ACANTHIZA UROPYGIALIS, Gould.
Chestnut-rumped Acanthiza.
Acanthiza uropygialis, Gould in Proc. of Zool. Soc., Part V. p. 146; and in Syn. Birds of Australia, Part IV.
I received this new and well-marked species from New South Wales, with the belief that it had been collected either on the Liverpool Plains or the country immediately to the northward of them; but as there is some degree of uncertainty as to the locality in which it was procured, a knowledge of its true habitat would be very desirable, and I should have been happy to have cleared up this point had it been in my power so to do.
The chestnut colour pervading the basal half of the tail and the tail-coverts forms a very conspicuous mark, and presents a strong contrast to the remainder of the plumage. That its habits, actions and economy are very similar to those of the other members of the genus there can be no doubt, but on these points also I am compelled to silence, no notes of any kind having been sent with the specimens.
Head, upper surface and wings brown, slightly tinged with olive; the feather on the forehead tipped with a lighter colour; rump and upper tail-coverts rich reddish chestnut; tail-feathers brownish black, largely tipped with white, which on the two centre feathers is tinged with brown; throat, chest, and centre of the abdomen greyish white; flanks and under tail-coverts buffy white; bill and feet black.
The Plate represents the bird, which I believe to be a male, in two different positions.
