Distorsio ridens (Reeve, 1844)

Lewis (1972) designated a "lectotype" of D.
ridens - a specimen in the AMNH (Haines Coll.), and Emerson and Sage
(1990a, 1990d) correctly identified that shell with D. clathrata a
few years later. The latter authors mentioned D. robinsoni Petuch
but dismissed it as a mere form of D. clathrata (shorter spire and
siphonal canal). In our opinion D. ridens is actually D.
robinsoni, and the latter is specifically distinct from D.
