The Gulf of Capbreton is one of the first submarine canyons known in the world's oceans. A specimen sheet, based on soundings, was made by the Scientific and Technical Institute of Marine Fisheries. Moreover, west of the entrance of the English Channel, the studies conducted by E. Le Danois and L. Beaugé (1), who drew a map limited to the east by the shoal of la Chapelle, highlighted the complexity of the topography of the continental shelf at the two extremities of the great arc formed by this slope in the Bay of Biscay. |

Audouin, Jacques. |
The study of the fauna and flora in a pond requires a good knowledge of this environment's physico-chemical conditions. Gourret (1897), Pavillard (1905), Sudry (1911), then more recently Mathias and Tcherniakofsky (1932), Fatemi (1938), Tuzet (1947) and J. Escot-Molinie (1955) provided information on the temperature, salinity, density, PH, etc. of one of the largest ponds of the lower Languedoc, that of Thau. However, for a century, the water exchange between the pond and the Mediterranean Sea has often differed. These changes (the most recent ones being among the most interesting) have modified its hydrology. This is one of the main reasons which lead us to carry out this study. This study which started at the end of winter 1954-1955 is still in process,... |

Boschma, H.. |
In the collections brought together by Dr. L. B. Holthuis during a visit to Australia there is a specimen of the crab Pilumnopeus serratifrons (Kinahan) bearing the Rhizocephalan parasite Loxothylacus spinulosus Boschma. The locality of the type specimen of this parasite was mentioned as "Pacific Ocean" (Boschma, 1928, p. 172) ; in all probability it was collected in the region of the East coast of Australia, because the crab Pilumnopeus serratifrons is known from this region only. The new record gives occasion to restrict the type locality of Loxothylacus spinulosus to Mosman, Sydney, New South Wales. Examination of the specimen showed that it corresponds in all essential characters with the type specimen, while a parasite of the crab Glabropilumnus... |

Bruggen, A.C. van. |
From August 16 till September 1, 1955, Dr. H. C. Blöte, Mr. J. J. Barkman, and the present author were the leaders of an excursion of students in biology of the University at Leiden to Central France. For some two weeks the party was hospitably lodged in the "Station Biologique" in the village Besse-en-Chandesse (département Puy de Dôme), 30 km S.S.W. of Clermont-Ferrand. Thanks to the generosity of Prof. R. Hovasse and Dr. L. Olivier, we could stay in this biological institute, which belongs to the University at Clermont-Ferrand. During the excursion the author paid special attention to the collecting of land and freshwater Mollusca. The very dry and hot weather during our stay was one of the main difficulties in carrying the project into execution;... |

Laidlaw, F.F.. |
I am indebted to the authorities of the Leiden Museum for the opportunity of examining and reporting on the large collection made by the late Dr. E. Jacobson on Simalur island and on its smaller satellite Pulau Babi, in 1913, between the months of January and September. The collection is large enough to enable one to study good series of a number of the forms collected, and to justify the naming of several new races. Some new forms had already been named by Dr. C. A. van der Willigen, who studied the collection several years ago. Whenever possible I adopted Dr. van der Willigen's MS names. It is now possible to compare the faunas of Simalur Is., Nias Is., and Enggano Is., but the fauna of the Mentawi islands is unfortunately still very imperfectly known. I... |

The present paper deals with part of a recently acquired collection of freshwater fishes, captured by Mr. J. VAN DER KAMP, Amsterdam, during his military service in Surinam in the years 1956 and 1957. All material is finely preserved and ecological data as well as numerous black and colour photographs by the collector add to the scientific interest of the collection. |

The zoological collections made by the 1948—1949 Surinam Expedition contain about 200 mammals, brought together by the zoologists Dr. D. C. GEIJSKES and Mr. P. H. CREUTZBERG. Though the collection consists mainly of species which had already been reported from Dutch Guiana, it is of considerable value, in the first place on account of the detailed data concerning the localities, biotopes, and biology, and secondly because not only the skins and skulls of the collected specimens have been preserved but as a rule also their complete skeletons. The present paper ¹) deals with the Primates; the other groups of mammals will be treated in subsequent publications. Thanks are due to Dr. D. C. GEIJSKES, who is responsible for the notes on the biology of the... |

Au cours de la dernière trentaine d'années, la collection de Mantides du Rijksmuseum van Natuurlijke Historie à Leyde a été augmentée peu à peu par des exemplaires récoltés à des localités différentes. Récemment une partie de ce matériel a été récoltée pendant l'expédition de la Société Royale Néerlandaise de Géographie (Koninklijk Nederlandsch Aardrijkskundig Genootschap) en 1939 et pendant les voyages à la Nouvelle Guinée du Dr. L. D. Brongersma et ses collaborateurs en 1952 jusqu'à 1955 1). Les exemplaires jusqu'ici pas identifiés étaient devenus si nombreux qu'on pouvait attendre de résultats importants d'une étude de ce matériel. Aux pages suivantes on trouvera de résultats premièrement concernant un nombre d'espèces du genre Hierodula, pour la plus... |

Blöte, H.C.. |
Notre connaissance du groupe des Orgeriini est d'origine récente. La première espèce qu'on a fait la description est Bursinia hemiptera, qui provient d'Italie et qui est décrit comme Fulgora par O. G. Costa en 1840. En 1849 L. Dufour a décrit Dyctiophora longipes et D. genei, étant des espèces qu'on a transféré aux genres Almana Stål et Bursinia Costa. Ce n'était qu'en 1859 que C. Stål décrit Orgerius rhyparus selon des exemplaires provenant de Californie. F. X. Fieber publia en 1866 les espèces paléarctiques Ranissus leptopus de Turquie, R. discrepans, R. acucephalus et R. platypus de Grèce; il transféra lui-même les espèces citées au genre Orgerius Stål en 1872. Passant outre au tableau analytique des formes européennes de Fieber (1875-1876) et aux... |

Les insectes faisant l'objet de ce mémoire font partie des collections du Musée de Leiden et m'ont été communiqués par Monsieur le Docteur Blöte. Je tiens à lui exprimer ici ma plus vive reconnaissance. En plus des 16 espèces nouvelles dont suivent les descriptions j'ai pu relever dans le matériel confié huit autres espèces inédites du genre Exocentrus Muls. Les descriptions de ces huit espèces seront publiées par moi ultérieurement au cours d'une révision complète du genre Exocentrus Muls. 1. Myagrus javanicus, n. sp. Allongé. Antennes deux fois et demie plus longues que le corps ( ♂ ) ou presque deux fois plus longues ( ♀ ); le troisième article de la longueur du quatrième, de moitié plus long que le scape. Lobes inférieurs des yeux beaucoup plus hauts... |

Ensaios foram realizados para estudar o comportamento de 25 leveduras na fermentação vinária, com o objetivo de selecionar aquelas que pudessem influir na obtenção de vinhos com grau alcoólico satisfatório e teores de ácidos voláteis e aldeído acético baixos. Os resultados obtidos mostraram que as leveduras n. 13, 14, 16, 25, 20, 15, 4, 3, 2 e 17 atingiram essa finalidade, podendo servir como ponto de partida para novas observações nas cantinas industriais |

Na composição de fórmulas de adubação para a cultura da batatinha com freqüência entrava o farelo de torta de algodão, com resultados satisfatórios (1). Em conseqüência da proibição do seu emprêgo como fertilizante, para ser usado exclusivamente na composição de rações para animais, procurou-se um outro farelo que pudesse substituí-lo e que não tivesse emprêgo "in natura", na alimentação animal. Dentre eles sobressaiu-se o farelo de torta de mamona, que possui um princípio tóxico, a ricinina. No presente trabalho são fornecidos os resultados da sua utilização na composição de fórmulas de adubação para batatinha. As conclusões a que se chegou vieram recomendar o seu uso em confronto com o farelo de torta de algodão e sulfato de amónio. Os resultados... |

A conservação de tubérculos de batatinha para o consumo vem preocupando os pesquisadores em diferentes países, por se tratar de um produto fácilmente perecível. Além dos trabalhos sôbre frigorificação, já bem conhecidos, iniciou-se o emprêgo de substâncias químicas inibidoras da brotação e que impedem as podridões causadas por Fusarium. Dentre essas drogas sobressairam-se o éster metílico do ácido alfanaftaleno acético e o tetracloronitrobenzeno. Os resultados alcançados, embora contraditórios em alguns pontos, vieram demonstrar a viabilidade do seu uso, principalmente em países onde o inverno é rigoroso. Das experiências e observações feitas no Instituto Agronômico de Campinas a partir de 1946, chegou-se à conclusão que as referidas drogas somente... |

An inventarisation of the plankton living in an old branch cut off from the river Waal has been made on August 16, 19 and 23, 1955. In the deep part lake plankton (Limnoplankton) was found, and in the shallow parts pond plankton (Heleoplankton) occurs. Some rare plankters typical for oligotrophic waters were found in a certain part of the river branch. A chemical analysis of this part of the water shows no real difference with other parts. The part of the old branch connected with the river Waal has a plankton community of its own. This is caused by the polluted river water. The horizontal distribution of plankton on August 16, 1955, was investigated. The vertical distribution of plankton investigated on August 28, 1941, is also given. |

1. The Svinö bank, mostly made up of a shelf limited by the isobath 200 m, is located along the Norwegian coast, off the Stat cape and the Romsdael islands, between L. N. 62° and 63°15' approximately. It is limited to the north-west by some steep slopes, to the west by muddy bottoms with a gentler slope.2. The hydrological regime is mostly characterized by the contrast between costal waters, with a low salinity, and offshore waters, around the slopes of the bank, coming from the Atlantic Ocean. The Boreal regime (waters at 6~7°C,) observed all year long throughout the whole bank contrasts with the Arctic regime (water temperature lower than O°C) observed at depths lower than 600-800 m. An overall current directed to the northeast seems to run from the... |
