Type material.

Syntypes NHMUK 20130089 (2 shells; Fig. 13A; D =43.5 mm, H=32.1 mm, W=5; D=47.0 mm, H=37.3 mm, W=5)

Remarks.

The original description did not include an illustration but Reeve (1861: sp. 2) subsequently re-published the description with illustrations of a specimen from the Cuming collection. The NHM collection contains a lot of three specimens’ from the Cuming collection labelled "Malay Peninsula". A label reads "Mr. Benson has also sent me his Malayanum and the true volvulus for comparison ….”. Two of the three shells are close to the measurements and description in the original description and the label, presumably written by Cuming, indicates that these are the three specimens sent to Cuming by Benson, of which two without opercula are syntypes. The third specimen with an operculum being what Benson considered to be ' volvulus ' and not a member of the type series of ' malayanus '. There is a further lot from "Pulo Penang" housed in the University Museum of Zoology Cambridge with original Benson labels including one specimen labelled by Benson as ‘Type’.
