REMARKS

Cowie & Thiengo (2003: 58) noted five lots totaling 36 specimens (in fact there are 37), which they considered to be syntypes. However, the name was made available from the plate and name, i.e. based on the single shell illustrated, which is therefore the holotype by monotypy. Among the 37 specimens, one shell has “type” written on it and its label says that it is the specimen figured. It matches the illustration of Crosse & Fischer perfectly. It is therefore the holotype. Sowerby (1909: 363) appears also to have identified this shell as the holotype. The other 36 specimens (MNHN 4455), one of which was illustrated by Fischer & Crosse (1890: fig. 9), have no type status.
