The last whorl is 75% of the shell height and the apex is pointed. The aperture has a white layer at the parietal side, the parietalis (the spiral ridge on the parietal region projecting into the interior of the shell) is usually strong. The columellaris (or internal lip of the shell aperture) is moderately or indistinctly developed. There is no umbilicus.
