Forehead and ear-coverts deep crimson-red; at the upper part of the back a broad patch of light chestnut-brown; the remainder of the plumage grass-green; on the flanks a spot of orange; primaries and secondaries black, broadly margined on the external webs with grass-green; base of all but the inner webs of the lateral tail-feathers deep red at the base, passing into yellow and tipped with grass-green; bill blackish brown, passing into reddish orange at the tip; cere and orbits olive-brown; irides buff, surrounded by a narrow circle of yellow. I was not aware, until after the impressions of the present plate had been printed, that Dr. Latham had applied the specific term of _Australis_ to this bird long before that of _concinnus_ was conferred upon it by Shaw; a fact, however, with which the accurate Wagler was acquainted, and which he has recorded in his valuable Monograph of the _Psittacidæ_ above quoted; the correct appellation of the species is therefore _Trichoglossus Australis_, Wagler. The figures are of the natural size. [Illustration: TRICHOGLOSSUS PORPHYROCEPHALUS: _Diet:_ _J. & E. Gould del._ _C.

This handsome little Lorikeet was first brought before the notice of the scientific world by Mr. Dietrichsen at the Meeting of the Linnean Society, held on the 20th of March, 1832; some confusion, however, exists as to the name then proposed for it. In a report of the Meeting published in the “Philosophical Magazine” for the same year it is called _Psittacus purpurea_; but in the seventeenth volume of the “Linnean Transactions” it is correctly placed in the genus _Trichoglossus_, with the far more appropriate specific appellation of _porphyrocephalus_, which I therefore retain. Although the Porphyry-crowned Lorikeet has been thus long described, it is still very rarely to be seen in collections, a fact which may be accounted for by the circumstance of its being an inhabitant of those parts of Australia with which we have hitherto had little intercourse. It is not found in New South Wales, and I do not recollect ever having seen it in collections from any of the eastern parts. It is abundant in South Australia, is equally numerous in the white-gum forests of Swan River, and in all probability is dispersed over the whole of the intermediate country. It is the only species of the genus I have seen from Western Australia, a circumstance which cannot be accounted for, since the face of the country is covered with trees of a similar character.
