(Original description by Adams) The brown, convex, imperforate shell has a suborbicular shape. It is transversely costulate. The riblets are close-set, and noduled. The interstices are very finely longitudinally striated. The spire is rather prominent. The rounded whorls are costate. The subcircular aperture is pearly within.[2]
