"'^m/l THAYER AND BANGS — BIRDS 27 



nests were found, and Mr. Keren's notes contain no further 

 information. 



Harelda hyemalis (Linn.). 



Common along the whole Arctic Siberian coast. A number 

 remained throughout the entire winter of 1912-1913 at the Diomede 

 Islands, frequenting little spaces of open water among the ice. 

 One set of eggs, supposed to belong to this species, was taken, but 

 unfortunately it could not be positively identified. 



The harlequin duck ( Histnonicus histrionicus (Linn.)) was not 

 observed anywhere on the Siberian coast, though found commonly 

 south of Bering Strait on the Alaskan side. 



Polysticta stelleri (Pallas). 



Three specimens were taken at points along the Siberian Arctic 

 coast, and the species was found commonly all along the coast, 

 toward the east. Only one individual was seen so far west as 

 Nijni Kolymsk; this was on June 9, 1912. 



Arctonetta fischeri (Brandt.) 



The spectacled eider was not uncommon, and bred in the little 

 lakes in the tundra, apparently rather late in the season. On 

 July 12-15 large numbers, in the plumage of females, were seen 

 flying around or swimming in a lake thirty miles east of Cape 

 Bolshaja Baranov, but no nests nor signs of breeding could be 

 found. At Tenkurgin River, on Sept. 18, 1912, two families of 

 young were seen. They were following their parents in the water, 

 and were still unable to fly. 



One specimen was preserved.
