The present study is based on the well-known publication “Caribbean Seashells” by Warmke & Abbott (1961); its data are not repeated here, but a large number of mainly small species were added. Most data from “Gegevens over Mariene Gastropoden van Curaçao” by De Jong & Kristensen (1965) have been included. Furthermore most of the photos of species in “A survey of the littoral Gastropoda of the Netherlands Antilles and other Caribbean Islands” by Coomans (1958) are reproduced. The figures of species treated by us and occurring in “Caribbean Seashells”, in “The Western Atlantic Marine Mollusks, described by C. B. Adams” by Clench & Turner (1950) or in “American Seashells” by Abbott (1974) are referred to.
