GOMIOBASIS. 285 



acquainted. It resembles some of the young varieties of 31. Virrjin- 

 ica, Saj', but has the whorls more convex, and the aperture smaller. 

 Four or five specimens are banded, and these have uniformly two 

 bands, the inferior one being larger and much more distinctly marked. 

 The first few whorls of the apex are cariuate. The aperture is about 

 one-fourth the length of the shell. — Lea. 



The figure given b}?- Reeve is perhaps the same as Haleiana, 

 but differs considerably.

Description. — Shell carinate, awl-shaped, rather thin, reddish, with- 

 out bands ; spire attenuate ; sutures very much Impressed ; whorls 

 eight, somewhat convex ; aperture very small, subrhomboidal, whit- 

 ish or reddish within ; outer lip acute, sinuous ; columella slightly 

 bent in and twisted. 



Habitat. — Near Murphy, Cherokee County, North Carolina; Prof. 

 Christy. 



Diameter, -23; length, -GS of an inch. 



Observations. — I have eight specimens before me, sent some years 

 since by my late friend, Mr. Clark, being part of the collection rig. 551. 

 made by Professor Christy. In form and size this species 

 is very near to Melania {Goniobasis) teres (nobis), but it 

 differs in being carinate, and having striae which in all the 

 specimens reach more than half way down from the apex. 

 Teres is not striate. In the aperture there is also a difference. The 

 aperture is about two-sevenths the length of the shell. — Lea.
