The male has the crown of the head, ear-coverts, back of the neck, upper part of the back, upper tail-coverts and two central tail-feathers brown; stripe over the eye, and another from the base of the lower mandible down the side of the neck white; scapularies and lower part of the back rich chestnut; shoulders and wing-coverts black, each feather having a spot of white at the tip; primaries and secondaries dark brown, margined with lighter brown; lateral tail-feathers black, largely tipped with white; chin, throat and centre of the breast steel-black; sides of the chest and flanks brownish grey, the latter blotched with black; centre of the abdomen and under tail-coverts white; bill black; base of the under mandible lead-colour; irides reddish hazel; legs blackish brown. The female differs in having the whole of the plumage much lighter, and with only a slight tinge of chestnut on the rump; the stripes of white over the eye and down the sides of the neck less distinctly marked; the chin, throat and breast grey instead of black; the irides hazel, and the feet leaden brown. The figures are of the natural size. [Illustration: CINCLOSOMA CINNAMOMEUS: _Gould_. _J. Gould and H. C. Richter del et lith._ _Hullmandel & Walton Imp._ ] CINCLOSOMA CINNAMOMEUS, _Gould_. Cinnamon-coloured Cinclosoma. _Cinclosoma cinnamomeus_, Gould in Proc. of Zool. Soc., Part XIV. p. 68. We are indebted to the researches of that enterprising traveller Captain Sturt for our knowledge of this new _Cinclosoma_, which is the more interesting as forming an additional species of a singular group of Ground-Thrushes peculiar to Australia, of which only two were previously known. The specimen from which my figure is taken now forms part of the collection at the British Museum, and we learn from Captain Sturt that it was the only one procured during his lengthened sojourn at the Depôt in that sterile and inhospitable country, the interior of Australia. It is considerably smaller than either of its congeners, the _C. castanotus_ and _C. punctatum_, and, moreover, differs from them in the cinnamon colouring of the greater portion of its plumage. The whole of the upper surface, scapularies, two central tail-feathers, sides of the breast and flanks cinnamon-brown; wing-coverts jet-black, each feather largely tipped with white; above the eye a faint stripe of white; lores and throat glossy black, with a large oval patch of white seated within the black, beneath the eye; under surface white, with a large arrow-shaped patch of glossy black on the breast; feathers on the sides of the abdomen with a broad stripe of black down the centre; lateral tail-feathers jet-black, largely tipped with pure white; under tail-coverts black for four-fifths of their length on the outer web, their inner webs and tips white; eyes brown; tarsi olive; toes black.
