Examination of these and many others from various parts of 

 the Malay Peninsula, Sumatra and Borneo shows that all but the 

 adult males have some small trace of scarlet on the feathers of the 

 forehead, which appears to be lost by a direct change to mauve or 

 lilac, as many feathers are mauve at the tips with scarlet near the 

 shaft. 



Mr. Gairdner's record seems the most northerly for Siam ; 

 but on the Burmese frontier it has been obtained at Myawadee, 65 

 miles N. by E. of Moulmein. In the southern parts of Peninsular 

 Siam it is a very common forest bird.
