THE BIRDS OF SOUTH-WEST AND PENINSULAR SIAM 321 



Probably common in grassy places throughout the country. 



There is no evidence that birds from Arracan north to Assam 

 (F. rufescens), and those from N. Tenasserim south through the 

 Malay^ Peninsula (F. beavani), have any constant differences. F. 

 'poliocephala Anderson, from Kumaon, appears to belong to a differ- 

 ent section of the genus.
