314 ANATID^E : SWANS, GEESE, AND DUCKS. 



head and anterior parts of the body brown, and other parts which 

 are black in the male here brownish. Region about base of bill 

 white. Length about 20.00 ; extent, 29.00 ; wing, 9.00 ; bill, 2.10 ; 

 tarsus, 1.50. 



One of the winter residents along the coast, rather 

 common at that season, but, as usual with birds of this 

 family, more numerous during the migrations, when 

 those that have wintered farther south, or bred in 

 the high north, pass through New England. It is an 

 expert diver, and usually found in flocks of considerable 

 size. 



LESSER SCAUP DUCK. 



FULIGULA AFFINIS EytOH. 



Chars. Very like the last ; gloss of head purplish rather than 

 green ; flanks and scapulars less closely vermiculated ? Size 

 less ; length about 16.00 ; wing, 8.00. Difficult to define 

 specifically, and perhaps only a variety of the last ; it appears, 

 however, to preserve certain distinctions, though constantly 

 associated with F. inarila. 



This Duck is doubtfully a distinct species from the 

 last, with which it is found associated, occurring under 

 the same circumstances. Both are properly sea-ducks, 

 though occasionally found inland. 



RING-NECK SCAUP DUCK. 

 FULIGULA COLLARIS (Donov.) Bp. 



Chars. Male : resembling the last two species ; back nearly 

 uniform blackish ; an orange-brown ring round the neck ; 

 speculum gray ; bill black, pale at base and tip. Female : no
