The shell is stout, shining, milk-white, with irregular, flammulated spots of rust color, which are densest about one-third of the distance between the
sutures anterior to the summits, where they form an almost continuous band. The length of the shell varies between . (The whorls of the
protoconch are decollated.) The ten
whorls of the
teleoconch are weakly rounded, slightly shouldered and faintly crenulated at the summit. They are marked by lines of growth, which are somewhat variable in strength, the strongest being on the side of the crenulations. The sutures are well impressed. The periphery is marked by a moderately strong, spiral sulcus. The base of the shell is rather long, and is crossed by many lines of growth. The
aperture is elongate-pyriform, and rather compressed laterally. The posterior angle is acute. The
outer lip is thin. The
columella is short, and heavy. It is bounded by a low, strong basal fasciole, bearing three oblique folds, the posterior one of which is lamellar and situated a little anterior to the insertion of the columella; the other two folds are much less strongly developed and more oblique. The parietal wall is covered with a thin callus. ==Distribution==
