 Hng the intricate problems involved. The author states that he 

 has not yet observed the marked " physical break between the 

 Cretaceous and Eocene on the Pacific border."

In this paper the author, who has made a most careful study 

 of and carried extensive researches in the Pacific Coast Region 

 of the U. S. of America, gives us a valuable contribution to the 

 geological history of that region, not only in differentiating the 

 various horizons and faunas presented, but also in describing 

 several new species which he has discovered during his travels 

 in the West. Dr. Stanton has been able to bridge that hiatus 

 between the Eocene and Cretaceous systems by careful stati- 

 graphic methods accompanied by accurate palaeontologica 

 determination. H. M. A.
