732 Mr. H. C. Robinson on Birds collected on the 



from the Indo-Malayan region that are examined, the more 

 it is borne in on one that no more than one species can be 

 maintained. Of the above two specimens one is an almost 

 typical H. armstrongi^ while the other is typical H. humii. 



Thongh the species in a wide sense covers a very large 

 area, it must be remembered that it is with hardly any ex- 

 ceptions a purely coastal form which is rarely found at any 

 distance from the sea. The whole area of distribution may 

 therefore be regarded as practically continuous, in that no 

 barrier of even so much as a hundred miles of sea intervenes 

 between the most widely separated localities inhabited by the 

 species. It is, therefore, quite illogical to divide the species 

 into several local races, and then call in the theory of 

 migration to explain the undoubted fact that two or more 

 of the forms are frequently found existing side by side.
