Seton on the Mammals and Birds of Manitoba

Recent Lite/atztre.[Auk [.Jan. between Eagle and Circle and in the mountains west of Eagle near the sources of Mission Creek."In the early part of the summer of 1904 a trip was made into the Ogilvie Range northwest of Dawson, Yukon Territow, "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 eo6peration of Mr. Charles Sheldon of New York, who "most generously bore practically the entire expense of tim trip."In 1903 Mr. Osgood was aeeompanicd by Mr. N. ttollister, and in 1906 by Mr. Charles Shddon and Mr. Carl Rungius.The report is divided into three parts, each treating of a (listinet area; the three areas, however, are contiguous and biologically, as welt as geographically, etosety related.The physiographic and biological features of each are described, followed by extensively annotated lists of the mmnmals and birds observe or collected in each area.Three maps indicate the routes traveled, and the geographic relations of the localities visited.The fore' half-tone plates consist of eight illustrations, from photog'aphs, 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 "Maenitlan Region" (pp.84-92), 55 spedes.In preparing the Alaska list Mr. Osgood utilized Mr. N. Hollister'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 Solira W Sandpiper, and a description of its newly hatched young.The 'Ogitvie 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 unknown biologically.It is to be noted, however, that a munber 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 occm' in the areas here considered.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.
