444 Mr. J. H. Gnruey's Notes on 



also in Kashmir (whence was obtained a specimen now pre- 

 served in the Norwich Museum), in Nepaul (as evidenced by 

 two examples in the British Museum), and in North-eastern 

 Cachar"^. 



In all the Falcons of the genus Gennaia, as above specified, 

 the two central feathers of the tail are whole-coloured and 

 unbarred in birds of the first year, and, in the case of G. 

 juggur, in most adults also ; but in a few adults of this species 

 indistinct transverse bars are perceptible. An old Indian male 

 in the Norwich Museum shows nine such indistinct broad 

 dark cross bars on these feathers, separated by narrow and 

 rather ill-defined whitish interspaces. 



The comparatively restricted range of G. juggur offers a 

 remarkable contrast to the vast area comprised in that of 

 its congener G. saker, extending ft-om Western Morocco f 

 to North-eastern China. 



It has, however, been held by some eminent ornithologists, 

 and notably by the late Mr. Jerdon J, by Mr. Hume §, by Mr. 

 W. E. Brooks II, and by Lieut.-Col. Prjevalsky^, that two 

 distinct species have been confounded under the specific name 

 of " Saker." 



If this be the fact, the scarcer of the two phases of colora- 

 tion — that in which the mantle and tail are crossed by alter- 

 nate bands of dark brown and rufous, and which has been 

 figured in Wolf's Zoological Sketches, vol. i. pi. 33, in 

 Dresser's ' Birds of Europe,' pi. 377**, and in Henderson 

 and Hume's ' Lahore to Yarkand,' part 2, pi. i., should bear

t Mr. Howard Saunders recently informed me that he examined, a few 

 months since, a living- specimen of G, saker, which had been imported by 

 Mr. Castang from Mogador. This specimen subsequently passed into the 

 possession of Lord Lilford, who agrees with Mr. Saunders in referring it 

 to this species,

** The figure in the ' Zoological Sketches' and that in tlie 'Birds of 

 Em-ope ' were both drawn by Mr. Wolf from a specimen brought from 

 Tarsus, which is now preserved in the Norwich Museum.
