Each of these areas is characterized by the presence 

 of certain species which do not live in the others, and 

 the absence of other species peculiar to the adjoining 

 Faunae. Other species, though not restricted to one, 

 conform more or less closely to the geographical limits 

 of two or more of these life areas. Without stopping to 

 speculate upon the causes which, severally or in com- 

 bination, have operated to bring about this arrange- 

 ment, let us consider each of these areas in detail, 

 pointing out its faunal peculiarities and relations to the 

 others. 



The reptilian fauna of California, as at present known, 

 is composed of seventy-one species and subspecies. The 

 following table shows the area or areas which each of 

 these is known to inhabit:
