1184 Life-histories of Northern Animals 



sienna, but on the upper part and across the breast each hair 

 has a dark orange-brown or sienna outer part that gives the 

 general colour, with the pale under-fur showing through at 

 places; finally, each hair on the fore-back and across the chest 

 has a silvery-white tip; on the shoulder in front of their wings 

 these are so large as to form a white spot on each side. In 

 certain lights the back fur has the efi^ect of rich golden-brown 

 glossed with purple. Individuals vary from yellow to deep 

 red, but the style is unmistakable; by its colour alone the Red- 

 bat may be known. 



In the air, its long, thin wings distinguish it from all but 

 the Hoary-bat; the probabilities of time and place, as well as 

 their sizes, will help in discriminating these two. 



The following races are recognized: 



borealis Miiller, the typical form. 



seminolus Rhoads, darker (mahogany brown). 



pfeifjeri Gundlach, larger and deeper coloured than 



borealis. 

 teliotis H. Allen, smaller and deeper coloured than 



borealis, with tail-web furred only on basal third. 

 mexicanus Saussure, like teliotis, but membranes and 



feet less hairy. 



Life-history. 



Its range covers the continent from the southern edge of 

 the Hudsonian to the northern edge of the Tropical fauna, 

 east of the Great Plains, as set forth on Map No. 67, and yet 

 farther into Central or South America. Its claim to be in 

 the Manitoban list rests on 3 specimens, i I received from 

 Morden, where it was captured by D. Nicholson, and 2 

 taken at Winnipeg and shown to me by Edward Wilson. 

 Another was taken by Edwin Hollis at Touchwood Hills, 

 September 16, 1901; it was a female. G. F. Dippie assures 

 me that he has taken it several times at Calgary, Aha.
