  is 
  called 
  for, 
  Gazelletta 
  may 
  be 
  divided 
  into 
  the 
  body 
  

   (? 
  = 
  central 
  capsnle) 
  and 
  head 
  (=" 
  shell-mouth" 
  and 
  arms), 
  

   the 
  intra-capsular 
  protoplasm 
  and 
  nucleus 
  lying 
  in 
  the 
  body, 
  

   the 
  extra-capsular 
  protoplasm 
  and 
  phEeodium 
  in 
  the 
  head. 
  

   The 
  body 
  is 
  nearly 
  spherical 
  or 
  ovoid. 
  The 
  body-wall 
  stains 
  

   deeply 
  in 
  hasmatoxylin, 
  is 
  soft 
  and 
  elastic, 
  and 
  shrivels 
  very 
  

   greatly 
  in 
  preparation 
  for 
  sections. 
  It 
  seems 
  to 
  me 
  to 
  bo 
  

   homologous 
  with 
  the 
  central 
  capsule 
  rather 
  than 
  with 
  the 
  

   shell 
  of 
  Planktonetta, 
  because 
  it 
  is 
  the 
  only 
  recognisable 
  

   membrane 
  in 
  the 
  position 
  of 
  a 
  central 
  capsule, 
  and 
  it 
  shows 
  

   no 
  sign 
  of 
  being 
  continuous 
  with 
  the 
  shell-mouth, 
  which 
  is 
  

  

  Abor.al

  — 
  Specimen 
  with 
  thick 
  body-wall, 
  and 
  with 
  leii 
  arms, 
  most 
  of 
  

   which 
  liave 
  been 
  broken 
  ; 
  all 
  except 
  llie 
  most 
  anterior 
  pair 
  

   should 
  lie 
  more 
  or 
  less 
  by 
  the 
  side 
  of 
  the 
  body. 
  Drawn 
  from 
  

   the 
  "posterior" 
  side; 
  the 
  terminal 
  spines 
  of 
  the 
  arms 
  alone 
  

   have

  Body 
  (central 
  capsule?); 
  m. 
  its 
  internal 
  

   lining 
  membrane;

  alleged

  of 
  the 
  shell-mouth 
  ;

  row 
  

   of 
  pores. 
  

  

  undoubtedly 
  skeletal. 
  It 
  is 
  continued 
  as 
  a 
  very 
  thin 
  

   membrane 
  over 
  the 
  " 
  oral 
  ^' 
  surface 
  of 
  the 
  intra-capsular 
  

   protoplasm, 
  where 
  it 
  is 
  perforated 
  by 
  the 
  suspensory 
  pro- 
  

   cesses 
  and 
  by 
  the 
  bundle 
  of 
  communicating 
  tubes, 
  as 
  in 
  

   Planktonetta. 
  These 
  processes 
  and 
  tubes 
  are 
  the 
  only 
  

   apparent 
  means 
  by 
  which 
  the 
  body 
  is 
  attached 
  to 
  the 
  

   remainder 
  of 
  the 
  organism, 
  but 
  I 
  dare 
  not 
  state 
  positively
