  polychaete 
  collections, 
  which 
  include 
  much 
  type 
  material, 
  were 
  placed 
  

   at 
  the 
  writer's 
  disposal. 
  Some 
  previously 
  unworked 
  material 
  was 
  

   examined 
  for 
  comparative 
  purposes, 
  and 
  the 
  results 
  of 
  some 
  of 
  these 
  

   related 
  studies 
  are 
  included 
  here. 
  This 
  material 
  is 
  chiefly 
  from 
  collec- 
  

   tions 
  made 
  by 
  the 
  following: 
  R. 
  A. 
  Bartlett 
  in 
  the 
  Canadian 
  Arctic, 
  

   Greenland, 
  and 
  Labrador 
  from 
  1927 
  to 
  1942; 
  W. 
  H. 
  Dall 
  in 
  Arctic 
  

   Alaska, 
  the 
  Bering 
  Sea, 
  and 
  southeastern 
  Alaska 
  from 
  1871 
  to 
  1880; 
  

   the 
  Blue 
  Dolphin 
  expeditions 
  to 
  Labrador 
  and 
  Newfoundland 
  from 
  

   1949 
  to 
  1951 
  under 
  the 
  command 
  of 
  D. 
  C. 
  Nutt; 
  the 
  U. 
  S. 
  Fish 
  Com- 
  

   mission 
  in 
  dredgings 
  off 
  the 
  east 
  coast 
  of 
  North 
  America, 
  from 
  which 
  

   many 
  specimens 
  had 
  been 
  identified 
  and 
  recorded 
  by 
  A. 
  E. 
  Verrill; 
  

   and 
  by 
  the 
  writer 
  in 
  the 
  Straits 
  of 
  Juan 
  de 
  Fuca, 
  in 
  Washington 
  and 
  

   Puget 
  Sounds, 
  Washington, 
  chiefly 
  during 
  the 
  summers 
  from 
  1936 
  to 
  

   1940, 
  and 
  from 
  the 
  region 
  of 
  Woods 
  Hole, 
  Massachusetts, 
  in 
  the 
  

   summers 
  of 
  1950 
  and 
  1951. 
  For 
  the 
  last 
  three 
  collections 
  mentioned, 
  

   only 
  summaries 
  of 
  the 
  data 
  are 
  given 
  for 
  species 
  common 
  to 
  the 
  

   Point 
  Barrow 
  region. 
  More 
  complete 
  data 
  are 
  to 
  be 
  published 
  sepa- 
  

   rately 
  and 
  the 
  summaries 
  are 
  included 
  here 
  only 
  to 
  make 
  the 
  dis- 
  

   tributional 
  data 
  of 
  the 
  Point 
  Barrow 
  species 
  more 
  complete. 
  

  

  The 
  number 
  of 
  polychaetes 
  previously 
  recorded 
  from 
  Arctic 
  Alaska 
  

   is 
  smaU 
  indeed. 
  The 
  collection 
  obtained 
  by 
  the 
  International 
  Polar 
  

   Expedition 
  to 
  Point 
  Barrow 
  from 
  1881 
  to 
  1883 
  included 
  only 
  17 
  poly- 
  

   chaetes 
  (Murdoch, 
  1885, 
  p. 
  152). 
  This 
  collection, 
  which 
  was 
  depos- 
  

   ited 
  in 
  the 
  U. 
  S. 
  National 
  Museum, 
  was 
  examined 
  by 
  the 
  writer 
  and 
  

   is 
  referred 
  to 
  in 
  this 
  report. 
  A 
  few 
  additional 
  records 
  in 
  scattered 
  

   papers 
  have 
  added 
  to 
  the 
  list 
  of 
  polychaetes 
  of 
  Arctic 
  Alaska. 
  

  

  For 
  each 
  of 
  the 
  species, 
  a 
  rather 
  full 
  but 
  by 
  no 
  means 
  complete 
  

   synonymy 
  is 
  given, 
  chiefly 
  bringing 
  together 
  references 
  to 
  the 
  original 
  

   and 
  additional 
  descriptions 
  and 
  scattered 
  distributional 
  records. 
  To 
  

   facilitate 
  identification, 
  keys 
  to 
  the 
  families, 
  genera, 
  and 
  species 
  are 
  

   given, 
  as 
  well 
  as 
  synopses 
  of 
  the 
  families 
  and 
  brief 
  descriptions 
  of 
  the 
  

   species 
  with 
  size 
  ranges 
  and 
  color 
  notes. 
  An 
  explanatory 
  key 
  to 
  the 
  

   lettering 
  of 
  the 
  diagnostic 
  features 
  in 
  the 
  figures 
  is 
  given 
  on 
  page

  This 
  study 
  was
