REPORT ON THE MMIALS. AND BIRDS OF THE EXPEDITION. 



By C. H. Merriam. 



Sir : I take pleasure in presenting my report on tbe mammals and 

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



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

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

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



I wish to express my indebtedness to Mr. Piatt, whose coilection>9 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 

 nuder- 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 different from those collected at other places on 

 our route. 



I remain, vours, very resoectfully, 



C. HAET MEERIAM.
