The nearest ally of this Buzzard seems to be Leucopternis scotoptera (Max.), which is well 

 figured in Temminck's Planche Coloriee, No. 427, under the name Faloo lacernulatus. The 

 present species has much the same general coloration as the latter, but may be immediately 

 distinguished by its larger size, and by having the whole of the apical portion of the tail pure 

 white without any black cross-band. 



Our figure of this bird, which is half the natural size, is taken from a specimen in the 

 collection of Messrs. Salvin and Godman, purchased of Verreaux. It is mai'ked " Brazil" and 

 was in all probability obtained in the vicinity of Rio. 



July, 1868.
