The shell is small (maximum length 13 mm) and fusiform. The spire is high, consisting of one and one-fourth nuclear whorls and three convex postnuclear whorls. The suture is strongly impressed. The body whorl is of moderate size and fusoid. The aperture is of moderate size and ovate, with a relatively broad, shallow anal sulcus. The outer apertural lip is thickened and flaring at its margin; its inner surface bears seven strong denticles, recessed a short distance into the aperture. The columellar lip is entirely adherent and smooth. The siphonal canal is short, slanted to the left, and narrowly open. The body whorl bears eight strong axial costae. Spiral sculpture consists of 12 narrow, depressed cords, these persistent between the axial costae.
