edl}^ T. affinis and its forms go through the same process. Dr. 

 Salomonsen,^^ in his remarks in the original description, says that only 

 the red phase seems to be found in indochinensis. I believe that the 

 red and the white plumages in this species are age characters, not 

 phases in the sense accepted in ornithology. Undoubtedly the males 

 breed in both plumages. 



The form is lighter above and below than T. a. affinis. 



Eight males from Laos (1), eastern (1), and southeastern Siam (6) 

 measure: Wing, 90-97 (92.5); middle tail feathers, 228-330 (269.4); 

 outer tail feather, 77.5-95 (82.9); culmen, 18.5-21 (20) mm. Ten 

 males from Peninsular Siam (Trang north to Bandon): Wing, 91-98 

 (95.4); middle tail feathers, 241-343 (284); outer tail feather, 77-89 

 (80.7); culmen, 19-21.5 (20.3) mm. Four males from Patani: Wing, 

 92-99 (95); middle tail feathers, 255-330 (285.7); outer tail feather, 

 78-81 (79.2); culmen, 20-21.5 (20.9) mm. 



Its range is from northern Siam, Laos, northwestern Tonkin, 

 Annam, Cochinchina, and Cambodia to southern Siam and down 

 Peninsular Siam to Patani. 



Two of the males from Patani are in the white plumage and two in 

 the red plumage. The two latter are as pale below and above as 

 specimens in this plumage from southeastern Siam ; in fact, they show 

 no indication of grading toward T. a. affinis. 



Dr. Smith took no specimens of indochinensis in northern Siam. 

 Gyldenstolpe ^^ reports it fairly rare at Khun Tan ; Deignan ^ observed 

 it several times on Doi Sutep in July and August. In southern and 

 Peninsular Siam it is evidently much more abundant. It is supposed 

 to be resident throughout the year.
