CORALS FROM THE CRETACEOUS AND TERTIARY OF CALIFORNIA AND 



OREGON 



BY J. O. NOMLAND 



(Abstract) 



Although a number of corals have been described from the Cretaceous and 

 Tertiary of the Pacific coast, the members of this group have been used only 

 to a limited extent for correlation purposes. The geologic and geographic 

 ranges of this group are discussed on the basis of (lie much enlarged coral 

 fauna now known from this coast. 



EOCENE OF THE LOWER COWLITZ RIVER VALLEY, WASHINGTON 



by charles e. weaver 



Discussion 



Doctor Dickenson stated that Doctor Weaver should be congratulated on 

 this excellent piece of work, which placed the stratigraphy of the Cowlitz 

 basin on such a firm basis. 



Mr. Clarence Waring thought that the faunas from that region showed 

 some basis for separation into horizons, and that they should not be treated 

 as a unit. 



FAUNAL STUDIES IN THE CRETACEOUS OF THE SANTA ANA MOUNTAINS OF 

 SOUTHERN CALIFORNIA 



BY EARL L. PACKARD 



(Abstract) 



The fauna from the Santa Ana Mountains is more closely related to that of 

 the typical Chico than to that of the Horsetown. The peculiarities of this 

 southern fauna are attributed to the difference between the environment of 

 the Sacramento Valley and that of the Santa Ana Mountain basin of deposi- 

 tion.
