  Total 
  

  

  The 
  great 
  differences 
  in 
  depth 
  through 
  which 
  some 
  of 
  the 
  species, 
  

   unquestionably 
  inhabiting 
  the 
  region 
  of 
  the 
  bottom, 
  are 
  recorded 
  as 
  

   ranging 
  is 
  worthy 
  of 
  notice. 
  Of 
  the 
  18 
  inhabitants 
  of 
  the 
  neighborhood 
  

   of 
  the 
  bottom 
  which 
  are 
  recorded 
  as 
  taken 
  below 
  1,000 
  fathoms, 
  9 
  have 
  

   ;i 
  recorded 
  range 
  of 
  over 
  800 
  fathoms, 
  and 
  one 
  of 
  them, 
  Parapagurus 
  

   pilosimanus, 
  of 
  nearly 
  2,000 
  fathoms. 
  The 
  case 
  of 
  the 
  Parapagurus 
  is 
  

   very 
  remarkable. 
  It 
  was 
  taken 
  at 
  fifteen 
  stations 
  and 
  in 
  250 
  to 
  640 
  

   fathoms 
  by 
  the 
  Fish 
  Hawk 
  and 
  Blake 
  in 
  1880-'81-'82, 
  and 
  in 
  great 
  

   abundance 
  at 
  one 
  station 
  in 
  319 
  fathoms, 
  where 
  nearly 
  four 
  hundred 
  

   large 
  specimens 
  were 
  taken 
  at 
  once. 
  All 
  these 
  earlier 
  specimens 
  were 
  

   inhabiting 
  carcinoscia 
  of 
  Epkoanthns 
  paguriphilus. 
  In 
  the 
  Albatross 
  

   dredgings 
  of 
  1883-'S4-'85, 
  it 
  was 
  taken 
  at 
  twenty-one 
  stations, 
  ranging 
  

   in 
  depth 
  from 
  353 
  to 
  2,221 
  fathoms; 
  but 
  at 
  fourteen 
  of 
  these 
  stations, 
  

   all 
  of 
  which 
  were 
  below 
  ] 
  ,500 
  fathoms, 
  none 
  of 
  the 
  specimens 
  were 
  asso- 
  

   ciated 
  with 
  the 
  same 
  species 
  of 
  JEJpisoanthus, 
  some 
  of 
  them 
  being 
  in 
  Dpi- 
  

   zoantliU8 
  abyssorum, 
  others 
  in 
  naked 
  gastropod 
  shells, 
  and 
  still 
  others 
  

   in 
  an 
  actiniau 
  polyp, 
  apparently 
  the 
  Urticina 
  consors 
  Verrill, 
  which 
  often 
  

   serves 
  for 
  thecarcincecium 
  of 
  Sympaguruspietus, 
  from 
  164 
  to 
  264 
  fathoms. 
  

  

  The 
  color 
  of 
  the 
  abyssal 
  Crustacea 
  is 
  very 
  characteristic. 
  A 
  few 
  

   species 
  are 
  apparently 
  nearly 
  colorless, 
  but 
  the 
  great 
  majority 
  are 
  some
