ON FALCO BABYLONICUS AND FALCO BARBARUS. 483 
With regard to the western range of F. babylonicus, I may 
also refer to the translation by Mr. Dresser in “ The Ibis,” 
1875, pp. 106, 107, of some valuable notes by the late Prof. 
Severtzotf as to the breeding of this species in Turkestan ; 
but the supposed “ young male” from Chimkent there men- 
tioned would seem, by its wing-measurement, either to have 
been incorrectly sexed, ory to be an immature example of 
some allied species. In the same article Severtzoff records 
@ specimen taken in Persia and two “taken from the nest 
on an island in the Volga.” 
The following measurements have been taken by myself 
from Falcons which I believe to be referable to F. babylonicus, 
and which have been marked as males by the collectors ; they 
are all adult birds, and all preserved in the British Museum 
at South Kensington, except where I have mentioned the 
contrary :—

The subjoined measurements I have taken from specimens 
in the British Museum, which I believe to be males of 
F. babylonicus, but of which the sex was not recorded by the 
collectors :—

and my own, see “ The Ibis,” 1882, p. 311 (note). Sra
