We have now traversed tie whole of that great 
circle which is composed of the sub-family Mascica- 
pinw. We commenced with the genus Rhipidura , 
and then proceeded successively through those of 
Monacha, Megalophm , Todus, and Mmcicapa, 
dwelling upon all the minor circles they contained, 
and pointing out the graduated chain of connexion 
between each. We have endeavoured to demon- 
strate the truth of our propositions at every step by 
as refined a species of analysis as we possibly could 
make. But our task in regard to this great circle 
is not yet done ; for we have not yet shown in what 
manner the Muscicapinw, as a whole, actually form 
a circle. We entered it at one point, which was 
Rhipidura , and having traced it as far as Musci- 
tapa , it yet remains to be proved that these two 
groups unite, so that the circle is actually formed, 
and that the series returns into itself. We are, in 
other words, to return by a different route to 
the point from whence we started : this point was 
the genus Rhipidura. The question then is, in 
what manner is this genus united to Mmcicapa ? 
How is the junction made, and the circle closed ? 
We will leave this to the observation of the reader 
with little or no comment. Let him turn to the 
description and figure of our Myadestes genilarlis, 
then look upon that of Muscicapa erytkaca, and he 
will at once perceive no two birds of two connecting 
genera can he more closely allied : their very aspect 
alone bespeaks their connexion. The only doubt 
that remains on our mind is, whether the latter is 
not in reality a second species of Myadestes ! rather
