DUCK. 315 



Bancroft, in his History of Guiana, mentions a Teal, somewhat 

 larger than the Common one ; the bill broad and black ; feathers of 

 the head whitish brown ; those of the neck, back, and wings, grey 

 brown, variegated with spots and bars of chestnut; breast and belly 

 dull white. I suspect this to be the same with my bird, but certainly 

 distinct from the European Shoveler. He says, that it frequents the 

 rivers, like the Guiana Wild Duck, and at the same seasons.

THIS is a trifle bigger than the Common Teal. Bill large, 

 broad, very tumid above the nostrils, and bifid in the adult bird ; 

 the end marked with diverging striae, colour blue; head and part 

 of the neck white ; on the crown a large patch of black ; eyelids 

 black ; middle of the neck the same ; fore part of the bod}' 

 yellowish brown, undulated with black; back clouded with cine- 

 reous and pale yellow, powdered with brown ; under parts of the 

 body and rump greyish brown, in some lights appearing glossy grey; 

 wings small, without any speculum; tail longish, of eighteen feathers, 

 cuneiform, and black; legs brown, bluish before, and placed far 

 back, as in the Diver Genus. 



The female, and young bird, have the bill less tumid at the 

 base, and wholly brown ; throat white, expanding towards the 

 nape. — This species frequents the greater lakes of the al Moun- 

 tains, and the River Ob, and Irtisch ; not seen on the ground, for. 

 from the situation of the legs, it is little able to walk, but swims 

 very well, and quick ; at which time the tail is immersed in the
