 Brachi/j}ter>/.r tnrayi, H., p. 106 (Khao Nawng, Bandon). 



Only found as. yet on Khao Nawng and Khao Luang, Nakon 

 Sritamarat, P. Siam, at between 8,000 and 4,000 feet. 



After examination of topotypes from Java and a large series 

 from Sumatra we. are forced to the conclusion that the Siamese birds 

 are identical with the Javanese, and differ from those of Sikhim and 

 the mountains of the Federated Malay States (H. I. nipalensis and 

 H. I. wrayl) in that the males are never slaty. Davison (Stra}'' 

 Feathers, vi, 1878, p 236 : Muleyit) and Gates have already com- 

 mented on this curious fact (Fauna Brit. Ind. Birds, i, p. 189). 

 430. Siva cyanuroptera sordidior Sharpe. 



Sirci sordidior, Sharpe, P. Z. S. 1888, p. 276 (Batang Pad mg Mts., 

 Pevak) ; H., p. 106 (Bandon). 



The exact identification of this form as occurring in Penin- 

 sular Siam is a matter of some doubt, as the five specimens from 

 Khao Nawng, Bandon, and others recently obtained on Khao Luang, 

 5,500 feet, Nakorn Sritamarat, on which the occurrence rest.9, are 

 all in very worn and faded plumage. The subspecies is, in any event, 

 not N'cry strongly differentiated from 8. c. sordida Hume, from 

 Muleyit in Tenasserim.
