are ferroginous, but some of them are very slightly and 
irregularly edged with blackish brown on the outer webs 
towards the tips. 
The male specimen differs from the female in having the 
crown of the head of a somewhat darker grey, and also in 
the rectrices (other than the central pair) showing more 
blackish brown on the outer webs, which is especially the 
case with the external pair.—J. H. G.] . 
Pycnonotus nigricans (Vieill.). Brunoir Bulbul. 
Male, shot 11th January, at Potchefstroom. Total length 
8 inches, bill (from gape) tarsus 1, wing 3|, tail 3f. 
Irides bright reddish hazel; eyelids orange; bill black; 
tarsi and feet black. Contents of stomach, grapes. 
Female, shot 18th May, at Potchefstroom. Irides bright 
reddish hazel; eyelids yellow; bill black; tarsi and feet 
very dark ash-colour, nearly black. 
[The plumage of these specimens agrees with the descrip¬ 
tion given under the head of P. nigricans in the first edition 
of Mr. Layard^s work. In the female killed on the I8th of 
May, which had nearly moulted, the head is decidedly black; 
in the male killed on the 11th of January the plumage is 
worn and faded, and the head, though black, is slightly tinged 
with brown; but in neither specimen does the colour of the 
head agree with the description given in the second edition 
of Mr. Lavard^s book under the head of P. capensis .—
