128 Mr. J. H. Gurney on additional species of Birds 
colouring Trachyphonus margaritatus, but is distinguishable by 
its plumage, particularly of the head, in which the elastic horn¬ 
like structure of the feathers is still more developed. The face is 
fiery yellow, and, with the exception of the chin, on the point of 
each feather is a shining steel-black metallic spot. The roots of 
the entire pileus and the centre of the throat are of the same 
colour ; the neck is whitish, having in general before the point 
of each feather a broad black speck. The scapularies and 
wings are speckled with white on a smoky-brown ground; but 
these specks are not quite at the edge of the feathers, as in 
T. margaritatus; they exist on the wings and greater wing- 
coverts, but are never found on the inner barbs ; the wings are 
spotted with bright yellow; the back and tail-coverts are greyish 
green, with indistinct smoky-grey marks and small lanceolate 
spots. The under wing-coverts are whitish towards the roots, 
like the inner surface of the remiges . The under-side is bright 
greenish yellow, with little lanceolate black points to each feather; 
the lower tail-coverts deep red. The tail is exactly like that of 
T. margaritatus, only the spots here are yellow. Also in this new 
species the cross-band which T. margaritatus has on its breast is 
missing. 
Length 6 in .; beak from gape 10 lin.; wings 2 in. 8 lin.; 
tail 2 in. 10 lin.; tarsus 106 lin. 
The breeding and food of this bird are the same as those of 
P. diadematus. In its habits it is as sociable as T. margaritatus . 
XII.— On some additional Species of Birds received in Collections 
from Natal. By John Henry Gurney, M.P., F.Z.S. 
I beg leave to communicate for insertion in ‘ The Ibis 3 a short 
additional list of Natal birds, numbered consecutively to those 
published in my last paper on this subject (‘ Ibis/ 1860, 
/ pp. 203-221). 
The birds and the notes included in the present list were 
received by me from Mr. Thomas Ayres, of D^Urban, except 
where I have specified the contrary. The specimens not sent 
by Mr. Ayres have been selected from two collections received 
from Natal by Mr. S. Stevens, of Bloomsbury Street, London.
