REMARKS

The name is available from Férussac (1821a: 60; 1821b: 56) because it was accompanied by the single diagnostic term “coquille turriculée”. Férussac in Quoy & Gaimard (1825: 481) provided a brief description but no illustration. Labels in both lots indicate that the material was in the collection of Deshayes, and possibly therefore of Férussac. The five specimens are all more or less smaller than that described and illustrated by Deshayes (1851: 196, pl. 155, fig. 13) and therefore no lectotype is here selected and the specimens are considered here as only possible syntypes.
