Benthic foraminifera from 224 bottom samples collected between 5 and 805 m depth in the Gulf of Naples {Italy) have been studied. The quantitative analyses resulted in the identification of 356 species, most of which are illustrated. The purpose of the present paper is to bring together the systematics and the distribution of the thanatocoenoses. To define a more controlled autoecology of each species, we compared and integrated our data with those from other Mediterranean areas. The data set allowed us to identify the following groups of species: a) species characterizing discrete assemblages, which allowed the definition of the first bathymetric zonation in the Gulf of Naples; b) species dominant in areas characterized by peculiar chemico-physical conditions; c) species, poorly represented, but of bathymetric importance; and d) species occurring, within the Mediterranean Basin, only in the Gulf of Naples. In addition a new species, Quinqueloculina neapolitana, is described and illustrated.
