length, but in plumage is perfectly similar to the male. As 
the male we have described and figured is evidently a young 
bird, it is very probable that the adult, after undergoing the 
changes usual in this group, obtains a much darker and more 
uniform plumage above, and is beneath lineated transversely 
with reddish. That in this supposed plumage the bird has 
not yet been found, is no reason to doubt its existence, as the 
species is comparatively rare. Hven of the common Falco 
Juscus, though constantly receiving numerous specimens of the 
young, we have only been able to procure a single one in adult 
plumage during a period of four years. 
We regret that this is all that is in our power to offer of 
the history of this species, which, as will be seen from the 
description, possesses in an eminent degree the characters of 
the group. From the circumstance of its being found here in 
autumn and winter, we are led to infer that it comes to us 
from the north.
