THE RAPTOKEIS OF THE PUyJAIi. 



23? 





Ken to the Genera of the Itaptores. 



In the Key to tho fieneva of the TyP^^' letters from a to r have been 

 used to denote various peculiarities merely to save repetition. 



Through this Key — 



a. refers to peculiarity of nostril 



,, tail 



,, neck 



„ primaries with reference to secondaries 



,, claws 



,, primaries with reference to tail 



,, crest 

 h. „ „ „ „ tarsus 



and so on. For instance, in the case of the genus -Hi'jraeiMs in which the 

 primaries exceed the secondaries by more than length of tarsus the claws 

 are much curved, hind claw longest (as in the case of Atjuila), instead of 

 repeating the whole characteristic, 1 merely say *' d and e as in Aquila " 

 under which genus it has already been given. 



The same letter, wherever it occurs, always applies to the same charac- 

 teristic in the Key to the genera.
