 Diam. -35, Length -68 inch. 



Remarks. — This species is very nearly allied to Melania ( Goniobasis) Vanuxemiana 

 (nobis), having coarse striae over the whole of the whorls. But it is smaller, rather more 

 elliptical, and has more striae, the number being about ten. These striae are rounded, 

 with an intervening groove, and cover the whole of the whorls. The bands are ob- 

 scure on the outside of both the specimens before me, but are well-defined inside. It 

 has some resemblance to Melania (Goniobasis) Coosaensis (nobis), but is a much 

 smaller species, and is more constricted in the whorls and in the aperture. The ap- 

 erture is nearly half the length of the shell.

 six, slightly convex ; aperture large, ovately rhomboidal, whitish or brown within ;

Remarks. — I have quite a number of this species. It is well marked, and not easily 

 confounded with any other I know. The interior of some specimens are dark-brown, 

 with a white thickened margin on the outer lip ; others are light-brown, inclining to 

 obscure bands, while about one-half of all are white. The apicial whorls are usually 

 carinate. The body whorl has generally two or three obscure transverse striae about 

 the periphery, below which, towards the base, they are closer and coarser. There 

 is a strong disposition in some specimens to a depression below the suture. The
