Whorls 5, rounded, the last cylindrical, descending gradually towards the aperture, and furnished, 7–10 millimetres behind the peristome, with a short open sutural tube, projecting forwards and upwards, not touching the penultimate whorl. Aperture diagonal, circular, peristome double, both lips continuous, the inner slightly expanded, curved back into a shallow angular sinus at the suture, the outer expanded, and inverted upon the upper and dextral margins, rising near the suture into a compressed wing, which is attached throughout on the left side to the penultimate whorl. Operculum horny, concave within, convex without, flattened near the centre, 2 or 3 outer whorls furnished with a free spiral testaceous lamelliform border ( Blanford, 1866).
