PLEUROCERA. 131 



some years since by my deceased friend, Joseph Clark. They were 

 collected by Prof. Christy. There is great variety in the color of 

 these specimens. Some are entirely ferruginous, others have a single 

 light line under the sutures, others again have two well defined 

 rather broad brown bands. It is closely allied to Vanuxemii, herein 

 described, from South Carolina, but difl'ers in having a larger aperture 

 and a higher spire. The aperture is about one-third the length of the 

 shell. — Lea. 



The figure is a copy of that given by Mr. Lea.

Description. — Shell smooth, obtusely conical, rather thick, straw 

 color, without bands, sharp pointed; spire obtusely conical; sutui-es 

 impressed; whorls eight, somewhat convex; aperture rather small, 

 rhombic, pale straw color within ; outer lip sharp, sinuous, 

 thickened near the margin; columella bent in, thickened and 

 twisted below. 



Habitat.— South Carolina? Prof. L. Vanasem. 



Diameter, -34; length, -75 inch. 



Observations. — Two specimens of this pretty little species 

 were found among many shells long since given to me bj' mj' friend, 

 the late Prof. Vanuxem. It is allied to Vanuxemii (nobis), but may 

 at once be distinguished by being without bands, and being a larger 

 and yellow species. The aperture is rather more than one-third the 

 length of the shell.— ie«. 



Figured from Mr. Lea's plate. 



I cannot distinguish specifically the following : — 



Trypanostoma CaroUnense. — Shell smooth, conical, rather thick, 

 horn-color; spire obtusely conical; sutures impressed; whorls seven, 

 slightly convex; aperture rather small, rhomboidal, whitish or brown- 

 ish within; outer lip sharp, sinuous; columella bent in, thickened 

 and twisted. 



Habitat. — South Carolina; Prof. L. Vanuxem. 



Diameter, -34 ; length, -70 inch.
