  'displaying

  The 
  neural 
  spines 
  are 
  free 
  as 
  far 
  as 
  

   the 
  middle 
  of 
  the 
  caudal 
  region, 
  but 
  then 
  become 
  fused 
  

   with 
  the 
  corresponding 
  arches. 
  The 
  ribs, 
  though 
  robust, 
  

   do 
  not 
  extend 
  to 
  the 
  ventral 
  border 
  of 
  the 
  trunk. 
  The 
  

   haemal 
  spines 
  in 
  the 
  caudal 
  region 
  meet 
  their 
  supporting 
  

   arches 
  at 
  a 
  considerable 
  angle, 
  are 
  fused 
  with 
  them, 
  and 
  

   exhibit 
  a 
  small 
  triangular 
  expansion 
  anteriorly 
  below 
  the 
  

   point
