The protoconch is usually lost with the first one or two following whorls, so that the apex (as in our figure) seems somewhat blunt, but when perfect, though short, it is quite acute.

The sculpture consists of 12-15 transverse rounded ribs, beginning at or near the suture and continuing over the periphery, becoming obsolete on the base of the whorl.

The suture is distinct, undulated by the ribs, not channelled The whorls are full and rounded, the last constricted at the base.

The throat is strongly lirate, with 8-10 elevated threads ending a little way within the edge of the outer lip, which is crenulated by the sculpture.

The siphonal fasciole is strong, enclosing with the reflected columella a moderate, not very deep umbilical pit.
