334 NEW MELANID^ OF THE UNITED STATES. 



whorls are carinate, and a small thread-like line below runs parallel with the more 

 raised one. The two obscure bands are near to each other and are in the middle of 

 the whorl. In outline it is near to Melania {Goniobasis) nigrina (nobis), but it is a 

 larger species with a less polished surface and of a very much lighter color. It differs 

 entirely in being carinate. In both these specimens the whorls are slightly de- 

 pressed below the suture, which modifies the outer lip. One of the specimens has an 

 obscure brownish spot inside at the base of the columella. The aperture is about two- 

 sevenths the length of the shell.

 oso ; columella iucurva, aliquanto contorta.

Bernard. — This is a very small species, nearly allied to Melania ( Goniobasis) proximo,, 

 Say, but may be distinguished by its smaller size, its lighter color, its shorter spire, 

 and its having a raised line above and below the carina on the upper whorls. The 

 aperture is rather more than one-third the length of the shell. 



Goniobasis inosculata. PI. 38, fig. 195. 



Testa cariuata, eonoidea, subtenui, luteo-cornea, evittata ; spira subelevata ; suturis inipressis ; anfractibus 

 instar septenis, convesiusculis ; apertura submagna, rliomboidea, intus albida ; labro acuto, sinuoso ; 

 columella subincurva, inferne incrassata. 



Shell carinate, conical, rather thin, yellowish horn-color, without bands; spire 

 somewhat raised ; sutures impressed ; whorls about seven, a little convex ; aperture 

 rather large, rhomboidal, whitish within ; outer lip acute, sinuous ; columella some- 

 what bent in and thickened below. 



Operculum subrotund, thin, light brown, with the polar point on the left near the 



edge.
