Description: Zeer geachte Toehoorderessen en Toehoorders, Bij het beginnen van een wetenschappelijk onderzoek zal meestal degene die zich daaraan gezet heeft, allereerst het antwoord dienen te vinden op enkele fundamentele vragen. Zijn deze primaire vragen beantwoord, dan is de weg gebaand voor verder onderzoek en voor algemene theoretische beschouwingen. Deze fundamentele vragen zijn echter niet voor elke onderzoeker en ook niet voor elk onderzoek in een zelfde tak van wetenschap steeds gelijk. Dit hangt af van vele factoren, zoals: uiteindelijk doel van de studie, aard van het materiaal, geaardheid vooral van de onderzoeker, enz. Vandaag wil ik met U behandelen de hoofdvragen, die zich bij mij, voor de aan mij toevertrouwde onderdelen van de botanie steeds op de voorgrond plaatsen en de wijze waarop ik die beantwoorden pleeg te interpreteren voor het verdere onderzoek. Hierdoor zal ik tevens de gelegenheid hebben, om aan te stippen in welke richting wij op het gebied van de bijzondere plantkunde en de plantengeografie nog onderzoekingen kunnen verrichten, die ons inzicht in het geheel aanmerkelijk kunnen verruimen. Voor ik met mijn eigenlijke onderwerp begin, moet ik toch iets zeggen over wat „bijzondere plantkunde” is. Ik zal er niet te veel over uitweiden, daar, zoals Koningsberger en Reinders in het voorwoord van het eerste deel van het Leerboek der Algemeene Plantkunde terecht opmerken, de scheiding tussen „algemene” en „bijzondere” plantkunde uiteraard onscherp is. Volgens de letter van de gebruikelijke terminologie zou eigenlijk alles wat niet „algemeen” is thuis horen onder de bijzondere plantkunde. Zover wil ik niet gaan, want dat zou mijn taak wel heel omvangrijk maken en afgezien van het feit dat het buiten mijn kunnen zou komen te vallen, denk ik ook dat mijn collega voor de algemene plantkunde ernstige bezwaren zou maken indien ik datgene van de plantenphysiologie dat zeker niet algemeen is te noemen, voor mijzelf zou gaan opeisen. Ik wil daarom beginnen de physiologie, hoe bijzonder deze hier en daar ook moge zijn, maar onmiddellijk in zijn geheel bij de algemene plantkunde te plaatsen. Voor de rest zou ik mijn bovengenoemde definitie, dus „bijzonder” is alles wat niet „algemeen” is, in grote trekken willen volgen, met dien verstande dat ik mij natuurlijk wil houden aan de veelal gebruikelijke taakverdeling, zodat b.v. de „algemene” morphologie en anatomie van de Angiospermen, die in feite in het plantenrijk als geheel, „bijzonder” is, bij de „algemene plantkunde” wordt ondergebracht. De speciale en vergelijkende morphologie van deze groep reken ik echter zeer zeker tot de mij toegewezen tak van wetenschap. Ook de afgrenzing met de genetica is niet scherp. Indien men elk onderzoek waarbij niet uitsluitend op het phaenotype maar ook op het genotype gelet wordt, tot de genetica wil rekenen, dan zal de betrekkelijk jonge experimentele plantensystematiek of biosystematiek geen deel kunnen uitmaken van de bijzondere plantkunde. De genetici zullen het mij wel niet euvel duiden, dat ik ook deze tak van onderzoek laat staan bij de bijzondere plantkunde, waaruit zij is voortgekomen en waarvoor zij van zoveel betekenis is.

Description: Dames en Heren, In een universitair blad kwam onlangs de mededeling voor, dat aan een hoogleraar, die zich in dezelfde moeilijkheid bevindt als ik, nl. dat hij in de loop van deze cursus 70 jaar is geworden, een afscheidscollege zou worden aangeboden. Ik vond dat een sympathiek plan. Als men met college geven, ondanks de daaraan verbonden bezwaren, de 70-jarige leeftijd heeft gehaald, is het werkelijk geen overbodige weelde dat een ander de taak voor deze laatste keer van hem overneemt.

Description: What KIAERSK wrote in 1893 in the preface of his “Enumeratio Myrtacearum Brasiliensium” is still largely valid. It is often most difficult to define a species belonging to this family, not only because, in the absence of ripe seeds, the genus is not easily ascertainable, but also because of the strong variability shown by the vegetative characters. Thanks to the examination of the rich Guiana material preserved in the herbaria of Genève, Kew, Leiden, New York, Paris and Utrecht, I have usually been able to delimit the species in a satisfactory way; their allocation to a definite genus, however, is often a difficult problem. During the preliminary stage of this investigation, which was interrupted by the war, it was of great advantage to me that I could study the Guiana specimens of the Leiden herbarium. In order to avoid misinterpretations, I have tried to base my conclusions as far as possible on an examination of either the types themselves or of duplicates of the latter. Several of these types, especially those that form part of the earlier collections of Guiana plants, e.g. of the collection Aublet, and of the collections Desfontaines (herb. Florence) and De Candolle (Genève) had never before been reexamined, and BERG, the last monographer of the South American Myrtaceae (in Linnaea XXVII (1855—56), XXIX (1858) and XXX (1861) has either neglected these species or given an, often incorrect, interpretation based on the description alone. For this reason the second part of this paper will be devoted to a short survey of these earlier types. My best thanks are due to the directors of all herbaria mentioned. Moreover, I have to thank the “Van Eedenfonds”, whose financial aid enabled me to pay a visit to Kew and to the British Museum.

Description: Among the material collected by LANJOUW and LINDEMAN during the Suriname Expedition 1948—’49 a specimen of Mabea taquari Aubl. was found whose flowers showed some interesting deviations from the normal structure. In the “Flora of Suriname” vol. II, part 1 (1932), p. 78 LANJOUW states that the female flower of the genus Mabea Aubl. is apetalous and provided with a 5- or 6- partite calyx. In a re-investigation of the specimens preserved in the Utrecht Herbarium this could as a rule be confirmed.

Description: Dr J. Hutchinson retired after 44 years of service in the Royal Botanic Gardens at Kew (May 31, 1948), as Keeper of the Museum. He will devote his time mainly to the writing of some general handbooks especially his Genera Plantarum. He was succeeded by F.N. Howes, D. Sc. Mr H.K. Airy Shaw was appointed Principal Scientific Officer, Royal Botanic Gardens, Kew, on Dec. 31st, 1948.

Description: A growing interest in the Flora Malesiana was a chief characteristic of 1950. The number of free subscriptions increased to over 320 and the total of subscriptions, therefore, to over 620 as the Government of Indonesia receives 300 copies for official purposes. The first volume of series I, the Cyclopaedia of Botanical Exploration in Malaysia, which contains the main bibliographical and biographical data of all collectors in Malaysia, accompanied when advisable by an itinerary and information concerning the collections, has now been printed. It is expected that the volume will appear before the end of the year thus bringing Mrs.M.J. van Steenis-Kruseman’s patient and devoted work during more than 12 years to a conclusion.

Description: It is advised to address all mail with destination Royal Botanic Gardens, Buitenzorg, in future as ’Royal Botanic Gardens, Bogor (Buitenzorg)’ The present number, Flora Malesiana Bulletin No. 6, concluded the 1st volume. The second volume of the Flora Malesiana Bulletin begins with no. 7.

Description: The vegetative characters — especially those which are important for identification of the species — together with the distribution of the Polysiphonia species occurring in Netherland’s waters were subject of the following study. The material used consisted for the greater part of dried specimens, present in the following collections: Rijksherbarium (Leiden), herbarium Van Goor, Zoological Station (Den Helder), herbarium of the “Koninklijke Nederlandse. Botanische Vereniging” (Rijksherbarium, Leiden) and the herbaria of the Universities of Amsterdam, Groningen and Utrecht.

Description: This paper on the Philippine species of Argyreia forms an addition to that published by the same author in Blumea V, 2, (1943) p. 352—383. As to the description of the genus, the limitation of it against Rivea and the inclusion in it of Lettsomia may be referred to what has been said on p. 353—356 of that publication.

Description: In the course of my study on the wood-anatomy of Javan woods (Mikrographie des Holzes der auf Java vorkommenden Baumarten), I examined also many woods from mangrove-trees. Mangrove has been the subject of much investigation; the community is usually described as xeromorphic. Mangrove woods proved to be different from woods belonging to species growing in other stations even if those species belonged to the same family or even genus. The data may be traced in my “Mikrographie” but it seems more convenient to review them here.

Description: The numbers (St. ...) quoted in the present systematic part, are the registration numbers of specimens in the Geological Museum at Leiden. The molluscan collection from Poeloe Boenjoe comprises the numbers St. 41757—’61 (inclusive), ’63—’70, ’73—’97, ’99—41802, ’04—’09; Tarakan: St. 41742—’50, ’98. Other organisms: Boenjoe: St. 41762, ’71, ’72, ’95, 41803; Tarakan: St. 41751, ’52, ’53, ’54, ’55.

Description: In the collections of the Leyden Geological Museum is a set of fossiliferous clay-stones which was long ago collected by the mining engineer Hulshoff-Pol in the coal quarries of Batoe Panggal 1), Eastern Borneo. He presented the collection in 1902 to Dr M. Schmidt, who at that time was making geological investigations in Borneo. After Dr Schmidt’s appointment to a professorship in Stuttgart, the fossil collections made by him in Borneo were acquired by the Leyden Geological Museum (1920). Fig. 1 roughly indicates the locality of Batoe Panggal, while Fig. 2 depicts the delta area of the Mahakkam or Koetei river and its neighbouring areas. The dotted area is again represented in Fig. 3 below.

Description: 1. This paper deals with a pollenanalytical investigation of holocenic peat-layers in Central Friesland. 2. One diagram shows a praeboreal spectrum with Betula in the dominant position, the first appearance of thermophilous trees (Corylus, Alnus) and a high percentage of Gramineous and Cyperaceous pollen. 3. Originally in all diagrams the percentages of Ericaceous pollen are low. 4. During the boreal time the peat formation was of little importance. A maximum of Corylus pollen in the boreal period has not been found here. 5. In the Atlanticum a thick layer of peat has been formed; the percentage of Alnus pollen remains high, the Quercetum-mixtum fluctuates between 10 and 25 per cent and there is also much Corylus pollen. 6. Two narrow clay-bands are present in the peat. They contain many pollen grains of halophytic plants, which indicates that there must have been two marine transgressions in the Atlanticum. These transgressions will have reached their farthest point in this region. 7. In the upper atlantic and subboreal peat-layers there are many fragments of Ericaceae and also a high percentage of Ericaceous pollen. 8. The Young Sphagnum peat consists of Sphagnum species of the Cymbifolia section. The presence of Fagus pollen never reaches a level of 10 per cent. 9. During the subatlantic transgression the Young Sphagnum peat has locally been washed away and was replaced by clay with many Phragmites rests. The author wishes to express his thanks to “It Fryske Gea”, the Frisian association for the protection of nature, president Mr. M. WIEGERSMA, Drachten, for the permission to take samples at “Het Princehof” and for the assistance to this work. He is also highly indebted to Dr. F. P. JONKER for his assistance and interest during the investigation and to Prof. Dr. C. E. B. BREMEKAMP for correcting the English text.

Description: Blume, C. L, Bijdragen tot de kennis van de Flora van Nederlandsch Indië. Reprint of part 4 ( 1850). Dr M. A. DONK draws attention to the fact that part 4 of BLUME’ s Bijdragen was reprinted in 1850, at Batavia. The printers were VAN LANGE & Co, not the Landsdrukkerij this time. A copy of this second edition is in the Bibliotheca at Bogor. The letterprint is different from that of the original and the paper is of inferior quality. The numbering of the pages is kept as much as possible in agreement with the original edition. At Bogor there is an other copy of the Bijdragen in which part 4 is in MS,; this indicates that at some time no stock was available of the original edition.

Description: In the following the abbreviation B.Z. means ’Binnenlandsche Zaken’ or ’Ministry for the Interior’; all records referred to are preserved in the National Archives (’Rijksarchief’) at The Hague. By Royal Decree of Febr. 10, 1839, no. 101 (cf. B.Z., 5th Div., Febr. 18th, 1839, no 132) it was decided to publish a printed work at the expense of the Government. The issue was to consist of 250 copies and each of the planned 3 volumes were to contain c. 400 pp., 60 (coloured) plates and quarterly instalments were to be published. The costs were to be deducted from the funds granted to the ’Natuurkundige Commissie’ (Board for the Naturel Sciences) who had explored in the Dutch East Indies since the withdrawal of the English (1816). The work should embody the scientific results of the ’Commissie.’

Description: The death of Cyril Tenison White, Government Botanist, Brisbane, Queensland, occurred on August 16, 1950.; The news came suddenly and hit hard; we lost one of the kindest and gentlest of men and, besides, the greatest living authority on the Papuan and Melanesian flora. Mr White had been seriously ill, two years ago, but seemed to have recovered. His heart remained weak, however, and though he seemed in good health, he had to desist from mountain climbing.

Description: Koorders, Fl. v. Tjibodas 2 (1923) 32—46; Hochreutiner in Candollea 2 (1924—1926) 336—359; Ochse, Indische Groenten (1931) 719—722; Backer, Onkruidfl. Java Suiker (1930) 203—209; Aimshoff in Blumea 5 (1942—1945) 515—517. Miss Dr G. J. Amshoff started the revision of the Javanese Urticaceae, but left the definitive preparation to me. Urtica dioica L. and U. urens L. have been erroneously recorded for Java (Miquel, Fl. Ind. bat. 1², 1859, 227; Koorders, Exk. Fl. Java 2, 1912, 126). To my knowledge no specimens were ever collected there nor elsewhere in the Malay Archipelago.

Description: Little attention has been paid till now to the algae, transported to the Netherlands coast on drifting objects. About a century ago T. D. Vrijdag Zijnen and G. Bisschop (near Scheveningen, ± 1845), and L. H. Buse (between Wijk aan Zee and Zandvoort, ± 1840—1847) were the first to pay attention to this subject. The material collected, especially that by the first two investigators, is mentioned in the Prodromus Fl. Bat. (1853). The book of Van Goor (1923) contains a chapter on these algae, in which, however, only few new observations occur. The author is much indebted to Dr Josephine Th. Koster for her kind help, as well as to Dr S. J. v. Ooststroom. The material, collected by Vrijdag Zijnen, Bisschop and Buse is almost completely present in the collections of the ‘Rijksherbarium’ and the ‘Koninklijke Ncderlandse Botanische Vereniging’, Leiden. The material, collected during the last few years has for the greater part been brought together by the present author, and furthermore especially by K. Swennen (Den Helder), J. Stock (Amsterdam), A. Mulder (Haarlem) and P. Leenhouts (Scheveningen). This material belongs to the collection of the Rijksherbarium, Leiden, but most of it is, for the time being, put under the charge of the “Comité ter Bestudering van de Nederlandse Mariene Flora en Fauna” (“Committee on the Netherlands’ Marine Flora and Fauna”) and temporarily preserved in “Het Filiaal”, Leiden.

Description: During the long years I was engaged in writing my “Mikrographie” (1), my main purpose was to give a survey of the wood-anatomy of as many representatives of the javanesc wood flora as I could lay hands on, in connection with Koorders’ and Valeton’s “Bijdragen” (2). My attention being almost exclusively absorbed by the descriptive side of my task, little attention was paid to eventual conclusions regarding family relationships, though some were incidentally pointed out. When this work of long years was completed, the need of a key for the identification of wood samples was felt. This I composed and completed just before the war. It was published in 1940 and written in German (3), as was the main work on which it was based. Immediately an English translation was prepared but though this was ready for the press as early as 1942, I was prevented from publishing it, at first because of the German occupation and later on for want of funds.

Description: It is a pleasant duty to announce a work to which all students of the Malaysian Flora, and I am sure, many others, have been looking forward for some time; the first issue of, it is hoped, a very long and continuous series which will ultimately lead to a complete flora of the Malaysian region, including British Malaya, the Philippines and New Guinea which, floristically speaking, forms a natural unit. The work, written in English under the auspices of the Royal Botanic Garden, Buitenzorg (now Bogor), Java, is the result of the painstaking efforts of its Editor-in-Chief, the well-known Buitenzorg botanist, Dr C. G. G. J. van Steenis. Generously supported by his wife in many respects, he has, and under the most difficult circumstances, indefatigably fought to get this extensive project started. Not ony he, but the Indonesian Government as well, are to be congratulated on the result of their efforts. It deserves our sincere and warm appreciation that the Government of this young country has understood its responsibilities and is backing the work with considerable interest, both morally and financially.

Description: The present paper deals with a small collection of Neogene fossils which has been made by the geologist Dr. M. Schmidt in the Sangkoelirang area 1), East Borneo. The locality is defined in Gerth’s (1923) and Krijnen’s papers (1931, loc. no. 175, p. 535). It must be stated here that this locality has been mentioned incorrectly in literature, viz., as “Hill near Sekoerau” instead of “Coral limestone, Hill near Sekoerau”. Dr. Schmidt’s collection, which was sold to the Leyden Geological Museum in 1920 — about twenty years after being made — contains two different faunas from Sekoerau: vide infra.

Description: De moeilijkheden, die optreden bij het determineren van de Nederlandse vertegenwoordigers van het genus Centaunum (= Erythraea), waren voor mij aanleiding het Nederlandse materiaal eens aan een revisie te onderwerpen. De Franse flora’s b.v. vermelden een aantal soorten, waarvan het voorkomen in Nederland niet onmogelijk is (lit. 1, 2, 9). De bewerkingen van het Britse materiaal door WHELDON and SALMON in 1925 (lit. 15) en door GILMOUR in 1937 (lit. 4) wezen uit, dat ook in Engeland tal van soorten en variëteiten voorkomen, die voor Nederland onbekend zijn. Tenslotte verscheen in 1940 een bewerking van het Scandinavische materiaal van C. vulgare door STERNER (lit. 12), waarbij eveneens tal van vormen voor de dag kwamen en ook een voor Nederland onbekende soort. De Zweed WITTROCK heeft zich het meest intensief met het genus bezig gehouden. Hij gaf een aantal exsiccaten uit onder de naam „Erythraeae exsiccatae” en was van plan een monografie van het genus te publiceren. Dit laatste is door zijn dood in 1914 verhinderd, zodat we van zijn resultaten niets anders weten dan het gepubliceerde in enkele referaten (lit. 16) en de niet geldig gepubliceerde manuscriptnamen van de exsiccatae. WITTROCK’s exsiccaten zijn in de Nederlandse herbaria niet aanwezig.

Description: On request of the Army, several voluminous bibliographies nave been published in Japan during the war. Advanced scientists accomplished the work in collaboration with teams of students by using Japanese libraries. The first of these bibliographies appeared in 1942, the last in 1944. They were apparently already planned before the war and intended to form one of the sources of information for the Intelligence Service. They were published under the general title ’Bibliographic Index for the study of the natural resources of the Great Asia co-prosperity sphere’ and compiled by the Department of Education, Dai Nippon.

Description: The second instalment of the Flora Malesiana was published in December 1949. It contains pp. xli – clxi ana 41-140, and c. 160 illustrations. The total issue is fixed at 1000 copies of each instalment. At the present moment more than 550 subscriptions have been received. It seems that the future of Flora Malesiana is assured. The second instalment of volume 4 contains the final part of the ’General Considerations’, by the general editor, ’A short history of Malaysian phytography’, by Dr H.C.D. de Wit, and revisions of Malaysian, plant families by Dr C.A. Backer, Dr P. Buwalda. and by Dr C.G.G.J. van Steenis.

Description: This is, I believe, the most important single contribution in the field of Hymenomycetes for years. The author was attracted to the group commonly known as Clavariaceae as early as 1925 when in England; he continued his studies when working on the staff at the Singapore Botanic Gardens and after his return to England. He got the conviction that before science could undertake a wholesale revision of the present classification of Hymenomycetes, the larger constituent groups should be worked over, one at a time, and ‘their particular kind of fruit-body described in terms of hyphal properties’, and that to omit the tropical element would mean certain failure. Thus, the aims of this admirable volume become clear: a large number of species of “Clavariaceae“ are described in an exemplary manner as to their hyphal structure after the living state, and about all that is known about the group and its species was compiled so that the often quite inadequate tropical library has to a large extent become superfluous. This is one of the rare occasions on which we find that an author’s field knowledge of a group is based rather on tropical than on European or North American materials The author combines with an exceptional tropical field experience, the insight of an agile mind and a great artistic skill for drawing. It might be regretted that he neglected the many and scattered poor specimens in the European and American herbaria that served as a basis for the already described species, but it is fair to point out that, as stated, this side was not his primary object and that it is unreasonable to ask for everything. The result is an imposing book that will serve as an absolutely indispensable guide for every future student of the group. We hope that it will be extensively used by collectors in the tropics, who now can pay attention to a group about which they can instruct themselves at their own will and according to their needs..

Description: As long ago as 1926-27, during my last two years at Utrecht University, when studying the taxonomy and distribution of the Malaysian Bignoniaceae (Thesis 1927), I felt the need for a reference work in localizing inadequately labelled specimens. Material collected in the 19th century, especially that of BLUME, KORTHALS, JUNGHUHN, ZIPELIUS,¹ MOTLEY, HORSFIELD, etc. bear scant notes. Either these collectors did not realize the future value of full data or their notes were not mounted on the sheets in the herbarium and were often subsequently lost. I have also observed a tendency in some authors of tropical plant species in that period to underrate the importance of the locality because of their belief that tropical plants occurred everywhere in the tropics, i.e. were ubiquitous in the plant-geographical sense. Sometimes the collectors were natives accompanying expeditions, who did not make notes, e.g. JAHERI, ACHMAD, etc. Hence, it is often very difficult to trace the exact origin of specimens. KORTHALS’S plants, for example, are mostly labelled merely: ‘Borneo’. This botanist, however, described the parts of Borneo in which he collected and an extensive printed record of his travels is in existence.

Description: Though the new names published in Thunberg’s “Florida” have been entered in the Index Kewensis, few botanists have tried to verify the status and synonymy of the new species proposed in this 2-thesis booklet. Thunberg’s names were entered in Juel’s “Plantae Thunbergianae” (1918, 412 pp.). The diagnoses are generally too short and vague to allow a definite opinion. Only Schott, Mueller Arg., and F. E. Wimmer have examined material of resp. the Araceae, Euphorbiaceae, Campanulaceae.

Description: This paper presents the results of the examination of a fairly big collection of mollusca from the island of Mandul, north of Tarakan, East-Borneo. The material was collected by Dr. Van Holst Pellekaan while investigating the geology of Mandul in the service of the “Bataafsche Petroleum Maatschappij” (Royal Dutch/Shell). It was sent to Prof. K. Martin of Leyden for closer examination, and afterwards was embodied into the collections of the Leyden Geological Museum. Prof. Martin recorded the results of his preliminary examination, which excluded the bivalves, in a report to the “Bataafsche”, dated 12th January 1917. He came to the conclusion that the fossils were of a Pliocene age.

Description: La région que j’ai étudiée et relevée est située dans les Alpes françaises, à environ 4° longitude est et 50°15’ latitude nord, et à environ 2000 mètres d’altitude. Elle fait partie de la chaîne dite „chaîne de Belledonne” qui s’étend des massifs de Beaufort et du Grand Mont dans le N N E jusqu’à ceux du Taillefer et de la Mure dans le S S W. Cette chaîne forme du point de vue géographique comme du point de vue géologique le prolongement méridional de la chaîne des Aiguilles Rouges et de la chaîne du Mont Blanc. Celles-ci font partie de la zone externe des massifs cristallins des Alpes, dont le prolongement en Suisse est connu sous le nom de „massifs centraux des Alpes”. On entend par là les chaînes anté-alpines, et principalement hercyniennes des Alpes, constituées de roches du Houiller d’une part, de formations antérieures d’autre part, et recouvertes enfin de séries d’âges mésozoïque et permien. Dans le sud, cette chaîne hercynienne se divise de nouveau en deux branches, dont la plus orientale, celle des Grandes Rousses, aboutit à la partie déversée vers l’est, dans le massif du Pelvoux. Taillefer et la Mure forment le pivot le plus avancé de cet arc, et en effet ce dernier massif disparaît partiellement vers le S W sous le manteau sédimentaire du Dévoluy (cf. fig. 1). Le massif de Belledonne proprement dit, avec son point culminant: le Grand Pic de Belledonne, qui atteint à quelques mètres près les 3000, forme le tronçon central de cette chaîne et se trouve à quelques kilomètres à l’est de Grenoble dans le département de l’Isère. Il est limité à l’ouest par l’Isère et le Drac; au sud par la Romanche; à l’est par l’Eau d’Olle et au nord par la vallée de Laval et le Col de la Coche. Les Lacs Robert sont à peu près situés au centre du Massif de Belledonne, dans un cirque encoché dans le ralliement méridional de la chaîne occidentale à la chaîne principale du massif. Cette chaîne principale, comprise entre le Jasse Bralart au N et le Petit Vent au S, limite la région levée à l’est, tandis que la Botte et le lac Achard la limitent au sud. A l’ouest elle s’arrête au pied de la Croix de Chamrousse, le pivot méridional, et du Grand Eulier, le contrefort septentrional de la chaîne secondaire; et au nord audessus de la Prairie de l’Oursière. Cette région a une largeur de 3 km et une longueur de 4 km environ. Le Grand Sorbier dans la chaîne principale, avec ses 2522 m. en est le point culminant. L’impraticabilité du terrain fixa des frontières plus ou moins naturelles au lever. En particulier le flanc E de la chaîne principale, qui domine la vallée de Baton, à part quelques sentiers, n’est pas accessible sans danger, à cause du mauvais état de la roche schisteuse. Il en est de même pour la pente occidentale du Grand Eulier et du Casserousse, tandis que le flanc méridional du Petit Vent et de la Botte est un des versants de la gorge profonde de 2000 m. où coule la Romanche. C’est à cela qu’est dû le nombre restreint d’observations faites sur quelques parties de la périphérie.

Description: This paper deals with the investigation of soil samples taken near Terhorne on the North-East shore of the “Sneeker Meer”, an expanse of water in the province of Friesland. (see fig. I) According to the geological map, the peat around this large body of water is covered by an 1—4 dm thick layer of young marine clay, but at the place where our samples were taken, the peat reaches the surface. A series of samples were collected from the whole depth of this peat-deposit (see diagram I). The surface lies here 0.35 m below the level of the sea. (As the sealevel is taken the N.A.P., the average height of the water level at Amsterdam.) At a depth of 2.15 or 2.20 m the borer reached the underlying sand. It proved impossible to penetrate with the borer used by us more than 5 to 10 cm into the sand. This sand (diagram 1a, which shows the lowest part of diagram I on an enlarged scale) proved to be of a red-brown colour.

Description: The borings, on which this study is based, were made within a radius of circa 5 miles around Opeinde, a village in the province of Friesland near the Friesland-Groningen border.

Description: The following is an abstract of my notes made during the sessions of the Section for Nomenclature at the 7th International Botanical Congress at Stockholm. The Congress lasted, officially, from 12 till 20 July, 1950. The Section for Nomenclature, however, began to meet on July 7. I wish to state that this review has no authority or official capacity. I made notes for private use and because it seemed useful, on further consideration, to inform the Staff and collaborators of the Flora Nalesiana.. of the changes in the Rules adopted by the last Congress, it was thought best to publish a review here, pending the official publication of the new Rules as a whole. I am told that an official note or communication dealing with the results obtained by the Section for Nomenclature is being prepared and will appear in the first Nuntius Phytotaxonomicus, the new periodical to be issued by the International Bureau of Plant Taxonomy, Secretary Prof. Dr J. Lanjouw at Utrecht.

Description: We announce with great regret the death of Dr F. W. Foxworthy, forest botanist, who worked in the Philippines (1911-’ 18) and in the Malay Peninsula (1918-’32). His final work ‘Forests and Forestry of Tropical Asia’ is in the press, a volume in the New Series of Plant Science Books, publishes by Chronica Botanica Cy. C. C. Schröter, Curator of the Tjibodas Mountain Garden, was murdered September 15; a biography will appear in ‘Annales Bogorienses’.

Description: For this study which was suggested to me and promoted by Dr R. A. Maas Geesteranus I had at my disposal the material of the “Rijksherbarium” at Leiden, the herbaria of the Universities at Amsterdam, Groningen and Utrecht, and those of the “Koninklijke Nederlandse Botanische Vereniging” and the “Natuurhistorisch Museum”, Maastricht. I wish to express my thanks to the directors of these institutions for putting the material at my disposal, and above all to the staff of the “Rijksherbarium”, who gave me a great deal of valuable help, especially Dr Josephine Th. Koster, Dr Maas Geesteranus and Dr S. J. van Ooststroom. I am indebted to Dr H. C. D. de Wit for the solution of some intricate nomenclatural questions, to H. J. T. Tammel for drawing the figures. Thanks to the presence of the herbarium of Persoon in the “Rjjksherbarium” at Leiden, I was able to arrive at a better interpretation of a number of species described by him. This was especially important for the reason, that Persoon’s “Synopsis Fungorum” of 1801 is the “startingpoint” of nomenclature in the Gasteromycetes.

Description: The first result of this survey of the wide genera which have endemic species in New Caledonia is certainly to confirm the impression that there is indeed a noteworthy geographical association between Madagascar and that island, even if it is only a particular aspect of a more general relationship between Madagascar and Australasia as a whole. But the survey gives prominence also to another point, namely the unexpectedly small part that tropical Africa plays in the distribution of the genera reviewed. It almost seems as if there is some factor of exclusion affecting that great region, and there is no indication of any corresponding degree of relation between tropical Africa and New Caledonia such as has been detected between the latter and Madagascar.

Description: In the “Mikrographie des Holzes der auf Java vorkommenden Baumarten” I described 991 kinds of wood. Several of these belong to large genera, the majority to small. I found remarkably wide variations in the wood-anatomy of several specimens belonging to a single species of a large genus. These intraspecific differences in large genera are generally larger than interspecific differences in small genera. When identifying species by means of wood-anatomical characters, the wide intraspecific variability in large genera obstructs identification whereas in small genera identification is usually relatively easily executed. As a result, it is much easier to compose a key to the species in a small genus than in a large one. In my key to the Javan woods (Anatomische Bestimmungstabelle für die javanischen Hölzer, 1940, 83) it is repeatedly demonstrated; also in Mikrographie passim that taxonomic relationships are often blurred by this peculiar circumstance.

Description: In the course of my study on the wood-anatomy of Javan woods (Mikrographie des Holzes der auf Java vorkommenden Baumarten), I examined also many woods from mangrove-trees.\nMangrove has been the subject of much investigation; the community is usually described as xeromorphic. Mangrove woods proved to be different from woods belonging to species growing in other stations even if those species belonged to the same family or even genus. The data may be traced in my \xe2\x80\x9cMikrographie\xe2\x80\x9d but it seems more convenient to review them here.

Description: Little attention has been paid till now to the algae, transported to the Netherlands coast on drifting objects. About a century ago T. D. Vrijdag Zijnen and G. Bisschop (near Scheveningen, \xc2\xb1 1845), and L. H. Buse (between Wijk aan Zee and Zandvoort, \xc2\xb1 1840\xe2\x80\x941847) were the first to pay attention to this subject. The material collected, especially that by the first two investigators, is mentioned in the Prodromus Fl. Bat. (1853). The book of Van Goor (1923) contains a chapter on these algae, in which, however, only few new observations occur. The author is much indebted to Dr Josephine Th. Koster for her kind help, as well as to Dr S. J. v. Ooststroom. The material, collected by Vrijdag Zijnen, Bisschop and Buse is almost completely present in the collections of the \xe2\x80\x98Rijksherbarium\xe2\x80\x99 and the \xe2\x80\x98Koninklijke Ncderlandse Botanische Vereniging\xe2\x80\x99, Leiden. The material, collected during the last few years has for the greater part been brought together by the present author, and furthermore especially by K. Swennen (Den Helder), J. Stock (Amsterdam), A. Mulder (Haarlem) and P. Leenhouts (Scheveningen). This material belongs to the collection of the Rijksherbarium, Leiden, but most of it is, for the time being, put under the charge of the \xe2\x80\x9cComit\xc3\xa9 ter Bestudering van de Nederlandse Mariene Flora en Fauna\xe2\x80\x9d (\xe2\x80\x9cCommittee on the Netherlands\xe2\x80\x99 Marine Flora and Fauna\xe2\x80\x9d) and temporarily preserved in \xe2\x80\x9cHet Filiaal\xe2\x80\x9d, Leiden.

Description: Though the new names published in Thunberg\xe2\x80\x99s \xe2\x80\x9cFlorida\xe2\x80\x9d have been entered in the Index Kewensis, few botanists have tried to verify the status and synonymy of the new species proposed in this 2-thesis booklet. Thunberg\xe2\x80\x99s names were entered in Juel\xe2\x80\x99s \xe2\x80\x9cPlantae Thunbergianae\xe2\x80\x9d (1918, 412 pp.).\nThe diagnoses are generally too short and vague to allow a definite opinion. Only Schott, Mueller Arg., and F. E. Wimmer have examined material of resp. the Araceae, Euphorbiaceae, Campanulaceae.

Description: 1. This paper deals with a pollenanalytical investigation of holocenic peat-layers in Central Friesland. 2. One diagram shows a praeboreal spectrum with Betula in the dominant position, the first appearance of thermophilous trees (Corylus, Alnus) and a high percentage of Gramineous and Cyperaceous pollen. 3. Originally in all diagrams the percentages of Ericaceous pollen are low. 4. During the boreal time the peat formation was of little importance. A maximum of Corylus pollen in the boreal period has not been found here. 5. In the Atlanticum a thick layer of peat has been formed; the percentage of Alnus pollen remains high, the Quercetum-mixtum fluctuates between 10 and 25 per cent and there is also much Corylus pollen. 6. Two narrow clay-bands are present in the peat. They contain many pollen grains of halophytic plants, which indicates that there must have been two marine transgressions in the Atlanticum. These transgressions will have reached their farthest point in this region. 7. In the upper atlantic and subboreal peat-layers there are many fragments of Ericaceae and also a high percentage of Ericaceous pollen. 8. The Young Sphagnum peat consists of Sphagnum species of the Cymbifolia section. The presence of Fagus pollen never reaches a level of 10 per cent. 9. During the subatlantic transgression the Young Sphagnum peat has locally been washed away and was replaced by clay with many Phragmites rests. The author wishes to express his thanks to \xe2\x80\x9cIt Fryske Gea\xe2\x80\x9d, the Frisian association for the protection of nature, president Mr. M. WIEGERSMA, Drachten, for the permission to take samples at \xe2\x80\x9cHet Princehof\xe2\x80\x9d and for the assistance to this work. He is also highly indebted to Dr. F. P. JONKER for his assistance and interest during the investigation and to Prof. Dr. C. E. B. BREMEKAMP for correcting the English text.

Description: 1) In the \xe2\x80\x9cRijksmuseum van Geologie en Mineralogie\xe2\x80\x9d, Leyden, there is a small collection of Lower Tertiary mollusca from S.W. Celebes which allows of comparison with Abendanon\'s Celebes fossils described by Dollfus and kept in the \xe2\x80\x9cInstituut voor Mijnbouwkunde\xe2\x80\x9d, Delft.\nThe present note deals especially with Turritella krooni Dollfus (S.W. Central Celebes; said to be of Cretaceous age), a new subspecies T. krooni batuku\xc3\xabnsis (S.W. Celebes; Eocene), and the new T. krooni kalosiensis, formerly described as T. cf. angulata Sowerby and T. cf. assimilis Sowerby (S.W. Central Celebes; probably of Upper Eocene age, formerly considered to be of Oligocene age).

Description: The genus Celebochoerus was based by me (Hooijer, 1948) on two fragments of upper canines of rather large size, different from their homologues in Sus celebensis M\xc3\xbcller and Babyrousa babyrussa (L.), the two living species of Suidae of Celebes. The specimens originate from Pleistocene deposits at Desa Beru, Tjabenge (Sopeng district), about 100 km N.E. of Macassar, S. Celebes, and were collected by Mr. H. R. van Heekeren, prehistorian to the Archaeological Survey at Macassar.\nIn the meantime I have received more specimens of upper canines, collected by Mr. Van Heekeren at Desa Beru and also at Sompoh, 12 km N. of Beru. These specimens, like those first described, are surface finds and consequently more or less water-worn. They show a great deal of variation in size as well as in the shape of their cross-section. As time fails now to give a description of all the fragments, I shall describe the best specimens first.\nThe largest specimen is the greater part of a right upper C, 11 cm in length. It originates from Sompoh. At the proximal end (pl. I fig. 3, to the right) the apex of the pulp cavity is shown. The tooth is slightly curved upward and backward and tapers distally. The cross-section is similar to that in the first described specimens (Hooijer, 1948, fig. 1 a, b): the anterior surface is at right angles to the upper and both surfaces possess a shallow longitudinal groove. The posterior upper and lower angles are gradually rounded off, and there is a sharp groove in the lower half posteriorly. The greatest diameters are ca. 42 mm horizontally and ca. 39 mm vertically.\nThe present canine is covered on all sides by a thick whitish layer also

Description: GENERAL CHARACTER\nNatrix vittata, the striped swimmer, is a harmless little snake, about half a meter long and as thin as a little finger, living in Java on coastal plains and in the hills up to 1200 m above see level. In a given area she will be very common but in adjacent regions, which to us may present exactly the same character of humidity, altitude, temperature, vegetation, etc., there will be only very occasionally a Natrix vittata among the catch (de Haas, 1941a).\nEven in the field she is easily recognisable, as she will lift her head high enough to show the curious design of her ventral shields. If there is an opportunity for examining the snake more closely, the twin small white spots on the head shields will identify her. The colour of the body is light bronze with a dark stripe on the spine and two stripes running on the sides.\nAlthough she moves gracefully and swims very well, she is easily caught but even then never tries to bite. There is some wriggling of the body in the hand and around the wrist but the head is erect and projected as far forward as possible swinging right and left in the attempt of seeking a way to escape. There is really only one disagreable feature about this natrix: when caught and especially when afraid or when too roughly gripped, she will open the cloaca and discharge the contents with a characteristic, most persistent and very unenjoyable odour. She is easy to maintain in captivity and unlike many other snakes, will take food readily. Once I saw three of these natrices in a cage, each gripping a part of the same small frog. Her inquisitiveness in the search for food makes her run big risks and her agility is only partly compensation for the lack of strong powers. This is well

Description: There has been considerable confusion over the name Verbesina pseudoacmella and V. acmella published by Linnaeus in the Species Plantarum (1753, p. 901). He applied these names to definitions taken from his earlier work, Flora Zeylanica (1748, p. 144, 145, nos. 308 and 309), with only one unimportant alteration. The title page of the Flora Zeylanica shows that the book is intended as an account of Hermann\xe2\x80\x99s plants, and this is confirmed for the two species concerned by the close agreement between the descriptions published and the specimens in Hermann\xe2\x80\x99s Herbarium preserved in the Department of Botany of the British Museum. These two Linnean species must, therefore, be interpreted by reference to Hermann\xe2\x80\x99s specimens, regardless of the fact that figures cited by Linnaeus in the synonymy of each species (viz. Seba, Thesaur. 1, t. 10, 11; Plukenet, Alm. t. 159, f. 4) are of the plant which generally has been known as Spilanthes acmella.\nIn 1888, Trimen published notes on Hermann\xe2\x80\x99s Herbarium (Journ. Linn. Soc. Lond. (Bot.) vol. 24, p. 129); he identified the specimens representing these two species as follows: No. 308, Verbesina pseudo-acmella, as possibly a young specimen of Wedelia biflora DC.; and No. 309, Verbesina acmella, as Blainvillea latifolia DC. A drawing included in the herbarium he identified as \xe2\x80\x9cSpilanthes acmella\xe2\x80\x9d. As this drawing was not mentioned by Linnaeus, it must not be considered when interpreting the species. In his revision of the genus Spilanthes, A. H. Moore (Proc. Amer. Acad. Arts & Sci. 42, 1907, p. 521) rejected the name Verbesina pseudoacmella L. as referring to a mixture of genera, but retained \xe2\x80\x9cVerbesina acmella L.\xe2\x80\x9d as the basis of a species of Spilanthes.

Description: For this study which was suggested to me and promoted by Dr R. A. Maas Geesteranus I had at my disposal the material of the \xe2\x80\x9cRijksherbarium\xe2\x80\x9d at Leiden, the herbaria of the Universities at Amsterdam, Groningen and Utrecht, and those of the \xe2\x80\x9cKoninklijke Nederlandse Botanische Vereniging\xe2\x80\x9d and the \xe2\x80\x9cNatuurhistorisch Museum\xe2\x80\x9d, Maastricht. I wish to express my thanks to the directors of these institutions for putting the material at my disposal, and above all to the staff of the \xe2\x80\x9cRijksherbarium\xe2\x80\x9d, who gave me a great deal of valuable help, especially Dr Josephine Th. Koster, Dr Maas Geesteranus and Dr S. J. van Ooststroom. I am indebted to Dr H. C. D. de Wit for the solution of some intricate nomenclatural questions, to H. J. T. Tammel for drawing the figures.\nThanks to the presence of the herbarium of Persoon in the \xe2\x80\x9cRjjksherbarium\xe2\x80\x9d at Leiden, I was able to arrive at a better interpretation of a number of species described by him. This was especially important for the reason, that Persoon\xe2\x80\x99s \xe2\x80\x9cSynopsis Fungorum\xe2\x80\x9d of 1801 is the \xe2\x80\x9cstartingpoint\xe2\x80\x9d of nomenclature in the Gasteromycetes.

Description: The present paper deals with a small collection of Neogene fossils which has been made by the geologist Dr. M. Schmidt in the Sangkoelirang area 1), East Borneo. The locality is defined in Gerth\xe2\x80\x99s (1923) and Krijnen\xe2\x80\x99s papers (1931, loc. no. 175, p. 535).\nIt must be stated here that this locality has been mentioned incorrectly in literature, viz., as \xe2\x80\x9cHill near Sekoerau\xe2\x80\x9d instead of \xe2\x80\x9cCoral limestone, Hill near Sekoerau\xe2\x80\x9d. Dr. Schmidt\xe2\x80\x99s collection, which was sold to the Leyden Geological Museum in 1920 \xe2\x80\x94 about twenty years after being made \xe2\x80\x94 contains two different faunas from Sekoerau: vide infra.

Description: In April 1949 Mr. J. A. W. Lucas, a student of Biology and a careful collector of marine animals, supplied the Rijksmuseum van Natuurlijke Historie at Leiden with some specimens of Limnoria lignorum (Rathke), found in logs of wood washed ashore near Katwijk. These Isopods proved to be infested by a small Harpacticoid Copepod and by a species of Ostracod.\nThese animals were occasionally observed on the oral appendages and the legs. The Copepods were attached to various parts of the carapace, usually the telson, and were very small (about 0.5 mm) and the identification met with considerable difficulties. They proved to be identical, at last, with Harrietella simulans (T. Scott, 1894), a species known from the Firth of Forth and the Firth of Clyde in Great Britain and from Dr\xc3\xb8bak in Norway.\nA description of the specimens and a discussion of the synonymy, distribution and bionomics are given below. The Ostracods have not yet been identified.\nHarrietella simulans (T. Scott, 1894) ? Laophonte simulans T. Scott, 1804, p. 248, p1. 7 figs. 24-32, p1. 8 fig: 1.\nHarrietella simulans, T.

Description: In a paper on some birds from Sumatra in the Leiden Museum Dr. Junge (1948, pp. 314-15) lists two males of Limosa lapponica baueri Naum. taken by Mr. Van Heurn on the beach at Tandjong Tiram in the Deli district on 14 November 1921. In a short discussion on this record he refers to the fact that Vorderman (1890, p. 416) gives this species as probably occurring in Sumatra, and subsequently Robinson & Kloss (1923, p. 326) and Chasen (1935, p. 37) list it without query or comment. Dr. Junge adds that he failed to find the reference on which the later authors decided that the bird was definitely known from Sumatra. It is probable that no such reference exists and that Dr. Junge\'s paper constitutes the first authentic published record of the occurrence there of the Eastern Bartailed Godwit. The point at issue is a general one which has puzzled other workers in this field, and it would seem to be of interest to outline the situation briefly.\nRobinson & Kloss published two lists of the birds of Sumatra, the first in 1918, containing 527 birds, and the second in 1923, giving 574 birds. In a note to their first list the authors (1918, p. 284) make the following comment on their treatment of the "Charadrii formes" (= Suborder Charadrii), "In this group Vorderman records with certainty only 14 species that are found on the mud-flats of the Strait of Malacca with one or two exceptions".\nIt is clear that by mud-flats of the Strait of Malacca they mean the flats on the eastern (Malay Peninsula) side of the strait. They disallow 3 of the birds given by Vorderman, but make their own total up to 30. At that time they had apparently no reliable Sumatran records for the great majority of the 19 species which they thus added to the Sumatran list. The same procedure was followed in compiling the second list, published in 1923,

Description: The genus Podolestes, as far as at present known, is confined to the Malaysian subregion of the Indo-Australian Archipelago. Descriptions and drawings of structural details of four species are to be found in two of the writer\'s previous papers on Malaysian dragonf lies, viz.: New and little known Odonata of the Oriental and Australian Regions.\nTreubia, 15, 1935: 177-183, fig. 1-3.\nDescriptions and records of South-East Asiatic Odonata (II). Ibid. 17, 1940: 347-350, fig. 4-5.\nThe species of Podolestes have been found in marshes and along muddy creeks flowing through wooded areas in low country. Owing to their retiring habits the insects are but seldom encountered and all species are rare in collections. Little or nothing is known of their life-histories, and the larva is still unknown.\nThe six known members of the genus, two of which are here described for the first time, may be distinguished by the following Key to the species. 1. Dorsum of thorax uniform metallic bronzy black. Labrum, mandibles and genae shiny black. Ante-alar triangles bronzy-black, unmarked. Nervure Ac situated much nearer Ax2 than Ax1; nervure Ab complete, meeting Ac at the wing-margin. Quadrilateral short, markedly widened distally, costal and distal sides approximately equal in length in fore wing. Three to four postquadrangular antenodal cells. Male anal appendages of slender build, blackish in colour; superior pair a trifle longer than the inferiors; apex of inf. app. expanded, truncated and slightly notched 2. \xe2\x80\x94. Dorsum of thorax with two pairs of light-coloured spots on mesepisternum, and sides with an oblique band extending from below the spiracle upwards as far as the dorsal

Description: The material of Brachyura on which this paper is based was collected during some years on the Mexican coasts and I am greatly indebted to Dr. F. Bonet of the Escuela Nacional de Ciencias Biologicas in Mexico, D. F., for the opportunity he offered me to study this interesting material and for his kindness in presenting the larger part of it to the Rijksmuseum van Natuurlijke Historie at Leiden. At Dr. Bonet\'s request the seven specimens of Platychirograpsus typicus Rathbun were compared with De Man\'s cotype of Platychirograpsus spectabilis from Gaboon and my best thanks are due to the director and staff of the Zoological Museum in Amsterdam for their kindness in placing this male at my disposal.\nOn examining the Majids of this collection I came across two specimens (a male and a female) which I was unable to place. At my request Dr. John S. Garth of the Allan Hancock Foundation in Los Angeles was kind enough to examine the male and he informed me that not only he agreed with me that it belongs to a new species but that according to his opinion it should even be placed in a new genus; he also informed me that in the collections of the Allan Hancock Foundation some more specimens belonging to this interesting species are present and he most kindly sent me on loan a female and two young specimens which formed a valuable addition to the material at my disposal. I want to express here my sincere thanks for his kind advice and help.\n\nDROMIIDAE\nDromidia larraburei Rathbun, 1910 Dromidia sarraburei by error Rathbun, 1910, Proc. U. S. Nat.

Description: After a prolonged scrutiny of numerous colonies of Millepora in the collections of various museums I found, besides a number of colonies with open ampullae, ten specimens possessing ampullae with their coverings of a trabecular network. The chief details of these ampullae were described in a previous paper (Boschma, 1949 a). Afterwards I had the good fortune to obtain material of different species of Millepora from six localities showing ampullae in an undamaged state. These ampullae are figured and described in the present paper.\nI am greatly indebted to Mr. Harold Gatty of Suva, who enabled me to visit coral reefs in the Fiji Islands during the time I stayed in this locality (March, 1949). I want to thank Dr. C. H. Edmondson, curator, Bernice P. Bishop Museum, Honolulu, for a specimen collected by him on Johnston Island. I am much obliged to Dr. R. W. Hiatt, University of Hawaii, for presenting to me specimens collected by him at Bikini Island and at Yap Island. To Dr. P. Wagenaar Hummelinck, Utrecht, I owe an interesting specimen collected by him at Bonaire. I further want to thank Professor H. Graham Cannon, University of Manchester, for a specimen from the collection of the late Prof. S. J. Hickson, obtained at Brandewijnsbaai by the late Prof. Max Weber. Finally my sincerest thanks are due to Mr. A.\nSalverda, Groningen, who with great skill performed the difficult task of photographing of each colony a part of the surface showing numerous ampullae.\nAs even in these excellent photographs in many cases the ampullae are not distinctly showing off against their surroundings, from each photograph a diagrammatic copy of the upper or lower third part was made. These are

Description: In a previous paper (Boschma, 1933 b) descriptions were given of 22 species of Rhizocephala in the collection of the United States National Museum. In the cited paper especially attention was given to the details of the external and the internal cuticle, the data concerning the structure of the male organs and the colleteric glands were briefly described but not figured. The measurements of the type specimens were noted but no description was given of the shape of the animals. In a later paper (Boschma, 1937) some more details were described of the male organs and the colleteric glands of the specimens belonging to the genus Sacculina, but these structures up till now remain imperfectly known in the specimens belonging to other genera of the group.\nTo obtain a better basis for comparison with other specimens it seemed desirable to describe the hitherto imperfectly known details of the specimens.\nSome of the new names in the cited paper appeared to be synonyms of other names, whilst some species proved to belong to another genus than the one in which they originally were placed. The species are arranged here in the same order as in the original paper.\nIn most of the drawings of sections the excrescences of the cuticle are omitted.\nSacculina lata Boschma (figs, 1a, 4a).\nSacculina lata Boschma, 1933 b, p. 219, fig. 1 (external and internal cuticle) ; Idem, 1937, p. 273, fig. 55 (male organs), fig. 56 (colleteric gland).\nType specimen on Charybdis miles de Haan, Misaki, Japan, A.

Description: During the long years I was engaged in writing my \xe2\x80\x9cMikrographie\xe2\x80\x9d (1), my main purpose was to give a survey of the wood-anatomy of as many representatives of the javanesc wood flora as I could lay hands on, in connection with Koorders\xe2\x80\x99 and Valeton\xe2\x80\x99s \xe2\x80\x9cBijdragen\xe2\x80\x9d (2). My attention being almost exclusively absorbed by the descriptive side of my task, little attention was paid to eventual conclusions regarding family relationships, though some were incidentally pointed out.\nWhen this work of long years was completed, the need of a key for the identification of wood samples was felt. This I composed and completed just before the war. It was published in 1940 and written in German (3), as was the main work on which it was based. Immediately an English translation was prepared but though this was ready for the press as early as 1942, I was prevented from publishing it, at first because of the German occupation and later on for want of funds.

Description: Though Schlegel (1866, p. 200) as well as Hartert (1898, p. 135) pointed out that Carpophaga paulina, described by Bonaparte (1850, p. 35) and now known as Ducula aenea paulina (Bp.), originating from the Sula Archipelago (East of the East Coast of Celebes) seemed not quite similar to birds from Celebes, lack of sufficient material refrained these authors from separating Sula birds. But this was done by Siebers (1929, p. 152/3) who separated them under the name Ducula aenea sulana, on account of their smaller wing measurements and the darker (more chestnut coloured) nuchal patch. The Sula birds should be also smaller than nuchalis from the Philippines and (doubtful) pulchella from Togian 2) which, according to Siebers, should belong to the same "Formenkreis" as paulina and sulana.\nSiebers compared 8 birds from Sula (1 \xe2\x99\x82, 5 \xe2\x99\x80 and 2 sex. inc.) in which the length of the wing varied from 208 to 216 mm with 5 specimens (3 \xe2\x99\x82 and 2 \xe2\x99\x80) originating from Celebes (Paloppo and Bone) having wings varying from 218 + x to 234 mm and with 7 skins (4 \xe2\x99\x82 and 3 \xe2\x99\x80) from Muna and Buton with wing measurements diverging from 232 to 248 mm.\nBesides the 20 birds studied by Siebers I could examine 18 more skins of these pigeons, viz., 3 from the Sula Islands, 2 from Pulau Peleng (island off Northeast Coast Celebes), 4 from Bumbulan (North Celebes), I from North Celebes (exact locality unknown), 1 from Kulawi (Central Celebes), 2 from Bone (South Celebes; Siebers\' statement that Bone is situated in North Celebes must be a slip of the pen), 2 from South Celebes (exact locality unknown), 1 from Mara (Mare?, South Celebes) and 2 from Muna (island off the Southeast Coast Celebes). When comparing these 38 skins (31 specimens from the Buitenzorg Museum and 7 from

Description: Prof. H. Boschma, director of the Rijksmuseum van Natuurlijke Historie, sent me some Balanids associated with Millepora platyphylla Hemprich & Ehrenberg, partly preserved in formalin, partly in a dry state. The material was collected by the Snellius Expedition in 1930, the data concerning the present material are (Boschma, 1936, p. 19): "April 23-27. Obi latoe, northwest of Obi major (22). Most of the collecting was done on the reef of the small island Poeloe Toesa at the east side of Obi latoe. This is a highly varied reef with a great number of species of corals. A peculiar phenomenon observed here was the occurrence of multitudes of small brown flatworms on colonies of Merulina and Montipora, which covered the greater part of the surface of these corals. Among other groups of animals Balanids of large size attached to Millepora may be mentioned and several species of Foraminifera living on a sandy stretch with algae." In a letter dated August 24, 1949, Prof. Boschma wrote me in regard to the specimens dealt with here: "Part of the material is labelled "Poeloe Toesa", another part "Obi latoe". All this material was collected on the small island Pulu Tusa near the larger island Obi latu. The name of the Millepora is Millepora platyphylla Hemprich & Ehrenberg." The amended spelling of the localities is in conformity with modern practice.\nI want to thank Prof. Boschma for publishing the results of my investigations on these Balanids in the journal of the Leiden Museum.\nIn the material I found two species of Balanids, viz.: i, Balanus tintinnabulum occator Darwin; 2, Pyrgoma milleporae Darwin, forma typica Darwin and forma snelliusi n. f.

Description: This paper presents the results of the examination of a fairly big collection of mollusca from the island of Mandul, north of Tarakan, East-Borneo. The material was collected by Dr. Van Holst Pellekaan while investigating the geology of Mandul in the service of the \xe2\x80\x9cBataafsche Petroleum Maatschappij\xe2\x80\x9d (Royal Dutch/Shell). It was sent to Prof. K. Martin of Leyden for closer examination, and afterwards was embodied into the collections of the Leyden Geological Museum.\nProf. Martin recorded the results of his preliminary examination, which excluded the bivalves, in a report to the \xe2\x80\x9cBataafsche\xe2\x80\x9d, dated 12th January 1917. He came to the conclusion that the fossils were of a Pliocene age.

Description: Part IV of this monograph was published in volume 12 of this Journal, pp. 89\xe2\x80\x94120, 1942.\nSince 1941 the author can devote only a small part of his time to these investigations. This fact, and the shortness of paper available for scientific publications, made him decide to alter the way of publication: the extensive lists of references to literature and the records of distribution with every species have now been omitted. As further parts of this publication will follow with rather large intervals of time, from the present part onward complete lists of references will be added to each part, instead of supplements to the bilbliography published in part I.

Description: In the collections of the Leyden Geological Museum is a set of fossiliferous clay-stones which was long ago collected by the mining engineer Hulshoff-Pol in the coal quarries of Batoe Panggal 1), Eastern Borneo. He presented the collection in 1902 to Dr M. Schmidt, who at that time was making geological investigations in Borneo. After Dr Schmidt\xe2\x80\x99s appointment to a professorship in Stuttgart, the fossil collections made by him in Borneo were acquired by the Leyden Geological Museum (1920).\nFig. 1 roughly indicates the locality of Batoe Panggal, while Fig. 2 depicts the delta area of the Mahakkam or Koetei river and its neighbouring areas. The dotted area is again represented in Fig. 3 below.

Description: During the 1948-1949 Scientific Surinam Expedition, thorough zoological, botanical and geological explorations have been made in the coastal area and in the anterior mountain region of Dutch Guiana.\nThe number of macrurous Decapods collected is large, though the number of species represented is relatively small. These shrimps have been collected at the following localities: 1. Coronieweg. This is the highway from Coronie to Paramaribo. Coronie is situated in the N.W. part of Surinam, about at 5\xc2\xb0 53\' N 56\xc2\xb0 20\' W.\nThe Coronieweg localities are accompanied by a piket- and a km-number, e.g., Coronieweg, piket 216, km N 0.2. The piket-number indicates the distance in hundreds of meters which a certain point on the highway (the piket) is situated east of Coronie. The km-number indicates the number of kilometers that the actual locality is situated due north or south of the piket. The indication Coronieweg, piket 216, km N 0.2, thus means that the locality is situated 0.2 km north of a point on the highway, which point lies 21.6 km E. of Coronie. 2. Republiek. This is a locality on the railway, which runs from Paramaribo southwards into the interior of Surinam. Republiek is situated about 43 km S. of Paramaribo, on the Coropina creek, which empties in the Para, a branch of the Surinam River. 3. Paramaribo. 4. Plantation "Peperpot", a plantation on the east bank of the Surinam River, somewhat above Paramaribo. 5. Moengotapoe. A locality in the N.E. part of Surinam at about 5\xc2\xb0 34\' N 54\xc2\xb0 14\' W. The expedition went from Moengotapoe in a straight line due
