90 Mr. LEADBEATER on some new Species of Birds 
scription of a species I have received from the Cape of Good 
Hope. "This bird, although it does not exactly accord with the 
description of the bird originally brought from the same place 
by Dr. Sparmann, may yet be the female, or a variety of that 
species ; the descriptions of it being very vague and confused, 
and the identity of the species being much in doubt. 
5. Le VAILLANTII. L. olivaceo-brunneus, subtüs albidus, gul 
pectoreque flavo-variegatis ; rectricibus duabus mediis fusco- 
— brunneis, ceteris albis fusco-brunneo notatis. 
Tectrices superiores flavo leviter marginate, inferiores albide. 
Remiges olivaceo-brunnec margine interno pallidiore, sub- 
tùs fusce interne albido marginate. Rectrices prima et 
secunda albæ apice brunneo, tertia alba apice basique 
brunneis, quarta et quinta brunnee margine interno albo, 
duz medic brunnez. Rostrum obscure brunneum, sub- 
breve, gonyde subfortiter angulata. Pedes nigri, unguibus 
pallidioribus. | ; 
Longitudo corporis, 71; ale a carpo ad remigem tertiam, 41, ; 
caude 34, ; rostri ad rictum 12, ad frontem 1; tarsi 13. 
This bird has at first sight some appearance of the J. albi- 
collis* of M. Temminck; and on a. superficial examination 
might be pronounced either the female or the young male 
of that species. But the bill will be found to be decidedly 
distinct; being shorter and stronger, and having a much more 
acutely angulated gonys than the bill of that bird. 
I. Le Vaillantii also is of less dimensions than the former 
bird; and the disposition of the colours, as may be seen by the 
above descriptions, is different in both. I have named the spe- 
* The male and female of this species had been originally described and named in 
this paper; but as the species has been figured by M. Temminck subsequently to the 
reading of the paper, I adopt his name,—N ov. 29, 1828.
