Type material.

Syntype NHMUK 20170351 (3 shells; Fig. 5H, I).

Remarks.

This species was described based on specimens from the Cuming collection, and was not illustrated in the original description. Reeve (1863) re-published the description and figured a specimen from the Cuming collection. The NHM collections contain a lot of three shells from the Cuming collection with a label in Pfeiffer’s hand written label stating the taxon name and collection locality. The specimen which closely matches the illustration in Reeve (1863) and the shell measurements given in the original description is figured herein (Fig. 5H).
