two skins, respectively, from Telegraph Creek, August 31, 

 and Shesley River. The Shesley River skin is much the 

 younger of the two, and in better pelage; the general colora- 

 tion is less dark, owing to the greater abundance of long hairs, 

 which are more broadly tipped with pale yellowish whittf. 



Compared with Dr. Merriam's description of E. epizanthus 

 my ops from the Alaska Peninsula, and with a very fine large 

 November specimen from Kenai Peninsula, the present form 

 differs strikingly in its very much darker coloration and the 

 much paler tips of the long hairs, which are pale yellow in- 

 stead of deep yellow. The skulls of porcupines differ so 

 greatly with age and individually, and the material for com- 

 parison is at present so scanty, that no very positive cranial 

 differences are apparent. The four skulls of the present series, 

 however, agree in possessing a very marked depression of the 

 top of the skull at the fronto-parietal region, and in the great 

 development of the lateral border of the interorbital region, 

 which, just behind the orbits, forms a high obtuse knob, thus 

 greatly emphasizing the fronto-parietal depression. In an 

 equal number of Alaska skulls referable to myops both these 

 features are practically absent. 



"Porcupines are not infrequent near Telegraph Creek, 

 though we took but one specimen." The same report is 

 made for the camps at the head of Shesley River and Table 

 Mountain.

Two adult specimens, male and female, Telegraph Creek, 

 October 20 and 21. Both are in change from summer to 

 winter pelage, the female retaining the summer coat except 

 on the ears and feet, which have turned white. The male 

 specimen is a little more advanced in change, the ventral 

 surface, rump, and flanks having become white as well as the 

 ears and feet.
