In iuUlition to these characteristic species are a uumber of iutrusive forms uot sufficieutly

Hesperocichla meria.

No doubt there are a number of others along the southern border. 



The Rocky Mountain Goat (Aplocerus montanus) is numerous in the Alaskan Range near its 

 sonthern border, but as its habitat lies between two of the fanual areas it cannot be classed justly 

 with either. In this district, as will be noted, occurs a curious blending of the faunas of the 

 Canadian and Uudson Bay districts with those of the west coast and the extreme north. In out- 

 lining the fauna! areas here 1 have laid particular stress on the mammals and birds, but I may 

 mention the foct that each district, as outlined, has certain essentially characteristic species of 

 fishes ; some butterflies also occur only in certain areas. In the coast districts, no doubt, other 

 peculiar species of the lower forms of animal life will be found limited to or characteristic of the 

 faunal areas as I have defined them. ♦
