MUSCICAPA. 197 



while those retained under the name of Miucipeta 

 seem to be equally spread over Asia and Africa; 

 although we hare not yet seen any from New 

 Holland. Having now prepared the reader to 

 understand the general nature of the group before 

 us, we shall at once proceed to its divisions or sub- 

 genera, distinguishing them by the following names : 

 1. Cryptolopha; 2. Muscipeta ; 3. Myiagra ; 

 4. Muscicapa ; and, 5. Hyliota. The first, fourth, 

 and fifth form the aberrant group, already distin- 

 guished from those two which are typical, by their 

 more narrowed bill, by the superior length or 

 strength of their feet, and by the terminal half of 

 the bill being laterally compressed: a structure 

 which carries with it a proportionate increase of 

 strength and thickness in the under mandible, so 

 that its ridge or gonyx is often curved upwards. la 

 the typical sub-genera neither of these latter charac- 

 ters are seen ; the whole of the bill is depressed, 

 and the under mandible is very flat
