banded ; spire regularly conical ; sutures linear ; whorls about six, flattened above ; 

 aperture rather small, rhomboidal, whitish and single-banded within ; outer lip sharp, 

 slightly sinuous ; columella slightly bent in and twisted.

Hab. — South Carolina, Prof. L. Vanuxem. 



My cabinet. 

 Diam. -24, Length -60 inch. 



Remarks. — Among the numerous mollusca brought from the South long since by 

 my friend the late Prof. Vanuxem, I found a single specimen of this species, which is 

 different from all others brought by him. I do not know from what part of South 

 Carolina it came, but probably from Spartanberg District, as many of his specimens 

 were from there. This is a small, very regularly formed species, in general outline 

 near to lativittatum, herein described, but totally different in the band, that species 

 having it broad and dark, while this is hair-like and pale. It is also more fusiform. 

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



Trypanostoma rostellatum. PL 39, fig 225. 



Testa striata, attenuate, subtenui, cornea, evittata ; spira elevate ; suturis valde impressis ; anfractibus 

 octonis, convexiusculis ; aperturS, parva, rliomboidea, intiis albida ; labro acuto, valde sinuoso ; colu- 

 mella incurva et valde contorta. 



Shell striate, attenuate, rather thin, horn-color, without bands ; spire raised ; 

 sutures very much impressed ; whorls eight, slightly convex ; aperture small, 

 rhomboidal, whitish within ; outer lip very sinuous ; columella bent in and very 

 much twisted. 



Operculum ovate, dark-brown, with the polar point near the base on the left. 

 Proc. Acad. Nat. Sci., 1862, p. 272. 



Hab. — Florence, Alabama, Rev. G. White. 



My cabinet and cabinets of Mr. White and Dr. Hartman. 

 Diam. -30, Length -88 inch. 



Remarks. — Quite a number of this species was among the shells sent to me by Mr. 



White, collected by him in the northern part of Alabama some years since. It was 



supposed to be a variety of Melania (Goniobasis) proxima, Say, but the form of the 



aperture is quite different, having an expanded outer lip. It is also larger, some 



specimens being nearly an inch long, and it has not a carina, but usually three strise, 



the middle one of which rises almost to a carina. In some specimens there is only a 



single stria, sometimes two, ordinarily three, and rarely four. Usually the upper 



stria is continued on the lower whorl, extending to the aperture, but rarely any 



of the others. The aperture is about two-sevenths the length of the shell. It 



is allied to Whitei, herein described, but is a smaller species and differs in color, strise 



and in the aperture.
