sands, one sees very little or no difference in the material along the 

 streams and that on the divides between the streams. Furthermore, 

 there are no pebbles of such size as to warrant the name "bowlder." 

 The largest water-worn fragments are less than a foot in diameter. 

 This, together with the fact noted by Shaler 1 , that the creeks along 

 the Coastal margin are more often parallel with the coast line 

 than perpendicular to it, and, therefore, could not have been the 

 result of glacier scourings as in Maine, justify the assertion that 

 glacial influence did not extend in any marked degree so far south 

 as to South Carolina; indeed, it may be said that glacial influence 

 here was almost if not quite imperceptible. 



IV. TABLES OF SOUTH CAROLINA PLEISTOCENE 

 FOSSILS, WITH DATA TO ATTEMPT AN INTER- 

 PRETATION OF ENVIRONMENTAL CONDI- 

 TIONS UNDER WHICH SUCH 

 FOSSILS LIVED. 



i. EXPLANATION OF TABLES. 



These tables have been made to include, as nearly as possible, all 

 Pleistocene molluscan fossils from South Carolina. Not much atten- 

 tion has been paid to vertebrate fossils of this age in the State, though 

 such have been found on Ashley River in great abundance and 

 elsewhere in some quantity. This is perhaps the largest list of Pleis- 

 tocene mollusca that has up to this time been published from the 

 State, including about 180 species, and representing about no 

 genera or genera and subgenera combined. Much time and labor has 

 been spent in ascertaining the various facts regarding each species ; 

 and, however far astray the writer may go in drawing conclusions 

 from his tables, he feels confident that the tables represent the facts 

 in the case so far as they can at present be ascertained. 



In regard to the tables, first, after the name of the species comes 

 the column to show whether or not it is in our own Vanderbilt Uni- 

 versity Collection ; if it is the letter V is found opposite its name. 

 Next are the columns to show the localities in the State where each 

 species has been found. Young Island (Simmons Bluff in the litera- 

 ture) is the most noted locality, though the Stono River beds afford 

 almost as many species. The localities have been arranged in accord-
