Type locality. Mi-Nam-Kabren, Siam. Friar 
Habitat. The whole of Burma, Siam, the Chin, Kachin, 
and Shan Hills, extending into Eastern Assam as far as 
Tezpur on the north and through Cachar, Sylhet, Chittagong, 
Manipur, and the Looshai Hills on the south, whilst it is 
also found on the ranges south of the Brahmapootra in 
Naogang, Naga Hills, Sibsagur, and Lahkimpur. It is also 
found in Hainan, and probably the intervening country. 
I include under this name all those birds which have no 
barring on the chin, throat, and upper breast of the adult 
female. As with all species which are represented by geo- 
graphical races, somewhat intermediate forms may be met 
with, but these are extremely rare in the present instance, 
except in the central portion of Northern Assam. It is 
interesting to note also that in this species the Brahmapootra 
does not form the dividing line between the races, as is so 
often the case.
