LAND SHELLS. 
BY HENRY HEMPHILL. 
(1.) Patula strigosa Gld. var. subcarinata. 
The shell in general form resembles a large coarse elevated or 
depressed Cooperi. It has six whorls, well rounded above and 
beneath, and subearinated at the periphery. The body whorl has 
two revolving dark bands, one above and the other below the 
periphery ; sometimes the upper band spreads over the shell to the 
suture forming a dark chestnut zone that fades out as it passes 
toward the apex. The lip is simple, thickened, its terminations 
joined by a callus; aperture obliquely subangulate; the suture is 
well impressed. 
Height of the largest specimen 1 inch, breadth 12 inch. 
Height of the smallest specimen } inch, breadth 1 inch. 
Habitat, Rathdrum, Idaho. 
(2.) Patula strigosa Gld. var. bicolor. 
This shell is a colored variety of the above. 
It may be characterized as being of a general dark horn color 
mingled with dirty white; there are occasional zones of dark horn 
color above and fine dark lines beneath, but no defined bands. In 
some of the specimens the light color prevails, in others the horn 
color spreads over the shell in irregular patches. 
Height ¢ inch, breadth 1% inch.
