The shell shows prominent spiral ridges, of which there are three on the main part of the body whorl, and two slighter ones at the base, and two ridges on the spire whorls. They are crossed obliquely by sharp longitudinal ribs, extending to the base. Their intersections with the spiral sculpture appear nodulous. The columellar tooth is small and remote. The umbilicus is narrow but distinct.^[3]
