 In the present paper Mr. Storer recommends a particular 

 form of pamphlet-case, open only at the back, which he lias 

 found the most practical, and he further gives a number of 

 liints for indexing and arranging which, if carried out, will 

 be found to render one's collection of friends' and corre-

In this short pamphlet Mr. Taverner reviews the history 

 and general relations of North American life to that of the 

 world in general, and then proceeds to delimit the faunal 

 zones of the Canadian Dominion, adapting for his purpose 

 the well-known classification of Dr. C. Hart Merriam. 

 The Zones repi-esented in Canada are : — (1) The Arctic — > 

 treeless and shrubless, with Snow-Buntings, Longspurs, 

 and Ptarmigan as characteristic birds; (2) The Hudsonian, 

 the region of small, stunted, mostly coniferous trees, with 

 the Rough-legged Hawk, Northern Shrike, and Pine Gros- 

 beak as characteristic birds ; (3) The Canadian zone, with 

 heavy coniferous forest and occupying the greater part of 

 the Dominion, with the Olive-backed Thrush, Three-toed 

 Woodpecker, Canadian Jay, and numerous (American) 

 Warblers ; (4) The Transition zone, consisting of prairies 

 and hardwood forests, with Wild Turkey, Bob-white, and 

 W^ood-Thrush as characteristic birds ; and finally (5) The 

 Upper Austral, a narrow belt of country along the northern 

 shores of Lakes Erie and Ontario, where the Mocking-bird, 

 Carolina AVren^ and Orchard Oriole are to be found,
