INTRODUCTION 



In an earlier paper 1 the writer has summarized the known corals 

 of the Pacific Coast Cretaceous and Tertiary. More recently a large 

 and important coral fauna has been described by Dr. T. W. Vaughan 2 

 from the Pliocene of Carrizo Creek in the southern part of California. 

 Since the appearance of these publications a few new species have been 

 discovered and other forms have become available. These species are 

 described in the present paper. 



Heretofore by far the greater proportion of corals have been de- 

 scribed from the Tejon Eocene. It is worthy of note that two of the 

 new species here described are from the Oligocene. Several other 

 forms are known to be present in the Oligocene faunas, but the only 

 material obtained up to the present time is not sufficient for specific 

 description.
