  Gregory, 
  1899, 
  wrote: 
  " 
  The 
  name 
  of 
  the 
  species 
  refers 
  to 
  the 
  thick 
  

   form 
  of 
  the 
  zoarium, 
  but 
  the 
  most 
  interesting 
  feature 
  of 
  this 
  bryozoan 
  

   is 
  its 
  tendency 
  to 
  grow 
  in 
  a 
  series 
  of 
  zoarial 
  groups, 
  as 
  if 
  it 
  were 
  a 
  

   very 
  primitive 
  form 
  of 
  Cellulijjora." 
  

  

  There 
  is 
  no 
  reason 
  to 
  separate 
  this 
  species 
  from 
  the 
  group 
  Celluli- 
  

   jwra, 
  the 
  exterior 
  aspect 
  being 
  absolutely 
  identical; 
  the 
  cellules 
  are 
  

   very 
  short 
  and 
  cylindrical.

  Gregory, 
  in 
  1S99, 
  identified 
  this 
  species 
  with 
  Proboscina 
  fasciculata 
  

   Reuss, 
  1845. 
  This 
  is 
  possible, 
  and 
  we 
  refer 
  the 
  reader 
  to 
  page 
  29 
  

   of 
  his 
  catalogue 
  for 
  the 
  synonomy 
  and 
  geological 
  distribution. 
  How- 
  

   ever, 
  it 
  differs 
  from 
  Proboscina 
  zic-zac 
  D'Orbigny, 
  1851. 
  Our 
  speci- 
  

   mens 
  correspond 
  to 
  the 
  figure 
  given 
  by 
  D'Orbigny 
  and 
  we 
  therefore 
  

   cite 
  only 
  this 
  reference.
