  The 
  zoarium 
  consists 
  of 
  zocecia 
  in 
  a 
  single 
  layer 
  forming 
  a 
  hollow 
  

   cylinder 
  about 
  2-5 
  millim. 
  diameter 
  (probably 
  it 
  has 
  grown 
  over 
  the 
  

   round 
  stem 
  of 
  some 
  seaweed). 
  Zocecia 
  in 
  irregular 
  longitudinal 
  rows, 
  

   divided 
  by 
  a 
  much-raised 
  border 
  ; 
  irregularly 
  oblong 
  with 
  parallel 
  

   sides 
  or 
  rhomboidal 
  surface 
  coarsely 
  granulated 
  and 
  perforated, 
  below 
  

   the 
  aperture 
  a 
  narrow 
  acute 
  avicularium 
  directed 
  downwards. 
  Oral 
  

   aperture 
  rounded 
  on 
  the 
  distal 
  end, 
  proximal 
  with 
  a 
  large 
  rounded 
  

   sinus 
  ; 
  in 
  some 
  cases 
  the 
  aperture 
  is 
  much 
  contracted 
  above 
  the 
  sinus 
  ; 
  

   1 
  millim. 
  wide, 
  0*9 
  long. 
  Sometimes 
  the 
  distal 
  border 
  extends 
  as 
  a 
  

   bar 
  above 
  the 
  middle 
  of 
  the 
  aperture, 
  so 
  that 
  the 
  opening 
  appears 
  

   divided 
  into 
  two. 
  

  

  This 
  much 
  resembles 
  Lepralia 
  subimmersa 
  and 
  anceps, 
  MacGilli- 
  

   vray 
  (Prodr. 
  of 
  Zool. 
  p. 
  23, 
  Decade 
  iv.), 
  but 
  differs 
  from 
  the 
  former 
  

   in 
  the 
  shape 
  and 
  direction 
  of 
  the 
  avicularium, 
  and 
  from 
  Smittia 
  

   anceps 
  in 
  having 
  no 
  denticle.
