Type material.

Syntype NHMUK 20170369 (3 shells; Fig. 7F, G).

Remarks.

The species was described based on material from the Cuming collection. The original description did not include an illustration and only one set of shell dimensions was given. Pfeiffer (1869) re-published the description and illustrated a specimen. The NHM collections contain a lot of three shells from the Cuming collection with a label stated “Type”. The specimen that closely matches with the shell measurements, the illustration in Pfeiffer (1869) and has an “X” written on the shell, is figured herein (Fig. 7F).
