    Description: Unter dem mir von Herrn Dr. F. P. Koumans freundlichst überlassenen Hemirhamphiden-Material des Rijksmuseum van Natuurlijke Historie te Leiden ist eine Serie einer neuen Zenarchopterus-Art, die ich wegen der Form der Anale beim erwachsenen Männchen bezeichne als: Zenarchopterus xiphophorus nov. spec. Mus. Leiden:Belawan-Deli, Sumatra; 4 ♂ von 12.5, 12.5, 13.0, 13.5 cm; 2 ♀ von 13.0, 17.0 cm. ♂ D 15; A 10—11; P 11; V 6; Sq. 1. ca. 40. ♀ D 14; A 11—12; P 11; V 6; Sq. 1. ca. 40. Oberschnabel etwas breiter als lang; Länge sechs- bis siebenmal im Schnabelfortsatz enthalten. Analpapille beim ♂ gross mit besonderer Spitze, nicht beschuppt, ♀ ohne. Iriszipfel nicht mehr zu finden. ♂: Vierter D-Strahl verbreitert und um mehr als die Flossenhöhe verlängert; der 4. Strahl ist so stark gebogen, dass — wenigstens bei den erwachsenen konservierten Tieren — der Klunker des Strahlenendes neben dem Silberstreifen an der Körperseite liegt. ♂ A dreiteilig, im vorderen Teil 5 dünne Gliederstrahlen; 6. Strahl stark verdickt, verbreitert, gefiedert und etwa viermal so lang wie der 5., sodass das Ende des 6. bei erwachsenen ♂ noch weit über den Hinterrand der Caudale hinweg ragt. Bei den 12.5 cm langen ♂ überragt der 6. Strahl das C-Ende noch nicht, wohl aber die C-Basis. Im Gegensatz zu Z. brevirostris Gthr. legt sich bei der neuen Art der 6. Strahl nicht neben die Körperseite, sondern bleibt in der Flossenebene unterhalb der Unterkante des Fisches. Hinter dem verlängerten und verbreiterten 6. Strahl folgen der 7.—10. (11.) A-Strahl als selbständiges Flösschen von

    Artificial key to the Orchid Genera of the Netherlands Indies, together with those of New Guinea, the Malay Peninsula and the Philippines (1934)
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 1 no. 1, pp. 194-215
    Details
    Publication Date: 2024-01-12
    Description: It is often a very difficult task for the many amateurs and cultivators of Orchids, and I may add hardly in a less degree to students of the flora of the Netherlands Indies, to classify properly the Orchids they come across. The reason for this lies not only in the fact that the generic characters in this large order are often not easily distinguished, but also in the fact that nearly every genus counts a certain number of more or less anomalous species, so that the limits between the genera are not always easy to determine. Besides, many descriptions are, even in principal points, incomplete, either because the authors had no sufficiently good material at their disposal, or because they did not take the trouble to draw up good descriptions. For these reasons species are unavoidably often placed into a wrong genus, to which fact a great deal of the prevailing confusion is to be ascribed.\nAlthough in the course of years many questions have been solved, it cannot be denied that new problems did arise. Only very accurate and complete descriptions, the best, of course, elucidated by figures after fresh or alcohol material, can put us in a position to decrease these difficulties.

    Editorial (1934)
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 1 no. 1, pp. 4-6
    Details
    Publication Date: 2024-01-12
    Description: Twenty-four years have elapsed since the Institution, then called \xe2\x80\x9e\xe2\x80\x99s Rijks Herbarium\xe2\x80\x9d, started a series of papers entitled \xe2\x80\x9eMededeelingen van \xe2\x80\x99s Rijks Herbarium, Leiden\xe2\x80\x9d. Exactly 70 numbers have been issued between 1910 and 1933 inclusive, most of them under the directorate of Dr J. W. C. GOETHART, to whom many thanks are due for his arduous work and his many cares in favour of these publications.\nAfter the undersigned, oil October 2nd, 1933, had taken over the directorate of the Rijksherbarium from the acting director, Dr W. A. GODDIJN, he could start realizing some projects which, in relation to his tropical experience, seemed more or less promising. First of all it was obvious that the Rijksherbarium should, to a greater degree than had been possible during the last decennia, contribute to the investigation of the flora of the Netherlands Indies. Effectuating this idea seems possible by a closer collaboration with the Herbarium of the Botanical Gardens of Buitenzorg, Java, with whose officers it was my privilege to come to an agreement before I left the colony. Another point to be considered was the establishment of a closer contact with the State University at Leiden, the herbarium of which has been united with the Rijksherbarium since 1832. This contact has been rather loose in various periods of the existence of the Rijksherbarium and in developing it, the details will have to be carefully studied and sounded, lest the archive value of the collection should be decreased. Without taking any risk as to this point, which cannot be fully compensated by the advantages, it is thought that a closer contact is both possible and desirable, as it may further two important interests: in the first place it is intended to exploit and to peruse both more intensively and more extensively the treasures of this Herbarium, and secondly an attempt will be made to increase the number of students in the field of investigation that is allotted to the institution.

    Materials towards a study of the Flora of the island of New Guinea (1934)
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 1 no. 1, pp. 115-159
    Details
    Publication Date: 2024-01-12
    Description: It has so often been emphasized that the flora of large tropical islands like New Guinea is still very imperfect, that the impression has been established that the data available should be in a state unapt to produce a conspectus or to procure valuable conclusions. Though it is certainly true that there are still immense plots of land entirely unknown from a botanical (or any other) point of view, and that we know but a part (but most probably more than one half) of the Papuan species of Pteridophytes and Spermatophytes, I am inclined to think that it is more than anything else the scattered nature of those data, that prevented us from realizing their intrinsic value. The time has come, I think, to pauze and to realize what has been done in the past years; to arrange the many unco\xc3\xb6rdinated data in such an order that, on one hand a comprehensive view may be obtained of what has come to our knowledge and on the other hand the gaps may become apparent. In this way it may be expected beforehand, that our present knowledge, however scanty it may be, may enable us to form some provisional conclusions of not too slight an importance and of not too mean reliability. Especially as far as floristics are concerned it is obvious that, for instance, consideration of one half of a flora will lead to practically the same conclusions as the whole flora would.\nIn this investigation that is meant to be amplified by more detailed studies later on, I have, first of all, compiled an enumeration of the more important collectors and also of books and papers (cf. Annexes at the end of the present publication) which, together with the literature cited in some of them, may be considered as a basis to any student of the New Guinea flora, who desires to undertake a special investigation in this matter. As far as the facts are concerned my aims have been of a double nature; to get an impression of the principal associations of the island, and to arrange some floristic data in such a way, that they may become comparable to those of the surrounding islands and continents.

    Description: Anl\xc3\xa4sslich der Centenarsfeier des \xe2\x80\x9eRijksherbarium\xe2\x80\x9d zu Leiden im Jahre 1930 schrieb Prof. Dr L. DIELS in Berlin-Dahlem einen Beitrag, betitelt \xe2\x80\x9eHerbarien und Sammler\xe2\x80\x9d, f\xc3\xbcr die \xe2\x80\x9eHerdenkingsuitgave\xe2\x80\x9d der \xe2\x80\x9eMededeelingen van \xe2\x80\x99s Rijks Herbarium\xe2\x80\x9d (No. 62\xe2\x80\x9469, Leiden, 1931). In diesem Beitrag wurde Wert und Bestimmung von Herbarien und die Aufgabe des Sammlers gekennzeichnet. Durch das Sammeln ganzer Pflanzen und genauer Etikettierung k\xc3\xb6nnen, so f\xc3\xbchrte DIELS aus, die Sammler viel beitragen zur Vermehrung der botanischen Kenntnis, u. a. von den Verbreitungsgebieten der Pflanzen und der Pflanzen\xc3\xb6kologie. DIELS kommt zu dem Schluss: \xe2\x80\x9eSelbst in den alten Kulturl\xc3\xa4ndern liegen dankbare Aufgaben in dieser Richtung vor. Doch am gr\xc3\xb6ssten ist die Verantwortung der Anstalten, die ihre Arbeit in erster Linie auf die tropischen Floren wenden. Denn das Gesamtbild, das wir uns von der Pflanzenwelt machen, gewinnt seinen Umfang, seine Mannigfaltigkeit und viele besondere Farben aus den Floren der Tropen. Mit der fortschreitenden Vernichtung der urspr\xc3\xbcnglichen Zust\xc3\xa4nde in den, w\xc3\xa4rmeren L\xc3\xa4ndern droht dieses Bild zu verarmen und eint\xc3\xb6niger zu werden, ehe wir noch wirklich seinen Reichtum begriffen haben\xe2\x80\x9d.\nJava, das heutigentags gr\xc3\xb6sstenteils Kulturland geworden ist, best\xc3\xa4tigt die Wahrheit des zitierten Satzes \xc3\xbcberdeutlich. So sind, um ein spezielles Beispiel herauszugreifen, die Urw\xc3\xa4lder der Niederung, welche fr\xc3\xbcher grosse Fl\xc3\xa4chen bedeckten, bis auf kleine Resten Opfer der Kultivierung geworden, lange bevor man die urspr\xc3\xbcngliche Vegetation in ihren Elementen gut kennen gelernt hatte. M\xc3\xb6ge die Entdeckung von Relikten heute auch interessant sein, vom pflanzengeographischen Standpunkt aus muss man sehr bedauern, dass die systematische Erforschung der Vegetation nicht vor der Vernichtung des Urzustandes zu gewisser Vollendung gebracht werden konnte.

    Contributions to Indo-Australian Herpetology (1934)
    In:  Zoologische Mededelingen vol. 17 no. 9, pp. 161-251
    Details
    Publication Date: 2024-01-12
    Description: A complete account of all the reptiles then known to occur in the Indo-Australian Archipelago was published by De Rooij in 1915 and 1917.\nSince this time several new species have been described, while others have been suppressed or revived. Also the problem of geographical variation begins to penetrate in herpetology more and more. While studying the herpetological collections of the Rijksmuseum van Natuurlijke Historie, Leiden and the Zoological Museum, Amsterdam, it became clear to me that, though De Rooij\'s books offer a sound basis for further studies on the reptiles of the Indo-Australian Archipelago, a great deal of revisional work must still be done before our knowledge of the herpetological fauna of that region will be fairly complete. As I can devote only a rather small part of my time to this revisional work, I am not yet able to publish a complete revision of whole families or genera, but in the present paper I have brought together revisional notes on a number of species, as well as notes on distribution.\nThrough the kindness of Dr. L. Stejneger and Miss D. M. Cochran, United States National Museum, Washington, I was supplied with a list of the reptilesl) collected by Dr. Abbott and Dr. Boden Kloss on the islands west of Sumatra. As the fauna of this part of the Archipelago is still very insufficiently known, I have included notes on this collection, part of which I received for personal examination. I wish to express my thanks to Dr. Stejneger and Miss Cochran for their permission to make use of the unpublished locality-records in their list.\nMy heartiest thanks are due to the following persons for the specimens sent to me for personal examination and for the valuable information

    Ueber eine Anomalie von Acromitus flagellatus (Stiasny) (1934)
    In:  Zoologische Mededelingen vol. 17 no. 2, pp. 8-10

    Publication Date: 2024-01-12
    Description: Bei erneuter Durchsicht des reichhaltigen Materiales von Acromitus flagellatus (Stiasny) in der Scyphomedusen-Sammlung des Rijksmuseum van Natuurlijke Historie in Leiden (vergl. meine Mitteilungen daruber, 1920, Uebersichtstabelle III und 1921, p. 131/136) fand ich ein Exemplar, das eine bemerkenswerte Anomalie in der Ausbildung des Gef\xc3\xa4ssystems des Schirmes aufweist. Da Anomalien bei dem Genus Acromitus ziemlich selten sind, habe ich schon bei fr\xc3\xbcherer Gelegenheit einige interessante F\xc3\xa4lle beschrieben (1922, Fig. 11, p. 547 und 1929, Fig. 14 u. 15, p. 212/213).\nLight (1914) erw\xc3\xa4hnt solche nur ganz beil\xc3\xa4ufig in seiner Beschreibung von Acromitus maculatus (p. 215). \xe2\x80\x94 Das vorliegende Exemplar, Inv. N\xc2\xb0. 127b, P. Buitendijk, Reede van Batavia, 1907, ist in mehrfacher Hinsicht erw\xc3\xa4hnenswert. Die vortrefflich erhaltene Meduse ist 52 mm breit und 21 mm hoch; ist also von mittlerer Gr\xc3\xb6sse. Gonaden ganz schwach entwickelt. Armscheibe, Mundarme ganz normal. Am Schirmrande finden wir 8 Rhopalien. In einem Sektor liegen 2 Rhopalien nahe nebeneinander, nur getrennt durch 4 Velarl\xc3\xa4ppchen an Stelle der normalen 8. Zwei benachbarte Sektoren sind etwas breiter am Schirmrand als die \xc3\xbcbrigen normal ausgebildeten, ohne dass es jedoch zu einer Vermehrung der Zahl der Randl\xc3\xa4ppchen gekommen w\xc3\xa4re. Der Ringcanal ist in seinem ganzen Verlaufe ungew\xc3\xb6hnlich breit und kr\xc3\xa4ftig entwickelt. Es sind 8 Rhopalarcanale und nur 7 Interrhopalar (Adradial-)Canale vorhanden. Der (im Sektor links in der Textfigur) sonst stets zwischen 2 Rhopalarcanalen liegende Adradialcanal ist ausgefallen. Das intracirculare Anastomosennetz zeigt in den meisten Sektoren das normale Verhalten: das zierliche Baumchen mit dem Rhopalarcanal als Trager des Netzwerkes (Sektor
