  \_Reacl 
  before 
  the 
  Otago 
  Institute, 
  8th 
  October, 
  1878.] 
  

  

  Last 
  month, 
  while 
  investigating 
  the 
  structure 
  of 
  Patella 
  argentea, 
  Quoy 
  and 
  

  

  Gaimard, 
  I 
  discovered 
  numerous 
  specimens 
  of 
  an 
  infusorian 
  attached 
  to 
  the 
  

  

  branchias, 
  of 
  which 
  the 
  following 
  is 
  a 
  description 
  : 
  — 
  

  

  Body 
  campanulate, 
  naked, 
  devoid 
  of 
  cilia, 
  hyaline, 
  highly 
  contractile 
  ; 
  

   sessile 
  or 
  subsessile 
  ; 
  mouth 
  surrounded 
  by 
  a 
  spiral 
  ring 
  of 
  rather 
  coarse 
  

   cilia, 
  which 
  are 
  capable 
  of 
  being 
  moved 
  or 
  held 
  motionless 
  at 
  the 
  will 
  of 
  the 
  

   animal. 
  Length, 
  -g-J-^ 
  inch. 
  These 
  little 
  animals 
  were 
  attached 
  to 
  all 
  parts 
  

   of 
  the 
  branchise, 
  and 
  closed 
  up 
  suddenly, 
  in 
  the 
  manner 
  of 
  Vorticella, 
  when 
  

   touched 
  by 
  any 
  foreign 
  body. 
  

  

  The 
  absence 
  of 
  a 
  carapace 
  and 
  of 
  a 
  stalk 
  would 
  appear 
  to 
  put 
  thi3 
  

   Species 
  into 
  Triclioda, 
  Ehr., 
  but 
  the 
  disposition 
  of 
  the 
  cilia 
  round 
  the 
  mouth 
  

   precludes 
  this 
  ; 
  and 
  I 
  am 
  inclined 
  to 
  regard 
  it 
  as 
  a 
  Cothurnia, 
  in 
  which 
  the 
  

   lorica 
  has 
  become 
  obsolete 
  owing 
  to 
  its 
  commensual 
  habits. 
  I 
  therefore 
  

   propose 
  to 
  call 
  it 
  Cothurnia 
  patellce.
