Santa Barbara. The uppermost Pliocene in southern Cali- 

 fornia, in the old Santa Barbara embayment from Point Con-

 Santa Barbara zone^ which term seems to be acceptable. The 

 fauna of this horizon, from the beds at Santa Barbara, and 

 Dead Man Island (San Pedro), chiefly collected and described
