The birds of the group just described which are in our collec- 
tion are in general in bad condition, and we have been obliged 
to confine ourselves to a few details only of their characters. 
Even still we are not satisfied with our distinguishing marks.

This genus bears a very close resemblance to the group of 
Timalia of the Javanese ornithology. In the shortness and 
roundness of the wings, in the length and graduation of the tail, 
in the carinated bill, and in the loose and decomposed feathers 
of the body, it comes so close to that group that we should at 
once refer our species to it, were it not for the singular bristles 
that spring from the front of the forehead above the bill, and form
