For this fine and hitherto uncharacterized species of Toucan, iny warmest thanks are due to W. Swainson, 
Esq., in whose valuable collection it is deposited, and who most liberally placed it at my disposal for the 
purpose of fijjuring, and at the same time allowed me to add a specific name on my own authority. In 
applying the term citreopygiis we have been influenced by the difference this species presents from all others 
in that peculiar character. Mr. Swainson informed me that this bird was originally in the collection of 
Mr. Bullock, from whom he purchased it, and who stated that he believed it was from Peru. 
Independently of the different colour of the upper tail-coverts, it possesses other peculiar characters. In 
size it equals Ramph. Cmieri, but differs from it in the colouring of the mandibles, and in the bill being much 
smaller in proportion to the body; the tail is proportionally shorter than is found in any other species, with 
the exception of Ramph. Toco, which in every other respect widely differs from it.
