echinoderms. The Lower Minor Zone is known as the Scutella gahhi zone. 

 The zone above this will be known as the Astrodapsis tumidus, n. var., Zone. 

 The faunas of these two minor zones are very similar outside of the echino- 

 derms. 



The Upper Major Faunal Zone is quite distinct from the Lower Major Zone ; 

 not only are the echinoderms different, but a large percentage of the species 

 found in this zone have not been found in the lower. Ninety-one species have 

 been obtained from this zone, 63 species of which are not found in the Lower 

 Major Zone. This Upper Faunal Zone is also divisible into minor faunal zones. 

 At least three of these minor faunal zones are recognizable. Here, again, the 

 most characteristic species of each zone are the echinoderms. 



The fauna from the lower part of the Upper San Pablo Series (the Upper 

 Major Faunal Zone) is to be correlated with the Santa Margarita of Salinas 

 Valley and Coalinga. No fauna from the southern part of the State or any 

 other region has as yet been recognized with certainty as equivalent to the 

 fauna of the Lower Major Zone of the San Pablo Series. 



TERRESTRIAL OLIGOCENE OF THE BA8IN REGION AND ITS RELATION TO 

 THE MARINE OLIGOCENE OF THE PACIFIC COAST PROVINCE

FAUNAL RELATIONS OF THE SAN LORENZO OLIGOCENE TO THE EOCENE IN 



CALIFORNIA 



BY ROY E. DICKERSON 



{Abstract) 



Three species found in the San Lorenzo formation are identical with Tejon 

 forms, and five appear to be closely related to Eocene species. The evidence 

 confirms Arnold's determination of the age of this formation as Oligocene.

LOWER MIOCENE OF WASHINGTON 

 BY CHARLES E. WEAVER 



(Abstract) 



The marine Tertiary of western Washington consists of three distinct units, 

 each of which possesses a distinctive fauna and a lithologic character peculiar 

 to itself. They are separated from one another by well marked unconformities. 

 These formations are Tejon, Lower Miocene, and Upper Miocene. These broad 

 generalizations apply to all portions of the western part of the State. 



The Lower Miocene, on a stratigraphical basis, can not be subdivided. It 

 consists of sandstones and shales, which, when traced, areally grade into one
