Shell pure white, turretted, subfusiform; whorls seven, inducing a blunt protoconch of two smooth rounded whorls; spire whorls convexly angular, girt with a row of distant nodules at the periphery, and a smaller row at the suture, on the lower part of the whorl is a somewhat nodulous keel, and between the two upper rows on the flatly sloping shoulder are four narrow raised line. The body whorl has about 15 lirae on the base, the first, opposite the suture, being nodulous; some of these lirae form ridges within the aperture; mouth squarely oval, opening into a short wide canal; lip thin, angled at the upper fourth: in profile it shows a deep trigonal sinus between the suture and the angle, and is then convex; inner lip arched, callously expanding over the columella.
