The shell is of moderate size (maximum length 30 mm) and rhomboid to fusiform. The spire is high, consisting of three and one-half polished, horn-colored nuclear whorls and six angulate postnuclear whorls. The suture is somewhat indistinct. The body whorl is moderate in size and fusoid. The aperture is comparatively small and ovate, with an indistinct anal sulcus. The outer apertural lip is erect and finely dentate, its inner surface weakly crenulate. The columellar lip is adherent above, detached and erect below. The siphonal canal is moderately long, narrowly open to the right, and dorsally recurved.
The body whorl bears five or six spinose varices. Additional axial sculpture is lacking. Spiral sculpture consists of primary, secondary, and tertiary cords; on the shoulder is a medial secondary cord flanked on each side by a pair of tertiaries; the body bears five primary cords alternating with tertiaries; the canal bears four secondaries. In addition, the surface of each primary cord is incised by five to seven fine grooves. Where the cords intersect the varices, short to moderately long, sharp, open, slightly foliated spines are developed. The entire shell surface is finely, scabrously laminate.
Shell color is generally white, stained with orange-brown to orange-ochre, particularly on the varical spines and on one transverse band, this medial on the body.
