Mr. Butler was, we believe, the first to point out that the 

 black Hawk known as Melierax niger (Yieill.) was in all 

 probability only a melanism of this species. W^e believe 

 this to be undoubtedly the case, but to Avhat degree the 

 l)lack form is '* fixed " we have no idea. Mr. G. F. Archer, 

 C.iM.G., H.M.'s Commissioner of Somaliland, recently 

 wrote to Colonel Stephenson Clarke, who had asked him 

 to make a note of this point, that he had found black and 

 grey nestlings in the same nest.
