SIPHIA STROPHIATA STROPHIATA Hodgson 



Siphia strophiata Hodgson, Indian Rev,, vol. 1, p. 651, 1837 (Nepal). 



One male, Khun Tan Mountains, November 22, 1928; one male, 

 Doi Angka, 5,000-6,000 feet, December 7, 1928. 



De Schauensee *^ found it quite common in December on Doi 

 Sutep, 4,500 feet, and Deignan *^ reports it from the same mountain 

 at 4,500 to 5,500 feet in winter. De Schauensee ** on his third expe- 

 dition took specimens at Chiengdao in January and Cliiengmai in 

 February. 



The form breeds in the Himalayas and the high mountains of 

 western China and winters in Tenasserim, northern Siam, Laos, 

 Tonkin, and northern Annam. 



In south Annam, at the Langbian Peaks, a more reddish-backed, 

 grayer-throated form, S. s. fuscogularis, is found, which has been 

 recorded from the northern Shan States; if this record is reliable, it 

 possibly may occur on the high mountains of Siam as a breeding bird.

One male, Kao Soi Dao, Trang, December 30, 1933. 



Dr. W. L, Abbott took an adult male at Kao Soi Dao, 1,000 feet, 

 Trang, February 15, 1899. 



These two specimens seem to be the only records for Siam. Farther 

 south in the Malay States it is widely distributed but nowhere com- 

 mon. The males from Trang agree with a male from the Semangko 

 Pass, Selangor-Pahang boundary. 



This form ranges from the mountains of Sumatra to the Malay 

 States and Peninsular Siam. 



Farther north in Tenasserim C. c. cyanea occurs. It is a darker 

 blue with the white on the breast more restricted. 



C. c. concreta is a dark-blue bird with a white breast, the second, 

 third, and fourth tail feathers largely white on the inner web. The 

 female is brown, with a white crescent on the chest. Wing in male, 

 about 88 mm.
