Four males, Muang Kanbiiri, April 7, and September 10, 11, 1928; 

 one immature female and one immature unsexed. Bo Ploi, Kanburi, 

 September 7, 1928, and September 26, 1929; one female, Mekhan, 

 February 1, 1932. 



This series is lighter in color both above and below when compared 

 with a series from eastern Siam. There are a number of specimens 

 from Tenasserim in the United States National Museum, but they 

 are all immature birds not suitable for comparison. No material for 

 comparison has been available from Burma, so I am following the 

 original describer in placing the above series. 



There seems to be little difference in size between the series from 

 western and northern Siam and that from eastern Siam. Four males 

 and one female from western (4) and northern (1) Siam measure: 

 Wing, 145-154.5 (148.8); tail, 212-255 (231.4); culmen, 27-30 (28.2) 

 mm. Five males and one female from eastern Siam: Wing, 144- 

 157.5 (148.5); tail, 220-235 (228); culmen, 27-30 (28.5) mm. 



The present form ranges over nearly the whole of Burma south of 

 the Chin and Kachin Hills down to northern Tenasserim, the Shan 

 States, w^estern and northern Siam, and Yunnan.

DENDROCITTA VAGABUNDA SAKERATENSIS Gyldenstolpe 



DendrociUa rufa sakeratensis Gyldenstolpe, Bull. Brit. Orn. Club, vol. 41, p. 32, 

 1920 (Sakerat, eastern Siam). 



Two males and one unsexed, Pak Chong, February 7, 1925, De- 

 cember 21, 22, 1926; one female. Pang Sok, August 23, 1920; one 

 male and one female, Nong Mong, Muang Krabin, August 22, 24, 

 1925; one male, Udon, February 10, 1929; four immature males of 

 various ages, Chantuk, June 14, 16, 1934. Dr. Smith gives the soft 

 parts as: Iris dull reddish brown; bill and legs black. 



This series averages darker above and below than the series from 

 northern and western Siam previously commented upon, but t.-cre 

 seems to be little or no difference in size. 



The immatures taken at Chantuk range from about adult size to 

 about half grown. The young resemble the adult but are browner 

 on the head, lighter on the breast, and the outer feathers of the tail 

 are tipped with cinnamon-buff. This latter character seems to per-
