298 Mr. T. Ayres on the Ornithology of Transvaal. 
in Natal; but as be has not recorded it from Transvaal, 
I may take this opportunity of mentioning that an adult 
specimen sent from Transvaal to Mr. Whitely, of Woolwich, 
has lately been added to the Norwich Museum. 
This, however, is not the most northern locality in which 
this species is found. There is, in the Norwich Museum, an 
adult example from the district of the Zambesi; and Captain 
Shelley possesses another obtained at Rabbai, near Mombasa, 
as recorded by him in the P. Z. S. 1881, p. 562. 
I have examined several adults of this species, and in all of 
them I have observed a peculiarity which is not noticed in 
Mr. Sharpe's description of this Hawk, viz. a patch of dark 
rufous feathers in the centre of the upper part of the nape, 
of a somewhat square shape, and measuring from an inch to 
an inch and a half in vertical, and the same in transverse 
diameter. 
I have only been able to examine three adults of the allied 
African species, B. cuculoides, in all of which there was 
merely an extremely slight trace of rufous on the nape, in 
place of the conspicuous patch exhibited by the adults of B. 
verreauxi. I may add that there appears to be a noteworthy 
difference in the colouring of the soft parts of these two 
nearly allied species. Mr. Ayres, referring to an adult 
female of B. verreauxi in f The Ibis 9 for 1864, p. 356, 
describes the iris and cere as “ light yellow" and the tarsi 
and feet as “ yellow ;" whilst Mr. J. Biittikofer states that, in 
a male of B. cuculoides obtained by him in Liberia, the iris 
was “red" and the “cere and feet orange" (vide ( Notes 
from the Leyden Museum/ vol. vii. p. 156). 
The most striking distinction between the two African 
species of Baza is, however, that of the colouring of the 
under wing-coverts described by Mr. Sharpe in the British 
Museum Catalogue, vol. i. p. 351.—J. H. G.] 
[I am desirous to take this opportunity of correcting an 
error which I made in f The Ibis/ 1885, p. 349. I there 
referred to certain measurements of Herodias intermedia as 
“ given by Mr. Sharpe;" but I ought to have said “ given 
by Mr. Ayres."—J. H. G.J
