attempt to account for individual extremes of the latter by 

 referring them to carlottae and thus extendii^Lg its range into the 

 southern part of Prince of Wales Island, is, it seems to me, bound 

 to cause confusion. 



Two mainland specimens from Boca de Quadra (nos. 9755, 

 9761) are quite as dark above as any from Prince of Wales, while 

 others from Dall Island (no. 9752) and San Alberto Bay, Prince 

 of Wales Island (no. 9750) are indistinguishable from specimens 

 from Admiralty Island and other more northern points. 



Seventeen specimens of the Steller jay were collected, as 

 follows: Kupreanof Island, three (nos. 9745-9747), Coronation 

 Island, one (no. 9748), Heceta Island, one (no. 9749), Prince of 

 Wales Island, Calder Bay, one (no. 9760), San Alberto Bay, one 

 (no. 9750), Klawak, one (no. 9751), Dall Island, three (nos. 9752- 

 9754), Etolin Island, one (no. 9756), Mitkof Island, two (nos, 

 9757, 9758), Boca de Quadra, two (nos. 9755, 9761), and the 

 Taku River, one (no. 9759). 



Corvus corax principalis Ridgway. Northern Raven. 



Seen at every point we visited, sometimes in considerable 

 numbers. They were usually quite tame, and made no effort to 

 get far out of our way, while at several of our camps the ravens 

 visited us daily for the purpose of carrying off refuse — the bodies 

 of skinned birds and mammals, or the scraps trimmed from bear 

 or deer skins. From the actions of some of the birds seen on 

 Kuiu Island the first week of May, and at Klawak Salt Lake, 

 Prince of Wales Island, towards the end of the same month, I 

 judged them to have nests near by, containing eggs, or more 

 probably young, but I was unable to find them. At Etolin Island, 

 July 5 to 12, a brood of noisy young ones hovered about the camp 

 daily, the old ones assiduously feeding them on the scraps I 

 threw out, a process accompanied by gasping, choking, and gurg- 

 ling noises. 



One specimen of the northern raven was preserved, a juvenal 

 female, Etolin Island, July 8 (no. 9762). This bird is just 

 molting from the juvenal into the first winter plumage, with 

 lines of glossy black feathers appearing in the pectoral tracts, 

 on the throat, and on the top of the head.
