Pleistocenic Faunas. 



The Pleistocenic marine fauna is largely identical with the recent 

 fauna, though often having a different distribution. Only a few 

 species are here given. (See the paper by J. H. Wilson for the 

 Atlantic, and Ralph Arnold for the Pacific coast. For the Fauna 

 at Scarboro see Scudder, and for the Loess fauna Shimek.) 



The following localities are referred to: 



(a) Atlantic coast (Sankaty head, etc., and the clays of New 



England ) . 



(b) Port Kennedy, Pa., cave fauna. 



(c) Scarboro heights and vicinity of Toronto. 



(d) Mississippi valley Loess. 



(e) Pacific coast region.
