Mergui, Birmah. 
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.

Despite of its supposed habitat, there can be no 
doubt as to the generic allocation. We have figured 
Benson’s own examples.

Our figure is unsatisfactory : the body is usually 
broader, and the mouth more oblique. The internal 
lamellte cannot, of course, be represented on so small 
a scale : they average with the teeth and denticles 
about nine in number.
