The powerful construction of the bill of this group separates 
it at once from the other species of the Muscicapide, with 
which in the depression and breadth at the base of that mem- 
ber, the strength of the rictal bristles, and the general charac- 
ters of the wings and legs, it otherwise accords. This strength 
of bill would incline us to place the bird among the Laniade, 
and in the subfamily of Tyrannina, Swains., of which it might 
thus be considered to form the Australian representative, did 
not the other characters of its structure evince a more predomi- 
nant inclination to the Muscicapidæ than to the Tyranni. The 
eroup may, however, be considered to stand intermediately 
between the two families; and might perhaps be referred with 
equal propriety to either, according to the characters which 
each naturalist would select as most predominant, and most 
convenient to guide him in his subdivisions. The habits of the 
birds of the group, hitherto unknown, will have much influence 
in determining its exact station. ci
