ZOOLOGICAL LEGIONS. 
53 
of the great zoological regions of the globe, we find that they 
do not differ so much from the old geographical divisions as our 
first example might have led us to suppose. Europe, Asia, 
Africa, Australia, North America, and South America, really 
correspond, each to a zoological region, but their boundaries 
require to be modified more or less considerably; and if we 
remember this, and keep their extensions or limitations always 
in our mind, we may use the terms “South American” or 
‘ North American,” as being equivalent to Neotropical and 
Nearctic, without much inconvenience, while “African” and 
“ Australian ” equally well serve to express the zoological type 
of the Ethiopian and Australian regions. Europe and Asia 
require more important modifications. The European fauna 
does indeed well represent the Palsearctic in all its main 
features, and if instead of Asia we say tropical Asia we have the 
Oriental region very fairly defined ; so that the relation of the 
geographical and the zoological primary divisions of the earth is 
sufficiently clear. In order to make these relations visible to 
the eye and more easily remembered, we will put them into 
a tabular form: 
Regions. Geographical Equivalent. 
Palsearctic Europe, with north temperate Africa and Asia. 
Ethiopian Africa (south of the Sahara) with Madagascar. 
Oriental Tropical Asia, to Philippines and Java. 
Australian Australia, with Pacific Islands, Moluccas, &c. 
Nearctic.. North America, to North Mexico. 
Neotropical... South America, with tropical N. America and W. Indies. 
The following arrangement of the regions will indicate their 
geographical position, and to a considerable extent their relation 
to each other.
