line of I'ich yellow ; a similar yellow line from the lower mandi- 

 ble, round to the back of the neck, joining the first, and enclos- 

 ing the black patch ; a spot below the eye, also yellow; breast 

 yellow ; flanks marked with yellow, black, and white, the black 

 predominating ; axillaries, belly and vent, pure white ; bill and 

 feet black, the soles of the latter, yellow. Length 5 inches. 

 Extent of winors 7 inches. 



I procured but one specimen of this beautiful bird, on the Co- 

 lumbia river, in the spring of 1835. Early in autumn of the same 

 year, I shot another male, in a somewhat plainer livery. 



It does not breed there, and I know nothing of its habits. 



Audubon's Warbler. 

 Sylvia *Audvboni, (Townsend.) Journal Acad. Natural 

 Sciences, Vol. 7, part II., p. 191. Audubon's Birds of America, 

 Vol. IV., pi. 395. Male and female. 



Bill slender, black; upper parts light plumbeous; crown, 

 throat, rump, and sides under the wings, gamboge yellow ; lores, 

 and a broad space behind and below the eye, including the auri- 

 culars, black ; a white spot above and below the eye ; feathers 

 of the back with large, pointed spots of black, occupying the 

 shafts, and a portion of each vane ; wings dusky, all the feathers 

 edged exteriorly with grayish ; wing-coverts tipped with white, 

 forming a large spot below the shoulder ; upper tail-coverts light 

 plumbeous, largely lipped with black ; tail long, nearly even, 

 blackish, edged with dark gray, and every feather, except the 

 two middle ones, with a large spot of white on the inner vane, 

 near the tip ; breast and sides of the belly, black ; medial por- 

 tion of the latter, vent and inferior tail-coverts, white ; legs and 

 feet brownish-black. Irides dark hazel. Length 5 inches. 



The female has the upper parts brownish, spotted and streaked 

 with black ; the yellow on the crown, rump, and flanks is more 

 restricted and fainter than in the male, and it wants the large bed 

 of white upon the wing; throat white; breast and belly varied 

 with black and white. 



Very common on the Columbia river in the spring, where it 

 breeds. It sings quite prettily, but, like some others of its family, 

 is rather monotonous. The note very much resembles that of 

 S. coronata, to which the species is closely allied, but unlike the 

 bird just named, it keeps in the thickest and most impervious
