IISX OF DITJRN^AL BIRDS OF PRET. 



^ See note 5 on page 1 07. 



^ Since my Notes on F. pjiniciis were published I have been indebted to the kindness 

 of Loi-d Lilford for the opportunity of examining two adult Falcons, both of which I 

 think must be considered as females oi F.punkus, though one is a trifle larger, and the 

 other decidedly smaller than any other females of F. punicus that have come under my 

 notice. The following are the principal dimensions of these two Falcons : —

I may add that Lord Lilford also possesses a wing of an immature male of F. punicus, 

 taken from tjie nest on Madalena Island, off the coast of Sardinia, in May 1881, and 

 accidentally killed in the following October, which measures 11-50 inches. 



^ Here figured as '^ Faleo hahylonicus," which Mr. Anderson subsequently corrected. 



* Mr. Seebohm, at page 30 of his work on 'British Birds,' refers to F. babykmicus as 

 "probably the female" of F. barbarus; this surmise may, I think, be disproved by the 

 following summary of measurements taken by myself from eleven adult or nearly adult 

 specimens of F. babylo7ncus, presumably of both sexes : — • 



Wing 12-50 to 13-30 



Tarsus 1-90 to 2-10
