Diagnosis

Measurements (n = 10): SH 2.5–2.6 mm, SW 1.3–1.4 mm, Wh 6.0–6.5. Dextral, well rounded, regularly increasing, penultimate and body whorls nearly equal in width, suture impressed. Constriction at the middle of the parietal wall ( Fig. 9H View Fig ). One parietalis, moderate ( Fig. 5B View Fig 3 View Fig ). One vertical palatalis, which runs along the constriction, but does not reach the lower half of the whorl. No horizontal palatalis ( Fig. 9H View Fig ). Columellaris close to the umbilicus. Columellar tooth weak. Protoconch smooth, Wh approx 2.0, with small pits distributed all over, no radial ribs ( Fig. 5B View Fig 1 View Fig ). Teleoconch with dense radial ribs; about 8–10 ribs/ 0.5 mm on the penultimate whorl; 10–14 ribs/ 0.5 mm on the body whorl towards the aperture ( Fig. 5B View Fig 2 View Fig , B 4 View Fig ). Fine spiral striation present. Umbilicus closed. Aperture circular, parietal wall thin and straight. Peristome with two close lips; angular edge of the peristome straight; outer palatal lip rounded; basal lip along the columellar margin slightly curved; inner lip thin. Operculum paucispiral, corneous, thin, transparent, slightly concave, outer surface smooth, inner surface with raised edge at the central portion.

Remarks

Godwin-Austen (1892) gave the type locality as “South of the Barak River, between the Mao villages and Munipur” and noted that “from the number of specimens found, this appears a very abundant species; I never got anything like it in the Khasi Hills to the west”.
