The shell is moderately large for the genus (maximum length 40 mm) and fusiform. The spire is high, consisting of a bulbous, asymmetrical protoconch of one and one-half whorls and five or six shouldered postnuclear whorls. The suture is weakly impressed. The body whorl is of moderate size and fusoid. The aperture is of moderate size and ovate, with a narrow, moderately shallow anal sulcus. The outer apertural lip is more or less erect and weakly crenulate. The smooth columellar lip is detached and erect anteriorly, and forms an adherent, moderately well-developed callus posteriorly. The siphonal canal is moderately long to quite long and slender, narrowly open, and bent slightly to the left.
The body whorl bears nine or more thin, lamellate, spiny varices. Spiral sculpture consists of seven or eight weak cords, four or five on the body and three on the canal. At the intersections of these cords and the varices, short, subacute, open, weakly dorsally recurved spines are developed.
Shell color is translucent blue-white, covered by a thin, flat-white intritacalx.
