between Eagle and Circle and in the mountains west of Eagle near the 

 sources.of Mission Creek." In the early part of the siimmer of 1904 a trip 

 was made into the Ogilvie Range northwest of Dawson, Yukon Territory, 

 "to supplement the work done in 1903 in the mountains lying on the 

 opposite side of the Yukon River, in Alaska." The trip to this latter region 

 involved considerable expense, and for this reason had been necessarily 

 deferred. In 1904 it was made possible through the cooperation of Mr. 

 Charles Sheldon of New York, who "most generously bore practically the 

 entire expense of the trip." In 1903 Mr. Osgood was accompanied by Mr. 

 N. Hollister, and in 1906 by Mr. Charles Sheldon and Mr. Carl Rungius. 



The report is divided into three parts, each treating of a distinct area; 

 the three areas, however, are contiguous and biologically, as well as geo- 

 graphically, closely related. The physiographic and biological features 

 of each are described, followed by extensively annotated lists of the mam- 

 mals and birds observe or collected in each area. Three maps indicate the 

 routes traveled, and the geographic relations of the localities visited. The 

 four half-tone plates consist of eight illustrations, from photographs, of as 

 many characteristic localities in the areas visited. 



The ornithological observations are given, as already stated, in the 

 form of annotated lists of the species met with. The ' Birds of East Central 

 Alaska' (pp. 33-44) number 76 species; those of the "Ogilvie Range" 

 list (pp. 58-65), 43 species; those of the "Macmillan Region" (pp. 84-92), 

 55 species. In preparing the Alaska list Mr. Osgood utilized Mr. N. Hol- 

 lister's notes, and had opportunity also to examine specimens of some 25 

 additional species obtained by other collectors in this region, as mentioned 

 in the introductory paragraph to this list, which contains extended notes 

 on the habits of the Western Solitary Sandpiper, and a description of its 

 newly hatched young. The 'Ogilvie Range' and 'Macmillan River' lists, 

 though numbering fewer species, include several not recorded in the ' East 

 Central Alaska' list. The observations here placed on record add greatly 

 to our knowledge of the ranges and relative abundance of the birds and 

 mammals of these regions, which were to a large extent previously un- 

 known biologically. It is to be noted, however, that a number of species 

 of both birds and mammals are formally included in the lists that were 

 neither collected nor observed, but simply for the reason that from their 

 known distribution they undoubtedly must occur in the areas here con- 

 sidered. While incidental mention of such species is desirable, it is hardly 

 consistent with modern methods to include them in a formal manner 

 with species "collected or observed." — J. A. A.
