  does 
  not 
  seem 
  to 
  be 
  any 
  denticle. 
  Another 
  incrusting 
  species 
  with 
  

   cells 
  more 
  or 
  less 
  erect, 
  as 
  in 
  Cellepora, 
  and 
  with 
  a 
  very 
  large 
  

   aperture 
  (about 
  0*25 
  millim. 
  wide), 
  contracted 
  in 
  the 
  middle 
  and 
  

   expanded 
  below, 
  as 
  in 
  Lepralia 
  lata, 
  may 
  be 
  new, 
  as 
  1 
  have 
  been 
  

   unable 
  to 
  identify 
  with 
  it 
  any 
  described 
  species. 
  There 
  are 
  also 
  

   some 
  pieces 
  of 
  Retepora, 
  which 
  might 
  be 
  R. 
  robusta, 
  Hincks, 
  or 
  R. 
  

   porcellana, 
  MacGr. 
  

  

  The 
  specimen 
  figured 
  in 
  PI. 
  VIII. 
  fig. 
  22 
  is 
  probably 
  a 
  Smittia. 
  

   The 
  distal 
  ends 
  of 
  the 
  zooecia 
  are 
  very 
  much 
  raised, 
  giving 
  the 
  colony 
  

   the 
  appearance 
  of 
  Diastopora.
