Description The length of the shell attains 16 mm.
The elevated spire is acute, with a ridge below the sutures. The 8 longitudinal ribs are rounded, oblique, crossed by close strong striae, and terminate above on the periphery. The color of the shell is yellowish brown with two chestnut bands, or the lower one broader so as to cover the lower portion of the body whorl. The anal sinus is small, but rather deep. The shell shows two decided varices on the body whorl and one on the penultimate whorl.G.W. Tryon (1884) Manual of Conchology, structural and systematic, with illustrations of the species, vol.
