We consider the primary divisions of the _Psittacidæ_, are those which have long been recognized under the familiar names of Maccaws, Cockatoos, Parrots, Lories, and Parrakeets. Such a series is the result of a synthetical investigation we have given to the subject; but this mode of inquiry is so deceptive, and has led to so many erroneous conclusions, that until each of these groups are submitted to a patient analysis, which has never yet been done, no correct opinion on the subject can be formed. The name on the Plate (engraved five years ago) is a mistake. The first description and figure of this bird is in "White's Voyage to New South Wales," where it is described as not uncommon. * * * * * * [Illustration: _White shoulder'd Ant Thrush_ (_M.

Nostro. ---- We found this remarkable bird not uncommon in the thick Forests of Pitanga, near Bahia, during our travels in Brazil in the years 1815-7. Yet although the male birds were frequent, we were never fortunate enough to procure a female. It has likewise been found in the southern provinces of that empire, by Dr. Langsdorff. Its total length is about seven inches; the whole plumage, with the exception of the snowy bands on the wings, is intensely black: the white spot on the back is only seen when the feathers are raised: the irides, in the live bird, are of a beautiful crimson. My friend M. Lesson, conjectures truly in thinking, that the birds placed by M. Temminck in our genus _Drymophila_, have no connexion or analogy with those species we have described, or with the characters on which we originally founded the group: they belong, in short, to a different family. * * * * * * [Illustration: _Red headed Tanager._ T.
