I recrer exceedingly that it is not in my power to lay before my readers any account relative to the history of the elegant little Trogon figured in the accompanying Plate. My own specimen, which is a male, is the only one I have seen; I procured it during a recent visit to Paris, from a collection of South American birds : I was unable to obtain any information respecting its true habitat; but that portion of South America which extends from the Spanish Main to the River Amazon will in all probability ultimately prove to be its native locality. It is one of the least of the genus, and is rendered remarkable by the circumstance of the tarsi being thickly clothed down to the toes; the black bars on the outer tail-feathers are also broad, and well-defined; and, contrary to what obtains in every other species, these bars are not confined to the three lateral feathers, but the outer web of the fourth partakes of the same character, although to a less extent.
