ANTHOCICHLA PHAYRH PHAYRH Blyth 



Anthocichla phayrii Blyth, Journ. Asiat. Soc. Bengal, vol. 31, p. 343, 1862 (Toung- 

 hoo, Burma). 



One male, Pang Sok, eastern Siam, August 19, 1926; one male, and 

 two females, Kao Pae Pan Nam, Lamsak, February 18-19, 1934. 



One of the females from Kao Pae Pan Nam is immature. It is 

 about full grown. The black head markings of the adult are replaced 

 by brown like the back; the chest and sides are spotted or barred with 

 black; the back is darker brown than the adult, but the lower parts 

 are lighter. 



I have examined no birds from northern Siam, but two males from 

 Klong Menao, southeastern Siam, do not seem to differ appreciably. 



Gyldenstolpe ^^ records it from Pak Koh and Khun Tan, northern 

 Siam; Robinson ^^ from Ok Yam, Franco-Siamese boundary, and 

 Klong Menao, southeastern Siam; de Schauensee ^* also took a female 

 at Khun Tan at about 3,500 feet, and found it not so dark as specimens 

 from Bolovens, Laos. 



The form ranges from Burma east of Sittoung River, Tenasserim, 

 and the Shan States, to northern, eastern, and southeastern Siam 

 and southern Laos.
