ZOOLOGICAL GEOGRAPHY. 



[PART III. 



Coleoptera. — Of about 80 families into which the Coleoptera are divided, all the 

 more important are cosmopolite, or nearly so. It would therefore unnecessarily occupy 

 space to give tables of the whole for each region. 



Land Shells. — The more important families being cosmopolite, and the smaller 

 ones being somewhat uncertain in their limits, the reader is referred to the account of 

 the families and genera under each region, and to the chapter on Mollusca in the con- 

 cluding part of this work, for such information as can be given of their distribution.
