SiERRAx Collection. 



These specimens were all secured in June and July, 1898 on a trip 

 to Mount Tallac. Some specimens obtained to the east of the moun- 

 tains as well as a few from western Nevada, are included. 



Ammospermophilus leucurus (Merriam). 



July 18. Gardnerville, Nevada. Rather pinker than any of our 

 leucurus series, but the latter are all winter specimens, which i30ssibly 

 accounts for the difference in tint. 



Colobotis beldingi (Meniam). 



A series from Mount Tallac. 

 Citellus grammurus beeeheyi (Rich.). 



Two females. Mount Tallac, July 4 and 6. A silver suffusion ex- 

 tends across the central dark band on the hind neck and shoulders, 

 nearly obliterating it, thus tending toward fisheri. 

 Callospermophilus chrysodeirus (Merriam). 



A series from Mount Tallac shows great variation in the depth of 

 color on the head and shoulders, 

 Eutamias senex (Allen). 



A series from Mount Tallac, Several of the July siDCcimens show

Six specimens. Mount Tallac and Mount Sugar. One taken July 17 

 is bright rusty red on the sides and more red above, being well ad- 

 vanced in the molt to the post-breeding pelage.
