Dr. P. L. Sclater on the Birds of the Zambesi Begion. 303 



undertaken to insert in his list some few species that are in 

 Dr. Dickinson's series^ but not in his own. 



Dr. Dickinson's collection contains examples of seventeen 

 species of Falconida and five of Strigida. To render the list of 

 Zambesian Accipitres as complete as possible, I may mention 

 that Dr. Kirk's collection contains, besides Accipitres, examples 

 of the following species, which are not in Dr. Dickinson's 

 collection : — 



Halia'etus vocifer (Daud.). 



Circus ranivorus (Daud.). 



Erythropus vesper tinus (Linn.). 



Scotopelia peli, Bp. 



Athene capensis, Smith. 



Also, that though neither Dr. Kirk nor Dr. Dickinson obtained 

 any specimens of the family Vulturidse, it is certain that there 

 are at least three or four species of this family to be found there ; 

 namely, Vultur auricularis, Neophron percnopterus, N. pileatus, 

 Gyps fulvus, and probably Vultur occipitalis and Gyps rueppellii. 



In the following list, where the contrary is not stated, I have 

 used the nomenclature and arrangement of Mr. G. R. Gray's 

 List of the specimens of Accipitres in the British Museum. 



1. Aquila pennata (Gm.). 



Chibisa. One example. " Iris vandyke-brown ; cere and toes 

 lemon." 



2. Spizaetus occipitalis (Daud.). 



Two examples. Magomero and Chibisa. " Iris bright yel- 

 low; cere pale yellow; bill bluish, tip black; toes light yellow, 

 claws black." 



3. Spizaetus spilogaster, DuBus.
