  the

   may 
  be 
  expected 
  to 
  turn 
  up

  it

  Eight

  known 
  from

  the

  StauropTiora

   Aurelia

  on 
  the

  hand, 
  the 
  

   eudoxid 
  of 
  Nectopyramis 
  diomedae, 
  a 
  species 
  previously 
  recorded 
  only 
  

   from 
  the 
  tropical 
  Pacific, 
  was 
  likewise 
  taken 
  off 
  the 
  Kurile 
  Islands, 
  

   but 
  it 
  is 
  known 
  from 
  so 
  few 
  captures 
  that 
  it 
  can 
  not 
  be 
  assigned 
  to 
  

   any 
  definite 
  temperature 
  zone. 
  Catahlema

  In 
  examining 
  the 
  records 
  of 
  the 
  Albatross 
  from 
  the 
  Sea 
  of 
  Japan 
  

   we 
  are 
  confronted 
  by 
  the 
  rather 
  surprising 
  fact 
  that 
  although 
  the 
  

   intermediate 
  5-foot 
  net 
  and 
  the 
  small 
  plankton 
  nets 
  were 
  used 
  at 
  

   15 
  of 
  the 
  86 
  trawling 
  stations 
  occupied, 
  medusae 
  were 
  taken 
  in 
  only 
  

   3 
  hauls. 
  Only 
  four 
  species 
  of 
  medusae 
  were 
  taken; 
  i. 
  e., 
  Liriope 
  

   tetraphyUa, 
  Aglaura 
  hemistoma, 
  Aglantha 
  digitale, 
  Dactylometra 
  paci- 
  

   fica, 
  and 
  three 
  siphonophores. 
  Rosacea 
  plicata, 
  DipJiyes 
  arctica, 
  and 
  

   D. 
  truncata; 
  while 
  the 
  only 
  previous 
  records 
  which 
  I 
  have 
  been 
  able 
  

   to 
  find 
  are 
  that 
  of 
  Aeginopsis 
  laurentii, 
  by 
  Haeckel 
  (1879) 
  and 
  

   Parumbrosa 
  polylohata 
  by 
  Kishinouye 
  (1910). 
  

  

  The 
  apparent 
  absence 
  of 
  the 
  smaller 
  surface 
  medusae 
  might 
  

   perhaps 
  be 
  credited 
  to 
  their 
  being 
  overlooked 
  in 
  the 
  mixed 
  plankton; 
  

   but 
  we 
  can 
  not 
  account 
  in 
  this 
  way 
  for 
  the 
  failure 
  to 
  find 
  any 
  of 
  the 
  

   larger 
  red 
  "intermediate" 
  genera, 
  as 
  for 
  example, 
  AtoUa, 
  PeripliyUa, 
  

   Aeginura, 
  because 
  they 
  are 
  made 
  exceedingly 
  conspicuous 
  by 
  their 
  

   color. 
  And 
  as 
  none 
  of 
  them 
  were 
  taken, 
  it 
  is 
  fair 
  to 
  assume 
  that 
  the 
  

   scarcity 
  of 
  the 
  medusae 
  on 
  the 
  Sea 
  of 
  Japan 
  is 
  a 
  real, 
  not 
  an 
  apparent 
  

   phenomenon. 
  

  

  The 
  short 
  Ust 
  includes 
  three 
  warm 
  water 
  members, 
  Aglaura, 
  

   Liriope, 
  Dactylometra, 
  and 
  two 
  cold 
  water 
  ones, 
  Aglantlm 
  and 
  Diphyes 
  

   arctica, 
  with 
  two, 
  Rosacea 
  plicata 
  and 
  Diphyes 
  truncata, 
  which 
  are 
  

   probably 
  cosmopohtan 
  ; 
  and 
  data 
  of 
  the 
  specimens 
  shows 
  that 
  Aglaura 
  

   and 
  Liriope 
  were 
  taken 
  on 
  the 
  surface, 
  while 
  Aglantha 
  and 
  Diphyes 
  

   were 
  encountered 
  only 
  in 
  intermediate 
  hauls, 
  the 
  difference 
  in 
  bathy- 
  

   metric 
  range 
  being 
  well 
  illustrated 
  by 
  the 
  coincidence 
  that 
  Aglaura
