what we have advanced respecting Megalophus, for 
the crests, so common among the Drongo shrikes 
( Dicrurus J, are certainly more like that of Mega- 
lophus , in point of structure, than are those of the 
Tyrannince ; all the latter being concealed, and 
the feathers not lengthened. 
W e have already seen how completely the orioles 
are represented by Monacha ; and we shall now 
find that both these are only prototypes of the 
Cdjlepyrince. The colouring of Monacha carinata 
is that of a Ceblepyris ; while the C. lobata has 
exactly the same sort of naked wattles so conspi- 
cuous in Monacha telascopthalmus. Lastly, the 
Tyrannulce represent Rkipidura in being the only 
shrikes which have the perfectly depressed bill of 
the flycatchers, and in the typical species having 
broad rounded tails. This analogy, however, is as 
weak as the last and the two first are the reverse ; 
so that we have another proof, that in these sort of 
comparisons some resemblances will be much more 
strong, or rather better known, than others. Our 
inability, however, to discover other analogies than 
those we have just mentioned, between ffliipidura 
and Tyrannulce, is of little consequence to our 
present purpose; for as we think it indisputable, 
after what has been said, that Rhipidura is a 
rasorial type, our only desire is to throw some 
additional light upon the analogies of Megalophus. 
This will be effected by looking to three of the 
genera composing the circle of the Thamnophilince, 
or Bush-shrikes, and comparing them with the
