Type material.

Possible syntype NHMUK 20160354 (3 shells; Fig. 13C, D).

Remarks.

The original description of this species included an illustration. Later, Pfeiffer (1853b) and Reeve (1863) re-published the description and figured this species based on material in the Cuming collection. The NHM collections contain a lot of three shells from the Cuming collection with original labels giving the taxon name and citing the illustration "f. 312, 313". The specimen in the Cuming collection matches well with the illustration in the original description, Pfeiffer (1853b) and Reeve (1863). However, Sowerby I did not clearly state that the species description was based on specimens from the Cuming collection. Therefore, we consider this lot to be possible syntypes.
