leicht mit tausenden von Exemplaren gesammelt werden können, so müssen diese Korallen da doch in grossen Mengen gelebt haben, selbst wenn wir annehmen, dass sie an den Fundstellen noch zusammengeschwemmt sind. Vor allem spricht aber die grosse Mannigfaltigkeit der koloniebildenden Tabulaten dafür, dass wir hier mit einer typischen Riffauna zu tun haben. Diese heterogene Gruppe, die auch auf den älteren palaeozoischen Riffen eine so grosse Rolle spielt, ist am Ende des Palaeozoikums nicht im Erlöschen begriffen, wie man immer noch, auch in den neuesten Auflagen von Lehr- und Handbüchern, lesen kann, sondern mit einer Mannigfaltigkeit entwickelt, die der im älteren Palaeozoikum zum mindestens gleichkommt. Zum Teil schliessen sich die Formen eng an ältere Gattungen an wie die Favosites-, Pachyporaund Michelina-Arten, z. T. lassen sie noch Beziehungen zu älteren Gattungen, aber doch eine deutliche Weiterentwicklung in bestimmter Richtung erkennen, wie Pseudofavosites, Heterocoenites, Aulohelia; ein grosser Teil der Formen stellt jedoch ganz neuartige Typen dar, von denen es vorläufig überhaupt noch nicht möglich ist, sie an Bekanntes anzuschliessen, wie z. B. Trachypsammia, Dictyopora, Schizophorites usw. Viele der Arten, besonders der Pachyporen, sind ausgezeichnet durch eine starke Verdickung des Skelettes. So werden z. B. bei vielen dieser Formen die Polypenröhren in der Tiefe ganz mit Skieroplasmamasse aufgefüllt, sodass die Zweige der Stücke im Innern eine ganz dichte Struktur bekommen. Hierdurch wurde den verzweigten Kolonien eine grössere Festigkeit verliehen. Solche Skelettverdickungen sind typische Anpassungserscheinungen an das Leben in stark bewegtem Wasser in der Riffzone, wie sie übrigens nicht nur die Korallen sondern auch die permischen Crinoiden von Timor in vielen Fällen erkennen lassen. Dazu kommt noch, dass wir von der eigentlichen Korallenfauna von Timor bis jetzt nur eine Auslese kennen. Das Material besteht ja an den Hauptfundplätzen nur aus Bruchstücken von verzweigten Kolonien und den langen gewundenen Einzelkorallen, die zusammengeschwemmt und dabei nach der Grösse sortiert wurden. Das vereinzelte Vorkommen von Bruchstücken grosser Favositesund Lonsdaleia-Kolonien lässt uns aber annehmen, dass auf den permischen Korallenrasen, neben Einzelpolypen und verzweigten Stöcken, auch massige Kolonien vorkommen. Die Art der Zusammensetzung dieser jungpalaeozoischen Riffauna dürfte daher von den älteren Riffaunen dieses Zeitalters nur wenig verschieden gewesen sein. Aber nicht allein die Korallen des Perm von Timor deuten darauf hin, dass wir hier mit einer typischen Warmwasserfauna zu tun haben. Das Gleiche ist der Fall mit der so überaus reichen Crinoidenfauna, ein grosser Teil ihrer Arten dokumentiert sich durch die charakteristischen Anpassungen an das Leben in stark bewegtem Wasser als echte Riffbewohner 1). Unter den Brachiopoden gehören die Gattungen Lyttonia und Richthofenia zu den Indikatoren einer Warmwasserfauna, da ihre Verbreitung auf eine aequitoriale Zone beschränkt bleibt, und sie in den brachiopodenreichen Ablagerungen Australiens bereits fehlen. Endlich müssen wir auch, wie schon erwähnt, die Fusulinen zu den Warmwasserbewohnern rechnen. Jungpalaeozoische Fusulinenkalke kommen auf Timor vor, jedoch ist ihr Verband mit den fossilreichen Permschichten noch nicht aufgeklärt. Die Fauna dieser Kalke ist von dem Bearbeiter auf Grund des Vorkommens von Fusulina granum avenae für karbonisch gehalten worden 1), aber diese Art ist neuerdings in Japan gerade zusammen mit Arten der jüngeren permischen Fusulinenfauna gefunden worden, wie Doliolina lepida und Verbeekina Verbeeki; auch auf Sumatra besitzen die Fusulinenkalke aus denen die F. granum avenae zuerst beschrieben wurde, nach neuern Untersuchungen, permisches Alter. Dazu kommt noch, dass Doliolina lepida auf der Timor benachbarten Insel Letti vorkommt, sodass es wohl nur ein Zufall ist, dass diese und andere typische Permformen auf Timor selbst noch nicht nachgewiesen wurden 2).

    Description: The structural geology and metamorphic petrology of the Bosost area in the Valle de Arán (Central Pyrenees) is discussed. The rocks exposed in this area consist of Cambro-Ordovician mica-schists with numerous granite and pegmatite bodies, phyllites and limestones; Silurian slates and schists and Devonian schists and limestones. The major structure dating from the Hercynian orogeny is the Garonne dome with essentially horizontal schistosity. Large steep folds in the Devonian accompanied by axial plane slaty cleavage are folded disharmonically with regard to the Cambro-Ordovician. Both kinds of structures date from the main phase. A second and later phase with N-S foldaxes was accompanied by laminar flow in E-W direction as shown by numerous rotated porphyroblasts. A third and fourth phase of deformation have folds with vertical axial planes in NW-SE and E-W direction. These last three phases are characterized by minor and microfolds only. The method of investigating microstructures mainly with regard to porphyroblasts is discussed first; then its application. This resulted in the establishment of four metamorphic zones: a biotite-zone; a staurolite-andalusite-cordierite-zone; an andalusite-cordierite-zone and a cordierite-sillimanite-zone; in this order with increasing grade. The higher zones have passed through each of the lower grade ones, so that the cordierite-sillimanite-zone has the most complex history. Staurolite is the first aluminium-silicate to crystallize with increasing temperature, than andalusite, cordierite and finally sillimanite. Before sillimanite started to form, staurolite was already unstable; at the beginning of sillimanite crystallization andalusite became unstable. Cale-silicate rocks in the Ordovician limestone in the cordierite-sillimanite-zone contain bytownite, grossularite, diopside and vesuvianite. Granite and pegmatite bodies and sills occur in all the aluminium-silicate bearing zones, but most abundant in the cordierite-sillimanite-zone. Their emplacement lasted from shortly after the first phase until after the fourth. The culminating point lies around the fourth phase. The granites are mainly composed of albite, quartz, and muscovite; the pegmatites carry smaller or larger amounts of microcline. Chemical analyses of phyllites and mica-schists have shown that the composition of both rock groups is essentially the same. With increasing silicium content, aluminium and potassium decrease. The granites have high alcali percentages with sodium predominating over potassium.

    Description: Von der „Bataafschen Petroleum Maatschappij” erhielt das Leidener Museum eine reichhaltige Sammlung von Fossilien, die durch die Herren Ganz, Gsell u. Freylink in der Umgebung von Payta gesammelt worden waren. Die Fauna ist dadurch besondere interessant, dass sie einen ganz neuartigen Charakter besitzt, der von dem der bis jetzt aus Südamerika bekannten oberen Kreide stark abweicht. Da sich die endgültige Bearbeitung des umfangreichen Materials noch etwas verzögern wird, möchte ich das Vorkommen und seine Fossilführung kurz schildern, vor allem aber die neue Pironaea-Art beschreiben, da das Auftreten dieser interessanten Gattung in Südamerika von besonderer Bedeutung ist, zumal es sich um den ersten Hippurit handelt, der aus diesem Kontinent bekannt wird. Die obere Kreide tritt in der Umgebung von Payta in zwei getrennten Gebieten auf. Das eine befindet sich am Westabhang der Sa. de Amotape. Die Kreide wurde dort zuerst von Bravo 1) aufgefunden und neuerdings von Iddings und Olsson 2) gegliedert. Bei Pan de Azucar und El Muerto liegen schollenförmige Erosionsreste diskordant auf jungpalaeozoischen Schichten, die die ersten Erhebungen der Sa. de Amotape aufbauen. Ein vollständigeres Profil ist im Oberlauf der Quebrada Parinas aufgeschlossen, wo die Kreideschichten in einer grabenförmigen Senke tiefer in das Gebirge eingreifen. Iddings und Olsson unterscheiden von oben nach unten:

    Description: In their classical studies on the Alpine glaciation Penck and Brückner gave a small blockdiagram to illustrate the arrangement and shape of the deposits at the lower end of a former glacier: the fluvioglacial series. This diagram has been reproduced in so many text-books, that it may be worth-while pointing out a fault in its construction. The case represented by the authors is that of two terminal amphitheatres lying within eachother (fig. 1) 1). The manner in which the outer moraine with its fluvio-glacial fan of sediments is drawn in on top of the inner moraine proves it to be the younger of the two. In this case the glacier must have ridden over the inner circle, thereby destroying its ridge; but in the drawing this ridge is represented as having been left perfectly intact. On the glacier receding again the material of the older moraine would be found buried under the newer deposits, and only one frontal moraine would be left (fig. 2, A).

    Description: Die Subsubclassis Redioinei ODENING, 1960 innerhalb der Unterklasse Digenea (VAN BENEDEN, 1858) wurde in zwei früheren programmatischen Systementwürfen provisorisch, teilweise in Anlehnung an LA RUE (1957), gegliedert (ODENING 1960, 1961b). Ich halte es heute für angebracht, die in jeder Beziehung bestimmbaren und festumrissenen Trematodengruppen als Ordnungen zu bewerten, wie es z.B. auch in den neueren Systemen der Cestoden der Fall ist. Diese Auffassung hat nicht nur praktische Vorzüge, sondern sie befreit auch die unbestritten einheitlichen Gruppen aus hypothetischen Verbindungen. Ist es doch ein Nachteil der meisten neueren Einteilungsversuche der Digenea, daß phylogenetische Hypothesen in Form von Ordnungen etabliert wurden, die nach Lage der Dinge je nach Auffassung der Autoren recht verschieden zusammengesetzt waren, während die wirklich einheitlichen Gruppen mit den Zwischenkategorien (Unterordnung, Überfamilie) bedacht wurden. Die Redioinei umfassen nach der neuen Wertung folgende selbständige Ordnungen (alphabetische Reihenfolge): 1. Allocreadiida Odening, 1960 2. Azygiida (La Rue, 1957) stat. et nom. emend. 3. Clinostomatida (Allison, 1943) stat. et nom. emend. 4. Cyclocoelida (La Rue, 1957) stat. et nom. emend. 5. Fasciolida (Poche, 1926) stat. et char. emend. 6. Hemiurida (Poche, 1926) stat. emend. 7. Opisthorchiida (La Rue, 1957) char. emend. 8. Paramphistomatida (Poche, 1926) stat. et char. emend. Die Ordnung Didymozoida (Poche, 1926) ist von den Redioinei auszuschließen, da sie möglicherweise nicht zu den Digenea gehört (siehe Baer & Joyeux 1961).

    Description: When working at the Tropical Institute, Amsterdam (1952—1957), some cases came to my notice of small borers belonging to the Scolytidae, Platypodidae and Bostrychidae attacking newly felled timber in Surinam and causing the same well-known trouble as in other tropical regions. My interest in the neotropical representatives of these families was further aroused by the material handed to me by my friend J. G. Betrem who had collected it during the two months that he carried on investigations into the status of Xyleborus morigerus in coffee plantations near Cali, Colombia, in 1959. This led me to assembling and assorting the material of these families of West Indian origin to be found in the collections of the Leiden and Amsterdam museums. This material was rather scanty and partly unnamed but it still provided some interesting data. Recently Mr. P. H. van Doesburg jr, entomologist at the Landbouwproefstation (Agricultural Experiment Station) at Paramaribo submitted some newly acquired Scolytidae which he had collected in the Surinam plantations. They provided some data on the habits and economic status of the little borers additional to those compiled by J. B. M. van Dinther in his book on the Insect pests of cultivated plants in Surinam (1960), in which survey a few species collected by him but not fully identified, were mentioned. At my request I then received for examination the latter specimens kept in the collection of the Entomological Laboratory at Wageningen, and, through the kind cooperation of Dr. D. C. Geyskes and Mr. van Doesburg, also all the material preserved in the collections of the Surinam Museum and the Experiment Station at Paramaribo. My main interest was directed towards the ecological data and a search was made for information to be found in earlier reports and in the literature of adjacent countries. In this way sufficient relevant data accumulated to warrant the publication of the present paper. For the identification of species unknown to us and the verification of old names I applied to Professor S. L. Wood, Provo, Utah, U.S.A. on various occasions. A few Bostrychidae were identified by the late Professor J. M. Vrijdagh, Brussels.

    Description: This thesis describes the vegetation and discusses the prevailing ecological factors of a savanna region near Jodensavanne, Suriname; savanna being defined in this context as a landscape with low and often open woody vegetation, relieved by tracts with a thin to dense cover of herbs. The methodology of the French-Swiss school of phytosociologists appeared appropriate for semi-quantitative description of the vegetation but, because of the limited scope of the study, it was considered premature to apply the synsystematic rules of this school, so the established units are called “major vegetation types”, with “variants”, “subvariants” and “facies” as subunits. Three major vegetation types of scrub and five of herb vegetation are described in detail and some attention has been given to the surrounding woods and forests. Except for small fringe areas, the savanna is limited to rather coarse white-sandy soils, the characteristics and genesis of which are discussed. It is demonstrated that the hardpan which occurs in places is a paleopedogenelic feature and that this hardpan does not influence the presentday drainage conditions, for the drainage pattern could be explained on the basis of topography alone. The drainage condition which is one of the more important edaphic factors affecting the vegetation, allows a division of the vegetation types into two groups, one representing the “dry savanna” and the other the “wet savanna”. On the wet savanna much of the differentiation in the herb vegetation is produced by water flowing over the soil. Some direct results of burning could be analyzed, but about the long term effects of fire only suppositions could be made.

    Description: The Kwae Noi River basin, WNW of Bangkok, close by the forested Bilauk Taung range along the frontier with Burma, has again attracted the attention of botanists. In 1926, Kerr collected c. 558 numbers; in 1946, Kostermans, Bloembergen & Den Hoed over 1200. From 1 November 1961 to 24 February 1962, an exploration in this area was made by Mr. Kai Larsen of Copenhagen and Mr. Tem Smitinand of Bangkok. They collected in various forest types, also on limestone and in swamp vegetations, about 2000 numbers. The material is at the Copenhagen Museum, the second set, after identification, will go to Bangkok; duplicates are available to the institutes where specialists assist in the identification and as exchange material. In Mr. Larsen’s brief account, Nat. Hist. Bull. Siam Soc. 20 (1962) 109-119 + map + 9 phot., we are pleased to read that the Erawan area, with its travertine formations and rich fern vegetation, is planned by the Royal forest Department to be safeguarded as a national park.

    Description: Walker, F.S.: The forests of the British Solomon Islands Protectorate. A new printing of this book, which never received a very wide distribution, appeared in 1962. It gives a general description of the vegetation, based on 18 months of survey and detailed notes on about 300 species collected by Walker and C.T. White. Useful for both botanist and forester. Copies cost Austr. £ 2.- (i.e. about 34 Sh. Sterling or US $ 4.50); enquiries should be addressed to the Chief Forestry Officer, P.O. Box 6, Honiara, British Solomon Islands. Mr. K. M. Kochummen of the Kepong Forest Research Institute has prepared field keys for all Malayan timber species mentioned in the Pocket Check List. The intention is to produce an enlarged revised edition (the present issue being out of print), but it is probable that the data will come out in the Forest Research Pamphlet series first.

    Description: Abstracts of papers presented at the meetings of the Botanical Society of America, in Am. J. Bot. 49 (1962), as far as these relate to Malaysian botany. Author’s addresses are found in the Journal. Canright, J.E. & M.P. Paden: Contributions of pollen morphology to the phylogeny of the Annonaceae, Eupomatiaceae, and Myristicaceae: p. 674. -— Palynological evidence supports Sinclair’s view that Desmos and Dasymaschalon should be merged. The African genera Isolona and Monodora, however, should probably be placed wider apart as their grouping together in the Monodoroideae seems unnatural. Palynologically as well as anatomically, Eupomatia is suspected not to link Annonaceae with Eupomatiaceae as Hutchinson suggested. Relationship of Myristicaceae with Annonaceae is confirmed.

    Description: More than ten years ago, I published some notes on the taxonomy of Surinam millipedes. My intention then was to describe and record in a series of papers the material of Diplopoda in the collections of the Amsterdam and Leiden Museums, and to give a survey of the millipede fauna of Surinam. However, as this work progressed it became evident that the monographs and revisions by the authors of the previous generation were only too often a quite unreliable basis for the project planned, and that descriptions of new species were rather useless if not preceded by at least partial revisions of the nomenclature and systematics of the genera or even families involved.

    Description: Among the fishes taken during a recent collecting trip to Curaçao are three very colorful small serranoids which represent undescribed species. Two of the three new fishes are grammids of the previously monotypic genus Lipogramma, and their discovery necessitates a slight modification of the generic description. The remaining fish is provisionally placed in Chorististium (this genus may not be distinct from Liopropoma). Five other small serranids and one grammistid not known from Curaçao were also collected: Chorististium rubre, and C. mowbrayi, Serranus annularis, S. luciopercanus, Schultzea beta Pseudogramma bermudensis. Four of these fishes have also been taken in Puerto Rico for the first time and two of the new species as well. The holotype of each new species has been deposited in the United States National Museum (USNM). Paratypes have been variously placed in the U.S. National Museum, Academy of Natural Sciences of Philadelphia (ANSP), Marine Laboratory of the University of Miami (UMML), Rijksmuseum van Natuurlijke Historie at Leiden (RMNH) and the University of Puerto Rico at Mayagüez (UPR).

    Description: Bij het zoeken naar een terrein, waar zoowel stratigrafisch als petrografisch gewerkt zou kunnen worden, viel het oog op de omgeving van het Brembodal. Hiervan bewerkte ik een gedeelte tusschen Caprile en Lenna met als W. grens de waterscheiding over de Pizzo di Mezzodi en Chiappa naar de Disner en de Pizzo di Cusio. In het N. vormde een E.—W. lijn door Caprile sup. naar Sparavera de grens, in het S. het Valle di Lenna en de Brembo, terwijl aan den E. kant als grens werd genomen een lijn van Mojo di Calvi naar Piazzatorre. Ten N.W. hiervan werd gewerkt door den Heer Jong, wiens publicatie binnenkort zal verschijnen, terwijl de Heer Klompé bezig is met de karteering van het gedeelte ten N. van de lijn Caprile—Sparavera. Het veldwerk werd verricht in het voorjaar en in den zomer van de jaren 1926 en 1927. Het verzamelde materiaal, dat ik in het Geologisch Museum te Leiden onderzocht, zal aldaar worden opgeborgen.

    Description: During an excursion to the South of Switserland, Professor Escher suggested my mapping out the south-western corner of the porphyry district of Lugano. I gladly agreed, for his detailed examination of the Morcote-peninsula had already shown that many interesting facts had escaped unobserved during the small-scale mapping forty years ago; and it was, therefore, highly probable that the projected work would prove fruitful. The necessary field-work was carried out in the spring of the years 1924 and 1925. The collected material I examined in the geological museum of Leiden, where it will remain in future.
