TOO SYSTEM A TIC SYNOPSIS. — LAMELLIBOSTBES — AN SERES. 



not shorter tha^ head and rising high on forehead ; nail at end distinct, decurved, narrow, 

 less than one-third as wide as end of bill; frontal feathers extending to approximately equal 

 distances on top and sides of upper mandible, with a well-marked reentranoe between them 

 reaching hack to about opposite angle of the mouth, those of chin advancing rather farther. 

 Nostrils in basal two-fifths of bill (nearly median in F. valUsneria). Outline of upper man- 

 dible gently concave to the decurved naU; sides nearly parallel, or widening toward end (whole 

 bill much as in ordinary Anatmce). TaU short, rounded, less than half as long as wing, 

 14-16-feathered. Tarsus less than f (i-f) as long as middle toe and claw. Head not crested 

 or notahly pufiy (in our species). Head and neck black, brown or chestnut (not green with 

 great white patches). Sides and back finely waved with black and white. Lining of wings 

 white. Crissum black. Bill blackish, or black and blue. Legs dark. Speculum white or 

 gray. (Comprising several species of " black-head " and " red-head " ducks, including the 

 "canvas-back"; characters drawn up on consideration of these species; requiring modifica- 

 tion, especially as-to color, to include the European F. rufina, by some considered type of 

 the genus. Equivalent to FuUx, Aythya and Aristonetta of Baird, 1858, and apparently sepa- 

 rable into three full genera — one for the crested pochards of Europe ; one for the black-heads 

 and red-heads together; and one for the canvas-back alone. The type of Fuligula is said by 

 Sundevall to be F. cristata ; in which case CalUehen is available for rufina.)
