this country is thus very greatly increased. The complete report on 

 the collection has not yet been published, but two preliminary papers 

 have appeared describing one genus and twenty-eight species and 

 subspecies of mammals new to science which are contained in the col- 

 lection. Several short expeditions for local field work were undertaken 

 with successful results. Mr. Osgood spent two weeks in August in 

 northern Wisconsin and a few days in northwestern Illinois collecting 

 small mammals. 11 1 specimens were secured. Later, in November, 

 through the kindness of Mr. Cyrus H. McCormick, Mr. Osgood spent 

 two days at White Deer Lake, near Champion, Michigan, making 

 photographs and preliminary arrangements for securing material for 

 a group of beavers. Mr. C. A. Corwin, artist, and Mr. Julius Friesser, 

 taxidermist, spent ten days in July at East Tawas, Michigan, securing 

 material for preparing bird groups. Mr. Corwin later spent several 

 days at Dowagiac, Michigan, and a week in the vicinity of Yule, North 

 Dakota, making sketches and color notes for use in background work. 

 In October, L. L. Pray, taxidermist, spent two weeks at Dowagiac, 

 Michigan, securing material for the preparation of groups of small 

 mammals. The services of Mr. Henry F. Raven, of Venezuela, were 

 secured for six months' work in Costa Rica and Venezuela as collector 

 of mammals and birds.
