The female averages a more blunt bill, but this character is not so 

 marked as in the male. 



On examining a large series of White-winged Scoters from both 

 sides of the continent there is no difficulty in separating|Atlantic and 

 Pacific birds by means of this character of the bill. 



This subspecies I dedicate to Mr. Joseph Dixon of Escondido, 

 California, an untiring worker in the field, and a loyal companion in 

 the wilderness where the best laid plans at times miscarry.

This is an uncommon species on the north coast of Alaska. At 

 Demarcation Point none were seen until June 25, 1914, a single bird 

 on the Bay. An Eskimo brought me the unsexed skin of a specimen 

 shot by him on June 28 about ten miles east of the Point. On July 

 12 about fifteen were in the Bay associated with approximately the 

 same number of perspicillata. A male was taken from this flock. 



Oedemia perspicillata (Linne). 

 SURF scoter. 



On July 12, 1914, two flocks each containing about thirty individuals 

 were flying over Demarcation Bay, and in the Bay were some fifteen 

 with about the same number of White-winged Scoter. 



At Humphrey Point a male was taken by Mr. Dixon June 22, 1914.
