NOTES ON CALIFORNIA ANIMALS. 



cier, high up on ]\rount Shasta. I learned nothing of its occurreucc in 

 the Mount Lassen region, although it is found in the higli Sierras, 

 farther south. It exists in moderate numbers in Xortheastern Califor- 

 nia and the adjoining i^ortion of Oregon. 



Family SCIUEIDiE. Squirrels. 



Aictomys flaviventer And. and Uacli. Hock;/ I\roH)itaiii ^fnrmot. 



This animal was met Avith only on the eastern slope of the Sierras 

 in Jjassen County, and in l)ut one particular ledge of rocks, where it 

 lived in large numbers. It has been taken at Fort Crook by Captain 

 Feilner, and as this locality is also on the eastern side of the mountains 

 it ai)pears that the species may be confined to that side as I learned 

 nothing of its occurrence elsewhere in Northern California. 



Tamias lateralis (Say). Say''8 Chipmunk. 



This handsome animal is an abundant resident of the pineries, to 

 which it is strictly limited. It is found from the lower border of the 

 coniferous belt as high up on t-he mountains as the timber extends, 

 and in certain portions of its range, as on the western slope of Mount 

 Lassen, literally swarms. It, like all other Chipmunks of the higher 

 pine forests, passes the severer iiart of the winter in complete hyber- 

 nation. 



Resident hunters about Mount Sliasta said that Chipmunks never 

 appeared in midwinter. Its large size and distinct stripes render it a 

 conspicuous species in its haunts ; while riding along the unfrequented 

 roads through the pines one may see it continually bobbing up from 

 behind some rock or prostrate tree trunk, often remaining so close as 

 to render distinct every movement of its bright eyes twitching with 

 nervous curiosity.
