Cioneila (Zua) ^^^orseana, Doherty. (Plate IV., fig. 2.) 



Shell cylindrical, slender, thin, transparent, highly polished, 

 reddish-brown, -with slight, irregular lines cf growth ; -whorls 5}.4, 

 flattened, the last nearly one-third the length ; suture little im- 

 pressed; apex very obtuse; aperture oblong-ovate, widest near 

 base ; p:ristoiiii scarcely thickened, reddish ; unihilicus closed ; 

 columella perpendicular, meeting base of peristome at something 

 less than a right angle. 



Fojt while, almost translucent ; Jiead grayish, with short 

 tentacles. 



Length 7 mill., sometimes more; diam. 2 mill. Aperture 

 2 mill. long. 



Found in beds of leaves in woods, Kenton County, Kentucky, 

 and Hamilton County, Ohio ; solitary, rare. 



It may be viviparous. In the winter it closes its shell with an 

 opaque, white epiphragm, like that of Helix profunda or H. 

 poinaiia. 



Differs in many respects from C. subeyliudrica, L. The 

 shell is longer,, more slender, more cylindrical, the Avhorls flatter, 

 the columella straighter, the apex and base more obtuse, the foot 

 lighter, the shell darker and less opaque. 



I take the liberty of naming this species after the distinguished 

 American naturalist, Prof. Edward Morse.
