This species is remarkable for the compression of the upper part 

 of the whorl, more marked than in any other species.

 above, where it turns inward, is not applied to the epidermis but

The color and striation is the same as in H. navicula, but H.per- 

 uviana is more swollen, less oblong, and the columella is elevated in 

 a sharp plate above, not appressed as in the European species. The 

 three stomach-plates are smooth. PI. 41, fig. 27 represents the 

 synonymous H. natalensis Sowb., the assigned locality of which is 

 evidently incorrect. Orbigny's figures (copied on my plate) are 

 double natural size.
