  A 
  small 
  fish 
  from 
  the 
  Bavarian 
  Lithographic 
  Stone, 
  now 
  in 
  

   the 
  Dresden 
  Museum, 
  may 
  possibly 
  be 
  an 
  immature 
  example 
  of 
  

   this 
  species, 
  but 
  is 
  not 
  certainly 
  determinable. 
  It 
  exhibits 
  no 
  

   ossifications 
  in 
  the 
  notochordal 
  sheath, 
  and 
  is 
  provisionally 
  named
