Genus TRACHYCOMUS, Cabanis, 1851. 



This genus is represented by a single bird 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 strong and the 

 nuchal hairs short. The wing is blunt, and the tail is well 

 rounded. 



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

 size will suffice to separate this Bulbul from all others.
