Nearly all of the forms included in the list from the lower 

 horizon of the Wildcat Series, excepting the new species, occur in 

 the Miocene of Coos Bay and other Miocene localities along the 

 coast. It is probable, therefore, that the lower portion of the 

 Wildcat Series is not later than the uppermost Miocene. 



A large number of the species included in the list from the 

 upper horizon have not previously been reported from this series. 

 The list contains species that have been collected from all of the 

 sections described on previous pages. A number of those obtained 

 from the upper portion of the beach section, north of Guthrie 

 Creek, occur commonly in the Pliocene of Santa Barbara and in 

 the Pleistocene of San Pedro. This points toward a rather late 

 Pliocene age for the uppermost portion of the beach section. The 

 Scotia Bluffs, north of Scotia, yielded a fauna very similar to the 

 Merced Series south of San Francisco, a fact which warrants a 

 very close correlation between the two groups of beds.
