Tlie late Pi'ince Charles Bonaparte, who had an unhappy trick of publishing new names 

 for birds without any descriptions attached to them, or with diagnoses so short as to leave them 

 practicably unrecognizable, appears to have twice essayed to bestow a specific designation upon 

 the present Buzzard. In his " Conspectus," " Leucopternis Kuhli''' characterized, as " similis 

 prcecedenti^ (i.e. L. melanopi) sed capite nigricante.^ unguihiis alhis" is probably intended for the 

 present bird, as we know of no other species to which the phrase would be suitable. In some 

 cursory notes upon the Rapacious Birds, contributed to the Revue de Zoologie for 1850, a new 

 species is again somewhat similarly described* as " Leucopternis Kaupi." But in this case we 

 have been able positively to identify the bird, by reference to the marked specimens of it in the 

 British Museum. 



We cannot, however, think that it would be right to supersede in favour of either of these 

 names, Herr von Pelzeln's term supereiliaris ; which, although published subsequently, is 

 accompanied by a full and excellent description. 



Natterer, upon whose specimens v. Pelzeln founds his species, obtained three examples of 

 this Buzzard in Northern Brazil ; at Borba on the Madeira, and at Para. At the latter locality 

 Mr. Wallace also procured a single specimen, which he has kindly loaned to us for the purpose 

 of the present work. Our figure represents this bird at a reduction of two-thuxls of its natural 

 size.
