Discopsis

Rolán & Rubio (2002: 46) hold Discopsis as a valid genus, distinct from Cochliolepis Stimpson, 1858, 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. ==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. ==Species==
