The body whorl is heavy and broad. The aperture is broad, capacious, and ovate to subcircular, and the anal sulcus is not clearly defined. The outer apertural lip is simple and reflected. The columellar lip is entirely adherent. The siphonal canal is comparatively short, open, and distally recurved. The body whorl bears nine strongly raised axial laminae. At the shoulder margin the laminae are curved to form broadly open incipient spines. Spiral sculpture is lacking. Shell color is entirely white.
