82 Report of the President 



early close, Mr. Anthony secured a large amount of fossil 

 mammal material and incidentally collected 130 bats, represent- 

 ing, in good series, most of the species known from the island. 



Mr. George K. Cherrie returned early in the year from his 

 work along the Paraguay River, undertaken in extension of the 

 work in that region by the Roosevelt Brazilian Expedition in 

 1913-1914, of which Mr. Cherrie was a member. Colonel 

 Roosevelt's strong interest in this region as a rich field for 

 ornithological investigation has been shown by his contribution 

 of financial aid for Mr. Cherrie's second visit, which was sup- 

 ported by Colonel Roosevelt and Mr. Cleveland H. Dodge. 

 While Mr. Cherrie devoted his time largely to the study of the 

 life-history of the striking bird life of the region, he also se- 

 cured 750 specimens of birds to supplement his previous collec- 

 tion, and also a number of mammals. 



The Crocker Land Expedition, under the direction of Mr. 

 Donald B. MacMillan, returned toward the close of the year 

 after an eventful sojourn of four years in Arctic America, 

 where zoological as well as geographical and geological inves- 

 tigations were successfully prosecuted, resulting in important 

 additions of both mammals and birds to the resources of the 

 Museum. 



The Museum's share of the mammals collected on the 

 Collins-Day Expedition to South America have been received, 

 numbering 147 specimens, which, in accordance with the terms 

 of agreement respecting the results of the expedition, have been 

 identified and reported upon by Mr. Wilfred H. Osgood of the 

 Field Museum. 



During the year the Brewster-Sanford Collection has been 

 enriched by the addition of some 1,500 bird skins, of which 

 about 1,000 were collected in the West Indies by Mr. Rollo H. 

 Beck, after completing his several years of successful work in 

 collecting pelagic birds along the coasts and islands of southern 

 South America. The island of Santo Domingo, where he col- 

 lected nearly 800 specimens and visited the high mountains of 

 the interior as well as the coast district, proved of special inter- 

 est, his collection containing several new forms, an account of 

 which was promptly published by Curator Chapman in the 

 current volume of the Museum Bulletin.
