We thus have these differences at the greatest extremes 

 of its range: a bird in the Punjab with a wing of 83'2 and 

 another in Ceylon with one of 78*0, i. e. a difference of ouly 

 5"2 mm., but from -the north-west 12 birds average only 

 79 6 mm., which is exactly the same as those from Travan- 

 core. Under these circumstances it is impossible to make 

 any geographical races on the ground of size. There is, 

 however, one race which is easily distinguishable on account 

 of the much bigger bill, which, measured from nostril to tip, 

 averages over 17 ram. as against well under 14 mm. for 

 the rest. 



We have, therefore : — 



(1) Xantholaema hsemacephala haemacephala.
