The size of the shell varies between 70、105 mm（2.8、4.1英寸）. The color pattern of the shell varies from very light brownish to purple-brown. Some specimens contain only 6 whorls instead of 7 as in the holotype. The upper whorls are smooth, then follows the body whorl with scarcely 2 rows of granules, instead of 7 or 8. Towards the keel it has very irregular radiating ribs, which leave however a nearly smooth zone above the keel, with only a few spiral striae.
The base of the shell is less convex than the upper part. Some specimens lack the rose-coloured line round the umbilical callosity. The aperture is oval, thick, with the nucleus in the external lower corner. The outer surface is slightly rugose, by irregular wrinkles, almost parallel with the basal margin of the operculum. The nucleus is marked by an olive spot.
