not yet been prepared, but on a rough estimate, the percentage of 

 living species in the Eocene does not exceed one, and in the 

 Miocene may amount to 10.

Specific relations with other Tertiary Areas. — I. New 

 Zealand. The accompanying list contains the names of 45 species 

 common to the Older Tertiary of the two areas, from which may 

 be gathered that our Eocene species are largely prevalent in the 

 Oamaru Series of Hutton (Cretaceo-Eocene of Hector), and that 

 our Miocene species are best represented in the Pareora Series.
