Deep-water Raphitomidae (Mollusca, Gastropoda, Conoidea) from the Campos Basin, southeast Brazil
During the program “Environmental Characterization of the Campos Basin, RJ, Brazil”, carried out from 2001 to 2003,117 stations were sampled on the continental slope of the Campos Basin off southeast Brazil, by the Research Vessel“Astro-Garoupa”. The samples were taken on soft bottoms at depths from...
