Spirals—there is a blunt carination in the middle of the whorls, below which the surface is scored with flat threads parted by slight irregular lines.

They are yellow and conical, and are microscopically scored by minute narrow raised lines which are straight above, but below slope very obliquely to the left.

The body whorl is large, tumid, and has a swollen base prolonged into a broad triangular lop-sided snout, which is not at all emarginate in front.

The outer lip is thin, flatly arched, with a deep broad sinus which lies up at the very suture, and with no shelf at the insertion.

Its line is barely convex on the body, subangulatedly concave at its junction with the columella, which is longish, oblique to the left, and slightly truncate at the point.
