GAMPSOKHYNCHUS RUFULUS TORQUATUS Hume 



Gampsorhynchus torquatus Hume, Proc. Asiat. Soc. Bengal, 1874, p. 107; Stray 

 Feathers, vol. 2, p. 446, 1874 (Younzaleen, Salween District, Tenasserim). 



Six males, Khun Tan, 4,000 feet, October 19, 1929, August 28, 1930, 

 and February 15-17, 1932; one female, Doi Nangka, November 18, 

 1932; one male, Khun Tan Mountains, 3,000 feet, May 13, 1933; one 

 male, Kao Pae Pan Nam, Lamsak, February 19, 1934. 



In tliis series the dark jugular band is interrupted in one female from 

 Doi Nangka, one male from Khun Tan, and one male from the Kao Pae 

 Pan Nam. In a male received from the Raffles Museum from the 

 Raheng district there is no dark jugular band at all. The remaining 

 males have the jugular band complete. The color of the back extends 

 forward onto the nape but is darker and usually mixed with white 

 there, though in a few specimens not; the rest of the head is white. 



De Schauensee ^ states that birds from Chiengmai are intermediate 

 between torquatus and luciae of Tonkin; his collectors found an adult 

 male and an adult female accompanied by fully fledged young at the 

 same place in mid-July. 



Deignan ^ says it is once recorded from Doi Sutep, 3,800 feet; not 

 uncommon on some hills near Chiengmai. Chasen and Kloss ^ have 

 recorded it from the Raheng district, western Siam. 



The form evidently occurs from the Toungoo Hills and Karenni, 

 Burma, to northern and western Siam and south to Tenasserim; it 

 also occurs in Lower Laos, southern Annam, and Cochinchina. In the 

 mountains at the southern end of the Malay Peninsula a larger and 

 darker form or species, G. saturatior Sharpe, occurs. It may extend 

 into the mountains on the southwestern border of Patani. 



CHRYSOMMA SINENSIS SINENSIS (Gmelin) 



Parus sinensis Gmelin, Systema naturae, vol. 1, pt. 2, p. 1012, 1789 (China, error). 



One male. Bung Borapet, central Siam, June 28, 1932. 



Deignan ^ says this form occurs uncommonly on the plain at 

 Chiengmai. To the eastward in Yunnan, C. s. major occurs. It is a 

 larger, darker-colored form with a longer tail. 



De Schauensee '° identifies a single male from Chiengmai as C. s. 

 major. The specimen from Bung Borapet has been compared with a 

 specimen of Chrysomma sinensis major from Mengtsz, Yunnan, the 

 type locality of the form, and the latter is considerably larger, with 

 a much long-er tail and darker breast.
