I AM indebted to Mr. Swainson for the loan of three highly interesting examples of this species, from which 
specimens the figures on the accompanying Plate were drawn. I perfectly agree with this gentleman in con- 
sidering the lower one to be a very old male ; but with regard to the centre one I am rather uncertain, some 
appearances inducing me to believe it to be a young male in the state intermediate between youth and matu- 
rity, when it has acquired the perfect wings and tail but wants the brilliancy of the upper surface. I would 
here suggest that probably these birds may at some seasons, through the action of light and heat, lose the 
metallic lustre of their plumage, and consequently bear the sombre appearance of the centre bird in our Plate. 
Although not fully prepared to assert that this is the case, I am borne out in my opinion by discovering, on 
minutely examining the bird, that the wing-feathers are old, worn, and partly decomposed. The upper figure 
is without doubt that of an adult female. 
On examining other specimens of this bird in the collection of M. Natterer, I find that it is subject to a 
very unusual and considerable variation of its markings ; for although they all bear the general character- 
istics of the species, still scarcely two examples are to he found possessing strictly similar markings of the 
three lateral tail-feathers : in some specimens the black bars predominate, and in others the white ; I have 
reason to believe, however, that in very old males the black bars become partially obliterated, as exhibited in 
the lower figure of the accompanying Plate. 
The Trogon variegatus is a native of Brazil, where, M. Natterer informs me, it inhabits the woods bor- 
dering the rivers Negro and Paraguay. It was first discovered by Dr. Spix, in whose work is a good repre- 
sentation of the male : it will also form a conspicuous plate in Mr. Swainson’s exquisite work on the birds of 
Brazil.
