"Whether all or part of the faunal stages of th< j Monterey 

 series be made equivalent to the Lower Miocene, th< j Oligocene 

 or divided between them, in the vicissitudes of the history of 

 long-distance faunal correlation, the series here studied repre- 

 sents a natural stratigraphic unit, with characteristic and related 

 faunal elements, and clearness and simplicity demand that 

 throughout this province of deposition it be designated by a single 

 provincial name. The term Monterey in the form Monterey 

 series has been established by priority and consistent usage and 

 its use is urged as the general designation for deposits of this 

 province and depositional cycle.
