 southern Philippine islands.

An example of each of the two following species of Falcons, said to have been 

 obtained in the Philippines, is contained in the Museum at Norwich. Although there 

 is nothing absolutely impossible in either, or both, of these species occurring in the 

 archipelago, I refrain from treating them as authentically ascertained Philippine species, 

 the evidence in favour of their Philippine origin requiring confirmation.

Hah. Luzon {Meyer). 



Kaup in 1850 (Contrib. Orn. 52) united H. erythrogenys with //. sericeus, applying 

 Vigors's title to the male, and that of Kittlitz to the female. Dr. v. Martens (J. f. O. 

 1866, p. 9) suggested that the two titles belonged to one and the same bird. Mr. J. 

 H. Gurney writes to me that he considers //. erythrogenys, Vigors, to be the female 

 (and probably the young male also) of H. sericeus (Kittlitz) ; also that M. Jules 



' Striokland (Om. Syn. p. 104) gives 1809 as the date. This must be an error ; for Kittlitz first obtained 

 the pair he described from in the year 1S29, whoa vdih the Russian corvette ' Senjavin ' at Manilla.
