Remarks.

This species was described based on specimens collected by H Mouhot from the Cuming collection. The original description included an illustration and one set of shell measurements. There are four specimens in the NHM collections from the Cuming collection with an original label in Pfeiffer’s handwriting stating the taxon name, collector and collection locality. The specimen that closely matches the illustration ans has a small label stating “Type” glued inside the umbilicus is figured herein (Fig. 10F).
