  Structure. 
  — 
  The 
  branches 
  figured 
  by 
  D'Orbigny 
  are 
  of 
  young 
  speci- 
  

   mens; 
  as 
  they 
  are 
  thin, 
  they 
  appear 
  long. 
  The 
  older 
  branches 
  formed 
  

   of 
  a 
  greater 
  number 
  of 
  tubes 
  have 
  a 
  broader, 
  thicker 
  aspect; 
  the 
  

   zoarium 
  appears 
  like 
  a 
  circular 
  stem 
  bearing 
  short 
  pinnules 
  in 
  all 
  

   directions. 
  The 
  base 
  is 
  a 
  circular 
  disk, 
  little 
  expanded.
