BIRDS FKv^M SIAM AND THE MALAY PENINSULA 69 



much too red and does not show the contrast between the wing coverts 

 and the flight feathers. There may, however, be considerable varia- 

 tion in the females. 



The male taken on Kao Kuap was recorded by me.^^ The two 

 from Kao Sabap add an additional locality in Siam, though not far off. 

 The white concentric lines to the feathers above in the Kao Kuap male 

 are somewhat coarser than in the male from Kao Sabap. 



The range of G. lewisi extends from the mountains of southern 

 Cambodia to southeastern Siam. 



GENNAEUS NYCTHEMERUS RIPPONI Sharpe 



Gennaeus ripponi Sharpe, Bull. Brit. Orn. Club, vol. 13, p. 29, 1902 (Southern 

 Shan Hills, Burma). 



One male and one female, Doi Nangka, April 26, 1931 ; two females, 

 Khun Tan Mountains, 3,000 feet, May 15, 1931. 



The above male agrees with a male from east of Phong Saly, Laos, 

 that I had previously identified as andersoni, but Stuart Baker ^^ 

 claims the latter is a hybrid Gennaeus lineatus sharpii. The Laos 

 male does not exactly agree with the plate of the type of Euplocamus 

 andersoni Elliot ''* in detail, but it is close. 



The two females from the Khun Tan Mountains are somewhat 

 different from the Doi Nangka female. The black on the crest tip in 

 the latter comes much farther forward (about even with the eyes) and 

 the upperparts are considerably lighter. Whether these differences 

 are due to individual variation I cannot determine with the material 

 on hand. All the females have bare incubation patches. 



Gyldenstolpe " saw one on Doi Par Sakerg that he provisionally 

 assigned to this form, but took no specimens; Stuart Baker ^* assigned 

 specimens in the Herbert collection from Muek Lek and Pak Chong, 

 eastern Siam to this form; Deignan " found a silver pheasant common 

 on Doi Sutep from 4,500 feet to the summit; Aagard ^* afterwards took 

 a pair on this mountain at 4,600 feet; and de Schauensee ^^ recently 

 took a small series at Chiengdao and Chiengmai. 



This form extends from the southern Shan States, Burma, to 

 Yunnan, northern and eastern Siam, northern Laos, and northern 

 Annam.
