  tuberauces 
  projecting 
  from 
  the 
  upper 
  postero-lateral 
  angles 
  

   of 
  the 
  shell 
  in 
  that 
  species 
  of 
  vSarsiella. 
  I 
  looked 
  in 
  vain 
  

   for 
  males. 
  It 
  is 
  interesting 
  that 
  while 
  several 
  infested 
  

   specimens 
  of 
  S. 
  hispid 
  a 
  were 
  discovered, 
  I 
  did 
  not 
  find 
  the 
  

   parasite 
  on 
  any 
  specimen 
  of 
  S. 
  Hanseni, 
  which 
  was 
  taken 
  

   together 
  with 
  the 
  other 
  form, 
  but 
  was 
  much 
  more 
  abundant, 
  

   and 
  I 
  have 
  inspected 
  a 
  good 
  number 
  of 
  the 
  latter 
  species. 
  

   Prof. 
  G. 
  S. 
  Brady 
  established 
  both 
  species 
  of 
  Ostracoda 
  on 
  

   material 
  from 
  the 
  Copenhagen 
  Museum. 
  

  

  Remarks. 
  — 
  The 
  rich 
  material 
  of 
  both 
  species 
  of 
  Sar- 
  

   siella 
  Avas 
  procured 
  to 
  our 
  Museum 
  in 
  the 
  following 
  way. 
  

   I 
  wrote 
  an 
  instruction 
  to 
  H. 
  Suter, 
  Esq., 
  how 
  he 
  should 
  deal 
  

   with 
  the 
  bottom 
  material 
  and 
  send 
  it 
  to 
  us 
  preserved 
  in 
  

   spirit 
  ; 
  in 
  sieved 
  mud 
  received 
  from 
  him 
  I 
  found 
  a 
  good 
  

   number 
  of 
  tolerably 
  preserved 
  specimens 
  of 
  these 
  Ostracoda 
  

   and 
  of 
  numerous 
  other 
  Crustacea, 
  many 
  of 
  which 
  were 
  new 
  

   to 
  science. 
  The 
  above-described 
  parasite 
  must 
  be 
  rather 
  

   easy 
  to 
  secure 
  by 
  zoologists 
  living 
  in 
  New 
  Zealand 
  or 
  staying- 
  

   there 
  during 
  some 
  time. 
  I 
  will 
  exhort 
  these 
  colleagues 
  to 
  

   take 
  up 
  the 
  investigation 
  and 
  look 
  for 
  males 
  and 
  stages 
  of 
  

   development. 
  I 
  suppose 
  that 
  if 
  my 
  own 
  material 
  had 
  been 
  

   somewhat 
  better 
  preserved 
  or 
  still 
  richer 
  I 
  should 
  have 
  been 
  

   able 
  to 
  find 
  these 
  tiny 
  animals, 
  which 
  probably 
  were 
  fallen 
  

   out 
  before 
  my 
  inspection. 
  My 
  earlier 
  monogiaph 
  of 
  the 
  

   family 
  gives 
  full 
  information 
  on 
  the 
  mode 
  of 
  proceeding 
  

   applied 
  by 
  me 
  in 
  ordev 
  to 
  find 
  and 
  deal 
  with 
  such 
  minute 
  

   forms 
  without 
  damaging 
  them. 
  1 
  am 
  inclined 
  to 
  believe 
  that 
  

   several 
  species 
  of 
  Ostracoda 
  inhabiting 
  other 
  places 
  in 
  the 
  

   world 
  are 
  infested 
  with 
  hitherto 
  unknown 
  species 
  of 
  Sphaero- 
  

   nelloides. 
  Our 
  knowledge 
  of 
  parasitic 
  Copepoda 
  is 
  still 
  in 
  

   its 
  infancy, 
  and 
  numerous 
  interesting, 
  even 
  startling, 
  dis- 
  

   coveries 
  in 
  this 
  field 
  are 
  to 
  be 
  done 
  by 
  zoologists 
  in 
  the 
  

   future.
