Type. 



Cranium very broad in proportion to its length, much more so than among the 

 Muscicapidce, which in many respects it resembles ; interarticular bones of moderate 

 length. Palatine bones consisting of a narrow strip on their outer edges ; at about 

 half their length there is a strong, flattened, and blunt styliform process, pointing 

 inwards and backwards, from about two-thirds of their length the points are bent 

 suddenly inwards towards the interarticular bones, and are expanded at their junction 

 with them. 



Sternum and Pelvis similar to the Muscicapidce . 



Coracoids shorter than in Muscicapa. 



Furculum at the junction of the rami with a long, somewhat triangular, process, 

 pointing backward. 



Wing-hones short ; ulna longer than the humerus.
