Pterocyclos marionae Preston, 1914: 22, with text figure.

Current generic position.

Pterocyclos Benson, 1832

Type locality.

Naga Hills [Assam, Arunachal Pradesh and Nagaland states, India].

Type material.

Syntype RBINS 524550 (1 shell; Fig. 8I), NHMUK 1911.10.12.20-21 (2 shells; Fig. 8J).

Remarks.

A unique name bearing type was not explicitly designated and the species description was not clearly based on one specimen. The original description included a single illustration and one set of shell measurements. The RBINS collections contain a lot with one specimen from the collection of P Dautzenberg with an original label stating “Type” and “fig.”. This specimen matches well with the shell measurements given in the original description and is figured herein (Fig. 8I). The NHM collections also contain another lot of two specimens with an original label stated “co-types”, and are also considered to be syntypes.
