NOTES ON THE PALEONTOLOGY OF LEWIS 

 AND GILMER COUNTIES. 



By W. ARMSTRONG PRICE. 



INTRODUCTION. 



The following preliminary report on the invertebrate fos- 

 sils of Lewis and Gilmer Counties contains a summary and 

 table of the faunal horizons known to outcrop in the area, 

 with a description of the content of the fauna of each, as rep- 

 resented by the collections studied, the relationships and dif- 

 ferences which the faunas present to each other being pointed 

 out, and finally the stratigraphic range and areal distribution 

 of the fossils listed are given in a table supplemented by a 

 register of the localities in the area under investigation from 

 which fossils were collected. 



The beds which were found to contain fossils nowhere 

 reach the surface of the ground within the boundaries of Gil- 

 mer County, as was determined by D. B. Reger in his study 

 of the geology of the two counties, nor are fossils known to
