The diameter of the shell is 15 mm. The depressed shell has a turbinate shape. The spire whorls are somewhat exserted, all showing a pair of peripheral keels, which are strongly, or subsipinosely crenulated. The whorls are encircled by a spiral series of granules above. The base of the shell is smooth. The umbilicus is of a moderate size, defined by a riblet. The peristome is strongly crenately varicose. The color of the shell is whitish, stained with chestnut.[1]
