204 MESSRS. ROBINSON AND KLOSS ON 



The Sumatran l)ii'd, with wliicli the m.-ijoiity of Malayan 

 specimena agree, has been separated from the typical Javan bird, 

 which has yellow under tail-coverts, these being vinaceous in the 

 present form. It is not impossil)le, however, that the bird from the 

 Lam pongs District, South Sumatra, adjacent to the Sunda Straits, 

 belongs to the Javan form. 



Though found in the Karen liills and North Siam, the three 

 specimens from Bandon recorded above, and a. pair from Khao Luang, 

 2000 ft., Nakou Sri Tamarat, 14th March 1922, are tlie only ones 

 hitherto obtained from Peninsular Siam, where, however, it must be 

 fairl}' common. The two males now before us differ from a long 

 series of Malayan and Sumatran bii-ds in being paler both above and 

 below.
