Current generic position.

Cyclotus Swainson, 1840

Type locality.

Trusan Island [Terusan Island, Sabah, Malaysia].

Type material.

Syntype NHMUK 1889.12.7.22 (1 shell; Fig. 12H).

Remarks.

The species description was clearly based on more than one specimen. The original description included an illustration of a single specimen and gave two sets of shell measurements. The NHM collections contain a lot consisting of a single shell with an original label stating “type”. This shell matches with the illustration and the shell sizes correspond well with the measurements of the specimen cited as "Size of shell drawn", in the original description.
