The height of the shell attains 15 mm, its diameter 20 mm. The umbilicate shell has a globose-conic shape. The 6 to 7 whorls are encircled by numerous unequal, grained, partly pearly riblets. The convex base is sculptured with smoother riblets, their interstices cancellated. The umbilicus is deeply channelled. The aperture is rounded-quadrate. The columella is deeply sinuous, callous, terminating in an acute denticle. The outer lip is sulcate within, subcinereus or ashen-reddish, with scattered obscure spots on the upper whorls. The lip is thickened in adults and is silvery-pearly.[2]
