INTRODUCTION 



The purpose of this paper is to place on record the description and illus- 

 tration of new fossil molluscan species from the Eocene formations of western 

 Washington. For several years the writers have been engaged in an investigation 

 of the Washington Eocene, the results of which are to be published in a strat- 

 -igraphical and faunal history of the Eocene of the Northwest. Extensive 

 collections were made from the Eocene formations of Washington as well as 

 those of Oregon. These were in even- case, where possible, tied into strati- 

 graphic sections. A preliminary study of the faunas was made in the paleon- 

 tological laboratory of the University of California. Later the material was 

 divided into duplicate collections, one of which was retained by the senior writer 

 for study in the paleontological laboratory of the University of Washington 

 and the other by the junior author at Cornell University. Accordingly there 

 has been opportunity for study and comparison with the marine Eocene of 

 California as well as with that of the Atlantic and Gulf. Of the new species 

 recognized as a result of these investigations, sixty-four are described in this 

 report. A list of faunal localities in western Washington has been included. 

 This list is a continuation of the series as published in volume 1, number 1, of 

 the University of Washington Publications in Geology.
