236 LAND AND FRESH-WATER SHELLS OF N. A. [PART IV. 



aperture ovate, bluish and translucent within, acuminate below; col- 

 umella nearly straight. Some of the specimens are marked in the 

 Fig. 460a. centre of the body- whorl with two, very narrow, dark, ap- 

 proximate bands. 

 Habitat. — Catawba Eiver, near Morgantown, N. Carolina. 

 Length, "63 ; width, '34 of an inch. Length of aperture, 

 •3; width of aperture, -17 of an inch. 

 Observations. — This species is nearest related to G. proxima, Saj', 

 which inhabits the same river. It is, however, a wider, more in- 

 flated species than G. proxima. — Haldeman. 



123. G. iota, Anthony. 



Melanin iota, Anthony, Ann. Lye. Nat. Hist., vi, p, 86, t. 2, f. i, March, 1854. Brot, 

 List, p. 3G. BiNNEY, Check List, No. 153. 



Description. — Shell conical, smooth, greenish horn-colored; spire 

 acutely elevated; whorls about ten, lower ones convex, upper with 

 a strong carina below the middle ; sutures impressed ; aperture pyri- 

 form, small, within whitish; columella but little rounded, Fig. 4606. 

 not indented ; sinus very small. 



Habitat. ? 



Diameter, -25 (6 niillim.); length, -78 of an inch (20 mil- 

 lim.;. Length of aperture, -26 (7 millim. ); breadth of aper- 

 ture, '15 of an inch (4 millim.). 



Observations.— A beautiful, slender, graceful species, in form not 

 unlike M. percarinata, Con., and perangulata, Con., but differs from 

 both in coloring, in the want of a crenulated or beaded line on the 

 volutions, and in other respects. The upper whorls ai'e often ob- 

 scurely folded down to the carina on each, where they are arrested ; 

 below the carina the whorls shelve towards the suture, which thus 

 becomes situated in a deep furrow. It cannot be confounded with 

 M. elevata, Say, which has flat whorls, a dark epidermis, and a totally 

 different aperture. The columella of the present species is faintly 

 tinged with purple. I am not quite sure as to the habitat of this 

 species, but think it an Ohio shell. — Anthony. 



124. G. nigrocincta, Anthony. 



Melania nigrocincta, Anthony, Ann. N. Y. Lye. Nat. Hist., vi, p. 90, t.2, f. 8, March, 

 1851. Bkot, List, p. 36. Binney, Check L:8t . 



Description. — Shell conical, smooth, not much or acutely elevated ;
