Notes on American Land Shells. No. 3. 



BY W. G. BINNEY. 



The following species of Helicidae, now first described, were collected by Dr. 

 F. V. Hayden, of the Yellowstone Ex. Ex., (Lieut. G. K. Warren), Dr. T. S. 

 Newberry, of the Colorado R. Ex. Ex., (Lieut. Ives), Mr. Robert Kenicott, during 

 a recent visit to the Red River of the North, and in Mexico by the late Mr. Ber- 

 landiere, whose valuable collections were bought and presented to the Smith- 

 sonian Institute by Lieut. Couch. Specimens of all the species are deposited 

 in the collection of that Institution, and also in that of the Academy, through 

 the kindness of Prof. Baird, and the gentlemen named above. Figures of these, 

 and all species described by me, will be published at some subsequent time.
