GONIOBASIS. 313 



cord-like, making Avell impressed sulcations. This species reminds 

 one of Melania (Goniobasis) Vanuxemiana and ovalis (nobis), but it 

 is a more fusiform sliell, and has a longer aperture. Some of the 

 young are almost free from striaj, and are disposed to be plicate at 

 the apex. — Lea. 



Differs from Haysiana in the form of the aperture.

 1863. Obs., ix, p. 57. 



Description. — Shell much striate, reddish, subfusiform : spire sub- 

 elevated, conical ; sutures impressed; whorls about six, slightly con- 

 vex ; aperture rather constricted, elongate elliptical, reddish Fi^. G02. 

 within, obtusely angular at the base ; outer lip acute ; colu- 

 mella thickened, i-eddish, incurved. 



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



Diameter, •43 ; length, -90 of an inch. 



Observations. — There are five specimens before me, two 

 of them being old and so much eroded as to leave little more 

 than the body-whorl. The other specimens are more perfect, but the 

 apices are worn and their character unascertained. The species is 

 allied to Melania {Goniobasis) Haysiana (nobis), but may be distin- 

 guished by its not being cylindrical and by the aperture being longer. 

 Like Haysiana, the striaj are coarse and rounded, somewhat cord- 

 like. These striae number eight to ten. As Haysiana is sometimes 

 found without stria3, this species may also be found without them. 

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