  More 
  imperfect 
  skeleton

  obscure 
  remains 
  of 
  the 
  

   head. 
  The 
  indurated 
  contents 
  of 
  the 
  intestine 
  seem 
  to 
  

   preserve 
  impressions 
  of 
  the 
  folds 
  of 
  the 
  spiral 
  valve.

  The

  portion 
  of 
  a 
  large 
  fish, 
  wanting 
  the 
  tail 
  and 
  

   the 
  anterior 
  end 
  of 
  the 
  head, 
  and 
  with 
  much-displaced 
  

   squamation. 
  Large 
  slender 
  fulcra 
  are 
  shown 
  in 
  front 
  of 
  

   each 
  of 
  the 
  paired 
  fins 
  ; 
  and 
  the 
  stout 
  median 
  scales 
  are 
  

   preserved 
  at 
  the 
  base 
  of 
  the 
  lower 
  lobe 
  of 
  the 
  caudal

  Skeleton 
  of 
  the 
  trunk 
  of 
  a 
  smaller 
  fish, 
  with 
  a 
  few 
  

   fragmentary 
  head-bones. 
  The 
  squamation 
  is 
  almost 
  

   destroyed, 
  only 
  a 
  few 
  rhombic 
  scales 
  being 
  shown 
  on 
  the 
  

   flank 
  of 
  the 
  abdominal 
  region. 
  The 
  hypocentra 
  in 
  the 
  

   abdominal 
  region 
  are 
  broad 
  and 
  flattened 
  below 
  ; 
  those 
  in 
  

   the 
  caudal 
  region 
  are 
  smaller 
  and 
  firmly 
  united 
  with 
  the 
  

   robust 
  pedicles 
  of 
  the 
  haemal 
  arches. 
  The 
  free 
  neural 
  

   spines 
  are 
  imperfectly 
  exhibited; 
  the 
  supports 
  of 
  the 
  anal 
  

   fin 
  are 
  remarkably 
  long, 
  and 
  the 
  pelvic 
  basipterygia 
  are 
  

   well- 
  ossified 
  and 
  robust.
