Anantehely Mountains, North Carolina, Eastern Tennessee, Bridgeport, Ala. 

 It may be considered a species of the Cumberland Subregion. 



In sculi)ture it is closely allied to Z. indentatus, of which it might almost be 

 termed a gigantic variety, but the impressed striae are more numerous, and 

 closer together. The form of the aperture is very near that of Z. inornatus. 



The general aspect of this shell reminds one of the Asiatic group, to which 

 Helix resplendens, Phil, and //. vitrinoiJes, Desh. belong. 



Animal long, slender, dirty-white, bluish on head and eye-peduncles : a dis- 

 tinct locomotive disk, and furrows alongside of foot, meeting over a mucus 

 pore ; tail ' often recurved at tip, and bearing generally a drop of mucus on it ; 

 eye-peduncles long, slender. 



Jaw as usual in the genus. 



Z. sculptilis (PI. II. Fig. P) has 40 — 1 — 40 teeth on its lingual membrane, 

 with 4 perfect laterals. 



Genitalia unobserved. 



Zonites Elliotti, Kedfield. 



Shell with rather a narrow umbilicus, depressed-orbiculate, with fine trans- 

 verse striae, greenish horn-colored, hardly translucent, shining beneath ; spire

sometimes very slightly depressed at the aperture ; suture deeply 

 impressed ; aperture very oblique, lunate-circular ; peristome a lit- 

 tle sinuate, acute, but thickened within. Greater diameter 9, lesser 

 8 mill. ; height, 4 mill.

Mountains of Georgia and North Carolina, and AVayne County, West Vir- 

 ginia. It is a species of the Cumberland Subregion. 



Animal with a distinct caudal mucus pore, locomotive disk, and longitudinal
