former place. The only island localities where the species was 

 observed were on the neighboring Btolin and Wrangell islands, 

 in close proximity to the mainland. On Etolin some sign was 

 observed, and I found a dead porcupine in the woods, but we 

 saw no living ones. On Wrangell, a number were observed. 



But one specimen was preserved, an adult female taken at 

 Thomas Bay on August 17 (no. 8352). This one is abnormal in 

 coloration, possibly albinotie. The whole animal is of a yellowish 

 color, about the clay color of Ridgway, becoming appreciably 

 darker on the rump. The lower surface is a dark grayish brown. 

 The short quills on the body are uniformly yellow, the larger 

 ones on the rump and tail yellow basally, but abruptly darker 

 at the distal end. The claws are of a dirty yellowish color. 

 Other porcupines seen at the same place, and at other points, 

 were all very dark, with the exception of one on Wrangell Island, 

 which was also rather pale colored, though not as markedly so 

 as the Thomas Bay specimen. The skull of the latter appears to 

 be that of an old animal and exhibits the peculiarities ascribed 

 to the form nigrescens by Allen, notably the fronto-parietal 

 depression, together with the great development of the temporal 

 ridges. 



Canis pambasileus Elliot. Alaska Timber Wolf. 



Wolves occur on all of the larger islands south of Frederick 

 Sound, as well as along the mainland, and we found signs of 

 their recent presence at most of the points we visited. About 

 our camp on Kupreanof Island there were abundant tracks, 

 apparently made by a single individual, while many of the dead 

 deer scattered through the woods, had quite evidently been 

 killed and devoured by wolves. At Three-mile Arm, Kuiu Island, 

 one was heard howling in the night. More or less fresh sign was 

 seen on Prince of Wales Island, at Port' Protection and at Klawak 

 Salt Lake, and at the latter place a skin was purchased from an 

 Indian, who had killed the animal the same morning. This 

 Indian informed us that wolves were particularly numerous 

 on several of the islands lying west of San Alberto Bay, islands 

 that we did not visit. Fresh tracks were seen on the beach at 

 Heeeta Island; and at Rocky Bay, Dall Island, wolf sign was
