be scarce hereabouts, as Mr. Pearse, who has an extensive 

 practical acquaintance with the ornithology of the district, 

 was not acquainted with it, and had not previously met with 

 specimens. 



IX. — Notes on a ' Catalogue of the Accipitres in the British 

 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 Gould^s ' 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,
