| The Dalskog Dais-Rostock area lies in the Swedish province of Dalsland, to the west of lake Vänern. It lies entirely within the Upperud sheet of both the topographic (1926) and geological map (1870) and comprises parts of the parishes Gunnarsnäs, Dalskog and Ör. As shown by the outline map (fig. 1), the investigated region is situated in an area of gneiss-granites and supracrustal formations, which lies to the west of lake Vänern as an island in the great, highly metamorphic complex of gneisses of southwestern Sweden. In the adjoining table the geological events wich left their marks in the rocks of the Dalskog Dals-Rostock area are listed in chronological order. For the sake of clearness the table has been completed with data known from the adjoining... |

| In deze publicatie is een deel der Amerikaanse Podostemaceae van de onderfamilie Podostemoideae opgenomen nl. de nauw verwante geslachten Apinagia, Marathrum, Rhyncholacis, Wettsteiniola, Lophogyne, Monostylis, Jenmaniella en het nieuwe geslacht Macarenia. Nagegaan wordt waarom deze geslachten verwant zijn. Uit het onderzoek is gebleken dat de geslachten Apinagia en Oenone, zoals die beschreven werden door Tulasne in 1852, niet als twee afzonderlijke geslachten gehandhaafd kunnen blijven. De indeling van de onderfamilie Podostemoideae, zoals Engler die in 1930 gaf, is gewijzigd in die zin dat de subtribus Mourerinae tot tribus is verheven en de subtribus Apinagiinae en Marathrinae met de tribus Eupodostemeae tot één tribus Eupodostemeae verenigd zijn. In... |

| Dr Junge of the „Rijksmuseum van Natuurlijke Historie te Leiden” has been so kind to lend me the following specimens of bats, registered as Tylonycteris pachypus (Temminck) (all in alcohol). reg. no. 273 ...... 3 males, 3 females ......... Java. „ „ 274 ...... 2 females (1, m) ............ Cambodge. „ „ 280 ...... 4 spec ........................ Annam. „ „ 1260 ...... 1 male, 1 female ............ Mt. Dapad, Borneo. „ „ 1420 ...... 4 spec. (v, w, x, y) ......... Buitenzorg, Java. „ „ 1645 ...... 34 spec. ........................ Malang, Oost-Java. When examining this material, I discovered that the 2 female specimens I and m of Cambodge (reg. no. 274), were misnamed. The label is reading: |

| The increased importance which the European red mite (Paratetranychus pilosus (Can. et Fanz.)) (= Metatetranychus ulmi (Koch)) has assumed in recent years has led to an intensive study of its biology and natural history. In the course of these investigations many workers, and in particular those in Nova Scotia (vide Lord, 1949), have become convinced that this pest can be controlled, on apple trees at least, by natural means and that some of the most active agents in its eradication are the representatives of that group of predaceous mites which Vitzthum (1941) placed in the subfamily Phytoseiinae Ber'lese, 1916 1). As the late Dr. A. C. Oudemans of Arnhem included many if not most of these species in the genus Typhlodromus as he conceived it, this paper... |

| A short account of the establishment of the Herbarium of the Department of Forests, Papua and New Guinea appeared on p. 61, no 3, volume I of Flora Malesiana Bulletin. This Herbarium has now been firmly established and is constantly receiving collections of plants from various parts of Papua and New Guinea. As a routine measure these are being distributed to the following herbaria: The Queensland State Herbarium at Brisbane, Queensland; The Herbarium of the Division of Plant Industry, Commonwealth Scientific and Industrial Research Organisation, Canberra; The Arnold Arboretum, America; The Herbarium at Kew, England; The Herbarium at Leiden, Holland; The Herbarium at Bogor, Indonesia; The Herbarium at Singapore, Malay States; The Herbarium of the Imperial... |

| A l’E d’Orange-Avignon, au pied du Mt. Ventoux, s’élève un petit massif, qui est limité au N et à l’W par l’Ouvèze (fig. 1), à l'E par la route de Vaison—Malaucène—le Barroux et au S par la route du Barroux à Vacqueras. Dans la littérature géologique ce massif se trouve le plus souvent indiqué sous le nom de massif de Gigondas, d’après le village situé sur le versant occidental du massif. |

| In literature only very scanty information is to be found about the viscera of the Boid genera Tropidophis and Trachyboa, and therefore I believed it worth while to publish some notes which I made during dissections of the following species and subspecies: Tropidophis melanurus (Schleg.), Tropidophis maculatus haetianus (Cope), Tropidophis pardalis pardalis (Gundl.) and Trachyboa gularis Ptrs. The notes are in no way exhaustive; the specimens have been preserved in alcohol for a long time, and therefore it was not possible to study all features in detail. All but two genera of the Boidae have two well developed lungs. One of these two exceptions was mentioned already by Cope (1894, pp. 218, 220: Ungualia; 1900, p. 697), viz., the genus Ungalia (i.e.,... |

| Compared with their New World relatives of the subfamily Cyprinodontinae, the Old World Cyprinodonts are but little known. However, some interesting accounts on Turkish species, discovered by Kosswig, Sözer and Aksiray, have recently been published. Besides the species known, several new forms and species are described. While compiling an account on these fishes suitable for the home aquarium (Hoedeman & Bronner, 1950—1951), we felt some characters need reexamination, not only of Aphanius, but also of the North African genus Tellia which is said to differ from Aphanius only in the absence of ventral fins. |

| Sous le nom de Cynoglossus xiphoideus Günther, la collection ichthyologique du Zoölogisch Museum, Amsterdam possède 2 spécimens dont l’un est originaire de Shanghaï et l’autre, de la mer de Timor. Le spécimen de Shanghaï a été cédé au Zoölogisch Museum (sans doute à titre d’échange) par le British Museum, en 1909: c’est feu Günther qui est responsable de sa détermination. Le spécimen de la mer de Timor a été capturé par le „Siboga”: il a été mentionné par Weber (1913), puis par Weber et de Blaufort (1929). De teinte également très claire, ces deux spécimens semblent avoir subi une action décolorante. Tous deux sont des femelles; ni l’un ni l’autre n’appartiennent à l’espèce désignée par leur étiquette respective, espèce avec laquelle ils n’ont guère de... |

| Records of cave-dwelling Lepidoptera are scarce in comparison with those in other orders of Insects, e.g., Coleoptera, of which even a whole subfamily (Silphidae, Bathysciinae) is in a most remarkable way adapted to this peculiar habitat. In the group of the so-called Microlepidoptera we could find examples of some eight species only, belonging to different families. Apparently none of them is a true cave-dweller, i. e., a permanent resident of caves and really adapted to life in total darkness. Crypsithyris spelaea Meyrick, 1908 (Tinaeidae) only has been regarded as an exception. This species has been described from a large cave in Moulmein, Burma, and originally was reported as "being practically bleached or colourless", but with normally developed eyes... |

| Survey of the flora of Bikini and other atolls before the atomic-bomb tests were made. The phytoplancton is excluded from the present carefully written and extensive analysis, which is most instructive to every student of tropical coral island floras. A general introduction furnishes an excellent view on Phanerogamic vegetation and land flora, the physical conditions of the islands, and the part played by different lements in coral building. The major part of the book is occupied by descriptions of the plants collected; marine Algae, of course, predominate. Several new spp. have been described e.g. in Halimeda, Rhipilia, Caulerpa, Pocockiella, Acrochaetium, Porolithion, Botryodiplodia and Fungi, etc. Latin diagnoses of new forms and species and a... |
