  Three 
  imperfect 
  much 
  crushed 
  and 
  distorted 
  specimens, 
  

   labelled 
  " 
  Leptolepis 
  filipennis

  by

  doubtfully 
  

   ascribed 
  to

  The 
  squamation

  not 
  

   shown

  the 
  ver- 
  

   tebras 
  are 
  so 
  much 
  crushed 
  that 
  they 
  have 
  the 
  appearance 
  

   of 
  being 
  relatively 
  deeper.
