Sculpture consisting of rather distant, irregular, and low spiral lirae, 2 to 3 on the spire-whorls, 5 on the last whorl above the periphery, and about 5 upon the base, crossed by numerous oblique growth-lines and distant membranaceous plaits, which are easily rubbed off. Colour pale brown, sometimes with a narrow pale band at the periphery of the last whorl and 1 around the middle of the base. Epidermis thin, horny, not shining. Spire acutely conical, the apex obtusely rounded, higher than the aperture, Protoconch small, papillate, of 2 convex, dark-brown and shining whorls, the first with a few faint spiral striae, the second closely radiately striate. Whorls 5,5, rounded, the last distinctly angled at the periphery ; base flatly convex, depressed round the umbilicus, but not keeled. Suture impressed. Aperture slightly oblique, subcircular, angled above. Peristome thin, regularly arched, callous within, continuous over the parietal wall; notch at the suture but slight.
