2" in length, round the curve, dispels all further doubt 

 and you know j^^our specimen is undoubtedly a Golden 

 Eagle. 



After a very little practice it will not be necessary to go through 

 the process of elimination and the specimen will be placed in its 

 proper genus at the first glance. In the above example it will be 

 seen that the specimen selected is of a Type that contained other 

 genera with very similar characteristics, so we will try another and a 

 simpler one. 



A very large bird, with tarsi feathered and a heardj of stiff bristles 

 depending from the chin. Straight off you have the genus 

 Gypaetus and since there is only one species representing this 

 genus, your specimen is Gypaetus harhattis, the Lammergeyer. 



By placing all the different genera with a common characteristic 

 into one Type, it reduces one's search from some 55 to 14 species, 

 by merely looking at the head, feet or beak, as the largest Type, 

 viz. : — " G," has 14 species, whereas o have only one species each, 

 and having found your Type you know exactly how many genera 

 and species have been automatically eliminated and how many 

 remain. 



I now proceed to give the keys for, (a) the Types and (h) for the 

 genera and species.
