Type locality.

Khao Sabap, Siam [Plieu National Park, Khlung District, Chanthaburi Province, Thailand].

Type material.

Holotype NMW 1955.158.24924, paratypes NHMUK 1949.6.7.1 (2 shells; Fig. 12D), NHMUK 20170372 JE Cooper coll. Acc. no. 2150 (1 juvenile).

Remarks.

The original description included an illustration, one set of shell measurements, and was clearly based on more than one specimen. The author indicated that the ‘Type’ was kept in the JR le B Tomlin collection and ‘Paratypes’ were housed in the NHM collections. The holotype was clearly designated and is housed in the JR le B Tomlin collection (later transferred to the NMW in Cardiff). The NHM collections contain two lots, consisting of three shells in total, both containing an original label stating “Paratype”. The collection locality matches with the original description. Therefore, we consider these specimens as paratypes.
