|

Shell turbiniform, moderately high −spired, four to five teleoconch whorls; suture distinct, incised; whorls strongly convex and evenly rounded apart from smooth subsutural ramp that ends with distinct angulation at whorl periphery. The number of spiral cords on periphery varies between five and ten, and there are approximately seven spiral cords present on the base. The juvenile whorls are additionally ornamented by sturdy axial ribs well knobbed at the intersections with spirals. The axial ribs start right on the first spiral rib delimiting the ramp and lateral flank. The axial ribs weaken on the third whorl and fade out completely on adult specimens although this process seems to be heterochronous and variable forms are present.
