Description: The editor has received the first and second fascicle of a treatise of the vascular plants of West Virginia. According to the preface this flora, when complete, will present descriptions, illustrations, geographical data and other information, particularly of local interest for the approximately 2000 species found growing without cultivation in that State. The first part contains the Pteridophyta, Gymnospermae, and Monocotyledoneae, the second part the Dicotyledoneae, p.p. (Saururaceae-Leguminosae). Keys are given for genera and species. The rather short descriptions are completed by many for the greater part original line drawings. Nomenclature and sequence are those of the 8th edition of Gray’s Manual, 1950, by M. L. Fernald.

Description: On a private collecting trip to the Netherlands Antilles, in the winter of 1948—1949, I had the opportunity of studying an infestation of the sapodilla, caused by a well-known kind of fruitfly, Anastrepha serpentina, which, however, has never before been reported from these islands. The identification was kindly confirmed by E. McC. Callan, Imperial College of Tropical Agriculture, Trinidad; specimens were compared by him with material named by A. Stone, deposited with the collections of the I.C.T.A. My grateful thanks are due to the Department of Agriculture of the Netherlands Antilles for giving a financial support which made entomological work possible, and especially to Agricultural Superintendent B. A. Bitter, for putting at my disposal the facilities of the Agricultural and Experimental Gardens at Cas Corá.

Description: Comme la carte de la page 8 le montre le Massif du Saint-Barthélemy se trouve dans le Dépt. de l'Ariège à l'Est et au Nord de la rivière dont le département porte le nom et entre Foix et Ax-les-Thermes. Le terrain examiné est formé entièrement de roches paléozoïques ou plus anciennes, bordées au Nord, au Sud et à l'Est par des formations mésozoïques. Ce terrain est limité également de Paléozoïque au côté Ouest, le long d'une faille qui sépare le Massif du Saint-Barthélemy du Massif de l'Arize. De cette manière le Massif du Saint-Barthélemy est un des Massifs primaires Nord-pyrénéens: c'est-à-dire l'une des îles de roches paléozoïques dans le Mésozoïque, situées au Nord de la zone axiale, qui est entièrement constituée de roches paléozoïques. Les principaux Massifs Nord-pyrénéens sont de l'Est à l'Ouest: le Massif de l'Agly, du Saint-Barthélémy, de l'Arize, des Trois Seigneurs, de Castillon et de la Barousse. Il existe en outre encore quelques petits Massifs.

Description: In der Nachbarschaft von Flüssen und größeren Bächen nimmt der Löß sehr häufig eine sandige Beschaffenheit an, in vielen Gebieten ist sogar die Sandkomponente in Form von verschieden starken Schichten (Sandbänder) eingeschaltet. Die vorliegende Arbeit beschäftigt sich in der Hauptsache mit der Lagerung der Sandbänder im vertikalen Profil und mit den Veränderungen in horizontaler Richtung. Auf Grund der allgemeinen Ausbildung und der Körnungsunterschiede des Lößes konnten westlich Königgrätz 4 Faziesbereiche unterschieden werden und zwar die Flugsand-, Bänder-, Übergangs- und Normalfazies. Die 4 Fazieszonen folgen von O nach W aufeinander. Die speziellen Untersuchungen an den Sandbändern führten zu folgenden Ergebnissen: 1. Die Abnahme des prozentualen Anteils der Gesamtmächtigkeit der Sandbänder am Löß erfolgt linear mit dem Logarithmus der Entfernung vom Auswehungsgebiet. 2. Die durchschnittliche Anzahl der Sandbänder je Meter Löß ändert sich mit der Zunahme der Entfernung vom Ursprungsgebiet, wie im einzelnen aus Abb. 10 hervorgeht. 3. Neben der Gesamtmächtigkeit und der Anzahl der Sandbänder wurde auch die Häufigkeit der verschiedenen Mächtigkeitsstufen ermittelt und graphisch aufgetragen (Abb. 11). Dabei ergab sich, daß in unmittelbarer Nähe des Auswehungsgebietes neben wenigen 9 und 10 cm mächtigen Bändern die 2 und 2,5 cm starken überwiegen. In einer Entfernung von etwa 300 m vom Flußufer dominieren die 1 und 1,5 cm starken. Weiter nach W nehmen aber nach und nach die dickeren Lagen wieder zu, so daß am Ende der Sandbänderfazies die 2 und 2,5 cm starken die häufigsten sind. Aus den mitgeteilten Ergebnissen und aus zahlreichen Körnungsanalysen wird geschlossen, daß sowohl die eingelagerten Sandschichten als auch der gößte Teil des Lößes äolischen Ursprungs sind. Sandlagen und Löß wurden durch östliche Winde aus dem breiten Tal der Elbe ausgeweht und auf die benachbarten Höhen transportiert. Dabei gelangte der in Form von Bändern abgelagerte Sand bis zu einer Entfernung von ca. 700 m. Die Kornfeinheit des Lößes nimmt nach W hin immer mehr zu. Weitere Beobachtungen an dem Bystrice- und Cidlina-Tal im W des Untersuchungsgebietes bestätigen die Annahme von der Auswehung des Lößes und der Sandschichten aus den Tälern durch Winde aus östlicher Richtung. Daß die allgemeine Lößverbreitung auch von der Breite der Täler abhängig ist, zeigt ein Blick auf die Karte (Abb. 1).

Description: Ever since it became apparent that terrestrial animals ranging over large continental areas generally showed a certain degree of gradual geographic variation, attention has been focused on the colour variation of the Jay, Garrulus glandarius, in Europe. Surely the Jays belong to those species of palearctic land birds in which the formation of geographical differences must be considered to be exceptionally favoured: HARTERT (1903\xe2\x80\x941922; including HARTERT & STEINBACHER 1932) recognized as many as 10 European races of the Jay by name, whereas Kleiner (1935\xe2\x80\x9438) in his monographic treatment of the species numbered as many as 9 races in the same region. In several instances of the geographic variation of the Jay the differences are exceedingly striking, e.g. between the reddish brown Jays from Ireland and the dark grey ones from northern and central Europe. Still, the intergradations are so gradual and the individual variation is so unexpectedly large, that the application of subspecific names as a method of expressing geographical variation has proved to meet with serious difficulties. The resulting confusion of names for years has stressed geographical differences being of only minor importance and has obscured others meriting a closer attention.\nHowever, it was not at all for nomenclatorial purposes that this study was started, nor in order to propose a new arrangement of the geographic races of the Jay in Europa. That, in spite of this, these topics have been dealt with in one of the following chapters of this paper must be explained from the fact that the author failed to see a possibility to avoid them. The main purpose of this study was to investigate instances of \xe2\x80\x9cclinal variation\xe2\x80\x9d, meaning the presence and the origin of geographical character gradients. \xe2\x80\x9cCharacter gradients in the frequencies or in the expression of variable characters\xe2\x80\x9d (DOBZHANSKY 1947, p. 67) occurring in continuous geographical areas have seriously attracted the attention of students of population genetics and of micro-evolution. Hence it seemed worth while to select a suitable subject for a comparison of local individual variation with geographical variation and to study the origin of the clines. This is what the author has tried to do in the course of the present study on Garrulus glandarius.

Description: In 1935 Lee Boone in Bulletin of the Vanderbilt Marine Museum vol. 6 (pp. 160-163, pls. 41, 42) described and figured a shrimp, which she thought to belong to a new genus and species of the Palaemonid subfamily Pontoniinae, and which she named Vanderbiltia rosamondae. Boone\'s figures and description show that the specimen cannot possibly be a Pontoniid shrimp, but it proves to be impossible from these data alone to place the species anywhere in the system. In my report on the Pontoniinae of the Siboga Expedition (Holthuis, 1952, p. 22), therefore, I listed Vanderbiltia rosamondae (misspelled rosamundae by me) under the "species described as Pontoniinae, but not belonging in this subfamily\'\', and remarked that the species shows some resemblance to the Atyidae and that it might be juvenile.\nThough according to the description and figure Vanderbiltia in some characters resembles the Atyidae, in others (e.g., the shape of the chelae) it differs so much from any of the members of that family that it hardly could be placed there. The identity of Vanderbiltia rosamondae Boone, which species had not been recorded since the original publication, therefore remained a mystery that only could be solved by examination of the type specimen itself.\nIn April 1953 I had the pleasure of visiting the Vanderbilt Museum in Centerport, Long Island, New York. Mr. Woodhull B. Young, curator of the Museum, whom I am profoundly thankful for giving so much of his valuable time to show my company and myself around in the Museum, and for extending many courtesies to us, was good enough to allow me to take the type specimen of Vanderbiltia rosamondae (or Vanderbiltia mirabilis, under which name it was exhibited in the Museum) with me to Washington,

Description: Among the fossil proboscidean remains collected by Mr. H. R. van Heekeren in the Tjabeng\xc3\xa8 area, Sopeng district, about 100 km Northeast of Macassar in Southwestern Celebes there are a number of very small teeth.\nThey can be referred to the species of Archidiskodon of which I originally described two specimens of M2 or M3, some molar fragments, the distal end of an ulna, and the proximal end of a tibia (Hooijer, 1949), to which could later be added a fine M3, and an M1 or M2, both completely preserved (Hooijer, 1953a).\nArchidiskodon celebensis Hooijer is the smallest species of Archidiskodon known at present. Its molars are only one-half as large in linear dimensions as those of Archidiskodon planifrons (Falconer et Cautley), and they agree with the latter in their ridge-plate formula, configuration of the enamel figures of the worn plates, long roots, and degree of hypsodonty.\nAs will be seen from what follows, the Celebes pygmy elephantine also agrees with A. planifrons in what is considered to be the most important distinguishing character of A. planifrons, viz., the presence of premolars.\nMilk molars have been less intensively studied than molars; there are three of them, in Archidiskodon as well as in the recent species Data on DM2-4 of Archidiskodon planifrons from the Upper Siwaliks of India, of A. meridionalis (Nesti) from the Villafranchian of Europe, and of A. exoptatus Dietrich from the Early Pleistocene of East Africa are given in Fal1) A preantepenultimate milk molar (DMI) occasionally develops in the African elephant (Morrison-Scott, 1939). coner and Cautley (1845-49), Falconer (1868), Adams (1877-81), Pohlig (1888-91), Weithofer (1890), Dietrich (1942), and Osborn (1942).

Description: Since 1948 Mr. H. R. van Heekeren, then prehistorian to the Archaeological Survey of the Dutch East Indies, kept up an intermittent search for fossil teeth and bones that occur in association with Palaeolithic artifacts at Beru and Sompoh, near Tjabenge (Sopeng district), about 100 km Northeast of Macassar in Southwestern Celebes. These sites are now known to yield an interesting vertebrate fauna, presumably Pleistocene in age, the first found elements of which were described a few years ago (Hooijer, 1948, 1949).\nOne of the most remarkable discoveries in the Tjabeng\xc3\xa8 area made by Mr.\nVan Heekeren is a small elephantine that I have named Archidiskodon celebensis (Hooijer, 1949). It was based on an almost complete and unworn upper molar, and on a similar but worn specimen, while parts of an ulna and a tibia were also described. I ventured to interpret these fossils as belonging to a dwarf archidiskodont elephant (standing about six feet high at the shoulder when adult), in a curious way retaining the characters of Archidiskodon planifrons (Falconer et Cautley) from which I took the Celebes elephantine to have been derived.\nIt is a great pleasure, again, to acknowledge my indebtedness to Prof. Dr.\nA. J. Bernet Kempers, Head of the Dinas Purbakala R.I. at Djakarta, Java, who entrusted the Celebes fossil vertebrates to me for study. Moreover, I wish to thank Dr. Edwin H. Colbert of the American Museum of Natural History, New York, for stimulating discussions and kind advice. The proboscidean remains to be described below are the best specimens that Mr.\nVan Heekeren ever collected in Celebes in the years 1948 to and including 1950, and credit should go to him especially for his perseverance in the field without which these valuable specimens would never have been collected.

Description: I. Attacus dohertyi dammermani nov. subspec. (Plate II) Large, apex of fore wing moderately produced, general coloration of wings, head, notum including patagia, and abdomen rather light reddish brown, several intersegmental folds between the abdominal tergites blackish.\nIn both wings the terminal area somewhat lighter, more yellowish brown, in apex of fore wing grading into yellowish. Hind wing with the apical area markedly reddish. In fore wing the dark apical spot and red dash weak, submarginal line practically wanting, in hind wing a somewhat undulating submarginal dark line well developed. Postmedian band in both wings strongly serrate, but not bent inwards. Antemedian band in both wings less distinct, not serrate, in fore wing angled on base of v2, in hind wing curved inwards. The vitreous patches in both wings very large, guttiform by having the base curved outwards, the basal angles rounded, and the top elongated and pointed towards the postmedian band. In both wings with two additional vitreous patches which are in fore wing slightly larger than in hind wing.\nIn hind wing the lower patch communicates with the interior black border of the postmedian band. All these spots bordered by a black margin. The interior orange yellow border, so obvious in many dohertyi specimens, is wanting or indicated by some inconspicuous traces only. Underside corresponding with upperside, the outer half very light, as in atlas, but the subterminal markings in both wings practically wanting or obsolete. Lateral markings of abdomen much less developed than in atlas.\nI \xe2\x99\x80, 25 cm, holotype, W. Sumba, IV. 1925, labelled Dammerman, Sumba Exp., in Museum Leiden. 2.

Description: During the Scientific Surinam Expedition 1948-1949 Mr. P. H. Creutzberg collected only a few specimens of birds, which came in the Leiden Museum. Most of the collected birds belong to species well known from Surinam as Butorides striatus, Piaya cayana, Rhynchocyclus flaviventris.\nOthers like Leucopternis albicollis are not exceptionally rare. One species, however, proved to be new for Surinam. It is of interest to mention it here together with some other species, rarely recorded from Surinam, collected by Mr. W. C. van Heurn in 1911 and by Mr. H. A. Boon in 1901.\nLeucopternis melanops Lath.\nA specimen (\xe2\x99\x80) of the Black-Faced Hawk was collected by Mr. W. C. van Heurn at Guyana Goudplacer on October 9, 1911. Guyana Goudplacer is situated on the railroad about 100 km from the coast, approximately at 5\xc2\xb0 15\' N and 55\xc2\xb0 27\' W. Kappler in his book "Holl\xc3\xa4ndisch-Guiana" (1881, p. 164) gives a list of the birds, which he collected for the Stuttgart Museum.\nIn this list he also mentions this species, but other records of specimens from Surinam seem to be lacking. The measurements are: wing 238, tail 156, culmen from cere 22, tarsus 63 mm.\nSpiza\xc3\xabtus ornatus (Daudin) A specimen of Mauduit\'s Hawk-Eagle was shot at the plantation Johanna Catharina on the Saramacca River by Mr. Bosch Reitz on September 22, 1911. It was included in the collection that Mr. van Heurn sent to the Leiden Museum in 1911. Mr. van Heurn reports that it is a rare species in Surinam. It was only recorded by Kappler in his above mentioned list.\nMeasurements: wing 372, tail 264, culmen from cere 33, tarsus 100, hind toe without claw 40 mm. Wing/tail index 70.9. The specimen was unsexed

Description: The Rhizocephala, parasites of Crustacea of various orders, form a small group of animals, of which the comparatively small number of published records become rather easily accessible in a complete manner, so that in this respect the group lends itself for a survey of the occurrence and the distribution of the species in the Pacific area. The available data are widely scattered in the literature (cf. references at the end of the present paper), most papers dealing with one or a few species, some publications containing data on animals of the group from a distinct geographical area, others again giving the results of an examination of the material of the group preserved in a certain museum. A survey of the available data proves that in certain regions of the Pacific our knowledge concerning the Rhizocephala is fairly well advanced, whilst on the other hand in other parts of the area hardly anything has become known in respect to the parasites of the group.\nA list of the species known to occur in the Pacific region follows here, arranged under the various genera. To save space the author\'s names Boschma (B.), Van Kampen & Boschma (K. B.), and Shiino (Sh.) have been abbreviated as indicated in brackets. Behind each name one or more numbers are added in brackets, these refer to the geographical areas briefly to be indicated as: I, Japan; 2, China; 3, Philippine Islands; 4, South East Asia; 5, East Indian Archipelago; 6, New Guinea and Torres Strait; 7, North East and East Australia; 8, North America, including Bering Sea; 9, South America; 10, Central Pacific. It is not intended to regard these regions as well defined faunal provinces; for the purposes of the present paper, however, they form regions of a more or less distinct character.\nPeltogaster boschmai Reinhard (8), depressus Reinhard (8), latus van

Description: INTRODUCTION\nIn the summer of 1950, the present writer spent a three weeks\' holiday dredging in the Great Bitter Lake. Plans to collect specimens in that area for the Rijksmuseum van Natuurlijke Historie at Leiden had, unfortunately, to be drawn up somewhat hurriedly, but at least the most essential equipment was complete by the beginning of the writer\'s stay at Fayed, on the western shore of the Lake. Between August 18th and September 5th, the Great Bitter Lake was explored as well as possible under the circumstances.\nThe investigation discussed below was, as is fully realised, of a limited character; it consisted almost exclusively of operations for collecting marine organisms, though on a fairly large scale. However, it was considered preferable to do the work with the means available rather than let this chance slip for want of ideal circumstances, the more so because no extensive exploration of the bottom fauna of the Bitter Lake had ever been carried out in the past. The discovery of a few distinct plant zones in the Lake will, it is hoped, add to the ecological interest of the collections made.\nTo Mr. J. Doorn, of the Anglo-Egyptian Oilfields Ltd., the writer owes many thanks for the able manufacture of a most serviceable marine dredge.\nThe Compagnie Universelle du Canal Maritime de Suez kindly made available a detailed hydrographic map of the Great Bitter Lake. The writer is also much indebted to Miss Dr. J. Th. Koster, Rijksherbarium, Leiden, for the identification of the collected plants.\n\nBRIEF COMMENTS ON THE ISTHMUS OF SUEZ\nThe excavation of the Suez Canal has added much interest to the manifold problem of the extent of intermingling between marine faunal provinces,

Description: A recent collecting trip extended the region to which these Studies originally referred in such a way that it seemed wise to change the original title, so that not only the arid area off the North coast of South America was indicated as the field of study.\nAlthough as yet these Studies are principally based on material collected by the editor on his three trips to the Caribbean, this volume proves that results obtained from material of different origin will be incorporated.

Description: Fifteen years ago, H. Helfer in his paper \xe2\x80\x9dEinige neue Pantopoden aus der Sammlung des Zoologischen Museums in Berlin\xe2\x80\x9d (Sitz. Ber. Ges. Naturf. Fr., Berlin 1937 (1938), pp. 162\xe2\x80\x94185) established 5 new genera, each based on a new species, 2 new species belonging to known genera, and 3 new varieties.\nSince then, several authors have expressed their doubt about the validity of Helfer\xe2\x80\x99s new forms. Indeed, Helfer\xe2\x80\x99s descriptions and figures leave doubt as to the affinities of the material. Often the descriptions and the figures are contradictory e.g., in Heteronymphon kempi var. dimorpha the figure of the chelifore shows one suture too much, and in Pycnosoma batangense a suture too little.

Description: A faunal list of the birds of the Moluccan Islands has been previously published by the first author (Treubia 19, part 2, May 1948, pp. 323\xe2\x80\x94 402). Additional data have been collected since by Mr. G. A. L. de Haan during a period of several years in which this zealous collector lived in Halmahera and visited the islands Morotai, Ternate and Gebe. It seemed us worth while to publish the species and new localities from the data collected by Mr de Haan, which are not contained in the previous list. We take this opportunity to add some data from literature, published after May 1948 or overlooked by the first author, some data from the collections of the American Museum of Natural History, New York, and the Rijksmuseum van Natuurlijke Historie. Leiden, and to add some corrections to the first list.\nWe want to express our sincere thanks to Mr de Haan for all troubles taken to provide us with material and information, to Dr E. Mayr (New York) for his corrections and valuable information, to Dr M. A. Lieftinck (Bogor) and Prof. Dr H. Boschma (Leiden) and Dr G. C. A. Junge (Leiden) for material put at our disposal.

Description: The family of the Zosteropidae encloses, besides the very large and uniform genus Zosterops, a number of aberrant forms, especially in the East Indian Archipelago, that, though doubtless closely related to Zosterops, are too distinct to be united with this genus without objection.\nSeveral authors have engaged themselves with the problem of the classification of these forms, without arriving at a definite conclusion (cf.\nHartert, 1897, Lophozosterops; Stresemann, 1940, p. 66, Pseudo zosterops).\nThe inclusion of many of these forms in the genus Zosterops, as propagated by Hartert, and by Chasen (1935), is no final solution either, and later workers, such as Delacour & Mayr (1946), Delacour (1946), and Voous (1948), investigators who are certainly not in favour of unnecessary splitting of genera, place several species in a separate genus, Apoia (A. goodfellowi, A. javanica, A. squamifrons).\nIn the present paper a preliminary effort is made to arrive at a natural classification of these forms.\nI am well aware that the recognition of several monotypic genera, as here proved necessary, is not attractive to ornithologists, but the alternative suggested by Stresemann (1940), and put into practice by others, to unite all these species with Zosterops, seems more objectionable, not only because of the disturbance in the homogeneity of the compact genus Zosterops, but also because of the fact that the relations that certainly do exist between several of the "aberrant" forms would be completely obscured by such an act.\nThe existence of these relations has not always been clearly recognised, as shown by the diverging generic names used for certain species.\nIt would lead to useless repetition to give complete descriptions of all the

Description: Some time ago I was asked to identify a fossil coleopteron which had been found in the drill cuttings of an oil well in the Southern part of Sumatra. As the fossil is only a few millimetres long it may be mentioned as an amazing fact that so small an object has been found during rather rough work like oil drilling.\nThe details of the locality as given by Mr. A. Wright Jr. of the N.V.\nStandard-Vacuum Petroleum Maatschappij are as follows: "The well is one of our Kaja wells, a wildcat well located 3.3 kilometres N. 300 E. from the northeast edge of the Djirah oilfield. The drill cutting was obtained from a depth of 1930 feet subsea. Although, in drill cuttings, there is a certain measure of uncertainty as to the exact level of derivation, we have sufficient evidence to be sure that the fossil actually derives from this depth.\nThe age is Tertiary-e; it occurs below beds of Baturadja stage age, but 200 feet above a lepidocyclina-bearing horizon. The fossil occurs in a shale interval of a formation which is generally non-fossiliferous; conditions were presumably marine, but either oligotrophe or toxic; the water at the time of deposition was shallow." The fossil is pyritized, dark bronze-greyish in colour. It is nearly free from substrate, though in some crevices a light grey, rather soft, somewhat fattish substance is found which can be taken away rather easily.\nThe fossil was sent to the Rijksmuseum van Natuurlijke Historie at Leiden, mounted in a small box on a slide, pasted to the bottom with tragacanth. During the studies it was left in the small box, and kept in an exsiccator to preserve the fossil against deterioration by atmospheric influence.

Description: INTRODUCTION\nThe genus Metabelba was created by Grandjean in 1936 for Belbidae of which the solenidions of tibiae II and III are coupled with protective hairs, but of which the solenidion of tibia IV is free, long, and tactile. The genus belongs to the group of rather small species that are never covered with foreign material, but of which the cerotegument is very thick, especially on the moniliform legs, whilst the adults often bear the larval and nymphal skins.\nThe species have three or four lateral apophyses : one (which is not always present) between leg I and leg II, two between II and III, and one between III and IV. We have been in doubt as to the nomenclature of these apophyses, for although they have generally been regarded as tectopedia, they do not protect the trochanteres. Grandjean (in litt.) recently proposed to us the following notation. The apophysis between I and II is restricted to some members of the Belbidae, and in the present paper it is simply called anterior apophysis (a.a.). The two apophyses between II and III occur in several families; they protect the sejugal stigma; here they are called anterior and posterior parastigmatic apophyses (a.p.a., a.p.p.). It is obvious that the fourth apophysis is a discidium (dis; cf. Grandjean, 1952, p. 31).\nThere are no spinae adnatae but there is often one pair of protuberances under the anterior border of the notogaster, opposite to a corresponding pair on the propodosoma ; sometimes there is even a second pair of protuberances on the propodosoma, also situated in the posterior part.\nThe type of the genus is Damaeus papillipes Nicolet, a species that was insufficiently described, but of which Grandjean discovered specimens at

Description: The Compositae of the Malay Archipelago and New Guinea collected by O. Beccari have been studied by U. Martelli in 1883. Afterwards J. Mattfeld reconsidered some of Beccari\xe2\x80\x99s Compositae, chiefly specimens of the genus Blumea, founding also a new species, Anaphalis arfakensis, on a Beccari specimen from Papua.\nThe re-examination of the above mentioned collection brought to light some misinterpretations.

Description: Dr P. Wagenaar Hummelinck entrusted me with the identification of the mosquitoes he collected during his trips to the West Indies in 1936\xe2\x80\x941937 and 1948\xe2\x80\x941949. Although dr Hummelinck told me that it was not his intention to catch representative material, the present collection is of particular hygienic and biological interest as some mosquitoes were found on islands from which they had not been reported before.\nThis paper deals with 16 species: Wyeomyia celaenocephala \xe2\x80\x94 Cura\xc3\xa7ao, Anopheles pseudopunctipennis pseudopunctipennis \xe2\x80\x94 Margarita, Cura\xc3\xa7ao, Aruba, Anopheles albimanus \xe2\x80\x94 St. Martin, A\xc3\xabdes taeniorhynchus \xe2\x80\x94 Cura\xc3\xa7ao, Saba, Dog Island, A\xc3\xabdes aegypti \xe2\x80\x94 Cura\xc3\xa7ao, Aruba, St. Barth\xc3\xa9lemy, St. Martin, Haemagogus anastasionis \xe2\x80\x94 Cura\xc3\xa7ao, Aruba, Psorophora confinnis \xe2\x80\x94 Bonaire, Cura\xc3\xa7ao, Psorophora pygmaea \xe2\x80\x94 St. Martin, Deinocerites cancer \xe2\x80\x94 St. Martin, Culex erraticus \xe2\x80\x94 Cura\xc3\xa7ao, Culex americanus \xe2\x80\x94 St. Eustatius, St. Martin, Culex bahamensis \xe2\x80\x94 St. Eustatius, St. Barth\xc3\xa9lemy, St. Martin, Culex maracayensis \xe2\x80\x94 Cura\xc3\xa7ao, Culex chrysonotum \xe2\x80\x94 Suriname at Zanderij, Culex coronator \xe2\x80\x94 Venezuela near La Guaira, Culex nigripalpus \xe2\x80\x94 Bahamas, on South Bimini, and Culex quinquefasciatus \xe2\x80\x94 Bonaire, Cura\xc3\xa7ao, Aruba, St. Eustatius, St. Martin.

Description: Depuis longtemps on trouve dans la litt\xc3\xa9rature sur la g\xc3\xa9ologie des Pyr\xc3\xa9n\xc3\xa9es des discussions sur les lherzolites et les ophites, concernant leur origine, leur \xc3\xa2ge et leur mode de formation. En g\xc3\xa9n\xc3\xa9ral ces discussions ont rendu difficile l\'\xc3\xa9claircissement de ce probl\xc3\xa8me et un r\xc3\xa9sum\xc3\xa9 de toute la litt\xc3\xa9rature manque jusqu\'ici. Dans un rapport in\xc3\xa9dit de l\'Institut g\xc3\xa9ologique de l\'Universit\xc3\xa9 de Leyde M. H. Heetveld a rassembl\xc3\xa9 toutes les donn\xc3\xa9es sur les lherzolites et ophites, et en v\xc3\xa9rit\xc3\xa9 il est difficile d\'en tirer une conclusion. C\'est pourquoi nous ferons dans cet article une proposition quant \xc3\xa0 leur d\xc3\xa9finition et leur \xc3\xa2ge et mode de formation.\nLes deux termes lherzolite et ophite sont bien d\xc3\xa9finis: la lherzolite est une roche consistant essentiellement en olivine ,parfois serpentinis\xc3\xa9e, et en plus de diallage ou diopside, bronzite et picotite. En r\xc3\xa9alit\xc3\xa9 une lherzolite est une p\xc3\xa9ridotite avec un caract\xc3\xa8re sp\xc3\xa9cial.

Description: Whereas scientific research on inhibiting substances has mainly occupied itself with the effect of these substances on the germination process, I was able to demonstrate the presence of a root-inhibiting agent during my studies on root formation in Fuchsia hybrida and Pelargonium zonale (Stolk, 1952). In connection with this previous investigation I tried to find out whether a similar substance is present as well in bulbous plants and, by doing so, as a suitable species for my experiments the Liliaceous Allium Cepa was selected. My principal object was to corroborate and, if possible, extend the results obtained with Fuchsia and Pelargonium. A confirmation appeared highly desirable because the experiments with Fuchsia and Pelargonium could not possibly be very accurate on account of the direct method of measuring and that is why I used in my experiments with Allium a root-auxanometer which will be described in the following section.\nSubstances retarding germination were demonstrated in the slime of Viscum album by WIESNER (1894), in the fruit pulp of ripe tomatoes by OPPENHEIMER (1922), in tomato juice by REINHARD (1933), in other pulpy fruits such as apples, pears, quinces and tomatoes by K\xc3\x96CKEMANN (1934), in the exocarp of buckwheat by LEHMANN (1937), in the fruits of Helianthus annuus and Avena sativa by RUGE (1939) and in Beta by FR\xc3\x96SCHEL (1939, 1940). That not one and the same inhibitor is involved, is evident from the fact that the above-mentioned authors found differences between the inhibiting substances they studied in their behaviour towards high temperatures. The inhibiting substances found by OPPENHEIMER and LEHMANN, for instance, are thermolabile. those discovered by REINHARD, K\xc3\x96CKEMANN and FR\xc3\x96SCHEL thermostabile. Also in their chemical behaviour certain differences can be demonstrated. Whereas the substance studied by K\xc3\x96CKEMANN is soluble in ether, this is not the case with the inhibiting substance found by OPPENHEIMER in tomatoes.

Description: While studying the parasitic copepods of the Dutch Waddensea, at the Zoological Station Den Helder, I came across a species of Bomolochus from the gills of the Black Sole, Solea solea (L.). Except for the second leg, the various appendages resembled those of B. soleae CLAUS, as figured by TH. & A. SCOTT in their Ray Society Monograph (1912\xe2\x80\x9413). According to them, the endopod of the second leg has narrow joints, like the exopod. They stated that the second and third leg have about the same structure. In my material, however, the endopod of the second leg has widened joints; second and third legs have, therefore, quite a different aspect.\nOf TH. and A. SCOTT\xe2\x80\x99S material, 2 samples remained**) in the collections of the British Museum (Natural History), Londen. The specimens proved to be quite distinct from the Dutch ones, differing not only in the structure of the second leg, but also in several other, less striking, characters.

Description: Among the notes and collections that came to the Zoological Museum, Amsterdam, after Dr H. C. REDEKE\xe2\x80\x99s death in 1945, I found an entirely completed manuscript, dealing with a new D\xe2\x80\x99Arcythompsonia found in a canal at Den Helder (Netherlands). This is the species cited as nomen nudum by KARL LANG (1948, p. 274), in his \xe2\x80\x9cMonographie der Harpacticiden\xe2\x80\x9d.\nPencil drawings and two coloured pictures relating to this species were found among REDEKE\xe2\x80\x99s papers. They have been redrawn in China Ink, without important alterations. The original slides used for these illustrations were found among the temporary glycerin mounts of Dr REDEKE; they are now \xe2\x80\x94 in a rather bad condition of course \xe2\x80\x94 in the Zoological Museum, with the collection number Co. 105,002.

Description: I have to thank Dr. H. C. Bl\xc3\xb6te of the Leiden Museum of Natural History for his kindness to entrust me with a number of Carabidae from Indonesia for identification. A few species appear to be new to science; the descriptions follow below. One genus, Horniulus Jedl., is new to the whole of the Malay Archipelago, and another, Bembidion Latr., is new to Sumatra. Of the latter genus there are already a couple of species known from Java.\nI am much obliged to Mr. E. B. Britton of the British Museum, who carefully compared a few species with specimens in the collections of the British Museum and in Andrewes\' collections.\nThe type specimens are in the Leiden Museum.\nOxygnathopsis gen. nov. (fig. 1 f) (Andrewes (1938, p. 196) described Oxygnathus javanus upon a single specimen from Java. With regard to the proper genus Andrewes was not absolutely sure because of a number of important differences, but before introducing a new genus he preferred to wait till more material was available. In the sending of the Leiden Museum I found a second specimen, which shows the same characteristics as the specimen described by Andrewes, so that in my opinion a new genus is desirable.\nThe two genera are to be distinguished as follows: 1 (2) Head with the clypeus bisetose, two setae on each side over the eyes, facial carinae and sulci present; prothorax with two lateral setae on each side. Range: Assam and Burma.........Oxygnathus Dej. 2 (1) Clypeus without setae, one supra-orbital seta, the front seta is wanting, no facial Fig. 1. a, Coptodera flavipes sp. n., left elytron; b, Horniulus quadrimaculatus sp. n.,

Description: Unter dem Titel \xe2\x80\x9eCatalogue syst\xc3\xa9matique du cabinet d\'ornithologie et de la collection de quadrumanes de Crd. Jb. Temminck. Avec une courte description des oiseaux non-d\xc3\xa9crits ... \xc3\xa0 Amsterdam, chez C. Sepp Jansz.\nMDCCCVH" gab der bald dreissigj\xc3\xa4hrige C. J. Temminck ein B\xc3\xbcchlein heraus, das dem Historiker der Ornithologie manch willkommenen Aufschluss erteilt. Der Autor selber hat in sp\xc3\xa4teren Jahren diese seine erste Ver\xc3\xb6ffentlichung nicht mehr erw\xc3\xa4hnt. Wegen ihrer Seltenheit ist sie den meisten Ornithologen der Folgezeit unbekannt geblieben, und einzig Hartlaub hat sich der Aufgabe unterzogen sie genauer zu studieren und die vielen neuen Vogelarten zu deuten, die Temminck im Catalogue" zwar sorgf\xc3\xa4ltig beschrieben, aber nur mit franz\xc3\xb6sischen Namen belegt hatte1). Bei diesem schwierigen Bem\xc3\xbchen machte Hartlaub die Entdeckung, dass Vieillot den \xe2\x80\x9eCatalogue" seines Widersachers Temminck stillschweigend ausgebeutet hat, als er danach trachtete im \xe2\x80\x9eNouveau dictionnaire d\'histoire naturelle, appliqu\xc3\xa9e aux arts" (1816-1819) alle bekannten Vogelarten zusammenzustellen.\nVieillot ging dabei so vor, dass er die Diagnosen Temmincks mit geringf\xc3\xbcgigen Ver\xc3\xa4nderungen wiederholte und den franz\xc3\xb6sischen Namen, den Temminck seinen neuen Arten gegeben hatte, durch eine bin\xc3\xa4re Benennung ersetzte.\nAls C. J. Temminck Ende 1806 den \xe2\x80\x9eCatalogue" abschloss, war seine Sammlung durch Kauf und Tausch auf 1072 Vogelarten angewachsen. Sein Vater Jacob Temminck hatte sie um 1770 gegriindet und sie von 1785 ab besonders mit Hilfe von Francois LevaiUant ansehnlich vergrossert. Zur Kennzeichnung ihrer Anfange mogen hier zwei Zitate aus meiner \xe2\x80\x9eEntwicklung der Ornithologie" (Berlin, 1951) wiederholt werden.

Description: COPROMORPHIDAE\nMeyrick, 1905, Journ. Bombay Nat. Hist. Soc, vol. 16, p. 606.\nThis small family represents a natural group with clearly marked characters, and is easy of descrimination. It inhabits tropical regions of Asia and extends through the Papuan region over the whole Pacific. The last mentioned region might be the country of origin of this group, as genera with peculiar and possibly archaic characters have been recorded from the Pacific Islands; some of those species are distinguished by an exceptionally large size.\nOne of the interesting points with regard to the family is its possible place in the system. The long-ciliate or pectinate antennae, the neuration, and the complicated genital apparatus of the male seem to indicate an affinity with the Tineoidea. The general facies, however, is divergent to some extent, while the presence of a cubital pecten on the hind wings fundamentally discriminates this family from all the Tineoidea sensu stricto. When describing the family, Meyrick suggested that the cubital pecten might point towards an affinity with the Tortricoidea ; this relation, however, is not supported by any other characters. He further surmised that the Copromorphidae would be nearest allied to the Xyloryctidae ; in my opinion this surmise is devoid of any ground. Later Meyrick tried to combine with the Copromorphidae two other groups of "Tineina" that also are in possession of a cubital pecten, viz., the family Orneodidae, and the genus Hypertropha Meyr. The relation of the former with the Copromorphidae, however, is problematic, and deserves further proofs, while Hypertropha has in my opinion nothing in common with the family concerned, except for the

Description: In 1857 and 1860, Milne Edwards and Haime listed 9 species of Stylasterlna known to occur in the Pacific region, including "Allopora (Stylaster) infundibulifera", a species which later, as Amphelia infundibulifera (Lamarck), was to be classified in the Madreporaria (Scleractinia). Moseley (1880), who compiled a list of all the species of the group at that time known, recorded 22 species occurring in the Pacific region. To these Hickson & England (1905) added 14 new species, 4 new formae ("facies"), and 4 records of species up to that time not known from the Pacific; Fisher (1931, 1938) described 14 new species, 4 new subspecies, and 1 new forma ; Broch (1932, 1935, 1936, 1942) described 14 new species and 9 new formae. This brings the total of the species and forms known to occur in the Pacific up to 86. To these must be added the corals of the group described by various authors cited at the end of the present paper, which results in 127 Stylasterina of the Pacific regarded as separate species or formae. These are listed below, alphabetically in the different genera, each name followed by one or more numbers in brackets indicating the regions of the Pacific in which the species or formae are known to occur. The limits of the regions are more or less arbitrary, some might have been divided into smaller regions, others might have been combined to larger regions, but the here accepted regions on the whole appear to form a basis for the discussions in the following pages. The regions in which the Pacific area for the present purposes has been divided are: I, Alaska, Aleutian Islands, Bering Sea; 2, Okhotsk Sea; 3, Japan and adjacent seas; 4, Philippine Islands and Sulu Sea; 5, East Indian Archipelago; 6, New Guinea and Torres Strait; 7, Solomon Islands; 8, New

Description: On March 7, 1953 the Rijksherbarium suffered a severe loss by the sudden death of its honorary co-operator Dr. D. F. van Slooten, the wellknown specialist particularly of Dipterocarpaceae. To honour his memory the following lines may serve as an obituary note.\nDirk Fok van Slooten was born in Amersfoort on 17 March 1891. In the local gymnasium his biology teacher was the later Prof. A. Pulle, who was again his master at the University of Utrecht where he was matriculated in 1910. His doctor\xe2\x80\x99s thesis of 1919 was dealing with the Combretaceae and Flacourtiaceae of the Dutch East Indies.

Description: Argostemma Wall. (type species: A. verticillatum Wall.).\nThis large Old World genus, comprising about 240 binomials of which, ca 70-80 will prove to be distinct species, has been almost unanimously left undivided. Exceptions are Reinwardt who in 1825 created the genus Pomangium, independently of Wallich (1824) and Ridley who in 1927 based the genus Argostemmella on two Bornean species of Argostemma. My revision (in msc.) of Argostemma occurring in Malaysia confirmed the common view that there is no reason for splitting up this genus. However, several subdivisions (sections) can reasonably be accepted. As those sections mostly represent well-delimited taxa in connection with a rather evident distribution of their own, I propose here the following 5 sections for Argostemma. It should be borne in mind that I have examined almost all extra-Mallaysian species too.

Description: On a private collecting trip to the Netherlands Antilles, in the winter of 1948\xe2\x80\x941949, I had the opportunity of studying an infestation of the sapodilla, caused by a well-known kind of fruitfly, Anastrepha serpentina, which, however, has never before been reported from these islands. The identification was kindly confirmed by E. McC. Callan, Imperial College of Tropical Agriculture, Trinidad; specimens were compared by him with material named by A. Stone, deposited with the collections of the I.C.T.A.\nMy grateful thanks are due to the Department of Agriculture of the Netherlands Antilles for giving a financial support which made entomological work possible, and especially to Agricultural Superintendent B. A. Bitter, for putting at my disposal the facilities of the Agricultural and Experimental Gardens at Cas Cor\xc3\xa1.

Description: The small collection of tiger-beetles, belonging to the genus Cicindela, which is the subject of this paper, was made by Dr P. Wagenaar Hummelinck during his visits to the Lesser Antilles and the adjacent South American mainland coast in 1936-\xe2\x80\x9937 and 1948-\xe2\x80\x9949.\nThe greater part of the material has been deposited at the \xe2\x80\x9eZo\xc3\xb6logisch Museum\xe2\x80\x9d of Amsterdam and the \xe2\x80\x9eRijksmuseum van Natuurlijke Historie\xe2\x80\x9d at Leiden. Some specimens (14 C. auraria, 10 C. graphiptera and 9 C. trifasciata) were presented to the collections of the American Museum of Natural History, British Museum, Deutsches Entomologisches Institut, Hope Department of Entomology at Oxford, The Imperial College of Tropical Agriculture in Trinidad, Institut Royal des Sciences Naturelles de Belgique at Brussel, Mus\xc3\xa9e National d\xe2\x80\x99Histoire Naturelle at Paris, Natural History Museum of Jamaica at Kingston, United States National Museum, and the Zoological Museum (including the collection E. Suenson) at Copenhagen, whose keepers kindly entrusted me with some material included in this study. The specimens from the U.S. Nat. Mus. were presented to Amsterdam, those from the Amer. Mus. to Leiden.

Description: Among the material brought together in the West Indies by Dr P. Wagenaar Hummelinck there are some coral colonies of the genus Tubastraea that are interesting from various points of view, in the first place because this genus of Madreporaria has but recently become known to occur in the West Indies. Vaughan & Wells (1943, p. 239) note as range of distribution of the genus Panam\xc3\xa1, Indo-Pacific, Gulf of Guinea, and the West Indies. As I did not succeed in finding data in the previous literature on the occurrence of Tubastraea in the West Indian area, I wrote to Dr J. W. Wells, Cornell University, Ithaca, New York, who kindly informed me that the statement given above was based on otherwise unpublished recent finds of material from off Puerto Rico, whilst later a specimen was received from Cura\xc3\xa7ao. Moreover, the genus is mentioned in the Taxonomic Key to Genera of Living Western Atlantic Corals in Smith (1948, p. 108).\nVaughan & Wells (l. c., pp. 238/239) define the genus Tubastraea with the following characters: \xe2\x80\x9cLike Endopsammia, but producing small subplocoid clumps by extratentacular budding from the edge-zone, polyps remaining organically united and with corallites united by some coenenchyme and feeble costae. Columella feeble, but occasionally well developed.\xe2\x80\x9d As the authors refer to the genus Endopsammia, the characters of the latter genus also may be cited here (l. c., p. 238): \xe2\x80\x9cSimple, subcylindrical, nonepithecate, fixed by broad base. Wall thin, costate. Septa thin, arranged according to Pourtal\xc3\xa8s plan only in early stages, later appearing normal. Columella small and spongy or scarcely developed.\xe2\x80\x9d

Description: While examining a number of Limnoria lignorum (Rathke) living in a piece of cork washed ashore at Zandvoort (Netherlands), Mr. J. H. Stock found attached on abdomen and legs of these Isopods some Ostracods belonging to the family of Cytheridae. As the specimens, though having characters in common with some known genera, differ markedly, I propose to establish 2 new genera, viz. Aspidoconcha and Redekea.\nDr. W. Vervoort [1950, Harrietella simulans (T. Scott, 1894). A commensal Copepod on Limnoria lignorum (Rathke), Zool. Meded. 30 (20) mentioned the presence of Ostracods on Limnoria lignorum collected by Mr. J. A. W. Lucas in a piece of wood washed ashore near Katwijk. Through the kindness of Prof. Dr. H. Boschma, director of the Leiden Museum of Natural History I was able to study the Ostracods. These proved to belong to the same species as the specimens of Aspidoconcha found by Mr. Stock. In vain I examined the autochthonous Limnoria lignorum material in the collections of the Zoological Museum, Amsterdam, for the presence of Ostracods.

Description: In 1947, Bishop was the first to pay attention to the occurrence of the barnacle Elminius modestus Darwin in British waters. This barnacle, which is a native of the coasts of southern and eastern Australia and New Zealand, i.e. of the temperate seas of the southern hemisphere, had been found by him in great quantities on test-panels in Chichester Harbour in July 1945. Soon after, several other records were published. Crisp and Chipperfield (1948) mentioned a number of localities; Elminius modestus appeared to be already widely distributed along the British coast (see fig. 1). Stubbings (1950) had the disposal of data of 1944 and from the size of the collected specimens he concluded, that Elminius must have occurred in Portsmouth as early as 1943. According to Knight-Jones (1948), Elminius had by then become a pest in the oysterbeds off Essex. Boschma (1948) recorded the barnacle from the Dutch coast where it had first been found in 1946.\nMeanwhile, Elminius modestus has enlarged its area considerably, in the British waters as well as along the continental coast. This paper will chiefly deal with the immigration, the dissemination and the habitat of Elminius modestus along the continental coast.

Description: Toen ik deze studie begon was het mijn bedoeling de verspreiding van de Clausiliidae over de Indo-Australische Archipel te toetsen aan de van andere diergroepen bekende zo\xc3\xb6geographische gegevens. Al spoedig bleek echter, dat eerst een systematische bewerking noodzakelijk zou zijn om als basis voor verder onderzoek te kunnen dienen. Mijn doelstelling is dus gewijzigd in: het geven van een zo volledig mogelijk overzicht van de in de Indo-Australische Archipel voorkomende Clausiliidae, gebaseerd op literatuur-gegevens, museum-materiaal en recente, mede op mijn verzoek gedane vondsten. De thans uit de bewerking ter beschikking gekomen zo\xc3\xb6geographische gegevens zijn helaas beneden mijn verwachting gebleven. Daardoor valt de klemtoon van deze studie meer op de systematiek, waarbij vele nieuwe gegevens op het gebied van morphologie, anatomie en biologie aan het licht kwamen. Indien iedere verzamelaar van het bestudeerde materiaal zijn vondsten echter volledig had ge\xc3\xa9tiketteerd, waren nog veel meer bijzonderheden bekend geworden en waren die vondsten veel waardevoller geweest. Hieronder volgt een korte uiteenzetting van wat in de opeenvolgende hoofdstukken behandeld wordt.\nHOOFDSTUK I bevat een inleiding over de begrenzing van het onderzoek en vermeldt tevens van welke musea en particulieren materiaal voor studie is verkregen. De soorten van de familia Clausiliidae, die in de Indo- Australische Archipel voorkomen behoren alle tot de subfamilia Phaedusinae, die in hoofdzaak over Oost-Azi\xc3\xab is verspreid. Het bestudeerde gebied omvat de Maleise Archipel met inbegrip van het schiereiland Malakka en de Philippijnen.\nHOOFDSTUK II geeft een overzicht van de Phaedusinae men vindt er algemene gegevens over het voorkomen, over het uiterlijk van de slak, over de bouw van de schelp en over de anatomie van de voor de systematiek belangrijke organen. Er blijkt uit, dat de dieren vooral in heuvel- en bergland voorkomen, dat de spoelvormige tot penvormige schelp zeer ingewikkeld van bouw is en steeds kan worden afgesloten door middel van een sluitplaatje, dat in de laatste winding als een deur heen en weer kan bewegen.\nVerder worden de radula en de ingewikkeld gebouwde genitaal-organen beschreven. De slakken zijn hermaphrodiet, het is echter niet zeker of wederzijdse bevruchting plaats vindt. Ze leggen eieren of brengen jongen ter wereld, die reeds een schelpje met 2 tot 3 windingen bezitten.\nHOOFDSTUK III geeft een overzicht van de geschiedenis van de studie van de Zuidoost-Aziatische Phaedusinae. Daaruit blijkt, dat tot nu toe eigenlijk alleen aandacht aan de bouw van de schelpen, aan de systematiek en aan de verspreiding is besteed. Slechts in uitzonderingsgevallen vindt men bij de vroegere auteurs iets over de anatomie van een slakkensoort (3 x) of over het biotoop vermeld. De morphologie van de schelpen treft men in hoofdzaak aan in de vorm van onvolledige soortbeschrijvingen. Veelal zijn de inwendige bouw van de schelp en het clausilium niet beschreven.\nHOOFDSTUK IV behandelt het systematische gedeelte en begint met een opsomming van de 54 in het gebied aangetroffen soorten en ondersoorten, verdeeld over 6 genera. Negen soorten of ondersoorten zijn door mij voor het eerst beschreven.\nVervolgens vindt men een determinatie-tabel tot de genera en daarna worden de genera met de ertoe behorende soorten behandeld.\nDe behandeling van een genus begint steeds met de karakteristiek en met een determinatie-tabel tot de soorten. Daarna wordt soort voor soort volledig beschreven. Hierbij heeft in de meeste gevallen het holotype als uitgangspunt voor de beschrijving kunnen dienen. Ik heb tekeningen gemaakt van bijna alle soorten en ondersoorten, zoveel mogelijk naar de holotypen. Na de morphologische beschrijving van de schelp volgt een kort overzicht van de gepubliceerde gegevens op dit gebied. Daarna wordt zoo mogelijk de anatomie behandeld en vervolgens de verspreiding aan de hand van literatuurgegevens. Tenslotte worden alle door mij bestudeerde monsters, welke van behoorlijke vindplaatsgegevens voorzien waren, genoemd met opgave van minimum en maximum afmetingen en van de gemiddelden.\nDit hoofdstuk geeft dus een volledig overzicht van het bestudeerde materiaal in al zijn facetten.\nHOOFDSTUK V vat de in het vorige hoofdstuk verkregen gegevens samen. In de eerste plaats wordt in een systematisch gedeelte de huidige opvatting over de systematiek der Indo-Australische Phaedusinae uiteengezet. Daarna geef ik aan welke wijzigingen door mij in het door THIELE gepubliceerde systeem noodzakelijk worden geacht. Dit betreft in hoofdzaak twee punten, nl. 1. Acrophaedusa (type A. cornea P.HIL.), behoort niet als subgenus onder Hemiphaedusa en 2. Phaedusa (type Ph. corticina PFR.) en Pseudonenia (type Ps. javana PFR.) zijn niet synonym, doch duidelijk te scheiden genera.\nIn het bestudeerde gebied komen vertegenwoordigers voor van de volgende 6 genera: Phaedusa, Pseudonenia, Euphaedusa, Paraphaedusa, Acrophaedusa en Hemiphaedusa.\nVoor het combineren van deze genera tot groepen van hoger orde acht ik de tijd nog niet gekomen. Vervolgens worden de voor de systematiek meest belangrijke kenmerken genoemd en hun aanwezigheid in de zes genera wordt besproken. Hierbij is bij de morphologische kenmerken vooral aandacht besteed aan de inwendige bouw van de schelpen, d.w.z. aan de lamellae, plicae en aan het clausilium. Voorts worden enige anatomische en biologische eigenschappen behandeld; tot nu toe was daarover bijna niets bekend. Een korte bespreking van de genera en de daartoe behorende soorten sluit hierbij aan. Vervolgens eist de oecologie van de soorten de aandacht. De gegevens op dit gebied zijn nog steeds zeer onvolledig, ook al heb ik het aantal bekende feiten bijna kunnen verdubbelen. Men vindt onder de aanwezige soorten zowel bodembewoners als boombewoners.\nTenslotte wordt de verspreiding behandeld. Tabel I geeft de verspreiding van de soorten en ondersoorten over de eilanden aan. Daaruit blijkt, dat vier genera (Phaedusa, Pseudonenia, Acrophaedusa en Hemiphaedusa) binnen het bestudeerde gebied gebonden zijn aan het Sunda-plat, terwijl de twee andere genera (Euphaedusa en Paraphaedusa) in hoofdzaak beperkt zijn tot de eilanden tussen het Sunda- en het Sahul-plat. De soorten, die op het Sunda-plat voorkomen, hebben hun naaste verwanten in Achter-Indi\xc3\xab, zodat de immigratie wel van daaruit moet hebben plaats gehad. De soorten van de beide andere genera hebben hun naaste verwanten in China, zij moeten de Archipel wel via de Philippijnen hebben bereikt. De zo\xc3\xb6geographische conclusies, verkregen uit de verspreiding van de Clausiliidae over het Indo-Australische gebied, ondersteunen in het algemeen de bestaande, op andere diergroepen gebaseerde opvattingen.

Description: The following pages contain a first report on the fishes collected by Dr.\nD. C. Geijskes and Mr. P. H. Creutzberg during the recent expedition to Dutch Guiana.\nA deplorable lack of time caused by the necessity to temporarily divert my attention from the present field of ichthyological research, compels me to publish these results before actually having finished the investigation of this rich and interesting collection.\nIn consequence of this, the present paper concerns a part of the actual material only, and, though it includes in number the major part, a report on specimens belonging to some of the most interesting groups has to be postponed.\nFor convenience\' sake, the species recorded in the present paper have been arranged in the same order as used by Eigenmann (1912) and Boeseman (1952). Of all species the standard length is given, and generally the total length. The majority of the localities are in the neighbourhood of Paramaribo, or along the lower parts of the Marowini River. G. stands for Geijskes, C. for Creutzberg.\nWhenever available, additional data concerning further recently identified material are given: of this part of the material generally the total length is given only.\nThe following new species are described: Heptapterus bleekeri nov. spec.\nCentromochlus creutzbergi nov. spec.\nHarttia crassicauda nov. spec.\nPyrrhulina stoli nov. spec.

Description: The days of big game seem to be numbered. Lists of mammals recently extinct are growing longer and longer and many more species are in danger of extinction. Of course, the last world war has hastened the fate of several species of animals. Eastern Asia and the Pacific region without doubt have suffered most in this respect. For example, the number of Javanese Rhinoceros, Rhinoceros sondaicus DESM., has diminished to such extent that survival seems hardly possible, owing to the aftermath of the Pacific war, which put out of action all painstaking measures of protection.\nEven before the last war two Asiatic species of deer were on the list of nearly extinct animals, viz. the Milu and Schomburgk\xe2\x80\x99s Deer.

Description: Sherborn (1899) very ably discussed the four editions of Lacep\xc3\xa8de\'s "Tableaux des Mammif\xc3\xa8res et des Oiseaux" that were known to him, and made the complicated history of these publications clear. To these four editions we now can add two that evidently were not known to Sherborn, one of which must be exceedingly rare. In the following lines the six editions are discussed in chronological order; editions I, III, IV, and V have been dealt with by Sherborn, II and VI are those that we recently became acquainted with.\nEdition I (published between January 1 and September 22, 1799). The original "Tableaux" were published in Lacep\xc3\xa8de\'s "Discours d\'ouverture et de cl\xc3\xb4ture du cours d\'histoire naturelle Donn\xc3\xa9 dans le Mus\xc3\xa9um national d\'Histoire naturelle, l\'an VII de la R\xc3\xa9publique, et Tableaux m\xc3\xa9thodiques des mammif\xc3\xa8res et des oiseaux" a paper, in-4, issued "\xc3\xa0 Paris chez Plassan, Imprimeur-Libraire. L\'an VII de la R\xc3\xa9publique." This publication consists of three parts. The first (4 pp., pp. 1-55, 1 p.) contains the actual "Discours". The second is the "Tableau des divisions, sous-divisions, ordres et genres des mammif\xc3\xa8res", pp. 1-18; the third is "Tableau des sous-classes, divisions, sous-divisions, ordres et genres des oiseaux", pp. 1-20. This edition has been fully dealt with by Sherborn (1899).\nEdition II (published between September 23 and December 31, 1800).\nThis second edition was published as an appendix to "S\xc3\xa9ances / des \xc3\xa9coles normales, / recueillies / par des st\xc3\xa9nographes, / et revues / par les professeurs. / Nouvelle \xc3\xa9dition. / Tome huiti\xc3\xa8me." published at "Paris, / \xc3\xa0 l\'imprimerie du cercle-social. / (1800.) / An 9 de la R\xc3\xa9publique Fran\xc3\xa7aise.", it is in-8.

Description: From the Aroe Islands, four different species of White-eyes were recorded with more or less certainty in literature (Salvadori, 1881; Finsch, 1901; Stresemann, 1931). Mayr (1941), the latest revisor, lists three species, viz., Zosterops novaeguineae subsp., Z. minor sharpei, and Z. chloris chloris (now named Z. lutca chloris, cf. Mayr, 1944).\nThe presence in the Leiden Museum of a small series (6 specimens) of Z. novaeguineae from the Aroe Islands, and of the type specimen of Z. sharpei, enables me to discuss these forms more fully than hitherto has been possible.\nZosterops novaeguineae Salvadori As at Leiden no material for comparison was available, I sent 5 specimens from the Aroe Islands to the American Museum of Natural History, New York, where Dr. Mayr and Dr. Amadon compared them with series of Z. n. novaeguineae (7 adults) and Z. n. wuroi (4 adults and several immatures). I am very much indebted to Dr. Mayr and Dr. Amadon for their notes which enabled me to describe the Aroe specimens as a new race. Here follow the distinctive characters of the three races: Zosterops novaeguineae novaeguineae Salvadori, 1878. Eye-ring comparatively narrow; upper parts yellowish green; breast and flanks rather pale grey; throat and under tail coverts yellow. Wing: \xe2\x99\x82 59 (Salvadori\'s type specimen); \xe2\x99\x82 57 (Leiden Museum); \xe2\x99\x82\xe2\x99\x82 55, 56, 56, 58; \xe2\x99\x80\xe2\x99\x80 54, 56; sex ? 55 mm (American Museum). All specimens are from the Arfak Mountains, Vogelkop, Dutch New Guinea.\nZosterops novaeguineae wuroi Mayr & Rand, 1935. Eye-ring broad; upper parts much greener than in the nominate race (the original publication

Description: The fossil remains described in the present contribution as well as in previous numbers of this series (Hooijer, 1948a-c, 1949, 1953) were collected some years ago by Mr. H. R. van Heekeren at various localities in the Tjabeng\xc3\xa8 area, Sopeng district, about 100 km Northeast of Macassar in Southwestern Celebes. I owe the opportunity to study this material to Prof. Dr.\nA. J. Bernet Kempers, Head of the Dinas Purbakala R.I. at Djakarta, Java.\nThe elements to the Tjabeng\xc3\xa8 fauna described thus far from Mr. Van Heekeren\'s collection are a giant tortoise, a babirusa, an aberrant extinct suid (Celebochoerus), an anoa, and a pygmy elephantine, the molars of which are just a 50 per cent scale reduction of their homologues in Archidiskodon planifrons (Falconer et Cautley). While at first it seemed that the Pleistocene fauna of Celebes was not any richer than indicated above, subsequent consignments made it increasingly evident to me that the pygmy archidiskodont, Archidiskodon celebensis Hooijer (1949, 1953), was not the only proboscidean in the Tjabeng\xc3\xa8 fauna. Among the many specimens of Archidiskodon, mostly very fragmentary, there are a number of molar fragments of a more primitive type, stegodontine rather than elephantine in characters.\nStegodon is well represented in the Pleistocene of Southeast Asia; it occurs in the Siwaliks of India, and in Burma, Indo-China, China, Japan, Formosa, the Philippines, and Java. The material to be described below indicates that stegodonts have also reached the island of Celebes. Although the nature of the material does not permit of more than a generic determination it seems advisable to make the evidence available since it is improbable that additional material can be obtained under the present conditions.\nStegodon spec.

Description: In the majority of the papers dealing more or less extensively with Cetorhinus maximus the gill rakers (fanunculi) are correctly described and regarded as specifically characteristic, whilst in a number of other papers, e.g., de Blainville (1812), Vrolik (1826), and Tchang Si (1934) the gill rakers are not mentioned. This does not necessarily indicate that the specimens examined by the cited authors did not possess gill rakers, probably no definite search was made concerning the presence or absence of these parts.\nFrom 1821 till 1952 there stranded in the Netherlands or were brought ashore by fishermen 21 specimens of Cetorhinus maximus; of nine of these it was stated that they had gill rakers, four of these specimens proved to be without gill rakers, whilst of the other specimens no notes are given concerning these parts; the last named specimens will not be further dealt with in the present paper.\nDuring the years 1950 till 1952 special attention was paid to the condition of the gill rakers in the specimens of Cetorhinus maximus that became available. The following data could be obtained.\nAt Oostkapelle, island of Walcheren, province Zeeland, on April 11, 1950, Mr. P. J. van der Feen (Amsterdam) saw a male specimen with gill rakers; length 5.50 m. At Domburg, island of Walcheren, on October 23, 1950, he found a male specimen without gill rakers; length 3.37 m. Material of these two specimens has been preserved in the collections of the Zoological Museum at Amsterdam.\nAt the beach of the island of Texel, province North Holland, on September 5, 1951, Mr. I. Kristensen (Den Helder) found a female specimen with gill rakers; length 3.64 m.

Description: Within the Sapotaceae, the tribe of the Madhuceae presents a very homogeneous group. One point of view is to consider it a single polymorphous genus. The opposite opinion was expressed by Pierre, who distinguished a number of small genera, many on futile characters. Amongst those which stood later criticism is the genus Ganua which was, however, not published by Pierre but by Dubard (1907, 1908a, 201 and 1908b, 407), who adopted Pierre\xe2\x80\x99s Ms names and made use of his extensive annotations.\nThe name Ganua is derived from the word ganu, the native name for latex produced by a tree, \xe2\x80\x9cused for falsifying the valuable products of \xe2\x80\x98gutta terbu\xe2\x80\x99\xe2\x80\x9d (f. Errington de la Croix in schedula; cf p. 389).

Description: More than twenty years have elapsed since the senior author (H. J. Lam) recognized Haplolobus as a genus separate from Canarium. In the mean time much newly collected material has become available and in view of the intended revision for Flora Malesiana, the time has come to sum up our present knowledge.\nIt must be said first of all that this knowledge, in spite of a considerable progress, is still far from satisfactory. Not only is much of the material sterile, but the genus however small it is, more and more proves to be an extremely difficult one to handle in a practicable way. Whether or not this is due to its phylogenetic youth is of little consequence. The fact stands that we have to deal with a genus in which the subgeneric limits, even if intuitively recognizable to the experienced eye, are so evasive as to make it extremely difficult to show them clearly to the man of practice who has to work with the species and the names attributed to them.

Description: For many years the species problem in the Sacculinidae has been a matter of controversies. Kossmann\'s (1872) paper was of fundamental importance, because in his descriptions of a great number of new species, chiefly from the Philippine Islands, he derived the specific characters from the anatomical peculiarities as well as from the excrescences of the external cuticle. Later investigators for many years dealt with European material only, in which specific characters are far less apparent than in tropical Sacculinidae, so that their opinions concerning specific differences were often based on principles instead of on facts. This applies to the papers by Giard and Bonnier (Giard, 1886, 1887, 1888; Bonnier, 1887; Giard & Bonnier, 1887, 1890), in which the description of new species was regarded as sufficiently founded by a simple indication of the host, a procedure based on Giard\'s conviction of the "sp\xc3\xa9cificit\xc3\xa9 parasitaire", resulting from investigations on the Bopyridae.\nPreviously, Delage (1884) had proclaimed the opinion that the specific differences in the genus Sacculina were not sufficiently founded, and many years later Smith (1906), after remarking that he had tried in vain to find specific differences in the European forms of the genus, placed all the names of the later described species in the synonymy of Sacculina carcini Thomps. Gu\xc3\xa9rin-Ganivet (1911) described some new species of Sacculina based on characters of the internal anatomy; he did not investigate the excrescences of the external cuticle, which, e.g., in his species S. carpiliae and S. leptodiae, are of comparatively large size, consisting of groups of spines united on common basal parts. In one of Gu\xc3\xa9rin-Ganivet\'s figures (1911, Pl. I fig. 7, region of the mantle opening of Sacculina leptodiae, X 50) the excrescences of the external cuticle are faintly visible, but in the

Description: Since 1870 it has been a matter of debate among araneologists whether Meta mengei, described by Blackwall in that year, and separated by him from Meta segmentata (Clerck, 1757), is a real species or only a variety.\nIn order to find an answer to this question I give an historical survey of the views of the most important authors concerning this matter, followed by a discussion of the peculiarities generally regarded as characters distinguishing the two species or varieties, and a short account of my own investigations. 1757. Clerck figures and describes a species of spiders of which in the beginning of September he observed a great number ; he names it (Araneus) segmentatus. 1758. Linnaeus publishes a concise description of the same species and names it Aranea reticulata.\nFurther synonyms are to be found in Roewer (1942, pp. 915-916). 1862. Next to Meta segmentata, Westring distinguishes a species named by him Meta albimacula (Koch?), because in his opinion it is identical with Koch\'s Zilla albimacula. 1866. To his elaborate notes on M. segmentata, Menge adds an appendix about "eine neue art oder abart" (a new species or variety), referring to Westring\'s M. albimacula. He proves that this species is not identical with Koch\'s Zilla albimacula ( = Zilla diodia Walckenaer), but he considers the differences from M. segmentata not sufficiently marked for a separate species and regards it as "eine kleinere abart" (a smaller variety). 1870. Blackwall, who in 1864 had given an account and a drawing of Epeira inclinata (= M. segmentate), now elaborately describes the "variety

Toxopeus of Bandung, Java, sent me a specimen of Nyctalemon for identification, but neither with the help of our collection, nor with the current literature did I succeed in ascertaining the correct name of this insect. On the contrary it appeared that, though the described forms of this genus clearly were of different value, viz., partly good species, partly geographical subspecies representing these species in restricted areas, no satisfactory division of the genus into species and subspecies had been given. Thus, Seitz\' classification of the known forms into four species of which three are polytypic proved to make no sense. Therefore I resolved to study the genus more closely.\nIn the ensuing correspondence Toxopeus gave me the benefit of his experience by providing references to relevant literature and quotations from

Description: The present paper is the report on a collection of birds brought together during the expedition of the "Koninklijk Nederlandsch Aardrijkskundig Genootschap" to the Wissel Lake area in 1939. The zoologist of this expedition Prof. Dr. H. Boschma collected with the assistance of two mantris of the Buitenzorg Museum in this district from mid-August till mid-November, whilst also some collecting work was done at the Etna Bay.\nOf great importance was the help of the natives, who brought many birds that otherwise would have been difficult to obtain. Included in this report is a small collection made by Mr. J. P. K. van Eechoud in the same district in 1938. For permission to include it here I am indebted to the authorities of the Buitenzorg Museum. Though birds were only one of the many groups of animals that have been collected and no field notes have been made, this collection from an area where never has been collected before, is of much importance.\nThe collection contains, together with that of van Eechoud, 137 species of which 3 are new to New Guinea: Limicola falcinellus (migrant), Porzana pusilla and Megalurus gramineus.\nDescribed as new were 12 races of the following species : Rallus pectoralis, Porzana pusilla, Ptilinopus viridis, Ducula rufigaster, Malurus alboscapulatus, M egalurus gramineus, Phylloscopus trivirgatus, Pitohui kirrhocephalus, Neositta papuensis, Ptiloprora guisei, Dicaeum geelvinkianum, Lonchura castaneithorax (cf. Zool. Mededelingen, vol. 31, no. 22, July 11, 1952). Of these 9 originated from the Wissel Lake district, 1 from the Etna Bay, 1 from the southern slopes of the Snow Mountains, and 1 from Meos Num in the Geelvink Bay. Moreover an interesting hybrid between two species

Description: In this paper I intend to give a review of the genus Erycibe Roxb. in. which all the names published in the genus will be accounted for. The representatives from Malaysia have been dealt with more extensively in the revision of the genus in Flora Malesiana, Ser. I, Vol. 4, 4th instalment, 1953, pp. 404\xe2\x80\x94431. \xe2\x80\x94 Technical descriptions of new taxa have been published in another paper in Blumea 7, 1953, pp. 310\xe2\x80\x94319.\nIn the present paper the literature will be published more extensively than in Flora Malesiana; besides I have included citation of all type specimens. The extra-Malaysian species have been studied less extensively than the Malaysian ones, but as I have seen nearly all the types, some notes are inserted which will be, I hope, useful for future study of the genus. Particularly the specimens from the Indian Peninsula need closer study.

Description: Mr A.G.L. Adelbert was on short leave in Holland, Nov. 1951-April 1952; during Dr Donk\xe2\x80\x99s leave he has been appointed acting Keeper of the Herbarium Bogoriense.\nMr E.G. Browne assumed duty as Head of the Sarawak Forest Department, Jan. 1951.

Description: This important book, written by C.A. Gardner after 30 years of field study and several years of preparation, deals with 420 species of grasses of which over a hundred have been provided with a plate, by which the habit and important details are shown. Especially the drawings of various parts of the spikelets are very skilful, instructive, and of the utmost importance for students of critical genera.\nThere is an introductory part giving a general survey of the grass vegetation of W. Australia. It is a revelation to see that so many introduced and naturalised species had to be included; this striking invasion of 132 species affects a great change in the original vegetation.

Description: Dr R.C. Bakhuizen van den Brink Jr, Leyden, made a provisional revision of the genus Ophiorrhiza (Rubiaceae). Onwards of 1953 he will be working on the completion of Backer\xe2\x80\x99s Flora of Java.\nDr M.J. Baumann-Bodenheim who made a big collection of plants in New Caledonia during the past two years has been temporarily appointed at the Bot. Garden Z\xc3\xbcrich for the working out of this collection.

Description: Erismadelphus Mildbr. is remarkable because it is the only African genus of the Vochysiaceae, a family represented in tropical America by no less than 5 genera and 180 species. Erismadelphus was discovered in 1913 by Prof. J. MILDBREAD and has hitherto been represented by only one species: E. exsul Mildbr.\nRecent examination of the African collections has, however, revealed the existence of two other taxa. Unfortunately the type of E. exsul (Mildbraed s.n. from Elon, French Cameroons) was destroyed at Berlin during the 1939-45 war and no duplicates or cotypes are known to exist. In response to an enquiry Prof. MILDBREAD, to whom we are very grateful, informed one of us that in his view Corbisier 1362 from Eala in Belgian Congo was identical with his original type. Prof. MILDBRAED and KEAY have, in fact, together examined Corbisier 1362 in the Herbarium of the Jardin Botanique de l\xe2\x80\x99Etat at Bruxelles through the courtesy of Prof. ROBYNS. Duplicates of Corbisier 1362 are at Kew and Paris, they agree in every respect with MILDBRAED\xe2\x80\x99s original description and figure and we therefore propose that this specimen be adopted as the neotype (lectotype).

Description: Dr Kostermans points our attention to an article by W.H. de Vriese, in Tijd.Nat.Geschied. & Phys. 12, 1845, p.60, in which was noted that Hasskarl\xe2\x80\x99s Catalogue of the Botanic Gardens, Buitenzorg, was issued Oct. 1844.

Description: Tn the Malaysian area proper this small genus is represented by one species only (G. floribunda), but it seemed preferable to extend this work to a revision of the whole genus.\nThe species of this genus are not easily distinguishable when sterile and the identification of such specimens is all too often made on geographical evidence.

Description: The editor has received the first and second fascicle of a treatise of the vascular plants of West Virginia. According to the preface this flora, when complete, will present descriptions, illustrations, geographical data and other information, particularly of local interest for the approximately 2000 species found growing without cultivation in that State. The first part contains the Pteridophyta, Gymnospermae, and Monocotyledoneae, the second part the Dicotyledoneae, p.p. (Saururaceae-Leguminosae). Keys are given for genera and species. The rather short descriptions are completed by many for the greater part original line drawings. Nomenclature and sequence are those of the 8th edition of Gray\xe2\x80\x99s Manual, 1950, by M. L. Fernald.

Description: The list of Araceae published in 1906 by A. A. PULLE in his \xe2\x80\x9cEnumeration of the Vascular Plants known from Surinam\xe2\x80\x9d comprises 39 species belonging to 14 genera, the largest genera being Anthurium with 7 species and Philodendron with 12 species. It was found that one of these 39 species was included by mistake, for the specimen Wullschlaegel n. 1764, which is the type of Spathiphyllum blandum Schott, was erroneously assumed to have been collected in Suriname.\nAlready in 1908 TRESLING had collected a species that was not listed by PULLE, viz. Dieffenbachia picta (Lodd.) Schott.

Description: It is the fate of most historic personalities that in the course of time their work sinks almost completely into oblivion, and that the few lingering reminiscences of their achievements are transmitted to later generations in the form of second- or third-hand quotations, usually mixed with more or less anecdotic episodes from their life. It must be admitted that LINN\xc3\x89 occupies in this respect a comparatively favourable position, for most educated people will remember that they heard in their school days of at least three things which are credited to him, in the first place that he produced a classification of the plant kingdom which is based on the number of stamens and carpels, the so-called sexual system, in the second place that he was the first who consistently applied the binomial nomenclature, i.e. the custom to designate an organism by a combination of two names, viz. a generic and a specific one, and thirdly that he was the originator of the pronouncement \xe2\x80\x9cSpecies to numeramus quot diversae formae in principio sunt creatae\xe2\x80\x9d (We count so many species as in the beginning different forms were created). Other achievements of LINN\xc3\x89 may have been of greater importance, but it are these three things for which he is most generally remembered.\nThe pronouncement quoted above, which means that the groups of individuals which form the species are descended from ancestors that owed their origin to an act of creation, derives its historic importance from the part it played in the debates on the theory of evolution. As it implies that the species are constant, it became the watchword of the antagonists. It is, however, rather strange that this pronouncement has so often been quoted, for it is found in LINN\xc3\x89\xe2\x80\x99s earlier works only, and was in the later ones replaced by another statement that flatly denies the constancy of the species.

Description: It is remarkable that, though on several occasions rather full accounts have been given of the history and activities of the Botanic Gardens at Bogor (Buitenzorg), \xe2\x80\x9dKebun Raya Indonesia\xe2\x80\x9d, up till now nothing comparable has been published on it\xe2\x80\x99s Mountain Garden Tjibodas.\nThis is the more striking as the establishment of a guesthouse annex biological laboratory in the Mountain Gardens by Melchior Treub, in 1890, which gave Tjibodas a definite claim to be recognized as a scientific institution, has sometimes been declared to be one of the greatest achievements in Treub\xe2\x80\x99s period of office.

Description: Centenary of the Kew Herbarium and Library. If we are well informed the centenary of the Herbarium\xe2\x80\x9d and Library of the famous Royal Botanic Gardens, Kew, occurs in 1953 and will be informally celebrated by an Exhibition in the Herbarium on the 8th and 9th of May, 1953, which will, we assume, be attended by many of the countless friends of this Mekka of Botany and in honour of the unsurpassed service which it renders to botanists all over the world.\nIndonesian timbers. A sample proof sheet was received of a book to be issued by the Indonesian Forest Research Station at Bogor. This will comprise a botanical treatment of about 400 of the most important timbers of Indonesia. Each species is to occupy 4 pages, viz a full page drawing, and one page for the text in 3 languages: Indonesian, Dutch, and English. Each description consists of the name and synonyms, preferent vernacular name, other vernacular names, geographical distribution, habitat circumscription, habit description, technical-botanical description, and notes. No mention is made of the anatomical characters of the wood; these will be published in a separate book which is prepared simultaneously. The book will probably be finished in 1956.
