The conic spire is acute. The six whorls are convex, striate and spirally lirate. The ridges are unequal, wider than the interspaces, frequently with interstitial lirulae. The large aperture lis oval and white within. The outer lip is frequently green-tinged and is fluted. The arcuate columella is deflexed and dilated at its base.

The circular operculum is flat or slightly concave within. It contains four whorls and a subcentral apex. The outer surface is convex, brown, coarsely granulose in the middle, paler and more finely granular at the margins.^[2]
