The shell is of moderate size (maximum length 110 mm) and broadly fusiform. The spire is mod-erately high, with six to eight weakly shouldered postnuclear whorls and a protoconch of undetermined nature. The suture is weakly impressed and generally obscured by the succeeding whorl. The body whorl is large and solid. The aperture is ovate, with an inverted-V-shaped anal sulcus, this delimited parietally by a spiral ridge extending into the aperture. The outer apertural lip is erect and finely denticulate, and projects briefly beyond the thickened varix; its interior is lirate, each lira ending in a labial denticle (a primary labial tooth is lacking). The columellar lip is entirely adherent. The siphonal canal is moderately short, broad, moderately open, and weakly recurved distally.
The body whorl bears four or five prominent spinose varices and a single axial ridge in each intervarical space. Spiral sculpture consists of numerous major and minor cords, all of these covered with fine, scaly threads. Where the cords intersect the varices, short foliated spines are developed, the shoulder spine the longest. Immediately below this a slightly weaker cord ends in a smaller, ventrally bent spine. Below that is a large straight spine, followed by a second smaller, ventrally bent spine and two large straight spines.
Shell color is white, with more or less brown marking on the spiral cord and spines. The interior of the aperture is porcelaneous white.
