Birds of Celebes: Falconidae. 
79 
This species ranges from Timoiiaut and the Moluccas as far as Borneo, 
but it varies locally within this area, the extremes of difference being found in 
Halmahera on the one side, and in Celebes and the Lesser Sunda Islands on 
the other, while some of the Moluccas, such as Bum and apparently Amboina 
(which furnished the type of the species) are inhabited by birds -which seem to 
be intermediate. A little consideration will make it clear that there is no good 
purpose served by applying trinomials to the forms intermediate between two 
races — such names are not only useless and cumbersome, but also misleading 
since they bring with them the idea: here the species has developed into a 
jironounced race! The only places where trinomials may be employed without 
damage are where the extreme racial variations are found. In the case of the 
present species there is no typical subspecies. The extremes and means, as at 
l)resent understood, may be identified in the following manner:
