„This species is well distinguished by the fine longitudinal riblets, which at the upper 

 extremities give a finely denticulate appearance to the deep suture. The Single speeimen 

 under exaraiiiation exhibits two denticles at the upper part of the uperture upon the wall 

 of the body whorl, one uear the upper end of the upper lip, the other aear it but fiirther 

 within the mouth. The labrum is conspicuously siuuated above near the suture and has a 

 tubercular thickening within below the sinus." — Smith.

,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.
