The subdivisions of the Nearctic are given in Fig. 

 336. They are : 1. California, including the Pacific bor- 

 der from Vancouver Island to the borders of Mexico. 



2. Rocky Mountains, including all the mountains and 

 desert region, and extending into the Mexican plateau. 



3. Alleghanian, including all the United States east of the 

 plains and south of the Great Lakes. 4. Canadian, in- 

 cluding all north of 1, 2, and 3. 



Primary Divisions of Marine Faunas.— Sclater 

 makes of these also six. But in the present imperfect 

 state of knowledge the simpler classification proposed 

 by Gill seems preferable. Gill divides marine faunas 

 into three great realms: 1. North Polar or Arctalian. 2. 

 Tropicalian. 3. South Polar, or Notalian.
