88 PAL^ARCTIC REGION. [CII. IT 



The six Zoological regions of Mr Sclater. 



In the pages that follow I have purposely refrained 

 from a detailed account of the faunas of each ; much that 

 is not to be found in the present section will be found 

 elsewhere. I have here simply abstracted from Wallace 

 and other books a list of the genera absolutely confined to 

 each region, and given a few forms which are highly 

 characteristic of, though not absolutely confined to, each 

 region. 



I. The Palsearctic region. 



This region contains in the first place the whole of 

 Europe with the outlying islands of Iceland in the north 

 and down to the Cape de Verde islands in the south. 

 The north of Africa to the tropic of Cancer is included by 

 Mr Wallace, though others prolong the Palsearctic region 

 further to the south ; the Arabian peninsula is divided 

 into two approximately equal halves by the line of division 

 between the Palsearctic and the Ethiopian region. The 

 whole of the north of Asia including Japan belongs to this 

 region, which reaches the Arabian sea along the coast of 

 Persia. The delimitations of the Oriental region are along 

 the southern slopes of the Himalayas, Afghanistan and 

 Baluchistan going with the Palaearctic. In China the 

 limits of the Palsearctic region are at about Shanghai 

 on the coast.
