212 MYIAGRA. 



It would be vain, in the present state of ornitho- 

 logy, to think of explaining the whole of these ana- 

 logies ; yet if a few are established, they will tend 

 much to illustrate our preceding analogies. Rhipi- 

 dura and Cryptolopha, as we have already seen, 

 are representations of each other ; and if My'iagra 

 longicauda really belongs to that group, it becomes 

 their representative also in the series of the species. 

 Between the two typical series there are so many 

 reciprocal analogies in structure, that nothing fur- 

 ther need be said, seeing that we are in complete 

 ignorance of the manners and habits of those birds, 

 from which, no doubt, satisfactory evidence might 

 be drawn ; certain, however, it is, that nothing is 

 yet known to invalidate the series in which they 

 have been placed. On passing to the two other 

 aberrant columns, we find all those with conspi- 

 cuous crests coming parallel to each other, as Me- 

 galophuS) Musclpeta fldbellifera, and My'iagra fla- 

 mpes ; this latter bird, by its long pointed wings 

 and short tail, being also the type of form of the 

 sub-genus Muscicapa. Lastly, the most aberrant 

 types in each of the three columns which are filled 

 up, are Monacha^ Hyliota, and Muscipeta pecto- 

 raliS) the only birds among the whole which have 

 the narrowest bills. 



We retain the original name of
