This is a very large species, being nearly equal in size to the 7. 
gigas; its deep green colouring and blue wings render it easily di- 
stinguished ; the female differs considerably from the male, inasmuch 
as nearly the whole of the under parts of the body are of a rust-like 
tint; the two outer tail-feathers are of a blackish colour, but have a 
white shaft ; the outer web is grayish-white, excepting at the margin 
and at the apex of the feather; the outer edge of the first primary is 
palish.

The green on the upper parts of the body of this little species is 
rather paler, and has a greater admixture of the golden lustre, than 
usual: words can convey no idea of the brilliancy of the large ruff 
on the throat; in some lights it assumes a deep blood-red ‘hue; in 
others there is a slight admixture of purple observable ; in others, 
again, they put on a brilliant cupreous-red tint, as we observe in the 
copper ore.

This small-sized species has the wing and tail-feathers narrower 
than usual.

This is in all probability a young bird, or perhaps a female of some 
species, the male of which remains to be discovered; the yellow
