REMARKS

The shells match the original description and dimensions. Fischer-Piette (1950: 12) did not suggest any type status for these specimens, except that they are from the type locality (i.e. topotypes only). He figured one of them (Fischer-Piette 1950: pl. 1, fig. 7). He also indicated that they have operculae, which they do, whereas the original description said “opercule inconnu”, suggesting that these may not be the original material. However, despite these inconsistencies, and inasmuch as they were in the type collection of the Journal de Conchyliologie, we consider them possibly to be syntypes. They are surely the small juveniles of a larger species.
