 though their existence is not quite established, the 

 G. Leucocephalw and G. Ftutcus. We must now, 

 however, pass on to the 



FOSSILE GLOBICEPS. 



Globicephalus Cortesi, Cuvier Delphinus Cortesi, Fossile. 



WE shall here shortly allude to a fossile species 

 which was discovered by Cortesi, and arranged in 

 this genus by Cuvier. This was the first of the 

 magnificent discoveries made by M. Cortesi of 

 Plaisance, on the Appennine hills to the south of 

 Fiorenzuola. In 1800, this enthusiastic naturalist 

 procured the fossile bones of an elephant and rhino- 

 ceros on the top of Mount Pulgnasco, one of the 

 hills which descends from the Appennines to the Po , 

 they were almost on the surface. Parallel to Mount 

 Pulgnasco on the east, and separated by the streamlet
