  was 
  taken 
  on 
  the 
  surface 
  close 
  by 
  the 
  spot 
  where 
  the 
  two 
  cold 
  water 
  

   species 
  were 
  brought 
  up 
  from 
  the 
  deeper 
  waters, 
  the 
  surface 
  tempera- 
  

   tures 
  bemg 
  77°-80°, 
  that 
  at 
  245 
  fathoms

  Haeckel's 
  record 
  of 
  

   Aeginopsis 
  unfortunately 
  gives 
  neither 
  the 
  date, 
  whether 
  winter 
  or 
  

   summer, 
  nor 
  the 
  exact 
  locaUty. 
  And 
  both 
  of 
  these 
  are 
  of 
  im- 
  

   portance, 
  because 
  in 
  summer 
  the 
  surface 
  temperatures 
  of 
  the 
  Sea 
  

   of 
  Japan 
  range 
  from 
  about 
  60° 
  (northern 
  end) 
  to 
  about 
  80° 
  (Korea 
  

   Channel); 
  while 
  in 
  winter 
  the 
  surface 
  waters 
  of 
  its 
  northern 
  half, 
  

   between 
  Hoklcaido 
  and 
  the 
  Siberian 
  coast, 
  are 
  cooled 
  to 
  45° 
  or 
  less. 
  

   In 
  the 
  portion 
  of 
  the 
  Eastern 
  Sea 
  south 
  of 
  the 
  Straits 
  of 
  Korea 
  

   traversed 
  by 
  the 
  Albatross, 
  the 
  hauls 
  brought 
  to 
  light 
  an 
  abundant 
  

   harvest 
  of 
  medusae, 
  the 
  species 
  taken 
  near 
  the 
  Goto 
  Islands, 
  off 
  

   Kagoshima 
  Gulf, 
  and 
  off 
  Kyushiu 
  Island

  The 
  list 
  is 
  essentially 
  tropical, 
  as 
  might 
  have 
  been 
  expected 
  from 
  

   the 
  surface 
  temperatures 
  (83°-85°) 
  at 
  the 
  season 
  the 
  collection 
  was 
  

   gathered, 
  all 
  the 
  surface 
  medusae 
  being 
  known 
  from 
  the 
  tropical 
  

   parts 
  of 
  the 
  Pacific 
  or 
  Indian 
  Oceans, 
  except 
  Turritopsis 
  nutriculata, 
  

   Olindioides, 
  and 
  Parumhrosa 
  polyhata, 
  the 
  last 
  two 
  known 
  only 
  from 
  

   Japan. 
  All 
  the 
  siphonophores, 
  except 
  Vogtia 
  pentacantha, 
  are 
  known 
  

   from 
  the 
  tropical 
  Pacific, 
  or 
  from 
  the 
  Malaysian 
  region, 
  while 
  most 
  of 
  

   them 
  are 
  characteristic 
  of 
  the 
  warmer 
  regions 
  of 
  all 
  three 
  great 
  

   oceans. 
  

  

  During 
  the 
  summer 
  months, 
  when 
  the 
  southeastern 
  coasts 
  of 
  

   Japan 
  are 
  bathed 
  by 
  the 
  warm 
  Kuro 
  Shiro 
  current, 
  the 
  tropical 
  

   holoplanktonic 
  coelenterate 
  fauna 
  extends 
  northward 
  along 
  the 
  

   coast 
  of 
  Nipon, 
  at 
  least 
  as 
  far 
  as 
  Suruga 
  and 
  Sagami 
  Bays, 
  where
