 parts pale cuinamon, heavily streaked with lighter cinnamon-buff 

 and blackish; individual hairs blackish at bases, then narrowly buff, 

 then broadly cinnamon, with subterminal band of buff, and tip of

 ears, and over nape darker brown, mixed with blackish; large area of 

 blackish brown on cheek, and a smaller, sharply marked, blackish 

 brown spot above eye; feet, limbs, and underparts pale cinnamon-buff. 

 Basal half of tail above concolor with back; distal half mixed gray 

 and white, bordered and tipped with clear white. The black tips 

 to the hairs of the back rapidly wear away and the pelage becomes 

 a uniform dull cinnamon, mixed with light buff. The distinctive 

 markings of the head become more obscure. Adult in fresh full winter 

 pelage: General color more grayish and buff, less cinnamon, than in

 of white and gray on body. General color of upperparts dark cream- 

 buff, heavily mixed with pale buff and blackish, giving a decided

 in the fresh postjuvenile pelage are more vinaceous or pinkish cin- 

 namon than the corresponding pelage of C. g. gunnisoni.
