(Original description) The small, translucent white shell is very thin and fusiform.

The axial sculpture, in addition to lines of growth of (on the penultimate whorl consists of about twenty-six) fine, sharp, narrow lamellose riblets following the lines of growth, beading the presutural band, angulated at the shoulder and obsolete on the base, with wider, excavated interspaces.

These are crossed by very numerous, fine, close-set, spiral threads, slightly coarser on the siphonal canal and minutely feebly reticulated by the incremental lines.

The outer lip is thin, simple, with a wide sulcus occupying the space between the suture and the shoulder, in front of which it is arcuately protractive.

[citation needed] There is also a variety with stronger sculpture, shorter and stouter shell, and a distinctly recurved canal.
