322 LAND AXO FKESII-AVATER SHELLS OF N. A. [pART IV. 



transverse striae, which are rather sharp ; the two upper ones, being 

 rather distant, cause quite a large furrow between them. Other speci- 

 mens may not present these characters, as strias, whether fine or 

 coarse, vary very much on the 3Ielanidce. The color on the callus 

 of the columella may also vary in other individuals. The aperture 

 is nearly half the length of the shell. This species is allied to Vanux- 

 einiana (nobis), but it has not so high a spire, and it is wider in pro- 

 portion. — Lea. 



Goniohasis sitavis. — Shell smooth, subfusiform, rather thick, yel- 

 lowish-green, polished, four-banded; spire obtusely conical; sutures 

 regularly impressed ; whorls six, slightly flattened above ; aperture 

 Fig. 020. rather large, elliptical, whitish and banded within; outer lip 

 acute ; columella incurved and rounded at the base. 



Habitat. — Coosa River, Alabama; E. R. Showalter, M.D. 



Diameter, -SS ; length, -08 of an inch. 



Observations. — There are two specimens before me of this 

 pretty little species, both of the same size and appearance in every 

 way. The bands are remarkably perfect and well defined, and the 

 two middle ones, in these specimens, are approximate, while they arc 

 equidistant from that above and below. It reminds one of Melania 

 ovalis (nobis), but it has a higher spire and is more disposed to 

 be fusiform. The greenish-yellow tint, its well marked bands and 

 shining surface, give it a very agreeable aspect. — Lea.

 slightly callous above, obtusely angular at the base. 



Operculum ovate, spiral, light brown, with the polar point near the 

 edge towards the base.
