308 MESSRS. ROBINSON AND KLOSS ON 



No specimens of this thrush have actually been taken in Siani. 

 It is, liowever, certain to occur on the higher mountains as we have 

 a fair series from tlie mountains of the Malay States and Sumatra. 



437. Oreocincla aurea horsfieldi Bp. 



Oreocincla horsfieldi, Bonaparte, Rev. et Mag. Zool., May 1857, p. 



•205 (Java). 

 Oreocincla horsfieldi afitinis, Richmond, Proc. Biol. tSoc. Wash, xv, 



1902, p. 158 (Khao Nok Ram, Trang, 3,000 ft.). 



For the present we cannot admit the validity of 0. h. afiUnis, 

 founded on a single specimen and depending on a slight difference in 

 the wing formula : we have specimens from Khao Ram and Khao 

 Luang, 1000-2000 ft., in Nakon Sritamarat, which are not separable 

 from Javanese birds, and Sumatran birds are undoubtedly identical 

 also. 



Oreocincla dauma (Lath.). 



Tardus dainna, Lath., Ind., Orn. I, 1790, p. 362 (India; Kashmir). 

 Oreocincla dauma, A., p. 256 (Muleyit fountain). 

 Geocichla dauma, C. I., p. 7. (Muleyit mountain). 



It is almost certain that this bird will be found^in migration 



^n Peninsular Siam during the winter months, insomuch as Mr. E. 



Seimund obtained an adult female on 29th November, 1918, on Pulo 



Rumpia, the largest of the Sembilan Islands, off the mouth of the 



Perak Ri\er, Malay States.
