Although specimens have been examined from all the islands known 

 to be inhabited by this species, adult males from only two of them, 

 James and Charles, have been seen by me.' These do not differ so far 

 as I can discover, and I am unable to detect any constant dilfeiences 

 between the females and immature birds from the several islands.
