tricts where the genus is strong by a double asterisk, where weak 

 by only one. My numbers, where given, have no pretence to 

 more than a general approximation : for my purpose this is 

 enough ; and I believe they will be found sufficiently near to 

 answer it. 



JVbte 2. — The geographical regions in this Table are : — - 



1. Europe, including the Mediterranean district. North Africa 

 as far south as the southern margin of the Sahara, Syria, Asia 

 Minor, and the shores of the Black Sea. 



2. Asia, north of the Himalayan range, from the Ural moun- 

 tains and Caucasus eastward to the Pacific. 



8. North America east of the Rocky mountains. 



4. North-west America from Behring's Straits to Mexico. 



5. The Chilian region, including the whole of South America 

 to the west of the Andes, the part of Peru in the Andes, part of 

 the South of Bolivia, and the western and southern part of Para- 

 guay, also La Plata, Patagonia, and Terra del Euego. 



6. Australia, including Yan Diemen's Land. I should have 

 wished to divide Australia into the northern and the southern 

 halves ; but as yet our materials are insufficient to allow this to 

 be done. More attention is now bestowed on localities ; and I 

 trust it will not be long before we can fairly allot the difi"erent 

 portions of the Australian fauna. 



7. New Zealand. 



8. Polynesia. In this I include the islands between Australia 

 and Chili, except New Zealand. 



9. Debatable land between North and South America, in- 

 cluding Florida, New Mexico, Mexico, Central America, and 

 part of Columbia, New Granada, and Cayenne. I have added 

 this and the two following columns of debatable land for the pur- 

 pose of as much as possible keeping the elements of the faunas 

 on either side of it free from what may have been a foreign in- 

 fluence. The reader can carry it to the credit of either as seems 

 to him agreeable, or omit it altogether. 



10. Debatable land between the East Indies and Asia, in- 

 cluding the Himalayas, Nepal, Silhet, the Burmese mountains, 

 part of China, &c. 



11. Debatable land between North Africa and the northern 

 frontier of Senegal. 



12. Brazilian region, the parts of South America lying east of 

 the Andes and not above disposed of.
