J. Gründel and A. Nützel 2012The shell is very large and slender. The teleoconch whorls have a ramp which is not demarcated by a spiral furrow. The whorls are smooth. They embrace well below the ramp. The aperture is very high and narrow, only somewhat broadened abapically. It lacks columellar folds. The outer lip is convex. The protoconch is unknown.
