Tue bird here represented I conceive to be the true Falco radiatus of Latham ; it is but little known to 
ornithologists, from the circumstance that few specimens only have been sent to Europe. It inhabits the 
dense brushes bordering the rivers Manning and Clarence on the eastern coast of New South Wales, and 
doubtless enjoys a much greater range than we are at present acquainted with. It is the largest of the 
Goshawks inhabiting Australia, far exceeding in size the Astu palumbarius of Europe. In some parts of 
its structure it differs considerably from the typical Asturs, particularly in the lengthened form of the middle 
toe, in which respect it resembles the true Accipiters; in its plumage it somewhat differs from both 
those forms, the markings of most of the feathers taking a longitudinal mstead of a transverse direction ; 
these differences may hereafter be considered of sufficient importance to warrant its separation into a 
distinct genus, but for the present I have retained it with the other Goshawks in that of Astur. Of its 
habits and economy nothing whatever is known. 
The male has the whole of the upper surface blackish brown, each feather broadly margined with rust- 
red; wings brown, crossed by narrow bands of darker brown ; tail greyish brown, crossed by irregular bands 
of dark brown; shafts of the quills and tail buffy-brown ; throat buff, deepening into the rich rust-red of the 
under surface of the shoulder and the whole of the under surface ; all the feathers of the under surface with 
a narrow stripe of black down the centre; thighs and under tail-coverts rust-red without stripes. 
The female resembles her mate in colour and in the disposition of the markings, but has the striz of the 
under surface broader and more conspicuous. 
The figures are those of a male and a female about two-thirds of the natural size.
