white. The color of the back, as given in the figure of bonapartii, is much more like the usual 
average of specimens of canadensis than as figured for the latter species.

MYIODIOCTES BONAPARTII, And. 
Bonaparte's Flycatcher. 
Muscicapa bonapartii, Aud. Orn. Biog. I, 1831, 27; pi. 5. 
Setophaga bonapartii, Rich. List, 1837. 
Wihonia bonapartii, Bonap. List, 1838. 
Myiodioctes bonapartii, Aud. Syn. 1839, 49. — Ib. Birds Amer. II, 1841, 17 ; pi. 73. 
Sylvania bonapartii, Nuttall, Man. I, 2d ed. 1840, 332. 
" Bristles longer than in the last, second quill longest ; tail very long, nearly even ; upper parts light greyish blue ; quills dusky 
brown, their outer webs greyish blue, the two outer margined with white ; middle tail feathers and edges of the rest like the 
back ; lower parts and a band on the forehead ochre yellow, with a few faint dusky spots on the lower part of the fore neck. 
This species differs from the last chiefly in being of a more elongated form, in having the bristles much longer, the upper 
parts of a much lighter tint ; in wanting the black band down the sides of the neck, and the yellow band over the eye ; the bill 
is straighter and more pointed, and the outer primaries are edged with white. Male, 5.4 inches." 
Hab. — Louisiana. 
To complete the history of the species of Myiodioctes, I copy the description from Mr. 
Audubon of the M. bonapartii ; as already stated, however, it is quite likely that it may prove 
to be only an immature M. canadensis. 
CARDELLINA, Dub us. 
Cardellina, Dubus, Bp. Consp. Av. I, 1850, 312. 
Ch. — Bill short, compressed ; higher than broad at the base. Culmen gently convex; tip not decurved ; notch not very 
prominent. Tail nearly even, about equal to the wings, which is considerably rounded; the first quill about equal to the sixth, 
the third longest. Colors partly red. 
This genus, in the shortness and compression of its bill, resembles Parus to a considerable 
degree. The only species I have occasion to mention is entirely red, with white ear patches.
