 incurved. Dark horn or olive color, much banded. Coosa

Fig. 331 represents Hartmanii, Lea, the full grown of this species; it is 

 the largest of the genus. Some specimens are slightly striate. 



243. G mellea, Lea. Fig. 332. Conical, subfusiform, 

 smooth, rather thick ; spire conical, sharp-pointed, suture well
