The Spine-tailed Orthonyx is very local in its habitat, being’ entirely confined, so far as I have been enabled to 
ascertain, to the brushes which skirt the southern and eastern coasts of Australia, such as occur at Illawarra, 
and in the neighbourhood of the rivers Manning, Clarence and MacLeay. It is usually found in the most 
retired situations running over the prostrate logs of trees, large moss-covered stones, &c. ; further than 
this, nothing is known of its habits and economy. I ascertained by an examination of the stomach that the 
food consists of insects, principally of the order Coleoptera, and that the white throat distinguishes the 
male and the rufous throat the female. A knowledge of the situation and form of its nest and the number 
and colour of its eggs would probably afford some clue to its real affinities ; at present I do not know to 
which group it truly pertains, and I very much regret that circumstances did not admit of my settling this 
point by a further observation of the bird in a state of nature : as it is very solitary in its habits it is seldom 
seen, and it would consequently require many months’ residence to become tolerably acquainted with it, and 
to acquire a knowledge of these desirable facts. 
The male has the crown of the head and upper part of the back reddish brown, with a large mark of 
black on each feather ; lower part of the back and upper tail-coverts rich rufous brown ; wings black ; 
coverts largely tipped with grey ; primaries crossed with grey at the base ; apical half of the primaries and 
the tips of the secondaries dark brownish grey ; tail dark brown ; sides of the head and neck dark grey ; 
throat and chest white, separated from the grey of the sides of the neck by a lunar-shaped mark of deep 
black ; flanks and under tail-coverts grey, stained with reddish brown ; bill and feet black ; irides very 
dark hazel. 
The female only differs in colour in having the throat rich rust-red. 
The Plate represents the male and female of the size of life.
