  Zoarium 
  small, 
  cylindrical, 
  with 
  4-6 
  zooecia 
  in 
  a 
  series. 
  Zocecia 
  

   hexagonal, 
  contracted 
  below, 
  bounded 
  by 
  a 
  double 
  rim 
  scarcely 
  

   raised 
  ; 
  surface 
  almost 
  flat, 
  raised 
  round 
  the 
  aperture. 
  Oral 
  aperture 
  

   large, 
  with 
  two 
  teeth 
  above 
  and 
  two 
  below, 
  about 
  0\1 
  8 
  millim. 
  wide. 
  

  

  The 
  zooecia 
  and 
  aperture 
  are 
  larger 
  than 
  in 
  any 
  species 
  with 
  

   which 
  I 
  am 
  acquainted 
  : 
  and 
  I 
  find 
  that 
  the 
  size 
  of 
  the 
  aperture 
  is 
  of 
  

   considerable 
  value 
  in 
  the 
  determination 
  of 
  the 
  Cellarice. 
  The 
  oral 
  

   aperture 
  of 
  C. 
  malvinemis 
  is 
  about 
  0*17 
  millim.

   sinuosa

  French 
  coast),
