This bird, brought from the Rocky Mountains by Major Long’s 
exploring party, is so closely allied to many imperfectly described 
species of the extensive genus to which it belongs, that ornitholo¬ 
gists, at first sight, may very reasonably doubt its pretensions to 
rank as a new species. But, notwithstanding any doubt that may 
be produced by its similarity to others, it is certainly an addition 
to the already numerous catalogue of Flycatchers. 
The total length of the Arkansaw Flycatcher is eight inches. 
The bill is similar to that of the Crested Flycatcher, but is more 
rounded above, and more abruptly inflected at tip, being of a black¬ 
ish colour, as well as the feet. The head above, and nucha, are 
pure pale plumbeous; the crown has a restricted bright orange spot 
in the middle, invisible when the feathers are at rest; there is a 
dusky spot between the bill and eyes. The cervix and back are 
pale pumbeous, tinged with olivaceous, and deepening on the rump 
almost to blackish, which is the colour of the superior tail coverts. 
The chin is whitish; the throat and upper part of the breast are 
of the same colour as the head, but paler; the remaining under 
surface, including the inferior wing and tail coverts, is yellow. 
The wings are brown, the secondaries being margined exteriorly 
with whitish; the inner webs of the primaries are whitish towards 
the base, and near the tips they are narrowed; the first is remark¬ 
ably so, being almost falciform. The tail is of a deep brown-black
