Introduction 



Although several species of corals have been described from the 

 Pacific Coast Cretaceous and Tertiary, the members of this group have 

 been used only to a limited extent for correlation purposes. The 

 present paper is an attempt to present a discussion of the Pacific 

 Coast corals in such form that this group may be of larger use to the 

 palaeontologist and to the stratigraphic geologist. A number of new 

 species of West Coast corals available to the writer in various collec- 

 tions are here described.
