Kelantan, Malay Peninsula [Kelantan, Malaysia].

Type material.

Syntype NHMUK 20170357 (3 shells; Fig. 5A, B).

Remarks.

The species description does not include an illustration, but later, Sykes (1902b) cited the species name and illustrated a shell of this taxon. The NHM collections contain a lot of three specimens from the Sykes collection. There is a specimen that exactly matches with the illustration in regard to the brownish zigzag streaks on the last whorl, and with the shell measurements given in the original description plus it has “Type” written on the shell. It is figured herein (Fig. 5A).
