BIRDS FROINI SIAJM AND THE MALAY PENINSULA 117 



specific rank. The males of the two forms are quite distinct, the head 

 and hindneck in tusalia being darker and the iridescence purple 

 instead of green. The chestnut bars above are narrower and darker. 

 The ranges are widely separated by territory where no forms of the 

 species occur. 



Gyldenstolpe ^^ reports it extremely rare in Siam and at that time 

 this form had been taken only at Khun Tan; Deignan ^"^ records it as 

 uncommon on Doi Sutep at 3,500 to 5,500 feet. Chasen and ICioss ^* 

 record a single male from Hue Pandeng, Raheng, and say it is rather 

 small for typical tusalia.] wing of their male is given as 186 mm. This 

 latter specimen is now in the United States National Museum and, 

 according to my measurement, the vnng is 190 mm. It agrees with 

 Dr. Smith's males from farther north. The wing of the Doi Angka 

 male measures 190 mm. That of the Doi Nangka male measures 

 188 mm. There are no topotypical specimens of the form available 

 for comparison. De Schauensee ^® took a male and female at 

 Chiengdao. 



This is a mountain form and extends from the Himalayas through 

 northern Siam to Laos, Tonkin, and Annam. So far there appears ta 

 be no authentic record from the Malay Peninsula.

One male and one female, Khun Tan, 4,000 feet, February 29,

Williamson *° records it from Raheng, 1,500 feet (May), and 

 from Muang Wang; Chasen and Kloss *^ record a series taken by 

 Gairdner in the Raheng District, three of which were afterward 

 sent to the United States National Museum ; Deignan *^ took it in 

 March on Doi Sutep, 5,500 feet; and de Schauensee ^ later secured a 

 male there at 3,500 feet. 



The form ranges from Pegu to Mulej^it, the South Shan States,,
