  Remarks. 
  — 
  Nereis 
  procera 
  Ehlers, 
  1868, 
  originally 
  described 
  from 
  

   the 
  Gulf 
  of 
  Georgia, 
  British 
  Columbia, 
  has 
  been 
  referred 
  to 
  N. 
  zonata 
  

   by 
  Fauvel, 
  1914. 
  In 
  A^. 
  procera 
  the 
  hodj 
  is 
  long, 
  slender, 
  extremely 
  

   attenuated 
  posteriorly; 
  the 
  notopodial 
  ligules 
  of 
  the 
  anterior 
  setigers 
  

   are 
  triangular, 
  subequal; 
  those 
  of 
  the 
  median 
  and 
  posterior 
  regions 
  

   have 
  the 
  upper 
  notopodial 
  ligules 
  larger 
  than 
  the 
  lower 
  one 
  (may 
  be 
  

   nearly 
  twice 
  the 
  size) 
  ; 
  the 
  paragnaths 
  of 
  areas 
  VII 
  and 
  VIII 
  are 
  in 
  a 
  

   wide, 
  continuous 
  area 
  with 
  no 
  especially 
  enlarged 
  anterior 
  row; 
  male 
  

   epitokes 
  with 
  51 
  and 
  females 
  with 
  59 
  prenatatory 
  setigers. 
  It 
  may 
  be 
  

   that 
  the 
  variety 
  procera 
  of 
  Fauvel 
  refers 
  to 
  a 
  different 
  species 
  from 
  that 
  

   of 
  N. 
  procera 
  Ehlers.
