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 
bushes and undergrowth, ‘Their food consists of insects of all 
kinds, but largely small beetles, seeds and some soft fruits such as 
the various Fc, In the stomachs of some specimens killed in 
N. 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 the nuchal hairs short. The wing is comparatively 
short and rounded and the tail-feathers well graduated. 
The peculiar structure of the feathers of the crown and its large 
size will suffice to separate this Bulbul from all others.
