" Iris crimson, eyelids dull red ; bill plumbeous blue, base 

 of culmen and nostrils plum-red; feet plum-coloured. 



"Very common on all the islands visited, where the loud 

 booming note was heard all day long.'' — C. B. K. 



The dimensions of this series, compared with that of 

 specimens from the Malay Peninsula, are rather small ; 

 the bird from Koh Klum (wing 209 mm.) is especially so 

 and is more richly coloured^ the top of the head being more 

 vinaceous.

" Orbital skin grey, the edges of the eyelids plum-colour; 

 bill coral-red, base plum-coloured j feet livid plum.*' — 

 C. B. K. 



Stuart Baker's figure of the female is decidedly in- 

 accurate, as the forehead is never so devoid of grey as is 

 shown in the drawing. 



* The two islands of Koh Mehsi, West and East, are shown respec- 

 tively on Admiralty charts as "He du Pic " and " Le Chameau," but I 

 have preferred to use the names by which they are known locally.
