| In his valuable report on the freshwater fishes of British Guiana, Eigenmann (1912, pp. 64-73) gave a list of the species, together with comparable lists on the freshwater fishes of the adjacent regions. In sharp contrast with the number of 266 species reported from the Essequibo area only, the total amount of Surinam species proved to be but 118! Although since Eigenmann compiled these lists some more species have been reported from Surinam, the general situation has remained essentially the same, clearly showing the backward state of ichthyological research in this area. A possibility to improve our knowledge of this subject came when during the last four years the Rijksmuseum van Natuurlijke Historie received several more or less extensive collections... |

| Ever since his first experience with the remarkable “Upper Oligocene” molluscan fauna of the Isle of Buton, the present writer has endeavoured to find more convincing evidence for its age. One of the most tempting problems was why this fauna showed so few relationships to other fossil faunas or to the living mollusca (See Martin, 1933, 1935; Beets, 1942, a, d). Since the only firm point emerging from a number of more or less confusing data was that the closest relationships existed with the Neogene fauna of the East Indies, the writer started extensive comparisons with a number of undescribed fossil collections from that region kept in Netherlands museums (Leyden Geological Museum, Delft Mining Institute, Utrecht Geological Institute). Meanwhile,... |

| The subject of this study are soil samples taken in the “Makkumer Waard”, a wide expanse of low-lying land, which follows the Frisian coast. Stratigraphical and palynological investigations showed that in the beginning of the Atlanticum the area lay below the level of the sea, but that gradually the influence of the sea decreased and peat formation became possible. From the transition from marine deposits to Sphagnum peat (— 4,55 m to — 3,50 m) we must conclude that there has been a temporary standstill in the transgression, or even a regression, in the middle of the Atlanticum. Towards the end of the Atlantic period a sudden marine transgression followed, which deposited a layer of sand and clay on the Sphagnum peat (— 3,50 m to — 3,30 m). Shortly before... |

| The present paper constitutes a report on the Machilidae and Lepismatidae collected by Dr. C. O. van Regteren Altena in the Canary Islands in the spring of 1947. We are much obliged to Dr. van Regteren Altena for allowing us to study these interesting specimens. The first notice on Thysanura from the Canary Islands seems to be the mentioning of Machilis maritima by Lucas (1836-44). Unfortunately it is quite impossible nowadays to identify that species as understood by Lucas. Ridley (1881) mentions three species from the Canary Islands, viz., Lepisma saccharina L., from Tenerife and Gran Canaria; Lepisma mauritanica Lucas, from Las Palmas (Gran Canaria) and Lepisma eatonii Ridley, from Tenerife. L. saccharina has apparently not been found again on the... |

| So far as we know, all Burseraccae have been described as shrubs or trees, ranging from small and slender to very lofty. Some recently discovered material, however, pointed at the possibility that scandent representatives, if perhaps not true lianes, are not entirely lacking in the family. The first specimen intimating this habit to have come to our knowledge was collected by J. & M. S. Clemens on Mt. Kinabalu in British North Borneo, with the emphatic addition “surely scandent”. This specimen is almost certainly a Dacryodes in the relationship of rugosa (Bl.) H. J. Lam, var. virgata (Bl.) H. J. Lam. It appeared to deserve specific rank and it has been described by the junior writer underneath as D. scandens. Full particulars are give there. |

| A full report on the birds collected during the expedition of the "Koninklijk Nederlandsch Aardrijkskundig Genootschap,, to the Wissel Lake district in 1939 will appear in "Nova Guinea". Publication of this report is delayed, however, and therefore short descriptions of the new subspecies, which were found during the work on this collection, are given here. Rallus pectoralis connectens nov. subspec. In the colour of the upper parts connectens agrees with alberti from SE New Guinea, it differs, however, by the paler breast and less blackish abdomen and in the larger size, especially of the bill. The difference with mayri from the Arfak Mountains is, that the upper parts in connectens are more overflown with reddish brown and that, on an average, the latter... |

| We are very sorry to learn that Mr J.M. Black, the father of South Australian botany, passed away suddenly but in full harness after a short illness in his 97th year, medio December 1951. Dr Black was born in Wigtown, Scotland, and received his early education there, finishing in Dresden, Germany. He arrived in South Australia in 1877 and farmed for 5 years. Between 1883 and 1902 he held varied and finally important positions on the staff of ”Hansard”, ”The Register”, and ”The Advertiser”. Having achieved the highest position possible in this field he retired to devote full time leisure to the study of native and naturalised plants growing in S. Australia. He achieved considerable fame for by 1929 he had completed his four part work ”Flora of South... |

| This paper is based on the material of Callichthyid catfishes (genera Hoplosternum and Callichthys) present in the collections of the Zoological Museum, Amsterdam. The study was induced by some specimens of „kwi-kwi” introduced from Paramaribo by Mr. Arn. J. d’Ailly mayor of Amsterdam. Some of the specimens are still alive in the local aquarium. Two forms may clearly be distinguished and identified as Hoplosternum littorale (Hancock, 1828), and Hoplosternum thoracatum (Valenciennes, 1840), though both are subspecifically different. |

| Since the publication of my paper on the prawns of the subfamily Palaemoninae collected by the Siboga and Snellius Expeditions (Holthuis, 1950, Siboga Exped., mon. 39a9), I had the opportunity to examine more material of this group, which enabled me to make additions and corrections to the above paper. These additions and corrections are the subject of the present paper. During a visit to the Istituto e Museo di Zoologia della Università at Turin, Italy, I examined the type material of Leander deschampsi Nobili, a species which in 1950 was placed by me among the species incertae. The examination of these types made it possible for me to fix the status of Nobili's species. The collection of the Turin Museum furthermore contained material of Macrobrachium... |

| La stratification des roches cristallines (d'âge antéstéphanien) des massifs centraux des Alpes est en général à peu près parallèle à la schistosité. Également les intrusions granitiques y sont plus ou moins concordantes. Cependant les recherches sous la direction du Professeur E. Niggli de Leiden ont démontré que le contact est du massif granitique des Sept-Laux (Massif de Belledonne s. 1.) est concordant seulement en grandes lignes avec la schistosité, tandis qu'il est parfois nettement discordant en détail (voir la publication dans un des numéros suivants de ce périodique). |

| In 1949 a trip was made to Kenya Colony, British East Africa, with the aim of collecting Phanerogamic plants and Ferns. The intention was to collect 12 sets of each number which I managed to do for about 70 %. Except for the first set which will be incorporated in the Rijksherbarium, the plants will be sold to those institutes in Europe, S. Africa and America which had subscribed in advance. It is expected, however, that a few more sets in excess of the 12 aforementioned will be available. It should be noted that these will prove rather incomplete, numbering less than 30 % of the total amount. |

| The genus Callisthene is found in the Extra Amazonian part of the Brazilian mainland, particularly in the zone of the campos and in the adjacent parts of Bolivia. The genus comprises eight species, as defined in this paper. It shows its greatest diversity on the central plateau of the Brazilian state of Minas Geraes. Most of the species are typical trees of the campos of the interior Brazilian plateau, which is characterized by a climate with a severe dry season. The genus was first described by MARTIUS in 1824. He mentioned all important characters and placed it in the Vochysiaceae, a family which had been described only four years earlier by A. DE ST. HILAIRE (1820). It was named after Callisthenes (360—327 B.C.), the Greek naturalist and historian of... |

| In Ruminantia, the roots of the incisiviform teeth in the lower jaw are only partially enclosed in the bony alveolus. Only the lingual part of the alveolus continues in oral direction, the labial part being open at the anterior side, and occupied by fibrous tissue, which is elastic and compact. One look at the skull of a cow, sheep, goat or deer will suffice to convince anybody of the correctness of this statement. Closing its mouth, the animal will press downwards the incisiviform teeth in the lower jaw with the gum pad of the upper jaw, till the lingual side of the crown of the front teeth meets the gum pad. Curiously enough, this mobility of the incisiviform teeth in Ruminantia has never been explained in any handbook on dental anatomy and, in some... |

| In addition to W.H. Brown’s works Dr Quisumbing has completed our knowledge of useful Philippine plants by the compilation of a big volume which contains a mine of information of over 1000 different species. Preceded by an introduction, the systematic sequence is adopted for families, genera and species. Each species is provided with a list of its synonyms, local names, a popular description, and a digestion of its phytochemical and medicinal literature. There is an appendix on miscellaneous economic algae, one on edible and poisonous fungi, one on Philippine plants reported to cause hayfever or asthma, some fungi causing skin disease, a list of cyanophoric plants, a bibliography of 630 articles and books, and several indices. This book is of great use to... |
