482 ON FALCO BABYLONICUS AND FALCO BARBARUS. 
being that the true F. barbarus does not extend its range so 
far eastward as India. 
Falco babylonicus, on the contrary, appears to be a regular 
winter visitor to Northern India, and especially to the north- 
western portions of that country. 
Of the Indian examples of this Falcon that I have examined 
five are recorded as having been obtained in November, six in 
December, eight in January, two in February, and two in 
March, of which last-named specimens one was an immature 
male, shot by Col. E. A. Butler at Hyderabad, in Sind, on 9th 
March, 1878, and the other an immature female, obtained at 
Peshawur on 3lst March, 1869. The earliest autumnal 
example in the series is an adult male shot by Mr. Doig at 
Ahmedabad, Guzerat, on 5th November, 1885. 
The following dates are recorded of specimens of Falco 
babylonicus collected beyond the Indian frontier and now 
preserved in the British Museum: An adult female killed 
near Kelat in October, 1876; an adult female obtained by 
Sir O. St. John at Kandahar, 14th February, 1871; an adult 
female obtained at Samarcand, 5th March; an adult female 
purchased by Dr. Scully at Yarkand, 6th March, 1875; an 
immature male obtained by Dr. Scully at Gulgun Shah, 
Eastern Turkestan, 27th August, 1875. The last and two 
young females (one from Kashgar, marked 13th December, 
1874, and the other from Yarkand, marked 26th February, 
1875) were apparently procured alive by Dr. Scully, probably 
having been brought up from the nest; and Dr. Scully, re- 
ferring to these specimens in “Stray Feathers” for 1876, 
p. 118 (under the name of F. barbarus), remarks : “This Falcon 
is said to inhabit the hills of Kizil-tagh and Kugiar, and to 
breed there in summer.” 
The most western Asiatic specimen of F. babylonicus that 
I have seen is the female in change from immature to adult 
dress, which was procured long ago in Babylonia by Com- 
mander Jones, and which suggested the specific name that I 
subsequently proposed for this Falcon; but it is probable 
that Falco babylonicus is also sometimes found, though very 
rarely, so far west as North-eastern Africa The Norwich 
Museum contains an adult female purchased from M. Par- 
zudaki, of Paris, who asserted that it was obtained in Abys- 
sinia ; and I am also now disposed to think that the Nubian 
Falcon in the British Museum, which I referred (P. Z.5., 
1878, p. 2) to F. barbarus, is in reality a male in the second 
year’s plumage of F’. babylonicus. *
