' Since writing the Notes above referred to, I have, through the kindness of Captain 

 Wardlaw Ramsay, had an opportunity of measuring some additional specimens of this 

 species, with the following result : — 



Middle 

 Wing. Tarsus. toe 6-. u. 



in. in. in. 



Luzon, J 4 0-80 0-80 



c5' 415 0-75 0-75 



9 4-60 0-95 0-80 



5 4-20 0-90 080 



2 4-55 0-85 0-80 



Zamboanga, c^ 4-65 0-85 080 



2 4-65 0-90 0-85 



The supposed male from Zamboanga was sexed by the collector, Mr. Everett ; but in 

 this instance I doubt the correctness of his diagnosis. 



2 Here figured under the title of '' Falco gironnieri." 



^ This plate is inscribed " Hypofriorchis castanonofus ;" Sir A. Smith's "Falco semi- 

 torquatus."
