The five whorls are rounded, the first three transverselly ribbed and longitudinally striated. The remainder are transversely punctate-striate. The umbilicus is bordered by a rounded callus. The circular aperture has a channelled angular projection in front. The outer lip is simple, the margin acute.^[2]
