Los moluscos (Pelecypoda, Gastropoda, Cephalopoda, Polyplacophora y Scaphopoda) recolectados en el SE del golfo de California durante las campañas SIPCO a bordo del B/O “El Puma”. Elenco faunístico

Abstract

A total of 202 species (122 genera in 62 families) and 4 979 specimens of mollusks was collected in 24 bottom trawls on the continental shelf off the coast of Sinaloa, in the SE Gulf of California, Mexico. The trawls were made between 27 and 117 m depth during the SIPCO I, II and III cruises aboard the research vessel “El Puma” of the Universidad Nacional Autónoma de México in April and August 1981, and in January 1982. The material obtained belongs to five classes of mollusks: Pelecypoda, 55 species, Gastropoda, 140; Cephalopoda, 3; Polyplacophora, 3; Scaphopoda, 1 species. Some species (2 Bivalvia; 4 Gastropoda; 1 Cephalopoda) could not be identified but were recognized as distinct. The check list presented includes the material examined and the geographic distribution of all species. In addition, an illustration of each collected species is provided.
