THE BIRDS OF SOUTHWEST AND PENINSULAR SIAM. 223 



and in Bandon in June and July. How far north it extends is not 

 at present known. Gyldenstolpe's specimen from Koh Lak is the 

 most northerly record ; Trang is probably near its southerly limit as 

 it almost certainly does not occur in Perils.

" Iris dark or dark hazel ; bill black ; feet lavender ". 



Total length 6, 212; 2, 212; wing 6, 102; 9. 104; tail S,

We have not been able to compare these with topotypical 

 Sumatran specimens : they differ, however, in no way from specimens 

 from the South Malay Peninsula. Older males become more uniform 

 on the sides of the chest and tend to lose the orange barrings. 



These are the most northerly specimens on record ; the species 

 has not yet been recorded from the Indian Empire but is certain to 

 be found in Southern Tenasserim, the present locality being very few 

 miles from the border. The bird is most strictly associated with 

 limestone hills such as are found throughout the Malay Peninsula 

 on both sides of the main range, and we know of no specimens which 

 have been obtained more than a very few miles from such hills. The 

 association is correlated with the presence of certain species of shells 

 on the limestone, which constitute the principal article of food of 

 these birds.
