It is white and semipellucid. The spire is raised, the suture is distinct. 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.〔(Proceedings of the Zoological Society of London 1867 p. 911 )〕
