OF CONCHOLOGY. 31 



138. G. COngesta, Conr. Subulate; wliorls 9, the lower 

 ones obscurely angulated, those of the spire acutely carinate 

 towards the apex ; suture well defined ; body whorl obscurely 

 sub-angulated ; aperture longitudinal, elliptical. 



The above is Conrad's description. The shell has never been figured, 

 and I cannot find any specimens named in any of our collections. 



g. Short, clavate, smooth species. 



139. G. auriculseformis, Lea. Fig. 191. Elliptical, smooth, 

 rather thin ; spire short, suture impressed ; whorls 0, slightly 

 convex, the last large ; aperture elongate, contracted. Yellow, 

 whitish within. Tuscaloosa, Ala. 



140. G. Nickliniana, Lea. Fig. 192. Obtusely conical, 

 smooth, solid; spire short, suture impressed; whorls 6, slight- 

 ly convex ; aperture large, somewhat rounded. Very dark 

 horn-color, purple within. Bath Co., W. Va. 



141. G. aterina, Lea. Fig. 193. Sub-fusiform, smooth, 

 solid; spire obtusely conical, suture impressed; whorls 6, con- 

 vex ; aperture large, sub-ovate, columella inflected, .thickened 

 and contorted. Black or greenish-black, purple within. E. 

 Tenn. 



Smaller and narrower than No. 140, and more angulate on the periphery. 



142. G. Binneyana, Lea. Fig. 194. Obtusely fusiform, 

 smooth, rather thin, very much inflated; spire depressed, coni- 

 cal, suture impressed ; whorls 5, slopingly flattened above, the 

 last ventricose; aperture very large, sub-ovate; columella 

 thickened, spotted at the base. Dark olive, obscurely banded, 

 dark purple within. Coosa River, Ala. 



More oval, with less expanded lip than No. 140. 



143. G. ebenum, Lea. Figs. 195, 196. Obtusely conical, 

 smooth, thick ; spire obtuse, suture slight; whorls 4 (trunca- 

 ted), somewhat flatly convex, the last with a rounded angle at 

 periphery; aperture large, ovate, sub-angular at base. Very 

 dark purple or blackish, purple or bluish within. Robinson 

 Co., Tenn. 



144. G. Vauxiana, Lea. Fig. 197. Fusiform, smooth, 

 rather thin; spire very obtusely conical, suture lightly im- 

 pressed; whorls 5, flattened above, and somewhat sub-carinate 

 at apex, the last one inflated; aperture very large, widely 

 rhomboidal, angular at base. Green. Coosa River, Ala. 



145. G, larvseformis, Lea. Fig. 197a. Obtusely fusi- 

 form, smooth ; whorls 6 — 7, the first few minutely keeled ; 

 aperture ovate. Olive. United States. 



The above species, described by Mr. Reeve, I have not seen ; but, judging 

 from the figure, it must be very close to, if not identical with G. Vauxiana, 

 Lea.
