Mr. Gurney gives some very interesting notes on this species in the 

 Ibis, vol. V, 1875, pp. 356-7, which we reproduce here: — "As the 

 Leyden specimen, of which the measurements are given by Mr. Sharpe, 

 and that at Antwerp, of which the dimensions were recorded by Dr. 

 Sclater in 'The Ibis' for 1861, appear by their size to be both female 

 birds, I add the following particulars of the supposed male which is 

 preserved in Norwich : — wing from carpal joint 9.1 inches ; tarsus 2.1 ; 

 middle toe, s. u. 1.3 ; culmen from anterior margin of cere 5. It will 

 be seen by these measurements of the culmen and middle toe, that, 

 according to the rule given by Mr. Sharpe at p. 47 of his ' Catalogue,' 

 this species comes rather under his genus Accipiter than under that of 

 Astur ; its natural position appears to me to be intermediate between 

 the Asturine subgenus Lopliospizias and the Accipitrine subgenus Coop- 

 erastur, to which it was referred (and, on the whole, I think rightlv) bv 

 Bonaparte in the Eev. et Mag. de Zool. for 1854, p. 538."
