ISTKODUCTIOX. IX 



Of Vol. II. of the ' Hand-list,' which contains the Parrots and 



Picarian Birds, Sir Eay Lankester gives the estimate, in 1900, as 

 follows : — 



G-enera454; Species 2861. 



I believe that some mistake must have been made in the number 

 of genera, as I estimate the number of genera at the present time to be 

 449, and the spec-ies 3099, as shown by the following Table : —
