Note. — Owing to the fact that the Tertiary fossils of the Pacific coast 

 have not been studied so thoroughly as those of the Atlantic slope, we 

 cannot always speak with confidence in regard to their age. Hence it is 

 probable some of the species included in this list may not belong j)roperly 

 to the Miocene. The apparent identity of two species from near the mouth 

 of Columbia River {Niicula Conradi {■=:divaricata, Conr , not Hinds), and 

 Mactra alharia, Conrad), with forms found associated with Ammonites and 

 BacuUtes at Chico Greek, Butte County, California, leaves room for doubts 

 whether some of these supjiosed Miocene beds may not be even older than 

 Tertiary. Until these doubtful questions can be cleared up by the publica- 

 tion of the valuable results of the Geological Survey of California, it has 

 been thought desirable to include in the Miocene list all the species from 

 that region originally referred by Mr. Conrad, and others, to the Miocene 

 epoch, with the exception of a few forms now known not to belong to that 

 epoch.
