  ber 
  of 
  spines 
  on 
  the 
  base 
  of 
  the 
  propodus 
  is 
  apparently 
  variable; 
  in 
  

   some 
  specimens 
  there 
  are 
  four. 
  The 
  color 
  varied, 
  in 
  alcohol, 
  from 
  light 
  

   straw 
  to 
  a 
  bright 
  reddish 
  brown. 
  The 
  distribution, 
  according 
  to 
  these 
  

   collections, 
  is 
  from 
  north 
  of 
  Hokkaido 
  to 
  west 
  of 
  Kyushu, 
  and 
  south 
  of 
  

   Honshu. 
  The 
  southern 
  stations 
  are 
  in 
  deeper 
  water. 
  

  

  This 
  species 
  closely 
  resembles 
  Phoxichilidiurri 
  micropal'pid'wm 
  Hil- 
  

   ton 
  (1942f, 
  p. 
  72), 
  described 
  from 
  Albatross 
  station 
  4792, 
  latitude 
  

   54°36'15" 
  N., 
  longitude 
  166°57'15'' 
  E., 
  72 
  fathoms. 
  It 
  differs 
  from 
  

   this 
  species 
  in 
  having 
  a 
  longer 
  femur 
  with 
  15 
  instead 
  of 
  5 
  femoral 
  

   pores, 
  in 
  having 
  a 
  longer 
  third 
  joint 
  of 
  the 
  oviger, 
  and 
  in 
  having 
  

   auxiliary 
  claws 
  less 
  than 
  a 
  third 
  as 
  long 
  as 
  the 
  terminal 
  claw, 
  whereas 
  

   those 
  of 
  Hilton's 
  species 
  are 
  half 
  as 
  long.

  Description. 
  — 
  Trunk 
  oval 
  in 
  outline, 
  completely 
  segmented, 
  lateral 
  

   processes

  than 
  their 
  own 
  diameter. 
  There 
  

   are 
  no 
  tubercles, 
  processes, 
  or

  base 
  and 
  tip. 
  

  

  Proboscis 
  blunt 
  at 
  tip,

   the 
  middle
