One specimen, in the plumage of the old male as described by the 
Prince of Neuwied and Dr. Léotaud, and agreeing in every respect 
with a specimen from Brazil.

Both have the six middle tail-feathers of a davk metallic green, 
with scarcely any tinge of bluish; the rump and upper tail-coverts 
darker metallic green, with bluish reflexions. A young male from 
Demerara has the tail-feathers black, only the two innermost with 
green reflections on the outer web ; the outer tail-feathers are barred 
white and black at the apical half, like those of the female. 
We possess an old male from Cayenne, which shows a very pecu- 
liar difference (as far as I know, not yet mentioned by any describer), 
viz. in having the tail-feathers, instead of green in every light, with 
a dark indigo-blue lustre, and the greater part of the uropygium 
and upper tail-coverts vivid dark purplish blue. If new, 7’. eyanu- 
rus, Hartl.; otherwise it agrees in every respect.

Trogon curucui (L.); Cab. et Heine, Mus. Hein. iv. p. 176. 
One specimen, not different from a specimen from Surinam in the 
Bremen collection. 
T. curucui, Linné, based upon the description of Marcgrave and 
Brisson, is most probably this species, but cannot be made out with 
certainty. The white and black bars on the three outer tail-feathers, 
as described by Brisson, are very well referable to this species; but 
he does not mention the white cross band which separates the 
golden green of the jugulum and the scarlet of the breast. 
The figure of Trogon curucui by Hahn (Vog. aus As. Afr. Am. 
&e, Liefer. vii. t. 3) belongs undoubtedly to this species, and not to 
T. melanurus, Sw., as concluded by Dr. Cabanis (Mus. Hein. iv. 
p: 201).

A very good description of this species is given by Dr. Léotaud.
