Whorls weakly convex, separated by shallow but well marked suture. Whorl height corresponding to less than half the width. Whorl periphery located on lower third of whorl. Transition to convex base gradual. Columella fairly short, weakly concave with no columellar folds. Inner lip rather strong, well defined, smooth. Outer lip thick, flat and sharply cut, inside smooth. Growth lines opisthocline, nearly straight.
