S52 MR. E. A. SMITH ON NEW SPECIES OF LAND-SHELLS. 



This species is readily distinguishable by the shouldered 

 character of the two last whorls, and the crispate keel which 

 marks the cingulation, and the second carina upon the body-whorl. 

 The above description is taken from smaller specimens than 

 the two described by Colonel Grodwin- Austen. The latter 

 have the same peculiar crispate keels which I have described, 

 but, having developed an additional whorl, have a different aspect 

 as regards form.
