, a finer liration on the straight columella and the slightly longer spire. The slight sinus towards the lower part of the incrassate outer lip is comparatively conspicuous. It is white with red dots between the whorls. It contains 8 whorls, angulated in the upper part and slightly convex below. It shows narrow sharply angulated ribs, 10 on the penultimate whorl and 11 in the body whorl. The ribs are crossed by fine, flattened striae. The narrow aperture measures about half the total length of the shell. Smith E.A. 1884a. ''Diagnoses of new species of Pleurotomidae in the British Museum''. Ann. Mag. Natural History 14: 317-329.
