BIRDS FROM SIAM AND THE MALAY PENINSULA 269' 



male and one female, Nong Mong, Krabin, August 20, 1925; one 

 female, Nong Khor, Sriracha, November 10, 1920; two m.ales, Sakeo, 

 near Krabin, May 3, 192S; one immature male, Kao Lem, December 

 25, 1930. 



Dr. W. L. Abbott collected three males, Trang (Prahmon, April 

 5, 1896; Chong, January 21, 1897; Trang, March 2, 1809); one male, 

 Victoria Point, Tenasserim, March 31, 1900; one male, Tanjong 

 Laboha, Trengganu, September 30, 1900. 



Of the 14 adult males in the above series from Peninsular and: 

 southeastern Siam, nine have no red on the outer web of the three 

 outer primaries, while six have a red spot on the outer web of the 

 third outer primary. All have the outer web of the central tail 

 feathers red. Four males from southern and southeastern Siam have 

 only the two outer primaries with no red on the outer web; the outer 

 web of the two central tail feathers is entirely red in all. They are 

 more or less intermediate between northern Siamese and Peninsular 

 Siamese specimens but are nearer the latter, and I am inclined to 

 place them there as Robinson has done.®* 



Eleven males from Penmsular and southwestern Siam measure: 

 Wing, 87.5-93 (89.8); tail, 73.5-81 (77.5); culmen, 13-15 (14) mm. 

 Four males from southeastern Siam: Wing, 92.5-93 (92.7); tail, 

 75-80 (75); culmen, 13-14.5 (13.7) mm. 



The United States National Museum possesses only one male of 

 P. J. xanthogaster from Sumatra. It is smaller than flammijer, and 

 four of the outer primaries are without red on the outer web. It 

 measures! Wing, 77.5; tail, 65; culmen, 12 mm. 



P./. xanthogaster not only occurs in Sumatra and Borneo but also 

 in the southern Malay States as far north as the northern boundary 

 of Negri Sembilan and Johore. It apparently does not extend north 

 to the Siamese territory. P. j. flammijer ranges from the northern 

 boundary of Selangor and Pahang north through Peninsular Siam to 

 Tenasserim and southwestern Siam and extends eastward through 

 southern Siam to southeastern Siam and probably into Cambodia.

Two males, Khun Tan, 4,000 feet, February 13, 1932. 



These two males agree fairly well with three males from western 

 Yunnan, except the wings are slightly smaller. The wings of the two. 

 Siam males measure 86.5 and 90 mm. Three males from Yunnan: 

 93, 93.5, and 94.
