IV. THE SOUTH CALIFORNIAN FAUNA. 



So far as known, this fauna has few species peculiar to it. The 

 species are largely members of the more northern faunae that extend 

 far south (indicated by an asterisk), and partly species of the more 

 southern fauna of Lower California and the Gulf of California that 

 range northward beyond the normal limits of that fauna (indicated 

 by a dagger) . Some of the species, however, appear to be peculiar 

 to this district, so far as known, and others have here their chief 

 development or " center of distribution."
