Les pagures du Viet-Nam. 1. Le genre Diogenes Dana

This first note deals with Diogenes of Group II (cf. Forest, 1952, p. 11). This group contains a number of highly variable species which are, in some cases, poorly characterized due to the vagueness of the original descriptions. Diogenes from Nhatrang belong to four different species but only one of them was identified with a species already described: Diogenes avarus Heller. The other three described and figured in this paper, are probably Diogenes Goniochirus, and D. leptocerus, D. serenei sp. nov.

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).

Les pagures du Viet-Nam. II. Sur quelques espèces du Genre Calcinus Dana

The collections of the Oceanographic Institute of Vietnam include several species of hermit crabs of the genus Calcinus Dana. Three of keys were studied by Fize and Serene (1955): C. herbsti Man, C. gaimardi H. Milne Edwards and C. latens Randall . The seventy specimens belong to four species. The first one, C. minutus Buytendijk, was described by Indonesia in 1937; the second one, represented by a single small specimen is related to C. spicatus Forest. Finally, two other are Calcinus vachonis sp. November and Colcinus pulcher sp. nov.
