respective species would probably be found to have connecting 
links in intermediate species, the slight variations in size 
and color being such as might reasonably be ascribed to 
climatic causes. 
Fulco babylonicus is another bird that ought not, perhaps, 
to have been included in my former list. In the days 
when Captain (now Colonel) Irby wrote there was—and still 
is—much diversity of opinion as to the changes which 
Falcons generally undergo in plumage, and the specimen which 
he got at Barabanki (it does not appear to have been 
preserved) may have been nothing more than the “Shahin ” 
in a certain phase of plumage. At any rate I have tried in 
vain for a specimen that would satisfy me that it was the true 
babylonicus, though I have a specimen of what I consider to 
be an adult “Shahin” that might pass muster for Gurney’s 
Falcon so far as description goes. Another bird, one from 
Southern India, is so different in coloration as to lead to the be- 
lief that from youth to decrepit age the “ Shahin” must undergo 
many changes in plumage, and that, in one or more of these 
changes, it may possibly resemble, if it is not, babylonicus. 
The Shahin, it should be noted, is not quite so rare as my 
former paper would lead one to suppose. It is indeed about 
as common as the Peregrine during the cold weather, the two 
being often found together by the side of some favorite 
jhil. I know of one such favorite resort where eight or ten of 
these Falcons constantly reside in the cold weather. One day 
I took it into my head to “go for them.” The first I shot 
was a Peregrine, the second a “Shahin” (the adult above 
alluded to); the third and remainder are, I hope, living still, 
having given me a wide berth when they saw what I was 
up to. They had been living for the most part on the 
Rose-ringed Paroquets, the ground beneath the trees they 
frequented (each couple appeared to have their own special 
tree) being literally covered with the remains of these birds. 
The occurrence of either the Common or Blue-winged Teal 
{1 was unable to make out which) on the plains on the 2nd 
of May is worth recording. While travelling by train on that 
date I noticed a flock of at least 50 on a jhil just outside 
of Bareilly station. 
The following is alist of the spieces—23 in number—that 
have now to be added to those included in my paper on 
the “ Birds of the Lucknow Civil Division.” It is difficult 
to say how many more will have to be added before the 
list is absolutely complete; but I think we may safely assume 
that not more than 350 species occur in the division, of which 
337 have now been accounted for—not hastily, but during 
and after many years of careful and persevering research,
