Fuligula glacialis. 



Harelda, Stephens-]-. — Bill much shorter than the head, its outlines tapering 

 rapidly to the tip, which is occupied by the broad, prominently decurved nail ; 

 lamellas slightly exposed along the gajie-line ; nostrils oblong, sub-basal. 

 Feathering at the base of the bill forming an oblique line, advancing furthest 

 forward on the forehead, and scarcely interrupted by the re-entrant angle so 

 prominent in most Ducks. Wings rather sboit, pointed ; scapulars much elon-

 graduated, the two central feathers in the adult male very long and tapering. 

 Legs short, placed far back ; hind toe small, but broadly lobed.
