98 BIRD NAMES. [No. 28. 



Wing marked with white as in male. Bill swollen, but without 

 the abrupt knob, and uniformly blackish; the eyes also very 

 dark. Legs and feet dull flesh color heavily shaded with black, 

 and with webs black. 



Young male. Kesembling female, but darker or more black- 

 ish about head and neck ; also noticeably darker on lower surface 

 of body, and showing, generally before the beginning of winter, 

 pinkish tinge on sides of bill (where the old drake is purplish 

 red), and having brighter and a little more reddish legs. 



In any plumage this species is instantly distinguished from 

 JSTos. 29 and 30 by the white wing-mark alone. 



Measurements (highest and lowest of eighteen freshly killed 

 birds) : length nineteen and five eighths to twenty-two and five 

 eighths inches ; extent thirty-three and seven eighths to forty 

 and three sixteenth inches. 



Eange, as given in A. O. U. Check List, 1886, " Northern 

 North America, breeding in Labrador and the fur countries; 

 south in winter to the Middle States, Southern Illinois, and 

 Southern California." I cannot remember killing one of, these 

 birds on the eastern coast south of the above limit, though they 

 are to be found farther south, doubtless. Dr. Coues says (Key, 

 1884) : "North America at large," etc.

 VELVET SCOTER: VELVET DUCK. 



From New Brunswick to Chesapeake region (in localities far 

 too numerous to mention) WHITE-WINGED COOT or WHITE- 

 WING. 



In Massachusetts at Pigeon Cove and North Scituate, BLACK 

 WHITE-WING for adult drake, and GRAY WHITE-WING for fe- 

 male and young; some gunners believing that these two plu- 

 mages represent separate species. 



Again in Massachusetts at New Bedford and Fairhaven, and 

 southward along the shore to Newport, R. I., the name MAY 

 WHITE-WING or GREAT MAY WHITE-WING is applied to certain 

 full-feathered birds, locally regarded as a distinct and larger 

 variety, to be met with only between the 10th and 20th of May
