Type material.

Lectotype (design. n.) NHMUK 1903.7.1.2783 (Fig. 9F), paralectotypes NHMUK 1912.4.16.644 (3 shells; Fig. 9G).

Remarks.

The original description did not contain any illustrations, and only one set of measurements was given. Godwin-Austen stated that the type series was from the Beddome collection. The NHM collections contain two lots that are considered to constitute the type series. Lot NHMUK 1903.7.1.2783 consists of a single specimen, collected by Muspratt, from the Godwin-Austen collection and has original labels giving the species name “nagaensis”, type collection locality and stating “TYPE”. This specimen is here designated as the lectotype to stabilise the name.

The paralectotypes consist of a lot of three shells, NHMUK 1912.4.16.644, from the Beddome collection, collected by Muspratt, with an original label stating the species name “nagaense”, type collection locality, the reference of the original description and is marked as “PARATYPES”.
