This bird may probably be found in our area : it i.s more 



likely to be D. c. leucogenys (Blyth), from Pegu, than the typical 



Chinese form. Salvadori has given the name Dryonastes propinquus 



to a Tenasserim bird (Ann. Mus. Civ. Gen. (6) 1915, p. 6): that may 



also refer to the present one.

All these specimens are quite adult and have a broad grey 

 collar separating the maroon of the mantle from the white of the 

 head. They also have the centre of the abdomen white, but vary much 

 in the amount of chocolate brown on the flanks which is very pro- 

 nounced in the bird from Hat Sanuk, and a pair from Koh Lak.
