The size of an adult shell varies between 20 mm and 45mm. The upperportion of the whorls are smooth and concave, with a sutural band of tubercles, sometimes becoming spinose. The periphery of the shell is angulated, and tuberculate, as well as the body whorl below it. This is caused by rudecurved longitudinal ribs crossed by the revolving sculpture. The color of the shell is lightyellowish brown, sometimes fasciated. The aperture is occasionally light violaceous, but mostly white. This species varies much in form and in the degree of development of the tubercles and spines.
