  Remarks. 
  — 
  Eunoe 
  nodosa 
  has 
  been 
  confused 
  with 
  E. 
  oerstedi. 
  The 
  

   two 
  species 
  have 
  been 
  separated 
  by 
  Sars 
  (1860), 
  Malmgren 
  (1865), 
  

   Verrill 
  (1881), 
  Murdoch 
  and 
  Benedict 
  (1885, 
  as 
  Polynoe 
  islandica 
  and 
  

   P. 
  scahru), 
  and 
  Treadwell 
  (1937). 
  They 
  have 
  been 
  considered 
  to 
  be 
  

   synonymous 
  and 
  a 
  highly 
  variable 
  species 
  by 
  Theel 
  (1879), 
  Wiren 
  

   (1883), 
  Fauvel 
  (1923), 
  Ditlevsen 
  (1917), 
  Augener 
  (1928), 
  and 
  Wesen- 
  

   berg-Lund 
  (1950a, 
  b). 
  Based 
  on 
  a 
  study 
  of 
  the 
  material 
  from 
  Point 
  

   Barrow 
  as 
  well 
  as 
  numerous 
  other 
  specimens 
  in 
  the 
  U. 
  S. 
  National 
  

   Museum 
  from 
  Greenland 
  and 
  off 
  New 
  England, 
  the 
  two 
  species 
  appear 
  

   to 
  be 
  separable 
  on 
  the 
  basis 
  of 
  a 
  number 
  of 
  characters 
  as 
  indicated 
  

   in 
  the 
  key. 
  They 
  agree 
  in 
  having 
  the 
  prostomium 
  with 
  cephalic 
  

   peaks 
  short 
  and 
  blunt 
  or 
  lacking, 
  the 
  position 
  of 
  the 
  eyes, 
  the 
  dorsal 
  

   cirri 
  with 
  long 
  papillae, 
  and 
  the 
  palps 
  each 
  with 
  six 
  longitudinal 
  rows 
  

   of 
  papillae.
