X. p. 178; Gurney, Ihis, 1882, p. 291. 
Description. — Male and female. Similar in general character of plumage 
to F. peregrinus, but differs chiefly in having the crown^ nape_, upper back^ 
wing-coverts and moustachial stripes deep blacky and the lower surface 
deep rufous with very few marks, these being chiefly on the thighs_, under 
tail-coverts and sides of the body. 
The young are blackish above^ the feathers more or less margined with 
rufous_, and the lower surface rich tawny streaked with black. 
The dimensions do not differ appreciably from those of F, peregrinus. 
The Indian Peregrine was sent to Lord Tweeddale by Colonel Lloyd 
many years ago. The specimen in question is said to have been shot at 
Tonghoo^ and there is no other instance known of its having occurred in 
Burmah. 
It is met with throughout the greater part of the Indian peninsula from 
the Himalayas to Ceylon. 
This bird is hardly more than a race of the Peregrine. Another race is 
F. atriceps from tlie north-west of India^ the chief characteristic of which 
lies in the moustachial band, which is not separated from the black of the 
head as in F. peregrinus and F. peregrinator.
