Type locality.

unknown.

Type material.

Lectotype (design. n.), NHMUK 20130086/1 ( Fig. 7E; D =30.1 mm, H=25.5 mm, W=5), paralectotypes NHMUK 20130086/2-3 (2 shells; Fig. 7F; D =29.9 mm, H=25.8 mm, W=5; D=27.3 mm, H=23.7 mm, W=5).

Remarks.

The original description did not include an illustration or collection locality. Pfeiffer subsequently ( 1854a: 293, pl. 39, figs 20, 21) re-published the description and figured the species. There are three shells from Cuming’s collection with an original label in Pfeiffer’s handwriting. The specimen which most closely matches with the measurements given in the original description and the illustration in Pfeiffer (1854a) is here designated as the lectotype.
