  inspired 
  specific 
  names. 
  The 
  terminal 
  claw 
  is 
  of 
  variable 
  length, 
  

   in 
  some 
  specimens 
  (in 
  the 
  lot 
  from 
  station 
  4826) 
  being 
  half 
  as 
  long 
  

   as 
  the 
  propodus. 
  The 
  figure 
  in 
  Ohshima 
  and 
  Kishida's 
  catalog 
  sug- 
  

   gests 
  the 
  species 
  described 
  below 
  as 
  Nymphon 
  micropedes, 
  although 
  

   it 
  is 
  too 
  small 
  for 
  detailed 
  comparison. 
  Their 
  figure 
  indicates 
  a 
  species 
  

   with 
  a 
  short 
  tarsus, 
  whereas 
  the 
  one 
  clear 
  detail 
  of 
  Ortmann's 
  figure 
  

   is 
  the 
  subequal 
  condition 
  of 
  the 
  tarsus 
  and 
  propodus, 
  and 
  it 
  also 
  indi- 
  

   cates 
  a 
  much 
  longer 
  second 
  coxa 
  than 
  represented 
  in 
  Ortmann's 
  figure 
  

   and 
  my 
  material. 
  

  

  This 
  species 
  is 
  generally 
  a 
  southern 
  form, 
  but 
  it 
  evidently 
  occurs 
  

   occasionally 
  as 
  far 
  north 
  as 
  about 
  40° 
  (station 
  4809) 
  and 
  is 
  found 
  

   on 
  both 
  sides 
  of 
  Honshu.

  specimens). 
  

  

  This 
  is 
  apparently 
  one 
  of 
  the 
  characteristic 
  species 
  of 
  the 
  Sea 
  of 
  

   Okhotsk, 
  but 
  the 
  two 
  large 
  collections 
  (stations 
  5037 
  and 
  5038) 
  were 
  

   made 
  off 
  the 
  southern 
  shore 
  of 
  Hokkaido. 
  Its 
  bathymetric 
  range 
  is 
  

   from 
  52 
  to 
  175, 
  or 
  perhaps 
  349, 
  fathoms. 
  Several 
  specimens 
  in 
  the 
  

   larger 
  lots 
  are 
  larvigerous. 
  Most 
  of 
  them 
  are 
  a 
  reddish 
  brown 
  color 
  

   in 
  alcohol. 
  This 
  species 
  has 
  not 
  been 
  found 
  south 
  of 
  latitude 
  42° 
  N.

  This 
  species 
  is 
  similar 
  to 
  N. 
  hraschnikoioi 
  in 
  general 
  appearance, 
  

   but 
  it 
  never 
  has 
  the 
  short 
  tarsal 
  segment 
  of 
  that 
  species, 
  and 
  it 
  is 
  

   usually 
  much 
  larger. 
  It 
  occupies 
  about 
  the 
  same 
  bathymetric 
  and 
  

   geographic 
  range 
  as 
  N. 
  hraschnikowi 
  and 
  it 
  is 
  possible 
  that 
  the 
  two 
  are 
  

   actually 
  varieties 
  of 
  each 
  other, 
  although 
  I 
  could 
  find 
  no 
  transitional 
  

   forms. 
  In 
  N. 
  hodgsoni 
  the 
  shape 
  of 
  the 
  chela 
  is 
  not 
  as 
  variable 
  as 
  in 
  

   N. 
  braschnikowi, 
  where 
  it 
  varies 
  from 
  a 
  graceful 
  curve 
  to 
  the 
  blunt 
  

   grossipes 
  type. 
  Nymphon 
  hodgsoni

  not
