  This 
  report 
  of 
  the 
  Arctic 
  polychaetes 
  found 
  in 
  the 
  region 
  of 
  Point 
  

   Barrow, 
  Alaska, 
  is 
  based 
  on 
  material 
  collected 
  during 
  1948, 
  1949, 
  and 
  

   1950 
  by 
  G. 
  E. 
  MacGinitie, 
  of 
  the 
  Arctic 
  Research 
  Laboratory. 
  Speci- 
  

   mens 
  were 
  obtained 
  from 
  Eluitkak 
  Pass, 
  Elson 
  Lagoon, 
  near 
  Point 
  

   Barrow, 
  were 
  washed 
  ashore 
  at 
  the 
  Point 
  Barrow 
  base, 
  and 
  were 
  

   dredged 
  within 
  16 
  miles 
  offshore 
  at 
  Point 
  Barrow 
  base 
  in 
  depths 
  of 
  

   1.7 
  to 
  123.5 
  fathoms 
  on 
  bottoms 
  of 
  mud, 
  stones, 
  gravel, 
  rocks, 
  in 
  

   masses 
  of 
  worm 
  tubes, 
  and 
  various 
  combinations 
  of 
  these. 
  Addi- 
  

   tional 
  specimens 
  were 
  collected 
  from 
  fish 
  traps, 
  from 
  screen 
  traps 
  

   lowered 
  through 
  holes 
  made 
  in 
  the 
  ice, 
  and 
  from 
  plankton 
  hauls, 
  

   some 
  of 
  which 
  were 
  made 
  through 
  holes 
  in 
  the 
  ice. 
  The 
  latter 
  collec- 
  

   tions 
  are 
  of 
  particular 
  interest 
  in 
  that 
  they 
  include 
  specimens 
  showing 
  

   sexual 
  epitokous 
  stages 
  of 
  some 
  of 
  the 
  syllids. 
  Considerable 
  care 
  

   was 
  taken 
  in 
  going 
  over 
  the 
  miscellaneous 
  material 
  and 
  separating 
  

   polychaetes, 
  as 
  evidenced 
  by 
  the 
  large 
  collection 
  and 
  the 
  presence 
  

   in 
  it 
  of 
  many 
  small 
  specimens 
  of 
  the 
  young 
  of 
  larger 
  species 
  as 
  well 
  

   as 
  small 
  species 
  which 
  are 
  often 
  overlooked. 
  There 
  are 
  a 
  great 
  num- 
  

   ber 
  of 
  small 
  syllids, 
  phyllodocids, 
  hesionids, 
  and 
  terebeUids. 
  Great 
  

   care 
  also 
  was 
  taken 
  in 
  the 
  preservation 
  of 
  the 
  specimens. 
  Some 
  

   color 
  notes 
  were 
  included 
  and 
  some 
  color 
  photographs 
  were 
  taken, 
  and 
  

   these 
  added 
  considerably 
  to 
  the 
  value 
  of 
  the 
  collection. 
  

  

  The 
  material 
  was 
  worked 
  on 
  by 
  the 
  writer 
  at 
  the 
  U. 
  S. 
  National 
  

   Museum, 
  where 
  the 
  collection 
  is 
  deposited.
