season, whilst in the breeding season it keeps to heights between 

 4,000 and 7,000 feet. They collect in flocks of a dozen or more 

 individuals in winter, feeding both on the higher trees and in the 

 buslies and undergrowth. Their food consists of insects of all 

 kinds, but largely small beetles, seeds and some soft fruits such as 

 ihe various Fici. In the stomachs of some specimens killed in 

 jS". Cachar were numerous tiny fragments of quartz. In the 

 breeding season they seem to desert the higher trees and to keep 

 to the lower jungle. Their notes are those of the family but full, 

 soft and sweet and easily distinguishable from those of their 

 nearest relations. They fly well but are not very active or quick 

 on their feet. 



Genus TRACHYCOMUS Cabanis, 1851. 



This genus is represented by a single species of large size, 

 striated plumage and peculiar structure. It has no crest but the 

 crown is covered with dense, bristly, decomposed feathers of a 

 yellow colour. The tarsus is remarkably strong, with a few 

 scutellations in front and sometimes quite smooth. The bill is 

 short, being about half the length of the head, the rictal bristles 

 are strong and tlie nuchal hairs short. The wing is comparatively 

 ^hort and rounded and the tail-feathers well graduated. 



The peculiar structure of the feathers of the crown and its large 

 size will suflice to separate this Bulbul from all others.
