Description

The small shell is very solid, subcylindrical or claviform. The sculpture consists of nodose ribs that do not attain the suture, and fine spiral threads which are most dense at the summit of the whorl. There is no epidermis. The protoconch consists of two smooth and elevate whorls. The aperture is wide, without varix or internal armature. The outer lip is simple. The wide sinus is U-shaped, its right margin resting on a massive insertion callus. The fasciole is indistinguishable. [4]
