The shell is of moderate size for the genus (maximum length 30 mm) and stoutly fusiform. The spire is high, consisting of two and one-half nuclear whorls and five subangulate to convex postnuclear whorls. The suture is obscured by the succeeding whorl. The body whorl is moderate in size and fusoid. The aperture is ovate and moderately large; the outer apertural lip is erect and marginally crenulate; its inner surface is adherent at its upper extremity, detached and erect below. The columellar lip is smooth, gently arcuate, and entirely adherent. The siphonal canal is short, broad, closed, and distally recurved.
The body whorl bears three prominent, rounded varices with more or less well-developed tubercles at their points of junction with the major spiral cords. Intervarical axial sculpture consists of a single prominent costa. Spiral sculpture consists of seven major body cords and, below these, three or four secondary cords. The canal bears a single primary cord and two anterior secondaries. Numerous scabrous threads fill the cord interspaces. The major cord at the shoulder margin is variable in its development of tubercles.
Shell color is brown, with the spiral cords gen-erally white. The edges of the varices may also be white, sometimes with a paler band at the shoulder margin. The aperture is cream-colored to yellow-ochre.
