1875.] RAPTORIAL BIRDS OF INDIA. 17 
up to that date. The result is that I, or rather ornithologists gene- 
rally, have to acknowledge certain errors consequent on a limited 
knowledge of a most difficult group of birds. At the same time I 
am glad to be able to introduce several new species as occurring in 
the country to which my observations have ‘been confined, viz. the 
deltaic portion of the North-western Provinces, thus making (with 
the necessary corrections and additions) no less than 48 species of 
Raptores known to occur in this district. 
This is the number that have as yet come under my own observa- 
tion. But further investigation will doubtless enable me to add 
several more, such as Falco babylonicus, Haliaetus plumbeus, &c. 
Additions to former lists are indicated by an asterisk, *. 
1. VuLtur monacuus, Linn. 
All the specimens examined by me have alight fulvous nuchal patch, 
almost white ; but the authors of the ‘ Birds of Europe’ do not al- 
lude to this peculiarity in the Indian bird, nor is it shown in the 
plate. 
2. VuLTuR caALvus, Scop. 
On the 15th of July, 1872, my friend Mr. Spry took an egg, 
flushing the bird off her nest, which also contained an egg of Falco 
_ jugger. 
*3 bis. Gyps FULVESCENS, Hume. 
The large fulvous-coloured Vulture already alluded to I identify 
as belonging to this species, and not to G. himalayensis of the same 
author. 
5. Gyps BENGALENSIS, Gm. 
Last cold season I found a small colony of these Vultures breeding 
on a clump of high cocoa-nut palms (Cocos nucifera), whence I ob- 
tained four eggs. I have also lately taken three eggs from one nest, 
and two from another, but of course not the produce of the same 
birds. The tree on which these nests were built was the rendezvous 
of a large assemblage of these useful birds, which were attracted to 
this solitary tree by the carcass of one of the mail-cart horses which 
had died on the roadside. 
6. NEOPHRON GINGINIANUS, Lath. 
Captain Beagin, of H.M. 105th Regiment, has lately sent me a 
series of Neophrons from Aden, which appear to be referable to the 
African form N. perenopterus, Linn. ‘The skins are badly put up, 
and they are not sexed; so that the minute differences pointed out by 
Blyth+ cannot be compared with Indianexamples. The series com- 
prises both black-billed and black-clawed examples, which predomi- 
nate, as well as white ones, so that this one difference cannot seem- 
ingly hold good; but the corneous portion of the bill, as well as the 
claws, when black are certainly of a much deeper black in the Aden
