GENERAL INDEX 
All names in Italics refer, either to the genera and other groups of Extinct 
Animals in Part II. of the. First Volume ; — or to the genera whose distribution 
is given under Geographical Zoology (Part IV.) in the Second Volume; the 
Families and higher groups being in small capitals. All other references are in 
ordinary type. 
The various matters discussed under Zoological Geography (Part III.), are 
indexed as much as possible by subjects and localities. None of the genera 
mentioned in this Part are indexed, as this would have more than doubled the 
extent of the Index, and would have served no useful purpose, because the 
general distribution of each genus is given in Part IV., and the separate details 
can always be found by referring to the region, sub-region, and class.
