impressed ; aperture scarcely oblique, depressed, transverse, 

 lunate ; peristome simple, acute, sinuate, the columellar mar- 

 gin very rapidly and narrowly reflected over, and almost 

 entirely covering the very small perforation. 

 Diam. maj. 12^, min. 11, alt. 5 mill. 



Habitat. — "The Anantehely Mountains, which are a local 

 spur of the Alleghany Mountains in North Carolina, just where 

 that State touches Georgia and Tennessee." Bishop Elliott ! 



A single specimen of this very interesting species was found 

 in the locality above mentioned, by Bishop Elliott, in whose 

 cabinet I noticed it some months ago. In sculpture it is closely 

 allied to II. indentata Say, of which it might almost be termed 

 a gigantic variety, but the impressed strise are more numerous, 

 and closer together. The form of the aperture is very near 

 that of R. inornata Binney.'^ 



The general aspect of this shell reminds one of the Asiatic 

 group, to which II. resplendens Phil, and H, mtrinoides 

 Desh. belonir.

It appears not a little singular that many of the Helices of 

 the United States are but imperfectly understood, and that 

 much contrariety of opinion exists both there and in Europe 



* This species is well known and understood, but I rather doubt its identity 

 with H. hiornata Say.
