Note préliminaire sur quatre espèces nouvelles d'Hapalocarcinidae, avec quelques remarques au sujet du Cryptochirus rugosus Edmonson

This note briefly describes four new species of Hapalocarcinidae: Cryptochirus tri, Troglocarcinus edmonsoni, Troglocarcinus sheni, Troglocarcinus stimpsoni

Note sur Tetralia nigrifrons Dana 1852

In the genus Tetralia of the family Trapeziinoe, the authors have separated or put in synonymy T. nigrifrons Dana with T. glaberrima Herbst. A study in details of morphologic characteristics of T. nigrifrons has demonstrated that the two species are different and it was an error putting the first in synonymy with the second. But it is no sure that the so-called T. nigrifrons is the species of Dana (1852).

Observations sur Orthopagurus Harmsi Gordon

During 1955 researching activities on Hapalocarcinidés in the Nhatrang Bay, the author collected blocks of Montipora verrucosa, genre Hexacoralliaire, and he found an Orthopagurus Harmsi Gordon, never harvested on the coral before. In this paper the author gave a detailed description.

Eumedoninae du Viet-Nam (Crustacea) (avec un bibliographie de la sous-famille)

This study provides elements for the revision of the subfamily Eumedoninae. The detailed description of the specimens led to the presence of characters that are common to different genera and many species. A bibliography and a list of genera and species of the subfamily identified in this bibliography is given.

Les Millepora (Hydrozoaires) de la Baie de Nhatrang

The importance of the variation of Millepora in connection with their habitat is so well known. Boschma (1948) describes some relationships between those variations and some ecological factors. The present paper establishes the taxonomy of Millepora living in the Nhatrang Bay and describes their distribution on the different parts of the coral reef of this bay. Some observations on the variations of some species in relationship with their habitat seem to agree with Boschma's opinion about the action of some ecological factors.

Note additionnelle sur les espèces de Chlorodopsis (Brachyures)

The present paper completes the authors’ studies (1958) on the species of Chlorodopsis of Viet-Nam. It gives observations on the new specimens collected previously and of a new species. It exposes the results of the observations on specimens communicated to the authors by the Museum of Paris, the Indian Museum of Calcutta and the Bishop Museum of Honolulu. These specimens include the syntypes of Chl. melanochira and Chl. Woodmasoni and some samples of another species not yet recorded on the Viet-Nam seashores. The taxonomic position of various species is revised and species maintained by Balss (1938) in the genus Pilodius are included in the genus Chlorodopsis. The authors give a new key to separate all the species of the genus Chlorodopsis.

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.

Note sur Branchiostegus tollardi (Chabanaud)

Latilus tollardi Chabanaud 1924 has been described for some specimens from the Nhatrang's market. The authors record a lot of new specimens of the same locality and give the illustration of one specimen. The species is probably a synonym of Branchiostegus sericeus Herre 1935 recorded from the Hong Kong’s market. Neither one nor other species have been figured before.

Sur quelques especes rares de Brachyures (Leucosidae) de l'Indo-Pacifique (2è partie)

In the first part, some rare samples of Leucosidae, belonging to the collection of Nhatrang Institute of Oceanography, have been studied; some of them are included in the subfamily Ebaliinae. This note examines various species of this subfamily which were not described in the previous study.

Directive cadre sur l’eau - Bassin Loire-Bretagne. Contrôle de surveillance dans les masses d’eau côtières et de transition. Actions menées par Ifremer en 2014

Le contrôle de surveillance 2014 pour la DCE appliquée dans les eaux littorales de Loire Bretagne a porté sur les 25 masses d’eau côtières (sur 39 au total) et les 16 masses d’eau de transition (sur 30 au total) retenues au titre du contrôle de surveillance. L’ensemble des résultats acquis, aussi bien sur les paramètres biologiques que chimiques, a permis de mettre à jour l’évaluation de l’état des masses d’eau affiché sur l’atlas DCE accessible sur la page web d’Envlit correspondante.
