Syntype NHMUK 1854.7.24.365 (2 shells; Fig. 1I, J).

Remarks.

The original description included one set of measurements. Later, Eydoux and Souleyet (1852) re-published the description and figured this species. Gray (1855: 19) made a list of type specimens of molluscs described by the late M Souleyet and housed in the NHM collections. There are two specimens with an original label stating the species name and collection locality. The specimen that closely matches the figure in Eydoux and Souleyet (1852) and is closest to the measurements given in the original description is illustrated in Figure 1I.
