Walden, writing of males from Moulmein, says (P. Z. S. 

 1866, p. 544), " when compared with a Sumatran skin they 

 appear less brightly and richly coloured. In the latter bird 

 the rufous of the breast and throat is deeper in tone and 

 descends lower down ; it is separated from the yellow of the 

 abdominal region by a more trenchant line. In the Tenas- 

 serim species the rufous dies away into the yellow ; in them 

 also the bill is decidedly longer, while in all other dimensions 

 they are inferior to the Sumatran bird.'^ Perhaps, therefore, 

 Tenasserim birds represent a third race yet unnamed. 



Oates states that the nestling resembles the female (Faun. 

 Brit. Ind., Birds, ii. p. 372) : but my young female differs in 

 having the throat and foie-breast pure yellow, not rufous ; 

 and in having, the frontal feathers and a fairly distinct 

 supercilium extending behind the eye pale yellow also ; the 

 iris is brown.
