126 HELIC1D2E. 



Born, and H. carnicolor, Menke, yet we feel compelled 

 to regard it as similar and not identical, a member of a 

 group such as is usually found in particular geographi- 

 cal regions. It is doubtless the shell alluded to by Mr. 

 Forbes, in his catalogue of species common to both sides 

 of the Atlantic, as If. Pisana, which it greatly re- 

 sembles, especially in the color of the aperture. A 

 comparison of the base and other characters will show 

 their difference. It cannot be confounded with any 

 other North American species. [GL] 



b. Aperture toothed.
