2GG LAND AND FRESn-WATER SHELLS OF N. A. [pART IV. 



bands, -while about one-half of all are white. The apical whorls are 

 usually cariuate. The body-whorl has generally two or three ob- 

 scure, transverse stria; about the periphery, below which, towards 

 the base, they are closer and coarser. Tliere is a strong disposition 

 in some specimens to a depression below the suture. The aperture is 

 about three-eighths the length of the shell. I dedicate this to the 

 Right Ileverend Stephen Elliott, who has done so much to develop 

 the zoology of Georgia. — Lea.

Description. — Shell carinate, rather acutely conical, somewhat thin, 

 yellow ; spire somewhat elevated ; sutures impressed ; whorls nine, 

 rather convex; aperture small, ovate, angular at the base, within 

 whitish. 



Habitat. — Chester District, South Carolina. 

 Diameter, •34; length, -87 of an inch. 



Observations. — Many years since, I was not satisfied that it was not 

 merely a variety of semicarinata, Say, but I am disposed to think it 

 Fie 510 cliff^'i's too much to be considered merely a variety. It is a 

 larger shell, with more whorls and more distinct carinations. 

 The color also differs, in being much lightei*. A single speci- 

 men was among the shells sent from Major LeConte, which, 

 I suspect, is from Georgia, the locality not being certain. 

 Those from Professor Vauuxem are from Major Green's 

 farm. The aperture is less than one-third the length of the 

 shell. All the specimens are without bands but one, which has four, 

 large, distinct ones. — Lea.
