California. Specimens with much 



white in the axilla are apt to show 



traces of white elsewhere on the lower 



parts, as on the lower part of the 



throat and middle of the breast.

Scijtnis incarnsi (Towrisend) 

 Mearn's Chickaree. Winter pelage 

 similar to 5. d. californicns, but pal- 

 er and grayer above, with the dorsal 

 band a paler, more jellowish shade of 

 chestnut. Summer pelage probably 

 similar to that of 5. d. californicns, 

 but lighter above and with the lower 

 parts only faintly washed with cream 

 white, and the feet both front and 

 hind, very much paler ochraceous. 

 Only four specimens have been exam- 

 ined from Lower California, San Ped- 

 ro mountains, April and .Vlay, and 

 hence in worn winter coat. The feet 

 have begun to show the coloration of 

 the summer pelage and in one speci- 

 men this is well developed over the 

 anterior two-thirds of the ventral sur- 

 face. The hind feet are white with a 

 faint tinge of fulvous; the fore feet are 

 in change to strong buff. The fulvous 

 tints on the lower parts and particular- 

 ly on the inner surface of the fore 

 limbs shows that the affinities of this 

 form are with 5. d. ca/ifornicus rath- 

 er than with S. f. inogollonensis. In 

 other respects it is quite as near the 

 latter as the former, the general col- 

 oration of mogolloncnsis and califor- 

 nicns being often closely similar. 

 Sciurus inearnsi is separated from the 

 range of both californicus and mogol- 

 loncnsis by a wide interval of country, 

 where at the present time no repre- 

 sentative of either group exists, or ap- 

 parently can exist. It seems, there- 

 fore, proper to treat this form as a 

 fully seggregated species, there being 

 no possibility of its intergradation 

 with either of the northern affines, 

 which it still so closely resembles, be- 

 ing evidently a recent derivative of 

 the californicus stock, 



Sciurus fremonti (Aud. & Bach.) 

 Fremont's Chickaree. Winter pel- 

 age, Above gray with a broad, not 



sharply defined median band of pile 

 yelllowish rufous; the hairs of the me- 

 dian band are plumbous at the base, 

 broadly tipped with jellowish rufous 

 and ringed with black, with a general 

 gray effect, fort and hind limbs, in- 

 cluding upper surface of feet, like 

 sides of body; an obscure nearly ob- 

 solete dusky lateral line; below, gray- 

 ish white, rather profusly annulated 

 with dusky. Tail above with the cen- 

 tral hairs yellowish rusty, rather 

 brighter than the middle of the back, 

 varied with black, forming a distinct 

 lateral area; lateral hairs fulvous bas- 

 ally, subapically broadly banded with 

 black and tipped broadly with white; 

 terminal fifth or sixth black, slightly 

 fringed with white; below, gray or 

 pale gulvous gray centrally, with a 

 broad zone of black and a conspicuous 

 fringe of white; ears slightly tufted 

 with dusky. 



Summer pelage. Above nearly 

 uniform yellowish gray, varying ' in 

 different specimens to pale rufescent 

 gray; upper surface of feet ochraceous, 

 the fore feet, including fore arm, 

 brighter and stronger ochraceous than 

 the hind; a strong deep black lateral 

 line; ventral surface white or grayish 

 white: tail colored nearly as in winter, 

 but narrower, and edged more nar- 

 rowly with white. 



Geographic range. The moun- 

 tainous portions of Colorado reaching 

 the extreme southern border of Wy- 

 oming at Woods P. O. and Unitah 

 Mountains of Utah; also reaching the 

 southern boundary of Wyoming at 

 Fort Bridger. 



The type locality of 5. fremonti is 

 not definitely known. Audubon and 

 Bachman state in their original de- 

 scription of the species "We possess 

 no information in regard to this ani- 

 mal further than that it was obtained 

 on the Rocky Mountains " They fur- 

 ther say "The only specimen we have 

 seen was obtained by Col. Fremont; 

 it was procured on the Rocky Moun- 

 tains on his route by the South Pass 

 to California." Baird, evidently
