INTRODUCTION 



Some years ago Prof. Bruce L. Clark, of the University of Cali- 

 fornia, sent me for study a collection of Oligocene crabs obtained in 

 Washington and Vancouver Island by Harold Hannibal for Stan- 

 ford University. The material proved so interesting that an effort 

 was made to gather together all the fossil decapod Crustacea from 

 the Pacific slope which were scattered in museums and in private 

 collections. 



Among the contributors besides the University of California were 

 the following : The Universit}'^ of Oregon, through Dr. Earl L. 

 Packard; the University of Washington, through Dr. Charles E. 

 Weaver and Dr. Katherine Van Winkle Palmer; the California 

 Academy of Sciences, through Dr. B. AY. Evermann and Dr. G. 

 Dallas Hanna; Stanford University, through Mrs. Ida S. Oldroj^d; 

 the San Diego Society of Natural History, through Mrs. Kate 

 Stephens; the Academy of Natural Sciences, Philadelphia, through 

 Dr. H. A. Pilsbry ; the Yale University Museum, through Dr. Charles 

 Schuchert; the Provincial Museum, Victoria, B. C, through F. 

 Kermode and Dr. C. F. Newcombe; T. S. Oldroyd, Palo Alto, 

 California; Dr. F. C. Clark, Santa Monica, California; Marcus 

 A. Hanna, University of Washington; Oscar Gorrell, principal of 

 the public schools, Sutherlin, Oregon; and R. H. Palmer, Palo 

 Alto, California. 



The collections in the National Museum also were placed at my 

 disposal. These consist chiefly of material transferred by the 

 United States Geological Survey, and obtained by Chester W. Wash- 

 burne and other geologists, among them Dr. J. C. Schenk, Dr. Ralph 

 Arnold, Robert Anderson, Dr. J. S. Diller, H. J. Karstner, Dr. G. C. 

 Martin, and Dr. L. F. Noble. Other contributors to the museum 

 collection are C. R. Orcutt and Frank Stephens. 



Aside from the work done by Woodward and Whiteaves on the 

 British Columbia Cretaceous, very little has been written about the 

 fossil Crustacea of the Pacific slope. (See Bibliograph}'^, pp. 

 138-140.)
