| The post-Glacial history of the forests in the Netherlands has been reconstructed fairly well by pollen analysis of several bogs. At the same time stratigraphical investigations shed some light on the way in which these bogs had been built up, i.e. on the plants by which, in the various forest periods, peat was formed. Though these data are quite interesting, they do not give a good impression of the entire synchronal herbaceous flora, as they are limited to the peatbuilding plants. As yet very little is known of the rest of the vegetation (water-, marsh- and land-plants) of the late-Pleistocene and Holocene periods. We must look for their remains in other deposits, particularly in clay and sand, wherein however few land plants will be found, as their... |

| The name Pleiocarpidia was coined by K. SCHUMANN (ENGLER und PRANTL, Natürliche Pflanzenfamilien, Nachträge I, p. 314, 1897) for a genus described in 1873 by HOOKER f. (BENTHAM et HOOKER, Genera Plantarum II (1), p. 71) as Aulacodiscus: HOOKER’S genus had to be rebaptized, because the name Aulacodiscus had been used already in 1844 by EHRENBERG for a genus belonging to the Diatomeae. A proposal made by O. KUNTZE(POST et KUNTZE, Lexicon, 1904) to change the spelling of the name introduced by SCHUMANN in Pliocarpidia can not be accepted, as there is no rule prescribing the transcription of the Greek diphthong in the manner advocated by the proposer. The plant on which HOOKER’S genus was founded, a small tree not uncommon in the Malay Peninsula, had been... |

| INTRODUCTION Engaged in the study of fossil shells belonging to Thiele's sectio Cerithideopsilla of the genus Cerithidea Swainson and deriving from plio-pleistocene beds in East Java, I failed to find a satisfying account on the recent species of this group. Therefore I resolved to examine as large a material as possible myself in order to settle the value of the different species and varieties that have been described in literature. This investigation led me to the conclusion that even after the inspection of some 1950 specimens I cannot speak the final word, as ecological observations seem necessary to test the taxonomic value of the characters used for distinction. But a preliminary order may be established by the following revision of the material... |

| This annotated list of the mammals, lizards and mollusks of the Leeward Group, is based on author’s collection and therefore includes additional mainland-records of the island-species. As a rule a short commentary is given only as a guide to the adopted nomenclature and classification, in case of controversial data which are not yet settled, if important for our knowledge of regional distribution, mentioning vernacular names. Regarding the mammals, all known material-records are included. |

| Dr. C. A. BACKER and Dr. O. POSTHUMUS, Varenflora voor Java. Overzicht deiop Java voorkomende varens en varenachtigen, hare verspreiding, oekologie en toepassingen. Uitgave van (Fern flora for Java. Conspectus of the ferns and fern allies occurring in Java, their distribution, ecology and use. Issued by) ’s Lands Plantentuin, Buitenzorg, June 1939. I—XLVII, 1—370, 1 Plate, 1 map and 81 text figures. — ƒ 7.50. The users both at home and abroad of Dr. BACKER’s florae have always regretted that, however carefully these books have been prepared, most of them were imperfect in one way or another. They were either restricted to certain vegetations (weedflorae for tea and sugar-cane) or did not cover all groups of vascular plants; the ”Flora van Batavia“ (1907),... |

| I propose in this part of my catalogue of the Solariidae to deal only with the genus Solarium s.s. and to reserve the remaining genera of this family for the next publication. For the division of the Solariidae in genera I followed Thiele's Handbuch der systematischen Weichtierkunde, also as far as concerns the names. Not only did I mention those species of which we possess specimens in the Leiden Museum, but, like in the former catalogues, I have included also, as far as possible, those species of which no material is present in our collections. The list is composed on the same lines as my previous ones. Of all species of which we possess material a list is given of the specimens, stating: 1) the letter which indicates specimens from the same locality and... |

| Whilst studying the material of the genus Securidaca for the “Flora of Suriname”, I found it in most cases extremely difficult or even impossible to identify the species. The original descriptions are, as a rule, very short, and they have been based for a good deal on incomplete material: mature fruits, for instance, are often missing. Hence it is not surprising that on quite a number of species the opinions of taxonomists disagree. Accordingly on the one hand we may find in the various collections the most different species lumped together under the same name, while on the other hand one and the same species may appear under several names. A study of the type specimens therefore, was obviously very desirable. I am indebted to the “VAN EEDEN FONDS” for... |

| This paper contains the results of the study of the fish-collection, made by P. Wagenaar Hummelinck, on the islands of the Leeward Group and some parts of the adjacent South-American continent, in 1936—’37 and in 1930. The latter have already been studied by Miss M. Sanders (1936) and are only included for completeness’ sake. The material has been presented to the Zoological Museum of Amsterdam. |

| The region which forms the field of these studies lies between Trinidad and the Goajira-peninsula, off the northcoast of South America, comprising of seventeen islands or island-groups with a total area of about 2000 square kilometers. It is a part of the Venezuelan Republic, excepting Curaçao, Aruba and Bonaire, which is Netherlands territory. The total number of inhabitants can be estimated at 164000, chiefly confined to Margarita (70000), Curaçao (61000), Aruba (24000), Bonaire (5500) and Coche (3000). This region was visited in 1936 and 1937 with the main object of studying the land and freshwaterfauna, excluding birds and the greater part of the insects. For comparison some parts of the adjacent continent were also visited. |

| INTRODUCTION The coral reefs of the Togian islands grow up as steep barrier reefs and atolls. Moreover small fringing reefs occur along the islands. The geological structure of the islands, as well as the history and morphology of the reefs are treated in a separate paper 1). I will here mention only one of the striking features of the reefs. The reefs are situated in a zone, famous for the unruffled calm and undisturbed quiet of the sea, because they are protected from the influence of both monsoons. In a curve from West to North they are sheltered against the North monsoon by the Northern arm of Celebes; on the South of this group the Eastern arm of Celebes breaks the influence of the South East monsoon, which, blowing across the Banda Sea is only... |

| Whilst visiting the Leeward Group, little time could be spared to the collecting of mammals; from Odocoileus and Sylvilagus however, a rather representative series could be obtained. Regarding this, I must offer my grateful thanks and appreciation to the people who so ably and kindly assisted in securing the specimens. I am especially obliged to Mr. van der Linde Schotborgh for presenting me with a living Curaçoan deer and to Mr. de Wit for organizing our three shooting-parties, ending with the aquisition of the type of Odocoileus gymnotis curassavicus. Señorita Fanny Maneyro made me a present of a two days old fawn, on the occasion of a short visit to her uncles estate on the Peninsula de Araya. Little “Chacopato” was bottle-fed in my room in Porlamar,... |

| Among the indeterminate Loranthaceae of the Kew Herbarium, I found two specimens, belonging to different species, both collected by the Reverend R. B. COMINS in San Cristoval Island. One of them appeared to represent a new species, the other to belong to a species formerly described by me, and to give a welcome completion to the knowledge of this species. |
