| If during one’s work one comes across certain names again and again, names of old collectors, of one’s colleagues in earlier days, who with their private museums laid the foundation of our scientific institutions, one naturally becomes keen on knowing more about them. The results of this curiosity, collected by and by in spare time and sometimes too in time stolen from other more serious occupations, are given here to the public in the hope that they may meet their interest. As to me I thought it a pleasure and certainly worth the trouble. I first collected all that I could find in a casual way and at last I hunted for them more systematically, until the time came that circumstances put an end to it. Incomplete though this list may be, I now send it to the... |

| Toen ik als praeparator aan de Musea van het Genootschap werd aangesteld en mijn intrede deed in den mooien Artistuin met zijn hoog opgaand geboomte, had ik, als niet-Amsterdammer, nooit gedacht in dien tuin, gelegen in het centrum eener groote stad, zooveel vogelsoorten in wilden staat te kunnen waarnemen. Het bleek mij al spoedig, dat niet alleen in de volières van de Diergaarde op ornithologisch gebied veel te beleven viel, maar dat ook wat daarbuiten in den vrijen staat voor een scherp toeziend oog op te merken was, niet verwaarloosd moest worden. Van dien tijd af ben ik dan ook begonnen notities te maken van alle waarnemingen, die in den loop der jaren gemaakt konden worden. In totaal heb ik van 75 soorten aanteekening gemaakt. |

| Als palacontoloog bij den Dienst van den Mijnbouw in Nederlandsen Oost-Indië verkreeg ik toestemming om in de maanden Augustus tot October 1928 op eigen gelegenheid een reis te maken naar de Togian eilanden in de Golf van Tomini, Noord-Celebes. Het Hoofd van het Departement van Marine te Batavia had mij de dankbaar aanvaarde gelegenheid opengesteld op 31 Augustus 1928 te Menado aan boord te gaan van het hydrographische opname-vaartuig der Gouvernementsmarine „Eridanus”, dat met H.M. „van Doorn” de herziening van de zeekaart der golf van Tomini ging beëindigen. De „Eridanus” stond onder commando van den luitenant ter zee 1e klasse, thans kapitein ter zee H. Spits. Ik zal nimmer de groote gastvrijheid en de voortdurende behulpzaamheid vergeten, die de Heer... |

| Die Veröffentlichung von zwei neuen Funden aus dem Zweistromlande (1, 2, 3) ist geeignet, mehr Licht auf die viel umstrittene Frage zu werfen, welcher Art die von den alten Sumerern im dritten vorchristlichen Jahrtausend als Zugtiere vor den Kriegswagen verwendeten Einhufer angehört haben. Bekanntlich stehen sich diesbezüglich mehrere Anschauungen gegenüber: die einen behaupten, diese Tiere wären Esel oder Angehörige des dort wild vorkommenden syrischen Halbesels (Equus hemionus hemippus Geoffr.), die anderen sehen in ihnen Pferde oder Maultiere, also Bastarde von Pferden, und sind geneigt, diese Darstellungen als Beweise für ein weit höheres Alter der Pferdezucht im vorderen Orient anzusehen, als man früher angenommen hatte. Ich habe kürzlich an anderer... |

| The family Tettigoniidae consists of the long-horned grasshoppers with a more or less distinct sword-shaped ovipositor and with a distinct auditory organ at the proximal part of the fore tibiae. Handlirsch unites into this family 14 subfamilies of which the Pterophyllinae only are considered here. Concerning the name Tettigoniidae the opinions were diverging, but in recent literature this name is generally used. In the 10th edition of Linné's Systema Naturae (1758) a number of species of the genus Gryllus are united into the subgenus Tettigonia. This subgenus was considered as a genus by Fabricius and it would have been logical if he had kept the Linnean name Tettigonia for it. Fabricius, however, mixed up the Linnean names and called the here-mentioned... |

| On several occasions the author received specimens for determination under the name of Loranthaceae, which in reality appeared to be Phacellarias, usually parasitic on Loranthaceae. When trying to name these Phacellarias, he preceived how difficult it was to survey the literature of the genus. Though only eight species have been described, and the authors usually have indicated the main differences between their new species and the most closely allied previous ones, the most essential characteristics of the species, viz., the structures of the inflorescences, were never indicated, and a critical review of all the species has never been given. Therefore it appeared an attractive task to undertake such a revision, if only it were possible to examine all the... |

| Our knowledge of the Charophyta of Madagascar is mainly based on the rich and well-prepared collection made by Mr TH. B. BLOW, who visited the eastern central part of the island in the early months of 1924 ¹). The 384 dried specimens and a considerable number of portions of the plants preserved in formalin were determined by the well-known authority on the Charophyta, the late JAMES GROVES, who published the results of his work in the Journal of the Linnean Society (Botany), vol. XLVIII, 1928. This paper contains the descriptions of 5 new species and 3 new varieties of Nitella. Before this basic paper on the Charophyta of Madagascar was published, only very few publications appeared. As far as I know the first Madagascarian species to be recognized was... |

| There are several descriptions of the anatomy of Orthragoriscus mola L., but no authors except Van Dobben (1935) have given a functional treatise concerning the mechanism of the jaw. Unfortunately the fish described by Van Dobben seems to have been abnormal. The description which follows is based on anatomical study of two sunfishes which stranded on the Dutch coast and were placed at our disposal by the Rijksmuseum van Natuurlijke Historie, Leiden. Specimen A, a female, stranded December 10, 1935 near Burgh, in the neighbourhood of Haamstede, on the Isle of Schouwen. It has been used for a cast in the Leiden Museum and was dissected by Dr N. Tinbergen and J. J. ter Pelkwijk December 13 and 14, 1935 at the Zoological Laboratory at Leiden. Specimen B, a... |

| Some time ago I described in Blumea (5) a plant collection in book-form, collected by Hermann in Ceylon. This collection consists of two large volumes, each containing a number of dried specimens. Besides these two volumes, the Rijksherbarium is in the possession of a third one of the same size and with a similar binding, bearing on its back the title in golden characters on a darker ground: Herb: Viv: Promont. Bonae Spei Vol: I. When I saw the specimens of this volume for the first time, it struck me that they did not show the peculiar type of plants from the Cape region. A somewhat closer examination lead me to the supposition, that I had to do with plants from South America. I was strengthened in that opinion by the fact that many of the vernacular... |

| Bekanntlich wurde bis vor kurzem diese spezifisch holländische Krabbenart, die nach De Man 1892 ihre nächsten Verwandten in einem tropisch pazifischen Genus hat, nirgends anders in der Welt als in Holland gefunden. Erst im Jahre 1936 berichtete K. Schubert, dass Pilumnopeus unlängst auch im Kaiser Wilhelm-Kanal im Flemhuder-See gefunden wurde. Pilumnopeus lebt in den Gewässern von Nordholland, dem IJselmeer (der abgedammten Zuidersee) und der Provinz Seeland und wurde in der Waddensee (Rottum), (siehe Hoek 1885/87 S. 96), in der Provinz Friesland in der Nähe von Dokkum, (siehe Kamps und Otto 1934), und in der Provinz Groningen (Niezijl) (siehe Otto 1934) gefunden. Der Gedanke, dass diese merkwürdige Krabbenart durch die Versüssung des IJselmeeres daselbst... |

| Among the most remarkable finds made by Dr. van Steenis in the higher parts of the mountains of North Sumatra are a number of cushion plants. Two of these he recognized as Rubiaceae nearly related to Hedyotis verticillaris W. et A., a species occurring in similar habitats in the Nilgiri Hills, India, and in Ceylon. Hesitating, however, to express a definite opinion on their taxonomic position, he sent the material to me for further investigation. As I had occupied myself already for some time with the genus Hedyotis L. and its allies, this investigation offered me a Wellcome opportunity to test some of the principles which I had laid down for the subdivision of this group. Apart from the characters of the fruit I lay stress on the position of the... |

| The Sapotaceae have of old a bad reputation among classificators because of the extreme complexity in which the single features are distributed over its genera, species and individuals. It is, in particular, extremely difficult to find satisfactory generic delimitations and consequently, the family yields a rich field both for lumpers and for splitters. Both categories, and several intermediaries, have given their opinions, as has been recently recalled by Charles Baehni in his “Mémoires sur les Sapotacées I, Système de Classification” (Candollea VII, 1938, 394—508). It is my present purpose to deliver a few annotations with regard to this valuable publication, meant, not in the first place as criticism, but as contributions towards the extensive material... |

| This is the second contribution to a series of papers dealing with the Convolvulaceae of Malaysia (Malay Peninsula and Archipelago, Philippine Islands and New Guinea). The genera worked out here belong to the tribe Convolvuleae; they are numbered VIII—XV. Genus VII, Erycibe, belonging to the Erycibeae shall be treated afterwards in a special monograph. With regard to the geographic arrangement of the specimens mentioned, some alterations had to be introduced due to the new limitation of the residencies in the island of Java. The names and limits of these residencies are now brought into line with the data of the ”Atlas van Tropisch Nederland“ ²). |

| The present paper has been written in connection with the account of the Papilionaceae for Pulle’s Flora of Suriname. The investigations were chiefly carried on in the herbarium of Utrecht; I also spent some time in the herbaria of Kew, Leiden and Paris and of the British Museum of Natural History in London. I wish to tender my best thanks to the directors and staffs of these institutions for their hospitality and assistance and also to the „Miquelfonds” which enabled me to go to London and Paris. Further I am indebted to the directors of the herbaria of Berlin-Dahlem, Brussel, Geneva and Leiden for lending specimens. Miss A. Kleinhoonte, who first was to write the account of the Papilionaceae and had already determinated a large part of the material,... |

| Obgleich es schon mehr als hundert Jahre her ist, dass zum ersten Mal nachgewiesen wurde, dass in der Steinkohle noch erkennbare Pflanzenfragmente anwesend sind, hat doch diese Tatsache bei den Botanikern nur wenig Beobachtung gefunden vom anatomischen oder floristischen Standpunkt, weil im allgemeinen angenommen wurde und wird, dass diese Pflanzenreste so fragmentarisch sind, dass für einen Botaniker nichts damit anzufangen ist. Diese Auffassung ist jedoch nicht richtig. Neben den allbekannten Pflanzenabdrücken und den Strukturzeigenden Versteinerungen verdient die Steinkohle selber ganz bestimmt auch das Interesse der Botaniker. Bei der Untersuchung der Kohle gibt es zwei Hauptrichtungen, welche nebeneinander stehen, eine, welche die Kohle als ein... |

| In 1853 BLEEKER (I, p. 489 and 490) described two species, both from the bay of Batavia, as Julis (Halichoeres) cyanopleura and Julis (Halichoeres) pyrrhogrammatoides. He pointed out that these two species are closely related, the first to Julis poecilopterus SCHL., the second to Julis pyrrhogramma SCHL., both from Japan. Lastnamed species differ from the javanese species, besides by slightly different colourmarkings, by having 14 rays in the dorsal and the anal, against 11 rays in both fins of the javanese species. BLEEKER says that but for the difference in the number of dorsal and anal rays, which is considerable, at least for this genus, he would be temped to consider the javanese species as climatic variations (“klimaatvarieteiten”) of the japanese... |

| When, during my stay in Suriname in 1933, I planned to visit the Voltzberg, Prof. Stahel, the Director of the Agriculture Experiment Station, told me that he had discovered there, in one of the fissures in the granitic dome, which forms the top of this low mountain, an unusual kind of cassave. As I had for the “Flora of Suriname” been working on the Euphorbiaceae, I was of course much interested in this plant, especially while Prof. Stahel suggested that it would be possible to cultivate it in the Agricultural Garden at Paramaribo from cuttings. When I arrived at the Voltzberg, the plant was easily found growing in a fissure between the granite plates along one of the ravines just below the dome-shaped top. The plant possessed rather long (2—3 m) stems,... |

| As far as known at present there occur in Java 4 wild species of Gynura, viz. G. aurantiaca (B1.) DC., G. carnosula Z.M., G. densiflora Miq. and G. procumbens (Lour.) Merr. A fifth species. G. pseudochina (L.) DC., is met with as a cultivated plant only, and even as such it seems to be very rare. A sixth. G. crepidioides Bth., an African plant of recent introduction, is better placed in Crassocephalum. Only one of the wild species, G. procumbens, occurs throughout the island, from sea-level up to about 2100 m. altitude. G. aurantiaca is restricted to West- and Central-Java, where it is found between 750 and 2400 m. alt.; along watercourses, however, it occasionally descends¹ as low as 350 m.; its area of distribution, extending from Mount Gědè to Mount... |
