LIST OF DIURNAL BIRDS OF PREY.

1 The peculiarities of coloration and marking which Mr. Blanford observed in his 

 Abyssinian .specimens (vide Geol. and Zool. of Abyssinia, p. 292), and which I formerly 

 agreed with him in considering to be indicative of the specific validity of M. niloticus 

 (Sund.), I now think are more probably in the nature of individual variations (perhaps 

 contingent upon age) than in that of specific distinctions of a constant and stable cha- 

 racter. Levaillant figures a South-African specimen under the name of " Le Gabar." 



^ In my Notes I have treated the genus as most nearly allied to Asfiirina ; but I am 

 now of opinion that it is even more closely related to Melicmx. See my remarks in 

 P. Z. S. 1878, p. 791 ; coiif. Garrud, P.Z. S.*1873, pp. 466, mi.
