Very small “ Muscicapine ” birds with very broad flat bills, medium wings, long 
wedge tail and small legs and feet. Coloration peculiar. The bill is very broad 
and flat with a prominent keel ending in a strongly hooked tip. The sides of 
the culmen very flattened, the nostrils reduced to linear slits in front of the 
feathering, though a couple of nasal bristles are there seen erect. The under 
mandible is also very flat and four strong rictal bristles are present. The wing 
is rounded and shorter than the tail. The third, fourth, fifth and sixth 
primaries are longest and equal, the seventh equal to the second and the first 
more than half the length of the latter. 
The tail is long and wedge-shaped, the middle six feathers about equal in 
length, the outside ones about half their length. The legs and feet are small 
and weak. N 
The coloration is very different from any other species placed near, viz., 
black, green and yellow, which suggests that these aberrant little birds are not 
correctly located here.
