Obs. Tiiis bird would belong to M. Lesson's genus Lophotes; but 

 that term having been previously employed, I have been induced to 

 adopt the generic title proposed by Mr. J. E. Gray in its stead. 

 The form is somewhat alliecl to Pernis.

 Hab, in Australia. 



Obs. This species is very nearly allied to the Milvus ater of Eu- 

 rope : the circumstance of nearly the whole of the Fauna of Au- 

 stralia being distinct from those of all other parts of the world has 

 induced me to separate it specifically from that bird ; the chief dif- 

 ference is in its being somewhat smaller in size.
