that examples were obtained by Natterer in Minas Geraes, and at Monjolinha; and I have myself received 
it from other parts of Brazil: that country would therefore appear to constitute its natural habitat. Bur- 
meister, who obtained a male near New Freiburg, states that this species is not so abundant as the 
Trogon viridis, that the Prince of Wied did not meet with it, and that consequently it must be regarded 
as a Brazilian bird. Much difference exists in the colour of the upper surface of different specimens, par¬ 
ticularly of the head and throat, some having those parts of a rich violet purple, while in others they 
are of a rich metallic green; but as I find no variation in their relative admeasurements, I am led to 
regard them as merely varieties of the same species. The plumage of the young males resembles that of 
the female; but their central tail-feathers are at all times glossed with green on the upper surface: still they 
are apt to puzzle the ornithologist, unless he has made himself acquainted with the peculiar variations in 
colour to which the immature birds of this family are subject from the circumstance of the feathers of the 
body frequently undergoing a change before those of the wings and tail. I have a specimen in my collection, 
in which an almost perfect moult has taken place in the plumage of the body, its tint being nearly as rich 
as that of the adult: this specimen is also rendered remarkable by the centre of the wing having assumed 
the minute markings of maturity, while the tail resembles that of the female, in which the white only 
occupies the outer webs and extreme tips of the three lateral feathers. 
The Plate represents a male and female, of the natural size. The plant is the Passi/lora tinifolia.
