 The abrupt increase of the antepenult whorl, and the 

 smoothness of the base towards the mouth, easily dis- 

 tinguish the species from S. Sankeyi. The ribs, 

 moreover, are coarser, and a second, though minute 

 parietal lamella, surmounts the principal one.

Our figure is uusatisfiictory : the body is usually 

 broader, and the mouth more oblique. The internal 

 lamella? cannot, of course, be represented on so small 

 a scale : they average with the teeth and denticles 

 about nine in number.
