Consistently common in every suitable locality visited in 

 Peninsular Slam, affecting chiefly bamboo jungle near w^ater; not as 

 a rule found near the sea or in the mangrove zone. • 



The races of this BroadbiJl have 'recently been discussed ad 

 iiausedm, but after all little has been elicited that has not appeared 

 in Hume and Davison's classic paper. Broadly speaking it may be 

 stated that there is a progressive increase in the amount of white on 

 the tail as we proceed northwards. Bornean birds .have least, and 

 to this locality the name Cymborhynchus macrorhyncJnts macror- 

 hynchus is attached, though it is by no means certain that it 

 properly applies : West Sumatran birds are next ; and if distinct, 

 will have to be called C. m. leinniscatibs Raffles, while the continental 

 birds south of Aracan are C. m. malaccensis. The present series 

 have white on the four outer pairs of tail feathers; one male from 

 Tasan has it on five, one female from Tasan on three pairs only.
