  This 
  well-known 
  species 
  is 
  widely 
  distributed 
  throughout 
  the 
  colder 
  

   waters 
  of 
  the 
  world, 
  north 
  and 
  south. 
  There 
  is 
  no 
  significant 
  differ- 
  

   ence 
  between 
  these 
  Japanese 
  specimens 
  and 
  those 
  taken 
  from 
  New 
  

   England 
  waters 
  on 
  the 
  early 
  cruises 
  of 
  the 
  Alhatross, 
  with 
  which 
  they 
  

   have 
  been 
  compared. 
  These 
  are 
  the 
  first 
  records 
  of 
  this 
  species 
  in 
  

   Japanese 
  waters, 
  although 
  Hilton 
  identifies 
  several 
  specimens 
  from 
  

   the 
  eastern 
  North 
  Pacific. 
  The 
  stations 
  at 
  which 
  this 
  species 
  was 
  

   collected 
  range 
  from 
  latitude 
  33°23' 
  N. 
  to 
  42°10'

  all 
  off 
  the 
  eastern 
  

   shores 
  of 
  the 
  archipelago.

  One 
  small 
  recently 
  moulted 
  specimen 
  of 
  this 
  species 
  is 
  represented 
  

   in 
  the 
  collection. 
  The 
  proboscis 
  measures 
  1.75 
  mm., 
  and 
  the 
  specimen 
  

   is 
  about 
  half 
  the 
  size 
  of 
  an 
  average 
  full-grown 
  example 
  from 
  the 
  

   North 
  Atlantic. 
  It 
  appears 
  to 
  be 
  a 
  male. 
  Like 
  C. 
  colossea, 
  this 
  is 
  evi- 
  

   dently 
  a 
  cosmopolitan 
  deep-water 
  species. 
  This 
  locality 
  is 
  southeast 
  

   of 
  Honshu.

  This 
  is 
  the 
  second 
  record 
  for 
  this 
  species, 
  which 
  was 
  first 
  collected 
  

   by 
  the 
  Challenger 
  at 
  station 
  237, 
  latitude 
  34°37' 
  N, 
  longitude 
  140°32' 
  

   E, 
  1,875 
  fathoms. 
  In 
  appearance 
  it 
  is 
  superficially 
  like 
  C. 
  angusta, 
  

   but 
  it 
  is 
  readily 
  separable 
  from 
  that 
  species 
  by 
  the 
  short 
  second 
  joint 
  

   of 
  the 
  palpus 
  and 
  by 
  the 
  combination 
  of 
  long 
  tarsus 
  and 
  short 
  terminal 
  

   claw. 
  The 
  proboscis 
  in 
  these 
  specimens 
  is 
  somewhat 
  longer 
  than 
  the
