The surface is strongly spirally ribbed, the ribs being rendered more or less conspicuously granular by oblique, decussating transpiral grooves. The lowermost spiral rib in each whorl of the spire is more strongly raised, but at the periphery of the body whorl there are two such strongly marked spiral ribs, separated by a deep narrow groove; the lower surface is not quite flattened, and the wide circular umbilicus is the centre bears a toothed margin as usual.
