The shell is small (maximum length 11 mm) and biconic. The spire is high, consisting of one and one-fourth angled, tabulate nuclear whorls and five convex postnuclear whorls. The suture is weakly impressed and undulate. The body whorl is of moderate size, fusoid, and strongly constricted above the siphonal canal. The aperture is small, strongly emarginate, and subovate, the posterior margin flattened; the anal sulcus is narrow and shallow, and is extended to form a brief spout. The outer apertural lip is barely erect and minutely serrate; its inner surface bears five denticles, the second from the posterior end very large. The columellar lip is adherent at its posterior end, barely detached and weakly erect for most of its length; a series of pustules on the outer shell surface of the previous whorl is reflected on the columella. The siphonal canal is moderately short, almost closed, and bent to the left.
The body whorl bears seven or eight low varices. Additional axial sculpture consists of numerous fine lamellae, thrown into scalelike projections over the spiral sculptural elements. Spiral sculpture consists of eight major cords, six on the body and two weaker ones on the canal; there may be a single intercalary minor cord between each two major cords. Where the major cords intersect the varices, moderately prominent, transversely elongate nodules are formed.
Shell color is blue-black and blue-gray, or red-brown in sun-bleached specimens; the nodules are colored rosy pink. The aperture is purple or blue-gray, with white denticles and pustules. In faded specimens the nodules and the aperture are white.
