Birds that appear rather less adult have elongated white 

 shat't-stripes on the feathers of the side of the breast : in a 

 half-grown bird with the down still on the throat they are 

 larger and more evenly distributed over tlie whole of the 

 lower surface. 



Arboricola rufogularis, to which this bird is closely allied, 

 has not been recorded from farther east than the hills of the 

 Buroio-Chiuese border and in tiie south from the Muleyit 

 range in Tenasserim. 



We have compared this series with a specimen from 

 Toruputu Peak, Dafla Hills {Godwin- Austen)., and one from 

 Loi San Pa, South Shan States (^Binghani), and find our 

 birds to differ in the very much greater extent of white on 

 the throat and fore-neck and in the lesser extent of the 

 chestnut of the Hanks, which is paler in tint. 



2. Arboricola brunneipectus albigula, subsp. nov. (PI. XI.) 



Differs from A. b. brunneipectus * Tick., of Burma and 



Tenasserim, in having the forehead and superciliary stripes 



mingled white and buff and the throat pure white ; and 



from A. b. henrici f Oust., of Tonkin and northern Annam,
