pp. 1-9) ; but Mr. Wilfred H. Osgood's ' Results of a Biological 

 Reconnoissance of the Yukon River Region' (N. Am. Fauna, 

 No. 19, October, 1900, pp. 145) is of special interest in this 

 connection, since he made collections in the Lynn Canal 

 and White Pass districts, not far to the northwestward of 

 Telegraph Creek, and from which he described a number 

 of new species and subspecies represented in the present 

 collections. 



In this connection I wish to express my great indebtedness 

 to Dr. A. K. Fisher, Acting Chief of the Biological Survey, 

 U. S. Department of Agriculture, for the loan of topotypes 

 of Mr. Osgood's species and other needed material for use in 

 the preparation of the present paper.

 tail; chest, flanks, and front of legs black; belly white; neck 

 dingy brownish gray, with a white median band in front from 

 the throat to the chest, well developed in some of the speci- 

 mens- and rather indistinct in others; head and face blackish 

 brown, like the back. The antlers in the older males are 

 strikingly large and fine, nearly equalling in size those of the 

 Wapiti Deer.
