256. G. virgulata, Lea. Figs. 350, 351. Ovate, thick, 



smooth ; spire short conical, suture much impressed ; whorls 7, 

 convex, the last large, inflated ; aperture diagonal, long, and 

 narrow, angular at base. Greenish -yellow, four-banded. Coosa 

 River ^ Ala. 



Fig. 351 represents O. glandarm, Lea, the adult. In the young shell the 

 spire, when present (Fig. 350J, is attenuate and sharp-pointed. 



257. G. clara, A7ith. . Fig. 352. Ovate, smooth, thick ; 

 spire conical, suture slightly impressed ; whorls 7, flat, the last 

 large, inflated ; aperture ovate, angulate at base. Yellow, with 

 four brown bands. Ala. 



258. G. inflata, ITald. Fig. 353. Ovate-conical, smooth, 

 thick; spire ccniica], suture moderately impressed; whorls 5, 

 flattened, the last inflated; aperture rhomboidal, angulate at 

 base. Brown or green, banded inside with red. Alabama 

 River. 



The above description does not correspond altogether with that of ger- 

 mana, Anth., but if the figure here given (which is copied from Reeve's 

 '' Conchologia Iconica," and represents a shell in Mus. AnthonyJ is inflata, 

 then the two are probably identical. 



259. G. fusiformis, Lea. Fig. 354. Fusiform, smooth, 

 rather thin ; spire short-conical, acute, suture linear ; whorls 6, 

 the last inflated ; aperture ovate, rounded below. Yellowish, 

 sometimes double-banded. Tenn. 



260. G. bellula. Lea. Fig. 355. Subfusiform, striate, 

 someahat thick ; spire short, suture well impressed ; whorls 5, 

 convex, the last large ; aperture rather large, elliptical, obtuse- 

 ly angular at base. Pale horn color, four-banded, white and 

 banded within. Ydlowleaf Qreek, Ala. 



261. G. calculoides, Lea. Fig. 356. Subfusiform, robust, 

 irregularly striate, and noduled above; spire obtusely conical, 

 suture irregularly impressed; whorls 6, much inflated, the last 

 large; aperture rather small, elliptical, angled at base, colu- 

 mella perpendicular, straight. Plorn color, with or without 

 bands. Coosa River, Ala. 



262. G. basalis, Xea. Elliptical, thick, smooth ; spire 

 short, obtuse, suture impressed ; whorls convex ; aperture 

 ovately elongate, acutel}' angular at base. Yellowish-green, 

 banded. Ala. 



Resembles 0. glandaria, Lea, but is thinner, the outer lip more expanded, 

 and the aperture rather longer. It is closely allied to O. fusiformis, Lea. 



263. G. Lewisii, Lea. Fig. 357. Somewhat cylindrical, 

 thick, coarsely striate; spire raised conical, suture much im- 

 pressed; whorls 6, flattened, with rough revolving ridges or 

 strioe ; aperture small, ovately rhomboidal, obtusely angular at 

 base. Dark green, four-banded Coosa and Tallapoosa Rivers,
