The sexes present no external difference whatever, neither is there much difference in size; the young are black from the nest, except that the tertiary feathers are strongly tipped with white, a character never I believe thrown off in adult age. All the plumage brownish black, becoming much browner on the tips of the wing-feathers, and of a grey tint on the abdomen; base of the inner webs of the primaries and secondaries, the under tail-coverts and the apical third of the inner webs of the tail-feathers white; irides orange-yellow; bill and feet black; corner of the mouth yellow. The Plate represents the bird about four-fifths of the size of life. [Illustration: STREPERA ANAPHONENSIS. _J. Gould and H. C.

Having formerly considered the Grey Crow-Shrikes of New South Wales and Western Australia as distinct species, I assigned to the Swan River bird the specific appellation of _plumbea_; subsequent research has, however, proved them to be identical: I am therefore under the necessity of adopting the name of _Anaphonensis_, previously applied to the species by my friend M. Temminck, and of sinking that of _plumbea_ into a synonym. No one species of the genus has so wide a range as the present, extending as it does from New South Wales on the east to Swan River on the west coast. It is, however, more local in its habitat than any of them, at least such is the case in New South Wales; for although it is tolerably abundant at Illawarra, at Camden, and in the park of C. Throsby, Esq., at Bong-bong, it was not seen in any other district that I visited. Mr. Gilbert states that he observed it in every part of Western Australia visited by him; and that he mostly met with it in the thickly wooded forests, singly or in pairs, feeding on the ground with a gait and manners very much resembling the Common Crow. Its flight is easy and long-sustained, and it occasionally mounts to a considerable height in the air. Its note is a piercing shriek, very much resembling in sound the native name. The stomach is very muscular, and the food consists of coleoptera and the larvæ of insects of various kinds. It breeds in the latter part of September and the beginning of October, forming a nest of dried sticks in the thickest part of the foliage of a gum- or mahogany-tree and laying three eggs, the ground-colour of which is either reddish buff or wood-brown, marked over nearly the whole of the surface with blotches of a darker tint; their medium length is one inch and nine lines by one inch and two and a half lines broad.
