  The 
  species, 
  whose 
  distribution 
  is 
  discussed 
  in 
  detail, 
  are 
  as 
  

   follows 
  : 
  Corycceus 
  rostratus, 
  Clausocalanus 
  arcuicornis, 
  Acartii 
  

   Clausii, 
  Centropages 
  typicus, 
  Dictyocysta 
  elegans, 
  Undella 
  

   candata, 
  Chcetoceros 
  skeleton, 
  Dactiosolen 
  antarcticus, 
  Challeng- 
  

   eria 
  xiphodon. 
  The 
  author 
  adds 
  : 
  " 
  All 
  the 
  above 
  data, 
  which 
  

   I 
  could 
  easily 
  multiply, 
  prove 
  beyond 
  doubt 
  that 
  the 
  gulf-stream 
  

   water, 
  proceeding 
  from 
  the 
  east 
  of 
  Africa 
  towards 
  the 
  Azores 
  and 
  

   the 
  European 
  coast, 
  expands 
  above 
  the 
  40° 
  N. 
  so 
  far 
  to 
  the 
  west 
  

   as 
  to 
  approach 
  the 
  American 
  coast. 
  From 
  40° 
  N. 
  it 
  advances 
  to 
  

   the 
  north, 
  to 
  Iceland 
  and 
  the 
  Faroe 
  Channel. 
  It 
  turns 
  in 
  Septem- 
  

   ber 
  to 
  the 
  north 
  of 
  Iceland. 
  From 
  the 
  Faroe 
  Channel 
  it 
  flows 
  

   into 
  the 
  North 
  Sea 
  and, 
  as 
  will 
  be 
  shown 
  further 
  on, 
  towards 
  

   Spitzbergen. 
  

  

  In 
  the 
  following 
  I 
  will 
  treat 
  of 
  some 
  styli-plankton 
  forms 
  with 
  

   a 
  very 
  wide 
  range 
  of 
  distribution, 
  in 
  order 
  to 
  show 
  that 
  the 
  

   styli-plankton 
  also 
  follows 
  the 
  South 
  Equatorial 
  current 
  to 
  S. 
  

   America 
  as 
  well 
  as 
  into 
  the 
  Caribbean 
  Sea, 
  and 
  the 
  Antilles 
  and 
  

   Florida 
  currents 
  towards 
  the 
  north."

  Hear 
  are 
  included 
  Par 
  acalanus 
  parvus, 
  Goscinodiscus 
  (Plankto- 
  

   niella) 
  Sol., 
  Rhizosolenia 
  styliformis. 
  The 
  author 
  concludes 
  : 
  

   " 
  The 
  range 
  of 
  distribution 
  of 
  Rhizosolenia 
  styliformis 
  fairly 
  

   indicates 
  the 
  area 
  within 
  which 
  the 
  styli-plankton 
  occurs. 
  

   Although 
  of 
  so 
  wide 
  a 
  range 
  it 
  has 
  been 
  very 
  rarely 
  seen 
  in 
  the 
  

   Sargasso 
  Sea, 
  round 
  which 
  the 
  styli-plankton 
  water 
  occurs. 
  

  

  In 
  March-May 
  the 
  styli-plankton 
  extends 
  along 
  50° 
  N. 
  from 
  

   America 
  to 
  the 
  English 
  Channel. 
  Already 
  in 
  April 
  this 
  area 
  has 
  

   advanced 
  to 
  60° 
  N., 
  in 
  June 
  to 
  Iceland. 
  From 
  that 
  island 
  it 
  

   spreads 
  on 
  the 
  east 
  to 
  the 
  Shetlands, 
  on 
  the 
  west 
  to 
  Greenland, 
  

   where 
  rare 
  specimens 
  follow 
  the 
  east 
  Greenland 
  current 
  and 
  arc 
  

   conveyed 
  in 
  October 
  into 
  Davis 
  Strait. 
  Other 
  specimens 
  follow 
  

   the 
  current 
  to 
  the 
  north 
  of 
  Iceland 
  in 
  September, 
  others 
  drift 
  to 
  

   Spitzbergen, 
  where 
  they 
  already 
  appear 
  in 
  August."
