show a more or less strong fulvous wash on the lower parts, 

 especially over the pectoral and axillary regions, due to por- 

 tions of the summer coat still remaining, the moult into winter 

 dress not having been completed. 



The 14 November specimens from Kupreanof Island mea- 

 sure as follows: 8 males, total length, 312 (291325); tail 

 vertebrae, 122 (104-134); hind foot, 51 (49-52); ear, 24 (23- 

 26): 6 females, total length, 309.5 (296-321); tail vertebrae, 

 122 (115-127); hind foot, 50 (49-51); ear, 23 (22-24). 



These specimens appear to be distinctly referable to van- 

 couverensis, hardly differing in size or color from Vancouver 

 Island examples. 



7. Sciurus (Tamiasciurus) hudsonicus baileyi Allen. BAILEY 



CHICKAREE. 



Sciurus hudsonicus baileyi ALLEN, Bull. Am. Mus. Nat. Hist., X, 

 1898, 261. July 22, 1898. Bighorn Mountains, Wyoming; altitude, 

 8400 feet. 



Represented by 47 specimens taken at Telegraph Creek, 

 July 1 5 to August 15; 2 taken at the head of Shesley River, 

 September i and 6 ; 6 taken on Level Mountain, September 

 1319; and 2 on Raspberry Creek, Oct. 5 and 8; making 

 a total of 57 specimens. Greatly to my surprise, they appear 

 to be referable to S. h. baileyi, from Alberta specimens of 

 which they do not very appreciably differ. They are hence 

 quite different from 5. h. petulans Osgood, of which I have 

 several topotypes for comparison, being much paler and 

 grayer in post-breeding pelage, with the tail fringed with 

 yellowish white instead of deep yellow as in petulans. 



In this large series of specimens, practically all in sum- 

 mer pelage, there are several that depart greatly in coloration 

 from the average or normal phase, an adult male (No. 19874) 

 from Telegraph Creek, August 5, being as red, and of nearly 

 the same shade of red, as average August specimens of 5. h. 

 loquaoc taken in New York or New Jersey ; while a young male 

 (No. 19868), taken July 30, at the same locality, is also easily 

 matched by specimens of corresponding age from New York.
