  the

  one 
  of

  This

  a 
  portion 
  of 
  a 
  leaf 
  blade 
  of 
  some 
  monocotyle-

  These 
  specimens 
  are 
  evidently 
  fragments 
  of 
  monocotyledons, 
  

   which 
  may 
  be 
  placed 
  in 
  the 
  genus 
  Cyperites 
  for 
  convenience, 
  

   although 
  they 
  might 
  equally 
  well 
  be 
  considered 
  as 
  belonging 
  to 
  

   the 
  Palms.
