This shell seems to be between U. beadleianus Lea and U. chicka- 
sawhensis Lea, and bears some resemblance to U. chunii Lea. It is 
more triangular than U. beadleianus, and more solid, with a differ-

posteriorly than chickasawhensis, and it differs in being less heavy 
in the beaks and in the outline of the shell. 
One specimen was received many years ago from Mr. A. G, 
Wetherby, from Viilage Creek, Hardin Co., Texas, and many speci- 
mens, lately, from Mr. H. G. Askew, of Austin, Texas, who is an 
earnest worker in this family of shells, and in whose honor I name 
this shell.
