Falco babyloiiicus and Falco barbarus. 165 



The following are measurements which I have taken from 

 presumed females of F. babylonicus, the sex of which has not 

 been recorded ; these specimens (except where the reverse is 

 mentioned) are all adult and preserved in the British 

 Museum : —

I add^ for comparison, the following measurements of adult, 

 or nearly adult, specimens of Falco barbarus, the sex of which 

 has been recorded by the collectors. 



These measurements have been taken by myself from the 

 specimens in question, which have all been obtained in 

 Northern Africa ; but additional carefully sexed African 

 examples of F. barbarus are much to be desired, for the sake 

 of supplying a larger series for comparison than exists at 

 present.
