Retusa (Cylichnina)

Gastropoda - Opisthobranchiata - Retusidae

Taxonomy
Cylichnina was named by Monterasato (1884) [Sepkoski's age data: T Than R]. It is extant.

It was reranked as Bullinella (Cylichnina) by Furon (1948); it was reranked as Retusa (Cylichnina) by Martin (1904), Glibert (1962), Palmer and Brann (1966), Mandic and Steininger (2003).

It was assigned to Scaphanderidae by Turner (1938); to Scaphandridae by Durham (1944), Harris and Palmer (1947); to Bullinella by Furon (1948); to Cylichnidae by Squires (1984), Squires (1987), Squires (1988), Squires and Demetrion (1992), Squires (1999); to Cephalaspida by Sepkoski (2002); to Retusidae by Todd (2001), Harzhauser and Kowalke (2002); and to Retusa by Martin (1904), Glibert (1962), Palmer and Brann (1966), Mandic and Steininger (2003).
