  Zoarium 
  in 
  Lepralia-iorm, 
  zooecia 
  subhexagonal 
  to 
  ovoid, 
  surface 
  

   with 
  transverse 
  lines. 
  Ovicells 
  globular, 
  very 
  small, 
  not 
  double 
  the 
  

   diameter 
  of 
  the 
  oral 
  aperture. 
  Oral 
  aperture 
  formed 
  at 
  the 
  distal 
  

   end 
  of 
  a 
  semicircle, 
  0*13 
  millim. 
  in 
  diameter, 
  with 
  a 
  broad 
  sinus 
  at 
  

   the 
  proximal 
  end. 
  A 
  raised 
  triangular 
  avicularium 
  at 
  one 
  side 
  a 
  

   little 
  below 
  the 
  mouth. 
  This 
  corresponds 
  in 
  many 
  particulars 
  with 
  

   Cellepora 
  pumila 
  and 
  0. 
  inornate, 
  Gabb 
  and 
  Horn, 
  but 
  the 
  shape 
  of 
  

   the 
  aperture 
  is 
  formed 
  by 
  two 
  definite 
  arcs, 
  and 
  the 
  ovicells 
  are 
  not 
  

   acuminate.

  Zooecia 
  oval 
  or 
  elongate, 
  raised 
  at 
  the 
  distal 
  end 
  ; 
  oral 
  aperture 
  

   rounded 
  with 
  a 
  broad 
  sinus 
  below, 
  surrounded 
  by 
  a 
  raisedborder 
  which 
  

   encloses 
  the 
  two 
  lateral 
  avicularia 
  at 
  the 
  sides 
  of 
  the 
  aperture. 
  

   There 
  is 
  a 
  slight 
  depression 
  in 
  the 
  border 
  just 
  below 
  the 
  sinus; 
  

   this 
  is 
  evidently 
  the 
  remains 
  of 
  an 
  avicularium.

  Zooecia 
  distinct, 
  raised, 
  broadly 
  ovate 
  ; 
  surface 
  granular 
  and 
  per- 
  

   forate, 
  with 
  a 
  small 
  avicularium 
  on 
  one 
  side 
  a 
  little 
  below 
  the 
  

   orifice 
  ;

  rounded 
  on

  edge,

   with 
  a 
  distinct

  The

  of 
  the

  is 
  not 
  so 
  acuminate 
  as 
  in 
  Mr. 
  Hincks's 
  

   figure 
  from 
  Bass's 
  Straits 
  ; 
  but 
  this 
  is 
  not 
  a 
  constant 
  character, 
  as 
  

   some 
  cells 
  are 
  acuminate 
  while 
  others 
  are 
  round, 
  and 
  I 
  have 
  speci-

  none
