  An 
  exactly 
  similar 
  variety 
  to 
  the 
  one 
  figured 
  

   occurs 
  from 
  Bairnsdale, 
  as 
  well 
  as 
  varieties 
  with 
  the 
  avicularium 
  in 
  

   the 
  mouth

  punctured 
  all

  In 
  the 
  Hount-Gambier 
  specimen 
  the 
  oral 
  aperture 
  is 
  quite 
  at 
  the 
  

   distal 
  extremity 
  of 
  the 
  zooecium, 
  and 
  is 
  rather 
  larger 
  than 
  in 
  the 
  

   specimen 
  figured 
  by 
  Mr. 
  Busk 
  in 
  the 
  ' 
  Crag 
  Polyzoa,' 
  but 
  smaller 
  than 
  

   in 
  the 
  recent 
  specimen 
  figured 
  by 
  Mr. 
  Hincks. 
  

  

  In 
  the 
  Australian 
  specimen 
  there 
  are 
  neither 
  zocecial 
  avicularia 
  

   nor 
  ovicelJs. 
  The 
  suboral 
  avicularia 
  are 
  small.

  The 
  

   fragment 
  is 
  but 
  small 
  ; 
  but 
  the 
  cells 
  are 
  apparently 
  heaped 
  together 
  

   in 
  the 
  usual 
  Cellepora 
  fashion.

  Zoarium 
  cylindrical, 
  with 
  six 
  zocecia 
  in 
  a 
  complete 
  series. 
  Zooecia 
  

   smooth,

  Oral 
  aperture 
  much 
  depressed, 
  horseshoe- 
  

   shaped, 
  slightly 
  contracted 
  towards 
  the 
  proximal 
  edge, 
  which 
  is 
  

   straight. 
  On 
  each 
  side 
  in 
  the 
  depression 
  a 
  small 
  opening, 
  which 
  

   may 
  have 
  been 
  avicularian.

  Zoarium

  in 
  Eschara-form, 
  with 
  about 
  eight 
  cells 
  in 
  a

  Zooecia

  aperture 
  large, 
  rounded

   more

  In 
  one 
  specimen, 
  which 
  I 
  believe 
  to 
  be 
  of 
  this 
  species, 
  the 
  cells 
  are 
  

   much 
  longer 
  and 
  the 
  mouth 
  is 
  much 
  more 
  square, 
  as 
  the 
  corners 
  at 
  

   the 
  base 
  of 
  the 
  aperture 
  are 
  rounded 
  off 
  ; 
  and 
  it 
  then 
  looks 
  much
