Chestnut-breasted Ground Thrush.

For a knowledge of this richly coloured and very distinct species of Ground Thrush, science is indebted to 
Charles Coxen, Esq., who discovered it in the scrubby belts of trees growing on the table-land to the north- 
ward of the Darling Downs in New South Wales. In size it nearly equals the Cinclosoma castanotus, but 
differs from that bird in the buffy stripe over the eye, in the colouring of the back, and in the band of 
chestnut-brown which crosses the breast. I regret to say that only a single male specimen has yet been 
forwarded ; I trust, however, that through the kindness of Mr. Coxen or some other lover of natural history, 
we may ere long he favoured with an example of the female. 
Every ornithologist will I am sure hail the discovery of this new species with pleasure, since it is not only 
an interesting addition to the ornithology of Australia, but an additional species to a singular form, of which, 
when I commenced my work on the Birds of that country, hut one species, the Cinclosoma punctatum, was 
known ; I myself shot for the first time the C. castanotus in the Murray scrub ; and Captain Sturt had the 
honour of making us acquainted with the beautiful little species to which I have given the name of cinna- 
momeus ; with the addition of the present bird, four well-defined species of the genus are now known to 
exist. Are there not others yet to come ? Yes, in all probability, but we must wait for them until the vast 
tracts of hilly and sterile country to the northward of Moreton Bay have been explored, for it is not in the 
rich plains that the members of this group are to be found ; stony ridges and deep rocky gullies are more 
favourable to their habits and modes of life. 
Crown of the head, ear-coverts, back of the neck and upper tail-coverts brown ; stripe over the eye and 
another from the base of the lower mandible, down the side of the neck, white ; shoulders and wing-coverts 
black, each feather with a spot of white at the tip ; all the upper surface, the outer margins of the scapularies 
and a broad longitudinal stripe on their inner webs next the shaft deep rust-red ; primaries, secondaries, 
and the central portion of the scapularies dark brown ; tail black, all but the two central feathers largely 
tipped with white ; chin and throat black ; chest crossed by a band of rich rust-red ; sides of the chest and 
flanks brownish-grey, the latter blotched with black ; centre of the abdomen white ; under tail-coverts brown, 
deepening into black near the tip, and margined with white ; hill and feet black. 
The figures are of the natural size.
