trapezoidal; columella iucurved. 



Habitat. — Holston Eiver, East Tennessee. 



Diameter, -30 ; length, -70 of an inch. 



Observations. — The four specimens before me have each 

 three bands, which with the yellowish tint below the 

 sutures give the shell a lively appearance. The superior 

 whorls are disposed to be bicarinate, and the lower carina 

 being covered with the whorl below, causes a furrow along the suture. 

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

 at the base, with rather a large sinus. — Lea. 



The figure is copied from Reeve. 



Mr. Anthony has placed specimens in my cabinet with the 

 habitat Alabama, affixed.

Description. — Shell carinate, acutely conical, rather thin, yellow,

 tened; aperture small, ovate, angular at the base, white

within. 

 Habitat. — Alabama. 

 Diameter, -33 ; length, 'OG of an inch. 



Observations. — A single specimen only was submitted to 

 rae, and this not very perfect. It is a peculiar shell in its 

 general appearance, the color being of an unusually bright 

 yellow, with two broad, distinct bauds, one immediately above 

 the middle of the whorl, and the other below. The superior part of 

 the whorl is darker than that below. The number of whorls cannot 

 be given, the apex being broken. There were probablj' nine or ten. 

 The aperture is about one quarter the length of the shell. — Lea.
