The above measui'ements show that this species is very variable when adult 

 even after making allowance for seasonal changes. Average size: wing 148.8 mm, 

 tail 259.8, bill from nostril 19. 



The average size of the southern form is (from only 4 adults) wing 153.5 mm, 

 tail 279, bill from nostril 18.6; it is evidently rather larger, apparently with a 

 similar bill. 



Remark. The bird seems to moult in ApiH; specimen b is getting a fresh tail.
