the former it can be distinguished by the slightly more produced 

 spire and less convex whorls, much less everted last whorl, smaller 

 aperture, even more evenly circular, and in a marked manner by 

 the sinjile instead of double peristome; the parietal callosity is 

 •quite different, being comi)ressed, vertical, and more lateral and 

 produced ; the incised canal at the columella is also more covered 

 by the triangular callosity, above which it is less compressed and 

 more evenly expanded : from P. artata by its si/e, proportions, 

 and additional whorl, imt especially by the quite different charac- 

 ters of the two callosities; the parietal callosity especially is quite 

 different, being much longer (it readies beyond the iniddle of 

 the last whorl), more vertical, and much more laterally inclined ; 

 indeed it extends further back than the'peristome.

"This handsome species is singular on account of the great 

 development of the callus, which runs up the penultimate whorl 

 two-thirds of its height, forming, with the prolongation of the 

 outer lip, a channel leading to the incision at the top of the 

 .aperture." (^Benson.)
