They are on the upper whorls distinctly granulose, on the last almost entirely smooth. The 6 to 7 whorls are rather rounded with a convex base, the last one is scarcely angled. The margin of the narrow umbilicus is dentate. The columella is very oblique, not solute above and terminates below in a simple, small denticle. The outer lip is thickened within with five folds but near the edge with numerous wrinkles.
