From Seven-Mile Beach the Merced series extends 

 southeast in the direction of strike to Milbrae. From 

 there to Redwood City the underlying metamorphics are 

 exposed. South of Stanford University the foothills are 

 fossiliferous and show the presence of this formation. It 

 is also shown above Searsville in the lower part of the 

 ravines running into the valley of San Francisquito Creek 

 from the west and south. 



Whitney * notes the presence of several hundred feet 

 of this formation on the north flank of the Palo Scrito 

 Hills. 



It seems possible that most of the beds from which 

 older Pliocene fossils have been reported will be found 

 to correspond with this series. Dr. Lawson believes that 

 the strata which he recently described as the "Wild Cat 

 Series"! in Humboldt county may be correlated with 

 the Merced series. Thus the fauna reported from Kirk- 

 er's Pass and Green Valley, Contra Costa county; Santa 

 Rosa and Russian River, Sonoma county; would suggest 

 the presence of the Merced series. 



Relations. — The relation between the Merced and Mon- 

 terey series was best seen where the strata of the Soquel 

 basin rest upon the Monterey series so abundant north of 

 Santa Cruz. A little north of Surfside, a suburb of Santa 

 Cruz, the contact is well exposed, the line being marked 

 by a line of scattered pebbles of older igneous and chert 

 rock. The beds have a low dip south and are conform- 

 able. Going toward the lighthouse the beds are crossed 

 in ascending order. Just above what has been taken as 

 the line of contact the beds are indistinguishable from the 

 most characteristic white shale. Ascending the series 

 the rock changes imperceptably from the characteristic,
