Arrangement of Genera and Species 



In the text of the systematic part which follows, the genera are treated in 

 the order of their geological succession as they appear in the tables of distri- 

 bution, which is not always the same as in the analyses of the genera ; and the 

 species for the most part are similarly arranged.
