twenty years ago a specimen of Hyaenognathus, a peculiar dog like 

 Borophagus of the Blanco Pliocene, was found associated with Ischy-

 formation now presumed to be Tulare. 



The fauna of the Tulare-Etchegoin section on the western border 

 of the San Joaquin Valley is as follows :

In the Pinole Tuff-Orincla section scattered remains have been 

 found at a number of localities, but the best representation of the 

 fauna found at any one station is that secured from the Pinole Tuff 

 and Orinda on the border of San Pablo Bay. In these strata there 

 have been obtained the following forms: 7
