Robinson and EQoss " report a male from Tasan, Chumporn, Penin- 

 sular Siam, and go on to say that the species is of considerable rarity 

 in the Malay Peninsula. It is probably not uncommon in Trang, as 

 Dr. Abbott secured the above specimens in three different years in 

 the Province. 



The female from Prahmon differs from the other female (and the 

 males) in having the chest deep olive-buff and the throat colonial 

 buff. The other female has the throat and chest pale lemon-yellow, 

 with a deep olive-buff" undertone. In the males the yellow of the 

 chest and throat and the olive-buff undertone are somewhat deeper in 

 color. In two of the males the deep olive-buff undertone is nearly 

 absent altogether. 



The four males measure: Wing, 72.5-83 (77.6); tail, 44-45 (44.4); 

 culmen, 32-35 (33.6) mm. The two females: Wing, 64-66; tail, 

 37-38.5; culmen, 30-32 mm. 



A male from the Siak River, eastern Sumatra, has a deeper cast to 

 the chest, grayish rather than olive-buff"; it has the appearance of not 

 being fully adult. A male and unsexed specimen from Borneo do not 

 seem to differ appreciably from Peninsular Siam birds. 



The species ranges from northern Peninsular Siam south to the 

 Malay States, Sumatra, and Borneo.
