'''''Discopsis''''' is a genus of small sea snails, marine gastropod mollusks in the family Tornidae.<ref name="WoRMS">Bouchet, P.; Gofas, S. (2014). Discopsis de Folin, 1870. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=138558 on 2014-12-10</ref>
==Taxonomy== Rolán & Rubio (2002: 46) hold ''Discopsis'' as a valid genus, distinct from ''Cochliolepis'' <small>Stimpson, 1858</small>, on the grounds that the latter belongs in the family Vitrinellidae and the former in Tornidae. This should be reevaluated in the perspective that both families are considered synonyms. Adam & Knudsen (1969) may have been right in placing the West African species in ''Cochliolepis''.<ref name="WoRMS" />
==Description== (Original description in Latin) The shell is discoid and very depressed, with a distinct umbilicus. The aperture is strongly oblique, and its margins are joined across the penultimate whorl by a thickened siphonal canal. <ref>[https://www.biodiversitylibrary.org/item/108784 Folin L. de & Périer L.
