is difficult to kill, as it generally escapes from the 
opposite of the bushes, in which it takes refuge when 
pursued, or apprehensive of danger. 
In length it measures nearly eleven inches. The 
forehead, the cheeks, and the throat are white. The 
crown, the neck, and the whole of the under plu- 
mage orange-brown, with a purplish tinge, the sides 
of the neck in certain lights reflecting golden-green. 
On the lower part of the hind neck, and commence- 
ment of the mantle, is a large patch or demi-collar 
of blackish purple, the feathers terminated with shin-

is brown, with a greenish lustre in certain lights. 
Tail with the two middle feathers brown, the re- 
mainder on each side with their basal part black, 
the tips bluish-grey. Bill bluish-black. Legs and 
feet reddish-brown. 
The subjects of tlie four remaining Plates differ in 
many respects from all we have yet been engaged 
with, but whether they will form a separate division 
or the three first will enter among the Peristerinae, 
and the Lophyrus alone remain the representative of 
another group, we are unable to determine, not pos- 
sessing sufficient materials to institute so strict an 
analysis as is necessary, or to trace out with preci- 
sion the direct affinities of these species, and the si- 
tuation they hold in respect to the other groups of 
the Columbidm, as well as those of adjoining fa- 
milies. The three first we have provisionally in- 
cluded in the
