F o r this fine and hitherto uncharacterized species of Toucan, my 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 figuring, and at the same time allowed me to add a specific name on my own authority. In
applying the term citreopygus 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. Cuvieri, 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.
