88. Grinnell on Alaskan Birds. 



[Birds of the 1908 Alexander Alaska Expedition, with a Note on the 

 Avifaunal Relationships of the Prince AVilliam Sound District. By 

 Joseph Grinnell. Univ. of California, Publ. in Zool., Vol. v. No. 12. 

 Berkeley, Cal, 1910.] 



The territory selected for exploration by Miss Alexander's 

 third expedition to Alaska (1908) was the Prince- William- 

 Sound Region, which lies at the head of the Gulf of Alaska. 

 Its fauna was previously little known. The ornithological 

 material collected during the expedition, besides the 

 naturalists' field note-books, comprised 500 bird-skins and ten 

 sets of eggs, which have been presented by Miss Alexander 

 to the Museum of Vertebrate Zoology of the University of 

 California. 



The birds observed and obtained during the expedition 

 are referred to 89 species, concerning which there are many 

 interesting field-notes. Canachites canadensis atratus and 

 Lagopus rupestris k ellogcB are described as two new sub- 

 species of Grouse, Ceryle alcyon caurina as a new subspecies 

 of Kingfisher, Passerella iliaca sinuosa as a new Finch, and 

 Penthestes rufescens vivax as a new Titmouse. 



As an appendix to the memoir we have a discussion on 

 the origin of the Avifauna of the district examined, with the 

 result that it appears to belong to two different life-zones — 

 the " Hudsonian " and the " Alpine-Arctic." The former 

 is practically coincident with the timbered area, which i.s 

 confined to a narrow tract bordering the sea-shore and 

 extending up the valleys; while the " Alpine- Arctic " or 

 treeless zone covers the tops of the mountains and the 

 interior land-mass.
