western Siam and probably reaches southwestern Siam, but I have 

 seen no records from this part of the country. 



There is a specimen in the British Museum from Meklong, central 

 Siam.^* De Schauensee ^^ says that it is a common bird in dry lowland 

 forest, ascending the hills to about 1,500 feet. 



CIRROPICUS CHLOROLOPHUS CHLOROLOPHOIDES (Gyldenstolpe) 



Brachylophus chlorophoides Gyldenstolpe, Orn. Monatsb., 1916, p. 29 (Koon 

 Tan, northern Siam). 



One male, Doi Hua Mot, August 24, 1934; four males and three 

 females, Khun Tan Mountains, 3,000-4,300 feet, November 21, 1928, 

 May 11-17, 1933; five males and four females, Khun Tan, 4,000 feet, 

 October 17-22, 1929, August 23-September 6, 1930, March 1, 4, 1932; 

 one female, Doi Nangka, November 22, 1930; one female. Pang Meton 

 (Doi Nangka), May 2, 1931 ; one male. Khan River, February 8, 1932; 

 one male, Huey Salob, January 3, 1933; one female. Ban Nam Kien, 

 Nan, April 21, 1930; one female, Wang Kien, Kanburi, March 12,

I have had only one male of Cirropicus chlorolophus chlorolophus for 

 comparison. It is more of a yellowish green above; the nuchal crest is 

 a deeper yellow; the chest is more of a deep olive, less greenish; the 

 red on outer web at the base of the inner primaries is less pronounced; 

 the red on the forehead and superciliary is less extensive, and there 

 are some other differences. 



C. c. chlorolophoides ranges from the southern Chma and Kachin 

 Hills, Burma, south to the southern Shan States and Tenasserim and 

 eastward to northern Siam and northwestern Laos. In Siam it is 

 apparently common all over the northern part of the country. Dr. 

 Smith's specimen from Wankien is from about as far to the southwest 

 as the form is known to range. 



C c. chlorolophus (Vieillot) occurs from Sikldm, Bhutan, Assam, and 

 the hill tracts of eastern Bengal to the northern Shan States and 

 Yunnan. Other forms occur in India. The southern forms are listed 

 under conjundus.
