In the Male, the middle age may be distinguished from the adult by the grey freckles on the 
wings being rather stronger and more inclined to brown on the secondaries ; by the 
extreme outer edge of the primaries being white; and by the tail being regularly barred 
with black and white, which character is most conspicuous on the outer edges. 
Remale. The top of the head, throat, chest, and back dark brown, inclining to olive on the 
upper surface and to rufous on the chest; across the chest an obscure band of light grey; 
the upper part of the belly brownish grey, the lower part and vent scarlet; wings black, 
slightly freckled with brown on the outer edges of the secondaries and shoulders; the 
outer edges of the primaries fringed with white; two middle tail-feathers chestnut brown 
tipped with black, the two next on each side wholly black; the remainder strongly 
barred with black and white for nearly their whole length ; bill yellow clouded with 
brown. 
Trogon Mexicanus. Swains., Phil. Mag. June 1827, and Zool. Ilk, 2nd Ser., pk 82. young 
male, pk 107 - female. 
In the description which accompanies the preceding Plate I have stated my reasons for considering that and 
the present bird as constituting one and the same species. In the Plate accompanying this description I have 
given in illustration of this opinion a figure of a male bird killed in a youthful state; when, as may be readily 
perceived, it had nearly accomplished the change in the plumage of the body, while one single feather alone 
has appeared in the tail: this new feather possesses all the marks of maturity, and may be easily distinguished 
from the rest by its being entirely free from the bars of black and white. The specimen from which this 
drawing has been taken is in the possession of John Taylor, Esq., who received it with several others from 
Mexico. 
The Trogon Mexicanus was, I believe, first described by Mr. Swainson in the Philosophical Transactions 
for June 1827: since that period he has figured the young male and the female in the Second Series of his 
Zoological Illustrations (pis. 82 and 107). While travelling on the Continent I collected several specimens 
of this bird, and ascertained, by means of the labels attached, that it is identical with the Trogon glocitans of 
Professor Lichtenstein. I believe that the name of Mexicanus claims priority; and if so, glocitans must of 
course give place to it: but on this point I cannot speak with certainty.
