THE BIRDS OF SOUTH-WEST AND PENINSULAR SIAM. 205 



have been named Corydon sumafranus hrunnescens (Hartert, Bull. 

 Brit. Orn. Club, xxxvii, 1916, p. 4), Fairly common in Peninsular 

 Siara, extending northwards to Chiengmai and the Karen Hills. 



Fresh skins have the concealed back spot almost invariably 

 fierj'' orange or scarlet, which in many eases fades to apricot or 

 pinkish yellow.

This bird was found to be very abundant in drj'- bamboo 

 jungle at Tapli, flying in flocks of five or six individuals and, as 

 Davison notes, not at all eas}^^ to alarm. At Tasan in deeper, more 

 evergreen, jungle ifc was much rarer, and at other places we did not 

 come across it at all. 



Davison did not collect it on the Pakchan, nor did Oates's 

 collectors, so that the present series is a considerable extension of 

 range for the form.
