The shell contains 9 whorls, of which 2 upper ones form a smooth, convexly-whorled nucleus.

The sculpture consists of numerous, rather narrow, axial ribs, about 20 stronger and weaker ones on the body whorl, that behind the peristome very strong and varix-like; these ribs run from one suture to the other on upper whorls, but are faint towards the base of body whorl, and disappear on the siphonal canal, which is spirally lirate.

The upper part of the whorls is very faintly spirally striated.

The columellar margin is tubercled above, then regularly concave and conspicuously enamelled.

The interior of the aperture shows a white layer of enamel near peristome and 3 brown blotches at its margin, corresponding to the external bands.
