Protoconch conical, consisting of three convex whorls, first 2 ½ whorls smooth with keel just above abapical suture. Last quarter whorl with three spiral ribs, one on the keel and two adapically of this. Transition to teleoconch fairly sharp. Teleoconch whorls convex, evenly rounded, weakly bicarinate with nearly continuous transition to base. Aperture subcircular with strong varix at outer lip and well developed callus and straight and sharp columellar fold partly hiding narrow umbilicus. No teeth or columellar folds present. Siphonal canal only weakly developed. Teleoconch sculpture initially consisting of three spiral ribs and approximately 12 coarse, slightly opisthocyrt transverse ribs, increasing in number to around 20 on fourth whorl and about 35 on fifth whorl. Sinus of transverse ribs located between two keels. Number of spiral ribs increasing gradually with ontogenetic growth. Low and coarse tubercles are formed at crossing points between transverse ribs and three to four primary spiral ribs, one or two of them located at adapical suture, while last two are found at keels. Base nearly smooth or covered by weak spiral ribs.
