(10) A long erosion interval during which short streams consequent on the 

 lava slope cut through the andesitic lava into the softer underlying deposits. 

 Of these deposits the softest is the Sutter. The pass betvs^een the towns of 

 West Butte and Sutter City was cut in this material. The "secondary craters" 

 described in the Marysville Buttes Folio appear to be erosion valleys formed 

 in the Sutter formation by subsequent tributaries of consequent streams. 



In conclusion, there does not appear to be any formation in the Marysville 

 Buttes except the Tejon Eocene strata which could possibly be the equivalent 

 of the lone of the Sierran foothills. It has been shown above that these 

 Eocene strata are the offshore equivalents of the inshore lone. 



FAUNA OF THE FERNANDO FORMATION OF LOS ANGELES, CALIFORNIA 

 BY CLARENCE L. MOODY 



(Ahstract) 



An excavation near the center of the city of Los Angeles in 1913 brought to 

 view a fossiliferous stratum about 15 feet from the surface which yielded a 

 large marine moUuscan fauna. Collections were made by Mr. J. Z. Gilbert, of 

 the Los Angeles High School, and the material was intrusted to the University 

 of California for studj'. 



The fauna contains a number of forms of boreal habitat, while not a few 

 subtropical species are represented. About 15 per cent of the fauna is extinct. 

 Restricted Pliocene species are Thracia trapezoides Conrad, Turris merceden- 

 sis Martin, Natica orMcularis Nomland, Pecten healeyi Arnold, Pecten opuntia 

 Dall, and Pecten lyellus Conrad, beside ten species regarded as new. 



The fauna has affinities with the Middle Fernando of Santa Clara Valley 

 and with the San Diego Pliocene of San Diego and San Pedro. It seems to 

 represent a higher zone in the Pliocene Fernando than has heretofore been 

 recognized. 



At the conclusion of the reading of the papers the meeting adjourned 

 and the members of the Paleontological Society attended tlie dinner of 

 the Le Conte Club at the Stanford Union.
