This considerable series is fairly uniform. The sexes are alike in 

 color and size. 



Six males measure: Wing, 99-102 (100.3); tail, 59-62 (60.2); 

 culmen, 22-26 (23.7) mm. Nine females: Wing, 97-105.5 (99.5); 

 tail, 55-63 (58.9); culmen, 23.5-27 (25) mm. 



The form ranges from the southern Shan States and Burma to 

 Muleyit, Tenasserim, and northern and western Siam. 



Gyldenstolpe *^ first reported this form from northern Siam from 

 Doi Par Sakeng; Gairdner ^^ took it in the Raheng District, western 

 Siam, and it has been taken on Doi Sutep by a number of collectors 

 beside Dr. Smith. 



It is evidently a common mountain bird in northern Siam. De 

 Schaunensee ^^ states that on Doi Sutep it occasionally is found as low 

 as 2,500 feet but abundant above 4,500 feet. 



CYANOPS FRANKUNI TRANGENSIS Riley 



Cyanops franklini trangensis Riley, Proc. Biol. Soc. Washington, vol. 47, p. 116, 

 1934 (Kao Nom Plu, 3,000 feet, Trang, Peninsular Siam). 



Dr. W. L. Abbott collected two males and three females in the 

 mountains of Trang (Kao Nom Plu, 3,000 feet, February 22-24, 

 1897; Kao Soi Dao, 2,500 feet, February 12, 1899). He describes 

 the soft parts as: Iris dark brown or dark red; bill black, leaden at 

 base beneath; feet greenish leaden or pale green. 



This form is similar to rarnsayi of northern Siam but has a larger 

 heavier bill; the crown spot and throat are a more golden yellow; 

 the supra-auriculars, auriculars, sides of neck, and jugulum darker 

 and duskier; above and below a darker green. 



The two males and three females measure: Wing, 98-101 (99); 

 tail, 55-61 (59); culmen, 26-28 (27) mm. 



The form so far as loiown is confined to the mountains of Trang. 

 It may extend to the mountains of Nakon Sritamarat and Bandon.
