feathers. The female is stated to lay four or five eggs; the 
nestlings at first are covered with down, of a reddish-grey 
colour. 
The African species is said to diffuse a musky odour, which 
is retained even after the skin is prepared for the museum ; 
but we are inclined to believe that it is in the latter state only 
that it possesses this quality. Mr Peale did not observe any 
such odour in the bird he shot, but being obliged, for-want of 
better food, to make his dinner of it in the woods, found it not 
unpalatable.

Tae merit of having discovered this bird is entirely due to. 
the Peale family, whose exertions have contributed so largely 
to extend the limits of natural history. The male, which he 
has accurately described and figured, was made known to 
Wilson by the late venerable Charles Wilson Peale, who alone, 
and unaided, accomplished an enterprise, in the formation of 
the Philadelphia Museum, that could hardly have been ex- 
ceeded under the fostering hand of the most powerful Govern- 
ment. ‘To the no less zealous researches of Mr Titian Peale 
the discovery of the female is recently owing, who, moreover, 
evinced his sagacity by determining its affinities, and pointing 
out its true place in the system. Although it preserves the 
principal characters of the male, yet the difference is suffi- 
ciently marked to deserve an especial notice in this work.
