HISTRIONICUS HISTRIONICUS (Linnaeus). 

 HARLEQUIN DUCK. KAMENUSCHKA. 



The Harlequin Duck was very common at Unalaska about (he 

 rocky shores, usually in small Hocks. It was common about Atka, 

 whore one or two were seen inland on a small stream; on Attn and 

 Agattu it was also numerous on the streams as well as along the 

 coast; a number were seen at Copper and Bering islands, and a few 

 at Simushir in the Kurds. 



SOMATERIA V-NIGRA Gray. 

 PACIFIC EIDER. PISTRAK. 



The Pacific Eider was common at Agattu and Attu. On the 

 former island a nest with four eggs was found near the beach on 

 June S. This bird was usually seen along the rocky portions of the 

 shore, and was particularly numerous about Macdonald Bay, Agattu, 

 and the entrance of the harbor at Attu. 



OIDEMIA AMERICANA Swainson. 

 AMERICAN SCOTER. 



This scoter was seen in Puget Sound and about Union Bay, Van- 

 couver Island, but was not nearly so abundant as 0. deglandii or (>. 

 pt /sjricillata. 



OIDEMIA STEJNEGERI Ridgway. 

 STEJNEGER'S SCOTER. TURPAN. 



On September .'!() and ( >ctober 1, when among the small low islands 

 northeast of Yezo, and the southernmost Kurds, we found these 

 ducks very common, usually in small Hocks. As they were not seen at 

 this point when we passed in the summer, I judged those birds to be 

 migrants on their way south. We did not find them about the other 

 Kuril> nor about Kamchatka. 



OIDEMIA DEGLANDII Bonaparte. 

 WHITE-WINGED SCOTER. 



We saw a few White-winged Scoters on May 7 oil' the Oregon 

 coast, and on the next day found them abundant oil' the mouth of 

 the Columbia River. They were common everywhere in Puget 

 Sound, and very abundant at the time of our visit at Union Bay, 

 Vancouver [sland, far outnumbering any other duck. I saw a 

 single pair in I'nalga Pass, but did not meet with it again in the 

 Aleutians. 



OIDEMIA PERSPICILLATA (Linnaeus). 

 SURF SCOTER. 



In Puget Sound this duck was common, although not so abundant 

 a- 0. deglandii; it was common at Union Bay, ami a few were seen
