to the first, but much narrower ; the primaries and secondaries 
are blackish, obscurely margined with blue on the outer web ; 
the under wing-coverts are whitish, a little intermixed with 
blue ; the tail is slightly emarginated, the feathers being black- 
ish, edged with blue on the outer web, and with white on the 
inner web at tip. 
The above description of this handsome bird is taken from 
a male in summer plumage, the only specimen' brought by 
Long’s exploring party ; hence we are unable to give any po- 
sitive information relative to the female and young, though, 
from analogy, we must believe them in great part destitute of 
the blue colour, and otherwise less brilliantly adorned. 
This species appears to be rather rare ; it is found along the 
Arkansaw River, near the base of the Rocky Mountains, du- 
ring the summer months ; they frequent the bushy valleys, 
keeping much in the grass, and seldom alight on shrubs or 
trees. In this respect, also, they resemble the Indigo bird, and 
probably their habits are the same, although the note is entirely 
dissimilar.

With the exception of a very imperfect description, little 
was known relative to this interesting bird, anterior to Long’s 
expedition to the Rocky Mountains. One of the notes annex- 
ed, to the account of that journey, contains an excellent descrip- 
tion of this swallow, with a notice of its habits, and remarkable
