1875.] MR. SHARPE ON THE ACCIPITRES OF AUSTRALIA. 337 
5. Contributions to a History of the Accipitres, or Birds of 
Prey. By R. Bowpier Suarpz, F.L.S., F.Z.S., &c., of the 
Zoological Department, British Museum. Notes on the 
rarer Accipitres of Australia. 
[Received April 19, 1875.] © 
The specimens which I have the pleasure of exhibiting before the 
Society to-night have all been collected in the interior of Queensland 
by Mr. J. B. White, a gentleman whom Mr. Ramsay ‘has already 
introduced to the notice of ornithologists as the discoverer of the egg 
of Chlamydodera maculata (pide P. Z. S. 1874, p. 605). During 
a recent visit to England Mr, White submitted his series of Accipi- 
tres tome; andI found so many interesting birds among them, many 
in stages of plumage hitherto unknown and undescribed, that I have 
put together a few notes on the must important species.

Urospizias radiatus, Sharpe, Cat. B. i. p. 159. 
Mr. White has an adult male and a young female of this interesting 
bird; and it is quite evident that my measurements, taken from a 
supposed female bird in the Museum collection, were wrongly given 
by me in the ‘ Catalogue.’ Mr. White’s birds measure as follows :— 
¢ ad. Total length 20°5 inches, culmen 1°35, wing 14°9, tail 9-2, 
tarsus 3. 
Q jun. Total length 24:5 inches, culmen 1°6, wing 16:9, tail 
10°5, tarsus 3°25. ‘ : 
Young female. Larger than the male, as will be seen by the 
measurements, and immensely more powerful in the talons. Above 
tolerably uniform brown, the hind neck mottled with white bases to 
the feathers, a few of the feathers on the hind neck and upper wing- 
and tail-coverts showing the characteristic bright rufous margins ; 
median and greater wing-coverts shaded with ashy grey, and barred 
across with dark brown, exactly like the secondaries, which are out- 
wardly greyish with four distinct bands of dark brown, the tips of 
the feathers whitish ; the primary coverts and primaries greyish, barred 
with blackish, about nine bands being distinguishable on the latter ; 
on al] the feathers of the rump and upper tail-coverts are indications 
of concealed greyish white cross bars, many of the latter being also 
tipped with white ; tail-feathers grey, narrowly tipped with white and 
crossed with nine bands of blackish brown, increasing to ten in num- 
ber on the outer tail-feathers ; sides of face brown, the lower ear- 
coverts streaked with white; cheeks and throat white, distinctly 
streaked with blackish brown; all the rest of the under surface 
broadly streaked with blackish brown, the chest washed with tawny ; 
the centre of the body white, the flanks greyish, many of the feathers 
margined with bright rufous ; thighs entirely bright rufous, entirely 
uniform; vent and under tail-coyerts whitish, with narrow blackish
