Hab. Cumberland Mountains, near Jasper, Tenn. Dr. Currey. 

 My Cabinet, and Cabinets of Dr. Currey and Mr. Edgar. 

 Diam. .54, Length .14 of an inch. 



Remarks. — Among many species of land shells which I owe to Dr. Currey's 

 kindness, were two individuals of this Carocolla, which does not appear to have 

 been before noticed. It has some resemblance to H. alternata, (Say,) 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 visible in the umbilicus, and are striate all over. 



Cyclostoma Cincinnatiense. Plate 6, Fig. 62. 



Testa elevato-conicd, Icevi, nitidd, diaphand, umbilicata; anfractibus senis; apice obtuso; labro margine 

 reflexo. 



Shell elevated in the form of a cone, smooth, shining, transparent, umbilicate ; whorls six ; apex obtuse ; 

 margin of the lip reflected. 



Hab. Vicinity of Cincinnati. T. G. Lea. 



My Cabinet, and Cabinet of T. G. Lea. 

 Diam. .13, Length .22 of an inch. 



Remarks. — A small species which has been sent to me several times by my 

 brother, who seems first to have observed it. It is about the size and nearly of 

 the colour of Paludina limosa, Say. It is found on wet earth and roots of trees, 

 on the margin of a small stream near Cincinnati.
