NHMUK 1903.7.1.2191 (14 shells; Fig. 20 D) from South Burrail; Godwin-Austen coll. Diagnosis. Shell dextral, ovate-fusiform, translucent, whitish. Whorls ~ 7, well rounded; spire elevated conical; suture wide, shallow. Teleoconch: earlier whorls with strong, narrowly and equally spaced radial ribs; penultimate and last whorls with slightly wider-spaced radial ribs. Penultimate whorl convex, slightly wider than last whorl. Aperture circular; columellaris weak, directed downward. Peristome expanded, double, multi-layered; inner peristome slightly broader than outer peristome; parietal callus thickened. Columella straight; umbilicus closed. Distribution. This species is known from its type locality in the Barail Range, Manipur State, India. Records from Myanmar, however, lack precise locality data (Gude 1921), and the presence there has not yet been reconfirmed. Remarks. There are three syntypes housed in The Manchester Museum, University of Manchester (EE. 3511 / 130) (McGhie 2008).
