1900; three males, Trcngganu, 1900 (Tanjong, Dungun, September 

 21; Dungun River, September 24; Kemamun River, October 1). 

 He gives the soft parts as: Iris yellowish brown or pale reddish brown;, 

 bill black; feet pale orange fleshy. In the young male taken at 

 Tanjong Dungun, Trengganu, September 21, the soft parts are given 

 as: Iris whitish brown; bill yellow horn, culmen brown; feet brownish 



yellow. 



With only two males from central Siam to compare with Peninsular 

 specimens it is impossible to tell whether the southern birds are the 

 same or not. In plumage there is apparently no material difference, 

 but the bills of the two northern males seem to be somewhat shorter 

 and less heavy. 



In some specimens the superciliary streak is well-marked; in others 

 it seems to be altogether lacking. To this I can offer no explanation. 



A young male taken by Dr. Smith at Nakon Sritamarat, September 

 24, and a young male taken by Dr. Abbott at Tanjong Dungun, 

 Trengganu, September 21, differ from the adult male as follows: 

 Pileum and upper parts buffy citrine, inclining to olive on the head; 

 tail with a grayish tinge along the shaft, dusky subterminally, and 

 tipped with light yellow; superciliary, interrupted eye ring, cheeks, 

 and lower parts amber-yellow. The two birds are about adult size. 



This form extends from Nepal east to Assam, eastern Bengal, 

 Burma, Siam, and the Malay Peninsula to Singapore, Sumatra, Java, 

 and Indo-China. It is probably resident where found. 



Williamson ^^ reports it from Muek Lek, eastern Siam. Herbert ^^ 

 found it breeding around Bangkok and Samkok in July and collected 

 eggs, which he describes. Deignan ^^ noted a few at Chiengmai in 

 February 1931. 



Since the above was written, Chasen 2* has recognized the Malay 

 Peninsula, Sumatra, and Java populations of this species as P. j. 

 raffiesi Twecddalc.^^ It is most likely that all the above Siamese 

 records belong to it, except those from the north.
