  parative 
  Zoology 
  collected 
  by 
  Professor 
  Kincaid, 
  give 
  a 
  fair 
  idea, 
  

   though 
  certainly 
  far 
  from 
  a 
  complete 
  survey, 
  of 
  its 
  medusa 
  fauna. 
  

   The 
  combin,ed 
  list 
  from 
  Puget 
  Sound, 
  coast 
  of 
  Washington, 
  and 
  

   southern 
  British 
  Columbia, 
  is 
  as 
  follows: 
  

  

  Sarsia 
  rosaria. 
  Halistaura 
  cellularia. 
  

  

  Sarsia 
  eximia. 
  Phialidium 
  gregarium. 
  

  

  Stomotoca 
  atra. 
  Aequorea 
  aequorea. 
  

  

  Neoturris 
  brevicornis. 
  Gonionemus 
  vertens. 
  

  

  Catablcma 
  vmlticirrata. 
  Aglantha 
  digitate. 
  

  

  Bougainvillea 
  bougainvillei. 
  Cyanea 
  arctica 
  (colorless 
  var.). 
  

  

  Proboscydactyla 
  flavicirrhata, 
  Dactylometra 
  species? 
  

  

  Polyorchis 
  penidllatum. 
  Chrysaora 
  helvola. 
  

  

  Polyorchis 
  minuta. 
  Phacellophora 
  species? 
  

  

  Melicertum 
  georgicum. 
  Aurelia 
  aurita. 
  

   Staurophora 
  mertensii. 
  

  

  Likewise 
  the 
  siphonophores, 
  Diphyes 
  appendiculata, 
  PJiysalia, 
  Porpita, 
  

   and 
  Velella; 
  and 
  the 
  present 
  collection 
  contains 
  specimens 
  of 
  Hetero- 
  

   tiara 
  anonyma 
  and 
  Crossota 
  pedunculata 
  taken 
  in 
  intermediate 
  hauls 
  

   off 
  British 
  Columbia. 
  

  

  The 
  general 
  character 
  of 
  this 
  list 
  differs 
  from 
  that 
  of 
  Bering 
  Sea 
  by 
  

   the 
  appearance 
  of 
  the 
  very 
  noticeable 
  genera 
  Polyorchis, 
  Halistaura, 
  

   Dactylometra, 
  and 
  by 
  the 
  tropical 
  siphonophores 
  Physalia, 
  Porpita, 
  

   and 
  Velella, 
  whUe 
  the 
  dark-colored 
  Cyanea 
  of 
  the 
  north 
  is 
  replaced 
  by 
  

   a 
  colorless 
  variety, 
  of 
  which 
  I 
  have 
  seen 
  examples. 
  At 
  the 
  same 
  

   time 
  seven 
  of 
  the 
  Bering 
  Sea 
  species 
  are 
  also 
  known 
  from 
  the 
  Puget 
  

   Sound 
  region, 
  while 
  it 
  would 
  not 
  be 
  surprising 
  to 
  find 
  Sarsia 
  rosaria 
  

   C^tuhulosa), 
  Melicertum, 
  and 
  Phialidium 
  in 
  Bering 
  Sea, 
  judging 
  from 
  

   the 
  occurrence 
  of 
  these 
  genera 
  in 
  the 
  north 
  Atlantic. 
  

  

  As 
  we 
  pass 
  southward 
  from 
  the 
  Puget 
  Sound 
  region, 
  we 
  find 
  only 
  

   a 
  few 
  scattered 
  records 
  of 
  medusae 
  until 
  we 
  reach 
  San 
  Diego. 
  And 
  

   somewhere 
  in 
  tliis 
  long 
  stretch 
  the 
  cold-water 
  species 
  which 
  compose 
  

   the 
  great 
  bulk 
  of 
  the 
  medusa 
  fauna 
  of 
  Bering 
  Sea 
  entirely 
  disappear, 
  

   the 
  most 
  southerly 
  record 
  for 
  any 
  of 
  them 
  on 
  the 
  surface 
  being 
  

   Fewkes's 
  (1889) 
  capture 
  of 
  Hyhocodon 
  prolifer 
  at 
  Santa 
  Barbara, 
  

   though 
  the 
  northern 
  Aglantha 
  digitale 
  is 
  represented 
  by 
  a 
  distmct 
  

   variety 
  in 
  the 
  mtermediatc 
  depths 
  of 
  the 
  tropical 
  Pacific 
  (1909a). 
  

   The 
  oidy 
  Leptomedusa 
  known 
  to 
  be 
  common 
  to 
  San 
  Diego 
  and 
  to 
  

   Bering 
  Sea 
  is 
  the 
  cosmopolitan 
  Aequorea 
  aequorea, 
  and 
  even 
  in 
  this 
  

   case 
  it 
  is 
  doubtful 
  whether 
  it 
  is 
  represented 
  by 
  the 
  same 
  variety. 
  

  

  On 
  the 
  western 
  side 
  of 
  the 
  Pacific 
  the 
  available 
  data 
  is 
  more 
  exten- 
  

   sive, 
  thanks 
  to 
  the 
  collections 
  from 
  Japan 
  recorded 
  b}^ 
  Maas 
  (1909) 
  

   and 
  by 
  Kishmouye 
  (1902, 
  1910), 
  and 
  to 
  the 
  Fisheries 
  steamer 
  

   Albatross 
  series 
  from 
  the 
  southern 
  part 
  of 
  the 
  Sea 
  of 
  Okhotsk, 
  a 
  virgin 
  

   field, 
  and 
  the 
  Eastern 
  Sea 
  south 
  of 
  Japan. 
  The 
  species 
  taken 
  m 
  the 
  

   Sea 
  of 
  Okhotsk 
  are 
  Sarsia 
  japonica,
