Diam. .54, length .14 inch. 



Remarhs. — Among many species of land shells which I owe to Dr. 

 Currey's kindness, were two individuals of this Caracolla which does not 

 appear to have been before noticed. It has some resemblance to H. 

 alternaia Saj^, but may at once be distinguished by its depressed, flat, 

 lenticular form and carina. It is a very interesting species, and has a 

 remarkable furrow above and below the carina; all the whorls are visi- 

 ble in the umbilicus, and are striate all over. 



This beautiful species was extremely rare, even in American 

 cabinets, until Bishop Elliott, after diligent search during seve- 

 ral summers, discovered it in August, 1860, inhabiting a single 

 spur of the Cumberland Mountains, near University Place, 

 Franklin County, Tenn. In one of his letters to me he men- 

 tions having found it on the ground, under stones and wood, in 

 company with II. spinosa Lea, and also after rain creeping 

 upon precipitous faces of rock, with a few //. alternata (the 

 common Southern form), and Helicina orhiculata Say. My 

 largest specimen measures, Diam. maj. IT, min. 15, Alt. 5J
