BIRDS of this genus have a (lender and weak bill * : 

 noftrils final], a little deprefTed : tongue cloven. 

 The exterior toe joined at the under part to the bafe of the 

 middle one. 



This genus and the laft are blended by Linnaeus, but very 

 properly feparated by Mr. Pennant, as they differ in feveral of 

 their manners. The birds here treated of perch on trees, for 

 the moft part; proceed by leaps, not running f; and feldom 

 emit any noife in flight. They are the mofl numerous of any 

 genUs, and the major part inhabit the warmer regions, where 

 infects of all kinds, their proper food, abound. Many of the- 

 birds included in this chapter feem to belong to the Flycatcher 

 tribe ; and perhaps, on future invefligation, may hereafter prove 

 to be really fuch. 



* Many have a notch at the tip of the upper mandible, bot this character, 

 is not conflant. 



f The Wheat-ears, andibme others, are an exception to this. .
