The upper side of the whorls contain one smooth revolving keel nearly midway between the sutures, but a little nearer the periphery.

Above this on the body whorl are four smaller more or less beaded or crenulated keels, below it are two without nodosities, reaching the gently rounded periphery.

The base of the shell is supplied with nine rounded revolving ribs, those nearer the umbilicus with a tendency to beading.

The interspaces are about as wide as the ribs, which are crossed by slight elevations due to lines of growth.

The columella is emarginate, twisted, not thickened, ending in a round lump above the basal margin of the aperture.
