what we have advanced respecting Megalophus, for 

 the crests, so common among the Drongo shrikes 

 (Dicrurus), 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. 



We have already seen how completely the orioles 

 are represented hy Monacha; and we shall now 

 find that both these are only prototypes of the 

 C&lepyrince. 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 Rhipidura 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 Rhipidura 

 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
