Tue accompanying Plate of this elegant species is copied by permission from a beautiful lithograph by Mr. Lear, whose drawing was made from two living birds in the possession of the Countess of Mountcharles. It will be seen on reference to the synonyms that this bird was known to Dr. Latham nearly forty years ago, when he published a good description of both sexes under the name of Psittacus Nove-Hollandie : it is only lately, however, that it has become abundant in the collections of Europe; previous to which specimens were so rare, that when they became more numerous several modern ornithologists characterized and described the bird as a new species under various names, but the old appellation of Nove-Hollandie should in my opinion be retained for it. A fine example of the female is at this time living in the gardens of the Zoological Society, in excellent health and in full plumage. This species has many of the actions of the Platycerci, being extremely active, and running round its cage with a surprising agility, in which particular it is equalled only by the most terrestrial members of the family. To give some idea of the immense flocks of this bird which inhabit the interior of Australia, I may mention that in a letter lately received from my brother-in-law Stephen Coxen, Esq., | am informed that he procured more than two hundred examples during a single excursion into the interior.
