E. Poorman emphasizes the distinction of this species based on the varicose outer lip, pronounced anal sulcus and lamellose edge of the columellar callus. The latter two features are not particularly unusual in columbellids, but the varicose outer aperture edge is unusual, though it appears not to be present in all specimens.

The body whorl has a band of axially elongated dark blotches below the periphery and usually a separate row of spots on the base. The anterior tip of the shell is white, often with a spiral band of small dark markings. Aperture edge thickened, varicose in some specimens, with a few denticles internally and a couple large dark blobs on the dorsal aperture edge. Aperture edge with a shallow posterior sinus.

and was found in the same locations, though it was much less common. The shell is slightly smaller and stouter, with about one fewer teleoconch whorl and onehalf more protoconch whorls. Though there is overlap, these differences are both statistically significant; T = 3.70, P = 0.001, DF = 23 for the mean number of teleoconch whorls and T = 4.00, P = 0.002, DF = 12 for the mean number of protoconch whorls.
