REPORT ON THE MAMMALS AND BIRDS OF THE EXPEDITION. 



By C. H. Merriam. 



Sir : T take pleasure in presenting my report on the mammals and 

 birds collected during the past season for publication in your report. 



I desire to tender my thanks to Mr. S. W. Jaycox for his assistance 

 in the collections. I collected, from the 5th to the 21st of June, oue 

 hundred and twenty bird-skins, and fifty-two nests with eggs. 



I wish to express my indebtedness to Mr. Piatt, whose collections in 

 my department would have been larger had he not also had charge of 

 the alcoholic and botanical collections made by that branch of the expe- 

 dition under your immediate control. I wish also to state that I am 

 nnder great obligations to Professor S. F. Baird and Mr. Eobert Ridg- 

 way, of the Smithsonian Institution, for aiding me in various ways. 



The total number of bird-skins collected is three hundred and thirteen ; 

 of nests, with eggs,, sixty-seven. I found no birds at Teton or Fire- 

 Hole Basins specifically diifereut from those collected at other places on 

 our route. 



I remain, yours, very resnectfully, 



C. HART MEREIAM. 



Dr. F. V. Hayden, 



United States Geologist.
