MUSCICAPA (Linnaeus) 
to that sub-genus which immediately follows My'ia- 
gra. All the birds coming under this designation 
have, in comparison to the three last divisions, 
longer and more pointed wings, stronger and more 
equal lateral claws, and shorter and more even tails. 
The bill, also, is materially different from all the 
other sub-genera, and more resembles that of Co- 
nopopkaga : it is small, short, and rather strong, the 
sides being considerably compressed, although the 
base is still broad. These characters are more or 
less developed in different species ; hut they are 
sufficient, even in the most aberrant examples, to 
prevent any ornithologist, with proper attention, 
from confounding this group with any we have yet 
noticed in the family. The tarsi have also this pe- 
culiarity, that although they are often not longer 
than in Myiagra , or in Micscipeta, they are never- 
theless stouter, and the scales which cover them in 
front, instead of being divided, are formed of an 
entire piece. This, although a minute character, is 
yet the most constant, and therefore one of the 
most important. The compression of the hill is 
accompanied by a thickening of the under mandi- 
ble, the gonys of which, instead of being straight, 
is curved upwards ; the bristles at the base, although
