* From Dr. Jerdon's forthcoming work on Indian Ornithology I quote 

 (with permission) the following : — " The Bhyri does not breed in this 

 country, nor ever, I believe, in the Himalayas, but migrates to the north 

 in April, and returns about the first week in October. Mr. Layard men- 

 tions the Peregrine as breeding in Ceylon in January, and Dr. Adams says 

 that he found the nest on a tree on the banks of the Indus, below Feroze- 

 pore ; but I imagine that in both cases an old Laggar {F.jiigger) has been 

 mistaken for the Bhyri." Mr. J. H. Gurney is of opinion (expressed in 

 epistola) that the true F. peregrinus, in addition to the F. calidus, will 

 prove to occur occasionally in India.

 tween Ceylon and Sumatra, about seventy miles from the Nicobar Islands.
