Descrição original:

(Pilsbry, 1958: 83-84): “The shell is dextral, cylindric, the apical fourth tapering to a rather obtuse summit. The tapering whorls are moderately convex; the last five whorls are flat, the last whorl with a projecting peripheral keel, concave above it and deeply concave at the base.

Sculpture of close, strongly oblique, straight, fine striae, remaining distinct on the last few whorls only. The aperture is strongly oblique, subtriangular, the basal margin straight, outer margin curved slightly forward, inner margin formed of a strong spiral callous ridge, truncate at the columellar base and spirally ascending the axis within, coiling around a small but distinct central cavity which viewed from the base forms a sort of false umbilicus.”
