The elusive cuckoo shrike seems to be closely related to E. everetti, but 

 no direct comparison can be made as the latter species is not represented 

 in the Bureau of Science collection.

Bill short and slightly flattened; wing and tail nearly equal in length, 

 or wing shorter than tail; rectrices very narrow and strongly graduated,
