  Phascolion

  the 
  Arctic 
  and 
  North 
  Atlantic 
  Oceans

  The 
  most 
  distinctively 
  abyssal 
  species 
  of 
  Phascolosoma 
  that 
  have 
  

   been 
  found 
  off 
  the 
  eastern 
  coast 
  of 
  America 
  are 
  Phascolosoma 
  fiagriferum 
  

   Selenka, 
  which 
  occurs 
  in 
  1,700-2,620 
  fathoms, 
  and 
  Ph. 
  dnctum, 
  new 
  

   species, 
  found 
  in 
  368-1,290 
  fathoms. 
  Associated 
  with 
  the 
  latter 
  at 
  

   the 
  depth 
  of 
  1,290 
  fathoms 
  was 
  Ph. 
  sahellarise. 
  Ph. 
  eremita 
  (Sars), 
  

   though 
  commonly 
  found 
  in 
  less 
  than 
  100 
  fathoms, 
  has 
  been 
  taken 
  

   in 
  1,098; 
  and 
  Ph. 
  margaritaceum 
  (Sars), 
  the 
  typical 
  form 
  of 
  which 
  

   occurs 
  off 
  the 
  Canadian 
  and 
  Newfoundland 
  coasts 
  in 
  30-75 
  fathoms, 
  

   has 
  a 
  variety 
  which 
  I 
  shall 
  call 
  meridionalis 
  that

   Marthas 
  Vineyard

  fathoms. 
  Phascolosoma 
  procerum 
  Moebius 
  

   has 
  been 
  found 
  in 
  100-266 
  fathoms 
  off 
  our 
  coast, 
  its 
  range 
  apparently 
  

   being 
  somewhat 
  restricted 
  bathymetrically. 
  It 
  is 
  found 
  in 
  the 
  

   North 
  Sea 
  off 
  Edinburgh, 
  Scotland, 
  as 
  well 
  as 
  off 
  the 
  coast 
  of 
  the 
  

   United 
  States 
  near 
  the 
  fortieth 
  parallel. 
  On 
  the 
  other 
  hand. 
  Ph. 
  

   sahellarise 
  and 
  improvisum 
  off 
  this 
  continent 
  have 
  a 
  wide 
  bathymetric 
  

   range, 
  the 
  former 
  occurring 
  from 
  70 
  to 
  1,098 
  fathoms, 
  the 
  latter 
  from 
  

   5 
  to 
  810.
