NHMUK 1903.7.1.2151 (2 shells; Fig. 17 F) from Kopamedza Peak, Naga Hills (figured in Godwin-Austen 1897: pl. 65, figs 6, 6 a); Godwin-Austen coll. Diagnosis. Shell dextral, ovate-fusiform, dull, whitish. Whorls ~ 7, well rounded; spire elevated-conical; suture wide, shallow. Teleoconch with very weak, narrowly and equally spaced radial ribs throughout. Penultimate whorl convex, equal in width to last whorl. Aperture circular; columellaris weak, small, directed downward. Peristome broadly expanded, double, multi-layered; outer peristome slightly broader than inner peristome; parietal callus thickened, expanded, nearly attached to suture. Columella straight; umbilicus closed. Distribution. This species is known from its type locality at Kopamedza Peak, Lahupa – Naga Hills, Manipur State, India, as well as from locations north of the Barail Range within the same state. Records from Myanmar lack precise locality data (Gude 1921), and the presence there has not yet been reconfirmed.
