Pholadomya subelongata Meek 

 Pinna JBreioeri Gabb 

 Inoceramus subundatus (?) 

 Cinulia obliqua Gabb 

 Perissolax brevirostris Gabb 

 Lunatia, sp. 



Two and three-quarter miles north of Pigeon Point on coast, 

 in conglomerate. 



Turritella chicoensis Gabb 



Half a mile south of mouth of Pescadero Creek. 



Mactra, n. sp. (?) 



Fragment of coral, unidentifiable. 



Bolsa Point, one mile north of Pigeon Point. 



Glycymeris Veatchi Gabb 

 Mactra-like shell 



The beds are of hard shales, sandstone and massive conglom- 

 erates. The conglomerates forming the top of the series are 

 much disturbed ; the shales are apparently the bottom. 



Sand dunes and gravels overlie these Upper Cretaceous beds 

 along the coast, exposing the Chico only in the cliffs in places. 

 The relations of Cretaceous to Tertiary are not plainly shown 

 here, but the two series of beds are supposed to be uncon- 

 formable. 



Stevens Creek. — The Cretaceous beds at Stevens Creek con- 

 sist of interbedded conglomerates and hard black shales, which 

 have furnished these Knoxville fossils. 



Axicella Piochi Gabb 

 JBelemnites 



The fossils were found both in the shale and conglomerate. 

 The shale has broken off in large blocks from the steep walls 

 of the canyon and in these the Aucellae and Belemnites were 

 obtained as well as from rock in place near by. The shale 

 fragments are large and angular, so they must be from the 

 walls of the canyon. Besides the fossils given above an un- 

 identifiable bivalve was found. 



Stanford University. — -Two specimens of JBaeulites chicoen- 

 sis Trask have been found near Stanford University. One 

 came from a hard yellow sandstone, apparently in place, at the 

 north end of a quarry about a quarter of a mile south of the 

 University buildings. The other specimen was found inside 

 of a block of sandstone that was brought up by an intrusion of 

 basalt. The basalt cuts rocks of Miocene age, and this specimen 

 of Baculites may be considered as proof of the presence of 

 Chico underlying the Tertiary deposits in this neighborhood.
