Small birds with short stout bills, short rounded wings, long wedge tail of 
ten feathers and stout legs and feet. 
The bill is a little more than half the length of the head, stout; culmen 
arched, tip little decurved, laterally compressed, nasal groove short, the nostrils 
linear, but rather diagonal and operculum projecting ; frontal feathers en- 
croaching on nasal groove as far as, but not obscuring, the nostrils ; rictal 
bristles strong and prominent, but no nasal bristles; lower mandible fairly 
stout, interramal space short and sparsely feathered. 
The wing is rounded, the first primary about half the length of the third, 
the second intermediate, but only about equal to the tenth and secondaries, 
the third to eighth being subequal and longest.
