BIRDS FROM SIAM AND THE MALAY PENINSULA 509 



The Peninsular Siam series compared with A. a. wffinis of Java is 

 more greenish (yellowish citrine) rather than old gold above, and 

 below it is more yellowish, less grayish, with the streaks on the 

 throat and chest finer and less sharply defined. 



The two immature males from Sichol are nearly full grown. They 

 resemble the adult, except that the throat and chest are without 

 streaks and the bill is shorter. 



A. a. modesta ranges from Sumatra and the Malay States north- 

 ward through Peninsular Siam to Tenasserim. 



Ogilvie-Grant ®^ has recorded it from Patani; Robinson ®^ from Kao 

 Nawng, 3,500 feet, Bandon; Robinson and Kloss ^* from Kao Luang, 

 Nakon Sritamarat, 2,000 feet, and later ^° from Tasan, Chumporn.

One male. Waterfall, Trang, August 25, 1933. 



Dr. W. L. Abbott took three females in Trang, January 27-Febru- 

 ary 24, 1899. He gives the soft parts as: Iris dark brown; bill black; 

 feet dull black, blackish brown, or very dark fleshy brown. 



Robinson and Kloss ^^ report taking four males in Chong, Trang, and 

 say that these are the northernmost on record. The same authors ^^ 

 say that it is quite common in Trang but decidedly rare throughout 

 the rest of the Peninsula. 



I have not examined any specimens from Sumatra or Borneo. 



The species ranges from Trang, Peninsular Siam, south to the 

 Malay States, Sumatra, and Borneo.
