  Zoarium

  Eschar 
  w-form, 
  branches 
  2-3 
  millim. 
  wide. 
  Zooecia 
  

   usually 
  flat, 
  separated 
  by 
  a 
  wide 
  slightly 
  raised 
  margin, 
  oblong, 
  

   arched 
  above, 
  sides 
  parallel, 
  four 
  more 
  or 
  less 
  regular 
  rows 
  of 
  

   parallel 
  pores, 
  between 
  which 
  are 
  rounded 
  granulations 
  ; 
  oral 
  

   aperture 
  horseshoe-shaped, 
  rather 
  contracted 
  below, 
  proximal 
  edge 
  

   straight, 
  with 
  a 
  large 
  rounded 
  or 
  angular 
  denticle 
  turned 
  inwards, 
  

   also 
  a 
  denticle 
  on 
  each 
  side 
  of 
  the 
  aperture. 
  Oral 
  aperture 
  0*14 
  

   millim.

  It 
  is 
  difficult 
  to 
  know 
  where 
  this 
  should 
  be 
  generically 
  placed 
  ; 
  

   but 
  as 
  the 
  peristomial 
  characters 
  in 
  Smittia 
  are 
  very 
  variable, 
  we 
  

   seem 
  to 
  be 
  justified 
  in 
  placing 
  it 
  with 
  Smittia, 
  on 
  account 
  of 
  the 
  form 
  

   of 
  the 
  denticles.

  Zoarium 
  orbicular, 
  somewhat 
  convex, 
  with 
  the 
  zooecia 
  radiating 
  

   from 
  the 
  centre. 
  Zooecia 
  distinct, 
  ovate, 
  raised, 
  with 
  a 
  prominent 
  

   mucro 
  or 
  avicularium 
  immediately 
  below 
  the 
  oral 
  aperture, 
  and 
  two 
  

   much- 
  raised 
  tubular 
  avicularia 
  above 
  the 
  aperture. 
  The 
  area 
  of 
  the 
  

   mucro 
  is 
  without 
  pores 
  ; 
  but 
  below 
  this 
  there 
  is 
  an 
  irregular 
  double 
  

   row 
  of 
  large 
  pores 
  ; 
  oral 
  aperture 
  rounded 
  above, 
  with 
  a 
  prominent 
  

   expanded 
  denticle 
  in 
  the 
  aperture, 
  giving 
  the 
  appearance 
  of 
  two 
  

   distinct 
  sinuses. 
  Oral 
  aperture 
  0-12 
  millim. 
  wide. 
  Distal 
  rosette- 
  

   plate 
  near 
  the 
  base 
  of 
  the 
  distal 
  wall, 
  very 
  elongate. 
  I 
  am 
  unable 
  

   to 
  see 
  the 
  shape 
  of 
  the 
  true 
  oral 
  aperture, 
  but 
  think 
  that 
  the 
  denticle 
  

   (although 
  placed 
  higher 
  than 
  is 
  usual 
  in 
  Smittia) 
  indicates 
  the 
  

   generic 
  affinity.
