Syntype NHMUK 20170356 (2 shells; Fig. 4K, L). Remarks. This species was described from material in the Cuming collection, and the original description included only one set of shell dimensions.

The NHM collections contain a lot of two specimens from the Cuming collection with Pfeiffer's hand written label giving the species name and collection locality. The specimen that corresponds to the shell measurements in the original description and the illustration in Reeve (1863) is figured herein (Fig. 4K). Figure 4.
