ON THE CLASSIFICATION OP BIBDS. 
of Philomela^ represent the typical perfection of this 
subfamily : their own particular circle has not been 
worked out, but it W'ill comprise not only the nightingale, 
hut the white-throated and the black-capped warblers 
of Britain ; these latter assuming much of the appear- 
ance, while they are perfectly analogous to the tits 
(Paim). From these we pass to the genus Phesnieura 
Sw., familiar to every one hy the frequency of our native 
example the redstart (^Jig.136.) ; nearly all the species, in 
fact, have the tail of a 
bright chestnut or rufous 
colour. The tenuirostral 
type appears to us to he 
represented by the SyMa 
galactotes of Europe, which 
is evidently a walking bird. 
and perfectly analogous 
to Fumariue, Motucilla, 
and the other long-legged warblers representing the 
GralMores. 
(73.) The analogies which may be traced between 
this group and many others, are no less striking than 
those of the last. They are, in fact, so numerous, 
that we hardly know where to select our illustrations : 
the best, perhaps, will be to compare this with the 
neighbouring group of true thrushes : we thus find 
the nightingale represented by the famous mocking 
bird of America {OrpheuK) ; the Cnrruca Mm-uloVks 
Sw. hy the typical thrushes ; and the red-tailed rock 
thrushes(iA<rocfKcla),bythered-tailed redstarts. Again, 
on looking to the Sylviarue (the subfamily we have 
just quitted), we see the soft tail of Malunis trans- 
ferred to the reed warblers (Curruca), while the 
wood wrens (^Sylvia) and the nightingales are both 
characterised by even tails : the broad rounded form of 
this member, in CuKcivora and Phcenicura, is another 
very curious analogy ; and the resemblance of Agrabates 
to Fiirriarius is obvious to every ornithologist. 
( 74 .) The Saxicolin.®, or stonechats, represent the
