„This species is well distinguished by the öne longitudinal riblets, which at the upper 
extremities give a finely denticulate appearance to the deep suture. The single specimen 
under examination exbibits two denticles at the upper part of the uperture upon the wall 
of the body whorl, one near the upper end of the upper lip, the other uear it but further 
within the mouth. The labrum is conspicuously sinuated above near the suture and has a 
tubercular thickening within below the sinus.“ — Smith.

tudinis totius testae vix aequans, subquadrata; peristoma haud incrassatum, antice leviter expansum; colu-

„This species has rather convex whorls, is finely striated, and has a deepish suture. 
The outer line is scarcely thickened and does not exhibit the sinus at the upper part which 
is characteristic of the genus. In form and general appearance, howewer, it agrees very 
well with the type of the group, S. fastigiata, Morelet. It also bears some resemblance 
to S. buchholzi, of Martens, from the Cameroons, but is considerably smaller, and has 
shorter aud rather more convex whorls.“ Smith.
