the middle of the wing is chestnut brown, the lesser 
covers and lower half of the greater, velvet black ; 
the upper half of the greater covers pure white, 
forming a marked and conspicuous spot, quills dark 
clove-brown. The female is described as having 
the under parts pure white, except the lower part 
of the neck and breast, where the crescented bands 
are broader, and are of dark brown and pale buff. 
The upper parts are less distinctly marked.

and fit into each other. We cannot conceive a 
more beautiful apparatus to retain what is wished ;

the same purpose here which the “ Rakers,” do in 
the gills of the Coregoni and some other genera of 
fishes.
