is small and spurious, being hardly half as long as 
the next ; the second is half an inch shorter than 
the third; and this latter, again, is about three- ten tbs 
of an inch shorter than the fourth ; the fourth, fifth, 
and sixth, being all of the same length, and longer 
than any of the others. This sort of wing, without 
any variation, is alike common to Muscicapa, Rhi- 
pidura, Seisura , Myagra, Monacha, and Platys- 
tera; in Hyliota there is a slight deviation; the 
second quill is longer, and the third almost reaches 
the end of the fourth ; this departure from the typi- 
cal structure prepares us for a second modification, 
as seen in the Muscicapa atricapilla of Europe and 
its allies ; the first quill becomes smaller and is not 
one-tliird the length of the second, while the third 
is the longest of all. This structure of wing is much 
more pointed than that of the first we described : it 
has evidently greater power, and we consequently 
find it has been given to a group of birds which are 
known, like our grey flycatcher, to migrate. Were 
it not for the bristled and depressed bill of some of 
those latter, their feet are so unusually strong in 
comparison to those of their congeners, and their 
wings so very similar to those of the Stone-chats, 
that we should be almost tempted to place them 
with the Saxicolinw ; and, indeed, in respect to 
some, we are by no means satisfied to which group 
they naturally belong ; the characters by which we 
propose to denominate them null be subsequently 
stated. In the mean time, it deserves marked at- 
tention, that this close approximation leaves us in
