Type specimens.

Syntypes NHMUK 1906.1. 1.2207 [re-registered in error as 1985138] (6 shells; Fig. 13 A – C View Figure 13 ). ex. W. T. Blanford ex. Godwin-Austen collection from Akouktoung , Pegu .

Shell elongate, turreted, and regularly attenuated; apex rounded; subsequent whorls nearly smooth and with coarse radial ridges near suture. Suture impressed and whorls flattened convex. Aperture broadly ovate; columella strong, concave, and truncated.

Distribution.

The species is currently known from its type locality, in which the modern name is Akauk Taung [hill, ~ 18 ° 30 ' 33.7 " N, 95 ° 06 ' 48.5 " E], south of Htone Bo (or Tonbo) Village, Padaung Township, Pyay District, Bago Region].

Remarks.

The original description did not include an illustration, and only one set of measurements was given. Godwin-Austen’s description was based on one lot of specimens which clearly stated ‘ Type No. 2207.06. 1.1 B. M. ’ ( NHMUK 1906.1. 1.2207). There are six specimens from the NHMUK type collection with the original label stating ‘ Type’. The specimen that has a similar shell measurements as given in the original description and with pink wool inside the shell is figured herein (Fig. 13 A View Figure 13 ). Other shells from the same syntype lot are also illustrated (Fig. 13 B, C View Figure 13 ).
