THE FAUNA OF BRITAIN. 10$ 



be classed as a separate province, since it does not 

 contain a single species peculiar to itself. But, along 

 with Ireland and the South-west of England and 

 Wales, it is distinguished from the remainder of 

 these countries by the almost total absence of what 

 have been called Germanic types. 



A French conchologist, the late Dr. Fischer, dealt 

 with the British molluscan fauna in a somewhat 

 similar spirit (p. 57). He divided the British area 

 into two districts, but these differ from mine in so 

 far as the South-west of England and Wales and the 

 West of Ireland form one ; the remainder of England 

 and Ireland as well as the whole of Scotland the 

 other. His classification is of particular interest, 

 since the first district represents part of a larger 

 Atlantic province, the second a portion of the Ger- 

 manic province of the European sub-region. The 

 latter he looks upon as one of the sub-regions of 

 the great Palsearctic Region. Attention is thus 

 drawn to the intimate relationship existing between 

 the western parts of the British Islands and the 

 Spanish peninsula on the one hand, and between the 

 eastern portions and Central Europe on the other. 



Mr. Jordan's North-Sea-and-Baltic district includes 

 Scotland and the North of Ireland, whilst England 

 joined with the West and South of Ireland forms part 

 of his Celtic province. Both of these districts or pro- 

 vinces belong to Mr. Jordan's greater Germanic 

 Region (p. 302).
