MYIAGRA. 
It would be vain, in tlie 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 Myiagra 
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- 
galopkus, Muscipeta JiabeUifera, and Myiagra Jla- 
vipes ; 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
