MESIA ARGENTAURIS TAHANENSIS Ven 



Mesia argcntauris tahanensis Yen, Science Journ. (Sun Yat-Sen Univ.), vol. 6, 

 no. 2, p. 63, 1934 (Mount Tahan, Pahang). 



Two males, Kao Luang, 3,000 feet, Nakon Sritamarat, July 14, 

 1928. 



These two specimens when compared with four males from north- 

 ern Siam are more of a buffy citrine on the back, and tlie collar on 

 the hindneck is a deeper yellow; below there is little or no difference. 

 A male and a female from the Semangko Pass, Selangor-Pahang 

 boundary, when compared sex for sex with northern specimens have 

 the hindneck collar a much deeper yellow also. The two jnales from 

 Kao Luang are not so deep a yellow in the hindneck collar or on the 

 throat and chest as the Semangko male. 



The United States National Museum possesses a male from Sikkim 

 that in the color of the hindneck collar and the throat approaches the 

 Semangko male; the back lacks the buffy citrine of the more southern 

 bird, however, and in this respect approaches the northern Siamese 

 series but is even grayer. In measurements the Kao Luang m.ales 

 agree with northern specimens. As a matter of fact they are some- 

 what intermediate, but probably they had better be placed with the 

 southern form for the present. 



Seven specimens from northern Siam (four males and three females) 

 measure: Wing, 76-80 (77.9); tail, 69-73 (70.6); culmen, 14-15.5 

 (14.7) mm. Two males from Kao Luang: Wing, 81, 81 ; tail, 74, 74; 

 culmen, 15, 15.5 mm. One male (first) and one female from Semangko: 

 Wing, 74, 71; tail, 69, 71; culmen, 14, 14 mm. 



M. a. tahanensis was reported from Kao Nawng, Bandon, above 

 3,000 feet, by Robinson ^° and from Kao Luang, between 3,000-5,800 

 feet, Nakon Sritamarat, by Robinson and Kloss.^' In the high 

 mountains of the Malay States apparently it is more abundant and 

 more widely distributed. 



The form ranges from the mountains of the Malay States north- 

 ward to the mountains of Bandon, Peninsular Siam. 



A form occurs in the mountains of Tonkin, one in southern Annam, 

 one in Sumatra, and two in Burma.
