specimen the frontal feathers are buffy-whitej becoming 

 white over the eye ; in the smaller^ the forehead is huffy- 

 white for ahnost 7 mm., some of its posterior feathers being 

 partly coloured like the crown ; it has also the sides of the 

 body considerably more fulvous than the other. 



Of specimens lent to me by the Indian Museum, examples 

 from Darjeeling (2), Bhamo, and Thayetmyo have white- 

 tipped tails and white centres to the black ear-coverts, 

 which are continuous with the pectoral band ; but a 

 skin from the lower Irrawaddy has buff tips to the tail- 

 feathers and the ear-coverts white, dusky feathers occur- 

 ring only between them and the white eyebrow^ as in 

 Siamese birds.

The Koh Lak birds are much smaller than the other sub- 

 adult specimen (wings 122, 120 mm.), but these three only 

 differ from old birds in the reduced amount of ashy on the 

 hind neck. In the young individual, however, the wings are 

 suffused with the colour of the mantle and the middle of 

 the body below is much washed with brown. 



I found these birds going about in parties, moving quickly 

 through the undergrowth. One of a flock that was brought 

 down wounded was badly mobbed by its companions as it 

 lay on the ground.
