GONIOBASIS. 173 



Operculum ovate, thin, light brown, with the polar point well re- 

 moved from the left margin and the base. 



Habitat. — Twenty-one miles north of Murphy, and other places in 

 Cherokee County, N. C. ; Prof. David Christy. 



Diameter, '32 ; length, -Gl of an inch. 



Observations. — I have a uunil)er of these from several habitats in 

 Cherokee County, North Carolina. From the different habitats there 

 is a great variety of character, about half seem to be plicate, 

 the others perfectly smooth ; the folds not being on the upper 

 whorls, but commencing on the body-whorls or the penulti- 

 mate, and these folds are on the shoulder, and somewhat 

 curved and close. Some are lighter green and white inside 

 being without bands. The bands are usually four in number, 

 with the two middle ones approximate. The smooth, green, elongate 

 varieties look very much like 3Ielania (Goniobasis) Saffordii (nobis), 

 but it cannot be confounded with that species. The dark banded 

 varieties might be mistaken for the Melanin (Goniobasis) suhangulata, 

 Anth. The aperture is about half the length of the shell. — Lea.

aperture large, ovatcly rhomboidal ; whitish within ; outer lip 



acute, scarcely sinuous; columella slightly bent in and 

 twisted. 



Habitat. — Florence, Alabama; Rev. G. White. 

 Diameter, -30; length, -02 of an inch. 

 Observations. — A single specimen only was found among the numer- 

 ous shells kindly sent to me some years since by Mr. White. The 

 folds arc rather close, well-delhied, and incline to the left, reaching 

 liair way down the body-wliorl, and are crossed by transverse stria;, 

 which cover the whole surface, and cause the upper portion to be 

 clathrate. The aperture is nearly half the length of the shell. — Lea. 



More convex than vassuJa, Con., with more regular striae, 

 and ii altogether a handsomer species.
