yellowish beneath, and in liaving the under wing-coverts 

 and axillaries more tinged with verditer-green ; they are, 

 however, in very worn plumage. The colour of the mandibles 

 seems variable, as one of tiie above males and the female 

 have it clear wax-yellow, while in one of the Koh Lak males 

 it is also largely yellow.

The changes in the colour of the bill appear to be some- 

 what complicated in this species. Quite young birds of 

 both sexes have both mandibles orange-red ; this changes 

 to black in both mandibles in the adult female and also in 

 the semi-adult male, which finally assumes a blood-red 

 upper mandible with a yellow tip when fully adult.
