298 Mr. T. Ayres o)i the Ornithology of Transvaal. 



in Natal ; but as he 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. Sharpens 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. verreauxl in ' The Ibis ' 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 ' 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
