at tip, marked by four yellowish-wliite spots on the 
exterior, and by two larger ones on the inner web. 
The specimen of the rocky mountain antcatcher we 
are describing, is a male, shot in the month of July, and 
possibly not adult. As it is the only one brought by 
Major Long’s party, we cannot determine the extent or 
nature of the variations the species may undergo from 
age, sex, or season. 
The note of this bird is peculiar, resembling the harsh 
voice of the terns. It inhabits the steril country 
bordering on the river Arkansaw, in the neighbour- 
hood of the Rocky Mountains, where it is frequently 
observed hopping on the ground, or flitting among the 
branches, and weather-beaten, half-reclining trunks of 
a species of juniper: when it flies among the crooked 
limbs of this tree, it spreads its tail considerably, but was 
never seen to climb. They were generally observed 
in small associations of five or six individuals, perhaps 
composing single families.

BONAPARTE, PLATE I. FIG. III. 
The female of this pretty little warbler, hitherto 
unknown to any naturalist, is now described for the 
first time. For the opportunity, we are indebted to 
Mr Titian Peale, who shot it on the 24th of May, near 
Camden, New Jersey; and, with his usual kindness 
and zeal for natural history, communicated it to us for 
this work. 
This little warbler differs so materially from its mate, 
as to require a distinct description, in order to be recog- 
nized; yet we cannot fail to perceive a kind of family 
resemblance between the sexes ; and, by comparing 
the two descriptions, our readers will agree with us 
that they are but one and the same species, in a different
