GONIOBASIS. 325 



six, flattened above, the last inflated ; aperture large, yellowish or 

 purplish within ; outer lip sharp ; columella arcuate, thickened, ob- 

 tusely angular at base. 



Habitat. — Coosa River, at "Wetumpka and Montevallo, Bibb County, 

 Alabama; E. E. Showalter, M.D. 



Diameter, -40 ; length, -76 of an inch. 



Observations. — Six specimens are before me. Two of them are 

 mature, are yellowish and are somewhat thick. Four j,j„ ^^ 

 are thinner and are purplish inside and out, not disposed 

 to be banded, but are obscurely maculate. The apical 

 whorls have obscure folds. One of the old ones has ob- 

 scure bands on the inside. The other has none. The 

 aperture is more than half the length of the shell. It is 

 somewhat like Melania fuligiiwsa (nobis) in outline, but it is not so 

 much inflated as that species. — Lea.

Description. — Shell striate, fusiform, solid, yellow, banded; sutures 

 much impressed ; whorls six, rather convex ; aperture oval, narrow, 

 whitish within. 



Habitat. — Alabama. 

 Diameter, -40; length, -02 of an inch. 



Observations. — A number of specimens were kindly sent by Dr. 

 Fig. 626. Foreman for my inspection, several of which are young, 

 exhibiting on the flrst two or three whorls very distinct 

 folds. Those of the larger specimens are worn off. The 

 mature specimens are remarkable for their irregularly ellip- 

 tical form, generally having transverse striaj over the whole 

 surface. The aperture is very regularly ovate, fully the 

 half of the length of the shell.— Lea. 



This si^ecies is not so broadly ovate as G. laeta and is also 

 smaller.
