BIRDS FROM SIAM AND THE MALAY PENINSULA 517 



There seems little if any difference in size between the northern 

 and southern Malay Peninsular forms. Eleven males from Rhio 

 Archipelago (1), Singapore (1), Patani (2), and Trang (7) measure: 

 Wing, 46-52 (48.6); tail, 19.5-23.5 (21.8); culmen, 10.5-11 (10.8) 

 mm. Four males from Mergui Archipelago (3) and Bandon, Penin- 

 sular Siam (1): Wing, 46-52 (49.7); tail, 20.5-24 (22.6); culmen, 

 10-11 (10.5) mm. 



Stuart Baker ^* says this form occurs in Assam in a restricted area 

 (Lakhimpur) and then does not occur again until the Karen Hills 

 and Pegu, Burma, are reached; thence it occurs to southern Tenas- 

 serim, and Peninsular Siam as far as Bandon and Nakon Sritamarat 

 on the eastern coast and Ghirbi and Junkseylon (Puket) on the 

 western coast. The last two localities are cited on the authority of 

 Robinson and Kloss.^*

One male, Kao Seming, Krat, October 10, 1928. 



This specimen is much brighter above than the Peninsular race 

 (chrysorrhaeum); below the streaks are finer, the throat whiter, and 

 the under tail coverts a deeper yellow. 



The form ranges from latitude 10° N. in Peninsular Siam northward 

 through Siam to Burma and eastward to Cochinchina, Annam, and 

 Tonkin.
