of North-Eastern Africa. 
young bird, similar to Strickland's specimen (which came from 
Kordofan), shot by myself near Chart um in a Mimosa-forest, 
has been accurately compared with an old Abyssinian specimen 
of A. minullus , without any specific difference having been 
discovered. 
7. Accipiter minullus (Baud.). 
Rare, in thick bushes on the Blue Nile, in Western Abyssinia, 
on the Mareb. East-African specimens appear to form a very 
constant variety. 
8. Accipiter perspicillaris (Rupp.) (probably identical with 
A. eocilis, Temm.). 
Rare in Abyssina and on the Blue Nile. 
9. Accipiter unduliventris (Rupp.). 
Single specimens occur in the valleys of Simen, in Abyssinia 
(Rupp.). 
10. Accipiter nisus (Linn.). 
Frequent in Egypt during the winter, occasionally in Arabia, 
and along the Nile southwards to Kordofan and Sennaar.

A species of Buteo, closely allied to B. tachardus, is found 
singly in the regions situated within the rainy zone of North- 
Eastern Africa. I have called it Buteo minor. The bill is longer 
and more slender than in B. tachardus ; the tarsi are several lines 
longer, one-fourth or one-fifth of their length being covered 
with feathers; the third primary is the longest. The colours 
are subject to variations, as in B. tachardus and B. vulgaris; but 
the whole back and the covers of the wings in B. minor are di¬ 
stinguished by a very strong metallic violet-like splendour. It 
does not appear as if there were any other constant difference in 
the coloration of the three species named.
