The size of an adult shell varies between 65 mm and 163 mm. The shell is rather narrow and has an elevated spire. The color of the shell is chocolate-brown, covered by elevated close revolving lines of darker color. The surface is irregularly overlaid by subtriangular white spots, some of which are very large. The operculum is a very minute square on the dorsal surface of the hinder part of the foot.
