The male from Doi Hua Mot is molting the tail, and it is too early to 

 make out the pattern. 



This race occurs in southeastern Yunnan, northwestern Tonkin, 

 northern Laos, and northern Siam. De Schauensee *" secured six 

 specimens at Chiengdao, 4,500-5,500 feet, wliich he identifies as P. 

 m. commixus, a form confined to southeastern China and having the 

 back entirely gray. Deignan *^ gives the additional localities of Doi 

 8utep and Doi Angka.

Parus subviridis Blyth, Tickell MS., Journ. Asiat. Soc. Bengal, vol. 24, p. 2G5, 

 1855 (Tenasserim). 



Five males and two females, Doi Nangka, November 10-19, 1930, 

 April 22-May 6, 1931; one female. Pang Meton (Doi Nangka), April 

 30, 1931; one male and one female, Doi Hua Mot, August 26, Sep- 

 tember 4, 1934. 



A male and female in the United States National Museum are from 

 the Langbian Peaks, South Annam. The male, when compared with 

 the Siamese series, has the back grayer, less suffused with yellow, 

 on the sides of the breast, the yellow is less bright, and the wliite on 

 the secondaries and tail is more restricted; the female does not differ 

 materially, however. The Langbian Peaks are quite isolated from the 

 rest of the known range of the form. 



The wings of five Siamese males measure 76-79 (77.2) mm; the 

 wing of the Langbian Peak male, 76 mm. 



The known range of M. s. subviridis is Tenasserim, Burma, northern 

 Siam, to Laos and (?) southern Annam. 



^'VTien Count Gyldenstolpe published his list of the birds of Siam, 

 only one specimen of this bird had been taken in the country, at Doi 

 Ngachang south of Lakorn Lampang,^^ since then it has been found 

 not uncommon by several collectors *^ on Doi Sutcp from 3,500 feet 

 to the summit, and it will probably be found on other mountains of 

 sufficient elevation.
