A PLEISTOCENE MOLLUSCAN FAUNA FROM PHILLIPS 

 COUNTY, KANSAS. 



BY G. DALLAS HANNA AND EDWARD C. JOHNSTON.

 (Contribution from the Zoological Laboratory. No. 202.) 



RECENTLY, in looking over some stored fossils, Mr. H. T. 

 Martin, of the University of Kansas Museum, found along 

 with some vertebrates a small series of fossil shells from Long 

 Island, Kan. The vertebrates were collected by E. P. West, 

 and it is probable that the shells were also collected by him, 

 although there was no name on the label. An opportunity to 

 study this material was given the writers by Prof. C. E. Mc- 

 Clung, to whom we are duly thankful. In regard to the topog- 

 raphy and history of the region Mr. Martin was able to give 

 much interesting information. 



A hurried examination of this material showed that it be- 

 longed to a fauna essentially different from that which lives at 

 the present time not far distant from Long Island, in localities 

 where collecting has been done. Most of the Long Island 

 species were not represented in our collections from points 

 nearer than northern United States. 



In order to obtain a more complete series of the shells and 

 data in regard to the horizon in which they occur, a trip was 

 made to the region in October, 1910. We started at Norton, 

 twenty-five miles southwest of Long Island, and descended 

 Prairie Dog creek to that point. Recent shells were collected 

 along the route and fossils at many railroad cuts and exposures 

 along the creek. The white Miocene rocks capping the hills
