THE TYRANT FLYCATCHER.— KING-BIRD. 
This bird lias the mouth wide, the palate flat, with two longitudinal ridges, 
its anterior part horny, and concave, with a median and two slight lateral 
prominent lines ; the posterior aperture of the nares oblongo-linear, papillate, 
4 \ twelfths long. The tongue is six-twelfths long, triangular, very thin, 
sagittate and papillate at the base, flat above, pointed, but a little slit, and 
with the edges slightly lacerated. The oesophagus is 2J inches long, with- 
out dilatation, of the uniform width of 3 twelfths, and extremely thin ; the 
proventriculus 3e twelfths across. The stomach is rather large, broadly el- 
liptical, considerably compressed ; its lateral muscles strong, the lower thin, 
its length 10 twelfths, its breadth 8 twelfths, its tendons 4J twelfths in 
breadth; the epithelium thin, tough, longitudinally rugous, reddish-brown. 
The stomach filled with remains of insects. The intestine is short and wide, 
7 inches long, its width at the upper part 4 twelfths, at the lower 2 twelfths. 
The coeca are 2 twelfths long, h twelfth in breadth, and placed at an inch and 
a half from the extremity. The rectum gradually dilates into the cloaca, - 
which is 6 twelfths in width. 
The trachea is 2 inches 2 twelfths long, considerably flattened, 2 h twelfths 
broad at the upper part, gradually contracting to li twelfths ; its rings ,56, 
firm, with 2 dimidiate rings. It is remarkable that in this and the other 
Flycatchers, there is no bone of divarication, or ring divided by a partition ; 
but two of the rings are slit behind, and the last two both behind and before. 
Bronchial rings about 15. The lateral muscles are slender, but at the lower 
part expand so as to cover the front of the trachea, and running down, termi- 
nate on the dimidiate rings, so that on each side of the inferior larynx there 
is a short thick mass of muscular fibres, which are scarcely capable of being 
divided into distinct portions, although three pairs may be in some degree 
traced, an anterior, a middle, and a posterior. These muscles are similarly 
formed in all the other birds of this family, the Muscicapince, described in 
this work,

The outer two primaries attenuated at the end, the second longest, the 
first longer than the third; tail even. Upper parts dark bluish-grey ; the 
head greyish-black, with a bright vermilion patch margined with yellow ; 
quills, coverts, and tail-feathers brownish-black, the former margined with 
dull white, the latter largely tipped with white ; lower parts greyish-white ;
