  Basal 
  view 
  of 
  a 
  large 
  individual, 
  showing 
  the 
  form 
  and 
  lobation 
  of 
  the 
  

  

  body 
  and 
  the 
  structure 
  of 
  the 
  base 
  with 
  the 
  attachment 
  for 
  the 
  

  

  column. 
  The 
  bifurcations 
  of 
  the 
  basal 
  branches 
  indicate 
  that 
  there 
  

  

  were 
  ten 
  ambulacral 
  openings 
  to 
  the 
  interior 
  chambers.

  Lateral 
  view 
  showing 
  the 
  elevation 
  of 
  the 
  body, 
  and 
  the

  surface,

  by 
  the 
  weathering 
  of 
  the 
  exterior.

  The 
  base 
  of 
  a 
  smaller 
  specimen 
  with 
  the 
  form 
  and 
  lobation 
  of 
  the 
  body 
  

   shown 
  in 
  outline. 
  The 
  base 
  of 
  this 
  specimen 
  is 
  comparatively 
  a 
  

   little 
  larger 
  than 
  in 
  the 
  preceding 
  one. 
  The 
  external 
  structure 
  is 
  

   shown, 
  and 
  a 
  portion 
  of 
  the 
  stellate 
  surface 
  at 
  the 
  right 
  hand 
  side 
  

   of 
  the 
  figure. 
  The 
  portion 
  in 
  outline 
  shows 
  the 
  internal 
  chambers 
  

   of 
  the 
  same 
  specimen.

  A 
  portion 
  of 
  the 
  surface 
  enlarged 
  six 
  diameters 
  showing 
  the 
  stellate 
  

   network 
  forming 
  the 
  exterior 
  walls 
  of 
  the 
  chambers. 
  At 
  the 
  junc- 
  

   tion 
  of 
  the 
  numerous 
  ramifications 
  the 
  rays 
  are 
  thickened 
  and 
  

   elevated 
  into 
  a 
  distinct 
  node.

  A 
  vertical 
  section 
  of 
  specimen, 
  fig. 
  1, 
  showing 
  the 
  vertical 
  axis 
  and 
  

   horizontal 
  partitions 
  of 
  the 
  body. 
  The 
  chamber 
  indicated 
  by 
  c, 
  

   appears 
  to 
  be 
  composed 
  of 
  solid 
  plates, 
  occupying 
  a 
  position 
  imme- 
  

   diately 
  above 
  the 
  column 
  attachment, 
  and 
  corresponding 
  to 
  the 
  

   position 
  of 
  a 
  calyx 
  proper. 
  The 
  double 
  character 
  of 
  the 
  exterior 
  

   chamber 
  walls 
  is 
  also 
  shown, 
  with 
  the 
  infolding 
  of 
  the 
  interior 
  

   layer 
  to 
  form 
  the 
  partitions 
  of 
  the 
  chambers.

  and 
  an 
  obscure 
  central 
  cavity,
