28 NORTH AMERICAN FAUNA. [no. 19. 



RenuirJis. — The closest relationship of this red S({uirrel is (evidently 

 with Jiudsonicus of northern Alaska J A single specimen from Ya- 

 kutat Bay shows a decided tendency toward the northern form, ai>d 

 those from Cook Inlet are clearly referable to it. A more or less im- 

 perfect specimen from Inverness, British Columbia, indicates a possi- 

 ble interg-radation with Sciurns h. streatmn. There is ample material 

 demonstrating ])y skulls as well as by color that it has no very close 

 relationship to S. Vancouver ensis. My specimens oij)ettdmhs taken 

 early in June are in new summer pelage or in old winter pelage just 

 previous to or in process of change. The latter doubtless does not 

 fairly represent the winter pelage; but in making comparison with 

 eastern specimens, 1 have chosen those in a similar condition. 



About Lynn Canal and on the southwest side of White Pass I 

 found these red squirrels abundant. Several at Glacier had become 

 quite tame, and came every day to the cabin of one of the railroad 

 hands to be fed. They have all the vivacious energy, curiosity, and 

 vocal accomplishments of their Eastern cousins, and fully maintain 

 their reputation for rollicking- good nature and fearlessness,

 narrower and darker than in E. horealis; underparts pure w^hite; feet

^The hudsonicus of northern Alaska is here considered the same as that from 

 eastern Canada, l)ut will d<)ul)tless prove sejiaraljle when an abundance of material 

 in all pelages is available.
