NHMUK 1903.7.1.2126 (7 shells; Fig. 16 B) from Prowi, Lahupa, Naga Hills (figured in Godwin-Austen 1897: pl. 64, fig. 4); Godwin-Austen coll. Diagnosis. Shell dextral, ovate-fusiform, translucent, pale brownish. Whorls ~ 7, well rounded; spire elevated-conical; suture wide, shallow. Teleoconch: earlier whorls with weak, narrowly and equally spaced radial ribs; penultimate and last whorls with very weak radial ribs to nearly smooth surface. Penultimate whorl convex, slightly wider than last whorl. Aperture circular; columellaris very strong, sharp, directed downward. Peristome expanded, double, multi-layered; outer peristome slightly broader than inner peristome. Columella curved; umbilicus closed. Distribution. This species was originally known from its type locality at Prowi, Lahupa-Naga Hills, Manipur State, India, and has also been recorded from Tellizo Peak, Anghami – Naga Hills, Manipur State, India. The record from Myanmar, however, lacks an exact locality (Gude 1921), and the presence there has not yet been reconfirmed.
