Genus CROCOPUS. 



This genus contains but one species which m, however, easily 

 divisible into three geographical subspecies with weU-defined char- 

 acteristics which overlap no more than such characteristics generally 

 do where the respective ranges meet. 



This genus, with the exception of Butreron, is the largest of our 

 Indian " Green Pigeons," having a wing of about 7.5 in., whereas none 

 of the others exceed 7 in., and some are under 6. It is also, in one form 

 or another, the most widespread, being found throughout the greater 

 part of the countries with which we are now deahng. 



A very distmctive feature of this bird is its yellow legs and feet, 

 all our other species of this subfamily having red legs and feet.
