452 THE DIVING BIRDS — PYGOPODES. 



have been identical with the form since described as Colymhus Adamsii. It is com- 

 mon in the northwestern parts of North America, and said to be also of occasional 

 occurrence in England, Asia, and perhaps elsewhere. We have no notes touching its 

 specific peculiarities; and, indeed, it is not probable that these differ in any respect 

 from those of the common Loon. 



Mr. Bernard Eoss mentions his having met with it in considerable numbers in 

 Great Slave Lake. Mr. MacFarlane found it breeding, and obtained two eggs and 

 several specimens of the bird, in the vicinity of Fort Anderson and on the shores of 

 the Arctic Ocean. Specimens were also taken by Mr. Eoss at Fort Simpson, by Mr. 

 Clarke at Fort Eae, by Mr. J. Eeid on Big Island, and by Bischoff at Kadiak. 



This Loon was found to be quite common at Fort Resolution, where several speci- 

 mens were obtained by Mr. Kennieott in the summer of 1860, as well as on the 

 Yukon River. Mr. B. R. Ross secured specimens at Fort Norman and Fort Simpson. 

 It was obtained on Real's Eiver by Mr. Gaudet, on Big Island by Mr. John Eeid, 

 at Fort Eae by Mr. L. Clarke, at Fort Resolution by Mr. J. Lockhart, and on the 

 Anderson Eiver and in its neighborhood generally by Mr. MacFarlane. 



Mr. Whitely (" Ibis," 1867) and Mr. Swinhoe ("Ibis," 1867) speak of finding 

 this species common in the spring in Yezo. Mr. E. Adams — in honor of whom this 

 species was named by Mr. Gray — was present from October, 1850, to June, 1851, at 

 Michalaski, Alaska, on the shores of Norton's Sound. In his notes on the birds then 

 and there observed ("Ibis," 1878), mention is made of what is presumed to be this 

 form, known to the natives as the Too-oo-slik. He did not see any himself, but he 

 was told that this bird did not arrive before the end of August. The natives had in 

 their possession plenty of skins, which they convert into bags for their tools.
