 Zapus trinotatus alleni. 



Zapus t. alleni Elliot, Field Columb. Mus., 1898, p. 212. 

 Zoology. 



1 Specimen, from Hot Springs, Long Canon, Mt. Whitney. 



This was the only example of Zapus procured on the journey, 

 and was taken at an altitude of 8,000 feet. It was apparently 

 very rare in the southern Sierras.

 ERETHIZON. 

 Erethizon epixanthus.

1 Specimen, Whitney Creek, Mt. Whitney. 



"In the High Sierras, near Mount Whitney, many of the lodge- 

 pole pines, Pinus murrayana, bear the characteristic scars due 

 to the gnawing of the porcupine; but, notwithstanding the 

 abundance of such signs, the animal is rare, and unknown to 

 many of the cattlemen. Their food consists, apparently, largely 

 of the bark of this pine, no other tree in the vicinity showing 

 the scars. Their range corresponds fairly well with that of the 

 lodge-pole pine, the scars occurring at all altitudes between 8,000 

 and 10,000 feet. The bark is usually gnawed at the base of the 

 tree, on one side only, or just above the larger limbs, which are 

 used as a resting-place by the animal as it works. On trees 

 where the limbs are placed at convenient intervals, the bark is 

 stripped for several feet,- the strip usually having a width of 

 five or six inches."
