2 Hi MIOCENE PERIOD. [Ch. XV. 



This subject requires fuller investigation, and it would be 

 highly interesting if the Montpellier beds should be found to 

 indicate a passage from the fossils of the Miocene type to those 

 of the older Pliocene. We are fully prepared for the dis- 

 covery of such intermediate links, and \ve have endeavoured to 

 provide a place for them in the classification proposed in the 

 fifth chapter *.
