The shell is small (maximum length 20 mm) and fusiform. The spire is high, consisting of two and three-fourths convex nuclear whorls and five shouldered postnuclear whorls. The suture is in-distinct or weakly marked. The bodywhorl is of moderate size and fusoid. The aperture is small and ovate, with an indistinct anal sulcus. The outer apertural lip is erect and coarsely crenulate at its margin. The columellar lip is adherent above, detached and somewhat erect below. The siphonal canal is long, moderately open, and dorsally recurved.
The body whorl bears six weakly spinose varices. A varical expansion forms a webbing between the spines to about one-half their length. Intervarical axial sculpture is lacking. Spiral sculpture consists chiefly of four major cords on the body, these noticeable only over the varices, where they are finely incised by five to nine fine grooves. Alternating with the major cords are pairs of threads, and a series of four or five single threads occurs on the anterior end of the body. The canal bears two inconspicuous minor cords. Where the spiral elements cross the varix, low, sharp, dorsally recurved spines are formed. The entire shell is covered with weak scabrous laminae, these most prominent on the cords and on the leading edge of each varix.
Shell color is pale orange to yellow ochre-brown.
