editThe length of the shell attains 13.7 mm.
(Original description) The small shell has an abbreviated fusiform shape. It is dingy white and marked spirally by an inconspicuous band formed of three reddish-brown lines more or less interrupted on the basal and the preceding whorl. The shell contains five whorls angulated above and on the body whorl, rounded below the angle, with a shallow sulcation beneath. The surface is covered with rounded and irregular ribs, which are inconspicuous or obsolete on the upper whorls. The shell is longitudinally marked with from seven to nine irregular rounded ribs, which at the edge of the angle (which is somewhat carinated). They are broken into angular or pointed knobs or blunt spines. The aperture is ovate, angulated above and white within. The outer lip has five or six tubercles internally.
