204 MESSRS. ROBINSON AND KLOSS ON 



The Sumatran bird, with wliich tl\e majority of Mahiyan 

 specimeua agree, lias been separated from tlie typical Javan V)ird, 

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

 present form. It is not impossible, 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 1 fills and North Siam, the three 

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

 2000 ft., Nakon Sri Tamarat, 14th March 1922, are the only ones 

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

 fairly common. The two males now before us differ from a long 

 series of Malayan and Sumatran l)ird8 in being paler both above and 

 below.
