The specimens from Patani are slightly smaller than birds from 

 farther north in the Peninsula. 



Specimens from Cochinchina and south Annam appear to belong 

 with the birds from southeastern Siam. 



Treron curvirostra nipalensis has a wide range, occurring from 

 Nepal south through Assam and Burma to eastern Bengal, Tenasserim, 

 the northern part of Peninsular Siam, all Siam proper, Cochincliina, 

 Cambodia, Laos, and Annam. Other forms occur in the Philippines, 

 Borneo, Java, Sumatra, and the chain of islands off the west coast of
