folds. It is allied to Melania {Goniohasis) Deshayesiana (nobis), but 

 is a smaller species. Its chestnut-brown color reminds one of Melania 

 (Goniohasis) castnnea (nobis), but it is not so elongate and is thicker. 

 The aperture is more than one-third the length of the shell. — Lea.

Description. — Shell folded, subcylindrical, dark horn-color or some- 

 v/hat ash-gray, thin, •without bands; spire drawn out; sutures irreg- 

 ularly impressed ; whorls about nine, slightly convex ; aperture small, 

 ovatelv rhomboidal, whitish within; outer lip acute, sinuous; 

 columella very much bent in, impressed in the middle and 

 very much twisted. 



Habitat. — Tennessee, Pi'of. Troost; near Vienna, Dooly 

 County, Georgia, in a small stream tributary to Flint River; 

 Rev. George White. 



Diameter, -32; length, -91 of an inch. 



Observations. — I have a number of specimens from Mr. 

 White, and one a long time since from Pi'of. Troost. It belongs to 

 the group of which Melania {Goniohasis) costnlata (nobis) may be 

 considered the type, but it is more cylindrical and has more distant 

 folds. It is also allied to Melania (Goniohasis) decora (nobis), but 

 is more cylindrical, has more distant folds and has no cancellate 

 stria;. The folds are curved and incline slightly to the left. The 

 aperture is not quite one-third the length of the shell. Some speci- 

 mens are disposed to be slightly brownish inside. — Lea. 



Goniohasis induta. — Shell very much folded, conical, rather thin, 



polished, dark, four-banded ; spire conoidal, sharp-pointed ;

sutures very much impressed; whorls eight, flattened, clothed 



with erect folds; aperture small, rhomboidal, whitish and 



four-lianded within ; outer lip acute, sinuous ; columella bent 



in and twisted. 



Operculum ovate, thin, light brown, with the polar point 



well inside of the margin. 

 Habitat. — Near Vienna, Dooly County, Georgia; llev. G. White. 

 Diameter, -31; length, -70 of an inch.
