IV. The Lusitanian Region. 



This region includes the southern half of the British Isles, the coasts of France, Spain 

 and Africa, about as far as the Canary Islands. It is, of course, closely related to the 

 Mediterranean Region, but that sea contains so many forms which appear to be peculiar 

 to it that it appeared best to regard it provisionally as a distinct region.
