This is a very large species, being nearly equal in size to the T. 

 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
