The habitat of this species appears to be confined to the south-eastern part of New South Wales, for it has not as yet been found in any other portion of the country.

A single species only of this form has yet been discovered.

The brushes of the south-eastern part of Australia is the only locality in which this bird has yet been found.
Typical Orioles are widely distributed over Europe, Africa, Asia, the Indian Islands and Australia, but none have yet been discovered in Polynesia or America.
Three species inhabit Australia, two of which are figured; the third from the northern part of the country is so nearly allied to the _O. viridis_, that a description alone will be sufficient.
263. Oriolus viridis, _Gould_ Vol. IV. Pl. 13. 264. Oriolus affinis, _Gould_.
Inhabits the neighbourhood of Port Essington, and only differs from the preceding species in having a shorter wing, a much larger bill, and the white spots at the tip of the lateral tail-feathers much smaller.
265. Oriolus flavovinctus Vol. IV. Pl. 14.
Australia presents us with a single species of this genus; others inhabit New Guinea and the neighbouring islands; but as yet we have no evidence of the form occurring on the continent of India.

Nothing whatever is known of the nidification of this bird; in all probability it will prove to be very similar to that of the Orioles.
A genus containing only one species which possesses many singular habits; its actions among the branches, its mode of progression over the ground, and its nidification, being equally remarkable.
267. Corcorax leucopterus Vol. IV. Pl. 16.
_Bill_ shorter than the head, robust, swollen, arched above, deeper than broad; _gonys_ angular; _nostrils_ basal, lateral, round and open; _wings_ moderate, round, first primary short, the fourth and fifth the longest; secondaries long and broad; _tarsi_ scutellated in front, plain behind; _toes_ long and strong, the outer one longer than the inner one; _claws_ strong, compressed and much curved.
