MAP ILLUSTRATING FAUNAL ZONES OF NORTH AMERICA. 



Through the courtesy of Dr. H. W. Henshavv, Chief of the Biological 

 Survey of the United States Department of Agriculture, we are enabled to 

 publishthe Fourth Provisional Zone Map of North America. This map 

 has not yet been published by the Biological Survey, by whom it was 

 prepared, to accompany a revised edition of their Bulletin No. 10, now in 

 course of preparation, but has appeared in the American Ornithologists' 

 Check List. 



Our object in publishing this map is primarily to assist those engaged 

 in the preparation of the Catalogue of the Insects of Canada and New- 

 foundland. (See pp. 273-275 of Vol. XLIII of this journal.) On page 

 274 it was stated that the geographical distribution of each species within 

 Canada and Newfoundland will be given. "This will be indicated as a 

 rule by Provinces, in order from east to west, e.g., N. S., Ont., B. C, etc. 

 The characteristic faunal zones inhabited by the species will be indicated 

 so far as it may be possible by abbreviations, thus : Ar.-Arctic, H.- 

 Hudsonian, C. -Canadian, T.-Transitional " With the addition of Upper 

 Austral, to be indicated by '"U. A.", these are all the zones which are 

 represented in Canada and Newfoundland, so far as we know at present. 

 The entire map of North America has been published, as it is impossible 

 to consider or discuss the faunal zones of Canada apart from those of the 

 United States. 



In stating the distribution of provinces, the recent extensions made to 

 the boundaries of the Provinces of Manitoba, Ontario and Quebec should 

 be noted. The northern boundary of Manitoba is marked by the 60th 

 parallel, and the new north- eastern- boundary is a line drawn from the 

 north-eastern corner of the original boundaries to the shore of the Hudson 

 Bay, where the latter is intersected by the 89th meridian. The Province 

 of Ontario extends northward to the Hudson Bay, east of the eastern 

 boundary of Manitoba. The Province of Quebec extends northwards, 

 and includes the region of Ungava.

 careful study of faunas of western North America, in a recent letter to me,
