Cyclostremiscus is a genus of small sea snails in the family Tornidae. [1]
Rolán & Rubio (2002: 46) hold Discopsis as a valid genus, distinct from CochliolepisStimpson, 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. [1]
Species within the genus Cyclostremiscus include: [1]
Crassispira is a genus of small predatory sea snails with narrow, high-spired shells, marine gastropod mollusks in the family Pseudomelatomidae. They first appeared in the fossil record approximately 48.6 million years ago during the Eocene epoch, and still exist in the present day.
Teinostoma is a genus of minute sea snails, marine gastropod mollusks or micromollusks in the family Teinostomatidae.
Tornidae is a family of very small and minute sea snails with an operculum, marine gastropod mollusks in the clade Littorinimorpha. This family used to be known as the Vitrinellidae. Iredale has shown that the family Adeorbidae Monterosato, 1884 should be called Tornidae
