The shell contains approximately 6.5 moderately convex whorls, with inconspicuous oblique growth lines. The body whorl ascends slightly at its termination. The aperture is subovate and is white within. The peristome is rather broadly expanded and slightly reflected. The columella isvertical and is expanded above. ^[2]
