Obs. Tliis bird \vould belong to M. Lesson's genus Lophotes; but

 The form is somewhat aUied to Pemis.

Obs. This species is very nearly allied to the 3Iilvus ater of Eu- 

 rope : the circumstance of nearly the \vhole of the Fauna of Au- 

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

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

 ference is in its being some\vhat smaller in size.
