practical acquaintance with the ornithology of the district, 
was not acquainted with it, and had not previously met with 
specimens.

Museum / by R. Bowdler Sharpe (1874) . By J. H. Gurney.

(Plate III.) 
Mr. Sharpe places at the head of his subfamily “ Buteoninae” 
the “ Radiated Goshawk” of GouhPs f Birds of Australia/ 
under the title of “ Urospizias radiatus.” 
I have already pointed out (Ibis, 1875, p. 364) that the 
generic name of Urospizias is not properly available for this 
species; and Mr. Sharpe has subsequently applied to it the new 
generic appellation of “ Erythrotriorchis,” which had been 
suggested as a suitable substitute ( vide Notes by R. B. Sharpe 
on the rarer Accipitres of Australia, in P. Z. S. 1875, p. 337). 
The two measurements given in Mr. Sharpe’s Catalogue as 
those of a male and female of this species, have evidently 
both been taken from male birds; and in the paper above re¬ 
ferred to, Mr. Sharpe corrects this inadvertence, and gives the 
measurements of an actual male and female, recently obtained 
by the British Museum from the interior of Queensland, to¬ 
gether with a description of the female, which is in immature 
plumage, a stage in which this species had not been previously 
described. 
Having myself had a recent opportunity of measuring an 
adult female of this rare Hawk, I may here add a note of its 
dimensions, viz. wing from carpal joint 16 inches, tarsus 3*5, 
middle toe s. u. 3. 
I have never examined a skeleton of this species ; but the 
considerable difference in size between the sexes, and the 
great prolongation of the middle toe, lead me to doubt whether 
Mr. Sharpe has taken a correct view in placing it among the 
Buzzards, instead of allowing it to remain -among the Hawks,
