Type material.

Syntype NHMUK 20170350 (3 shells; Fig. 8B, C).

Remarks.

This species was described based on specimens collected by H Low from the Cuming collection. In the original description, only one set of shell measurements was given. In 1869, Pfeiffer re-described and illustrated a single specimen from the Cuming collection. The NHM collections contain a lot of three shells from the Cuming collection with Pfeiffer’s handwritten label stating the taxon name, collector and collection locality. The specimen that matches well with the shell dimensions in the original description and the illustrations in Pfeiffer (1869) is figured herein (Fig. 8B).
