Tuts species of Aragari is distributed over Guiana, Cayenne, and the adjacent northern countries of tropical America, where it would seem to be very abundant, few collections being sent from thence to Europe which do not comprise specimens of both sexes. The living ee which Oniiaticyred the Gardens of the Zoological Society in 1844, afforded me an opportunity of ascertaining the colouring of the soft parts, which are correctly represented on the accompanying Plate, oe which were per oasly EOE, As will be seen, there is a marked difference in the colouring of the sexes, the female having the head, neck and throat chestnut instead of black, as in the male. The Plate represents the two sexes of the natural size.
