Habitat. — ^The mountains in Cherokee Co., JST.Car., D. Christy ! 



Remarks. — ^This interesting species is in form and size most 

 like a small variety of H. Mitchelliana Lea, or, the parietal 

 tooth considered, an imperforate specimen of H. hucculenta 

 Gould, but is especially distinct from both in its rufous color, 

 granulated and hirsute surface, and excavated umbilical region. 



This is the only known hirsute member, found east of the 

 Eocky Mountains, of the sub-genus Patera Albers. H. labiosa 

 Gould, which inhabits Oregon, is the only hirsute representative 

 of that sub-genus on the western side of the mountains. 



I am indebted to Mr. David Christy of Cincinnati for this 

 and the preceding, and also specimens of other somewhat rare 

 species found in the same region, viz. H. barhigera Redf. ; H. 

 Elliotti Redf. ; H. Clarkii Lea, &c. 



I dedicate this species to my esteemed friend Mr. C. M. 

 Wheatley, author of the first general catalogue of the Shells of 

 the United States, a zealous Naturalist, and generous contribu- 

 tor to the cabinets of others.
