   There 
  is 
  a 
  sinus 
  in 
  the 
  round 
  aperture 
  ; 
  but 
  I 
  am 
  not 
  quite 
  sure 
  

   whether 
  this 
  is 
  a 
  primary 
  or 
  secondary 
  character. 
  

  

  The 
  transverse 
  bars 
  without 
  cells 
  and 
  the 
  suboblong 
  fenestras 
  thus 
  

   caused 
  give 
  the 
  colony 
  the 
  appearance 
  of 
  some 
  of 
  the 
  Fenestellidce. 
  

  

  The 
  shape 
  of 
  the 
  zocecia 
  and 
  avicularia 
  is 
  the 
  same 
  as 
  in

  This

  I 
  have 
  already 
  pointed 
  out 
  that 
  probably, 
  on 
  account 
  of 
  the 
  shape 
  

   of

   should 
  be 
  formed 
  into 
  a 
  subgenus

  and 
  the

  should 
  be 
  

   added 
  to 
  the

  1 
  am 
  not, 
  however, 
  inclined 
  to 
  think 
  that 
  they 
  

   will 
  ultimately 
  find 
  their 
  place 
  with 
  Monoporella, 
  and 
  therefore 
  

   provisionally 
  leave 
  this

  Cellepora.

  Addendum. 
  

  

  Shortly 
  after 
  the 
  completion 
  of 
  this 
  paper, 
  Miss 
  Jelly 
  found 
  in 
  her 
  

   collection 
  from 
  S.W. 
  Victoria 
  some 
  specimens 
  which 
  had 
  not 
  been 
  

   submitted 
  to 
  me. 
  As 
  they 
  are 
  of 
  considerable 
  interest, 
  I 
  add 
  a 
  

   description 
  of 
  them 
  as 
  a 
  note 
  to 
  this 
  paper, 
  so 
  as 
  to 
  conclude 
  the 
  

   series 
  on
