Description de copépodes nouveaux du plankton marin de Nha-trang (Viêt-Nam)

The author had the opportunity to study a large collection of plankton tubes or pelagic marine copepods, collected in the Nha Trang region (Vietnam-South). Many of these individuals belong to the group Monstrillides.

Description de Copépodes nouveaux du plankton marin de Nha-trang (Viêt-Nam) (suite)

The author gives a detailed diagnosis and complete iconography of three females of Mazellina bulbifera nov. spec.

Pyramidellidae de Pho-Hai (sud Viêt-Nam)

After having pointed out their distribution into several subfamilies, genera, and sub-genera of Pyramidellidae, this note describes 44 species of this family. Forty-two were collected by the author in the beach sands at Pho-Hai, near Phan-Thiet (South-Vietnam) and two were dredged off Phan-Thiet by the Nha-Trang Oceanographic Institute. Among these species twenty-one are new: Cossmannica champaensis, Odostomia (Odostomia) chamorum, O. (Megastomia) elata, O. (Megastomia) binhdinhensis, 0. (Megastomia) gestroides, O. (Jodanula) megembryon, Pyrgulina (Standeniella) difficilis, P. (Parthenina) monicae, P. (Pyrgulina) phohaiensis, Chrysallida phanthietina, Egilina gigantea, E. babellina, E. (Numaegilina) ventricosa, Babella cylindrica, B. crassicostata, Miralda franciscae, Turbonilla barthelemyi, T. (Asmunda) secta, Pyrgiscus infantilis, Careliopsis sublaevis, Cingulina inaequalis.

Observations sur les premiers pléopodes males d'espèces d'Actea (Brachyures) du Viêt-Nam

Few observations on the first male Pleopode of the genus Actea are available. Examining the possibility of using their characteristics for a taxonomic work, the authors expose the obtained data on the subject and describe the Pleopods of 18 species of Actea collected on the Viet-Nam seashores. A tentative to define the different types of Pleopods gives a new argument to consider and recognize the genus Banareia as a distinct genus of Actea.

Les espèces de Carpilodes (Brachyura-Xanthidae) du Viêt-Nam

The authors have identified 18 species of the genus Carpilodes, collected on the Viet-Nam sea shores; three species and one variety are new. A key for the identification of the thirty species and two varieties of the genus is associated with the description of the new forms. The pleopods 1 of the male for the great part of the species identified in Viet-Nam sea shores are figured.

La végétation des places vaso-sablonneuses de la presqu'île de Cam-Ranh. Note n° IV: Introduction à l'étude des sables littoraux du Centre Viêt-Nam.

The important sedimentation of the Bay of Cam-Ranh rivers Suȏi Hai, Truong Suȏi, Suȏi Ca, Suȏi Tra Duc, Sȏng Can, Sȏng Trau from the Annamite Chain, provides hydrophilic vegetation (mangroves and swampy meadows) with a favorable habitat.

La carte de la végétation de la presqu'île de Cam Ranh (Région de Nha Trang). Note n° V: Introduction à l'étude de la végétation des sables littoraux du Sud Viêt-Nam

The 1:50000 Vegetation Map of Cam Ranh Peninsula is one of the first study performed in South Vietnam; it aims to locate various vegetation on coastal sands and it represents a synthesis of phytogeographic observations. (Barry J.P. and Phung Trung Ngan, 1960, Barry J. P., Le-Cȏng-Kiet Hoang and Pham-Hȏ, 1961 Barry J. P., Le-Cȏng-Kiet and Vu-Van Cuong, 1961).

Introduction à l'étude de la végétation des sables littoraux du Sud Viêt-Nam. Note no. III: Les associations végétales de la presqu'île de Cam-Ranh (Région de Nha-Trang)

The natural vegetation on the coastal sands of Central and Southern Vietnam seems to not be in relation with the chemical composition of the sands, but with the age of sediments.

Les poissons d'importance commerciale au Viêt-Nam

The fishery products represent one of the most important resources in Vietnam. The paper focuses on distribution, fishing gears, fishing seasons and current use of commercial fish species.

Une estimation de l'épaisseur de la croute terrestre au-dessous de la Mer de Chine

Study on the dispersion of Rayleigh waves across the China Sea in 1964 has given following conclusions: - Thickness of the crust below the Sea could be varied from 12 to 15 km according to the area. -There would be a slight diminution of the thickness when the Sea depth becomes deeper. - Central part of the Sea very probably belongs to the regional character no. 3 of Santo. The present work is known as the first which estimates particularly the thickness of the crust below the China Sea.

Quelques notes sur le plancton marin recueilli en 1953, par M. G. Ranson, dans la baie de Nhatrang-Cauda (Viet Nam)

Mr. G. Ranson found a small collection of plankton in Nha Trang (Vietnam), during a mission in the Far East. The samples were harvested in the Bay of Cauda at a water depth of 15-20 m. The author examined a number of samples kept in formalin, extremely rich in diatoms and in good condition. The group of pelagic copepods has been the most carefully studied.

Chétognathes recueillis dans la Baie de Nhatrang-Cauda (Viet-Nam)

The author presents his systematic study on a collection of 58 coral tubes containing samples of Chétognathes.

Le Copépodes pélagiques de la Baie de Cauda (Viet-Nam)

The author presents his study on marine pelagic fishes collected on the coast of Annam, in the Bay of Cauda, where the Indochina government built the Institute of Oceanography. These samples allowed the systematic identification of pelagic Copepods.
