  GEOLOGY. 
  

  

  Since 
  the 
  publication 
  of 
  the 
  preceding 
  list 
  of 
  the 
  

   Vicksburg 
  fossils, 
  it 
  has 
  been 
  found 
  that 
  some 
  of 
  these 
  

   fossils 
  should 
  be 
  referred 
  to 
  different 
  genera; 
  priority 
  of 
  

   description 
  rendering 
  it 
  proper, 
  Mr. 
  Conrad 
  proposes 
  to 
  

   restore 
  the 
  original 
  names. 
  The 
  following, 
  therefore, 
  

   must 
  give 
  way 
  to 
  the 
  terms 
  first 
  applied 
  by 
  earlier 
  

   naturalists.
