The shell is moderately large for the genus (maximum length 20 mm) and roughly fusiform. The spire is high, consisting of six angulate postnuclear whorls and a protoconch of undetermined nature. The suture is strongly impressed. The body whorl is moderately large and fusoid. The aperture is moderately large for the genus and ovate, with an erect peristome. The anal siphonal tubes are moderately long; each originates slightly closer to the earlier of the two bracketing varices and projects slightly posteriorly and dorsally. The siphonal canal is moderately long, closed, slightly bent to the right, and barely dorsally recurved.
The body whorl bears four low, oblique, marginally scalloped varices. The free edge of each varix bears four rounded, scalloplike lobes, these diminishing in size posteriorly, and a strongly anteriorly hooked spine at the shoulder margin. The shoulder of the shell in advance of this spine rises to form a brief partition above the aperture. The margin of the canal bears a single short, blunt projection medially. Spiral sculpture consists of weak, rounded swellings on the receding edge of the varix, these associated with the varical lobes.
Shell color is pinkish-white, with brown suffusions at the tips of the anal tubes and the siphonal canal and an ephemeral brown lino following the base of the body from whorl to whorl; an interrupted, rusty-brown band follows the shoulder. A thin, flat-white intritacalx covers the shell.
