  THE 
  

  

  ing 
  to 
  Tine, 
  the 
  apertures 
  of 
  one 
  row 
  of 
  annnlations 
  are 
  on 
  a 
  line 
  

   with 
  the 
  cell-walls 
  of 
  the 
  succeeding 
  row. 
  

  

  The 
  same 
  difference 
  may 
  be 
  noted 
  between 
  the 
  several 
  species 
  of 
  

   Entalophora 
  and 
  Spiropora 
  from 
  Banville, 
  which 
  Haime 
  figures. 
  

   The 
  zocecia 
  are 
  ordinarily 
  disposed 
  in 
  alternating 
  rows, 
  whereas 
  

   in 
  the 
  Dorset 
  forms 
  the 
  cell-walls 
  are 
  thicker 
  and 
  the 
  cell 
  arrange- 
  

   ment 
  in 
  longitudinal 
  lines.

  Zoarium 
  erect, 
  ramose 
  and 
  robust, 
  the 
  stem 
  nearly 
  2 
  millim. 
  

   thick, 
  dichotomously 
  branched. 
  Zocecia 
  large, 
  the 
  peristomes 
  ar- 
  

   ranged 
  at 
  a 
  spiral 
  angle 
  of 
  from 
  40° 
  to 
  50°. 
  Zocecia 
  free 
  for 
  about 
  

   one 
  fourth 
  of 
  their 
  length; 
  the 
  exsert 
  part, 
  where 
  perfect, 
  diminish- 
  

   ing 
  in 
  size 
  towards 
  the 
  aperture, 
  where 
  it 
  becomes 
  more 
  conical, 
  and 
  

   frequently 
  projecting 
  horizontally 
  from 
  the 
  stem. 
  Apertures 
  orbi- 
  

   cular, 
  ten 
  to 
  each 
  annulation, 
  closures 
  within 
  the 
  orifice. 
  Surface 
  

   of 
  zoarium 
  punctate 
  and 
  wrinkled. 
  Surface-pores 
  slightly 
  exsert. 
  

   Ovicells 
  funnel-shaped 
  inflations 
  enveloping 
  one 
  or 
  more 
  cells 
  

   (PL

  A 
  longitudinal 
  section 
  shows 
  large 
  communication-pores 
  in 
  the 
  

   cell-walls 
  of 
  the 
  interior 
  of 
  the 
  zoarium 
  ; 
  and 
  I 
  think 
  there 
  is 
  evi- 
  

   dence 
  of 
  club-like 
  rays 
  on 
  the 
  surface 
  of 
  the 
  inner 
  wall 
  as 
  described 
  

   by 
  Waters 
  in 
  some 
  Australian 
  Entalophorce 
  *. 
  Between 
  the 
  surface- 
  

   pores 
  also 
  there 
  are 
  traces 
  of 
  fine 
  granulation. 
  The 
  zocecial 
  tubes 
  

   in 
  section 
  are 
  seen 
  to 
  contain 
  coloured 
  grains 
  probably 
  of 
  oxide 
  of 
  

   iron. 
  

  

  As 
  I 
  have 
  before 
  noted, 
  this 
  may 
  be 
  the 
  erect 
  stage 
  of 
  Proboscina 
  

   spatiosa, 
  but 
  from 
  other 
  Entalophora 
  it 
  is 
  marked 
  off 
  by 
  the 
  greater 
  

   thickness 
  of 
  the 
  zoarium, 
  and 
  by 
  the 
  large 
  zocecia 
  and 
  apertures. 
  

   It 
  has, 
  however, 
  some 
  relationship 
  to 
  Entalophora 
  raripora, 
  d'Orb.
