590 MESSRS SCLATER AND SALVIN ON [May '^.■^, 



Para, one example, killed in December 1849. 



The only description of this well-marked species is that given by 

 Von Pelzeln ; and we feel bound, therefore, to adopt his name for it, 

 in preference to either of Bonaparte's, which have no sufficient diag- 

 nosis attached to them. We have compared Mr. Wallace's speci- 

 men with Buteo kaupi of the British Museum (of which there are 

 two specimens in the collection) and find them identical.
