  Among 
  a 
  collection 
  of 
  annelids 
  made 
  by 
  Capt. 
  R. 
  A. 
  Bartlett 
  in 
  

   Alaska 
  during 
  the 
  summer 
  of 
  1924, 
  under 
  the 
  auspices 
  of 
  the 
  National 
  

   Geographic 
  Society, 
  and 
  submitted 
  to 
  me 
  for 
  examination 
  by 
  Dr. 
  

   Waldo 
  L. 
  Schmitt 
  of 
  the 
  United 
  States 
  National 
  Museum, 
  was 
  a 
  

   single 
  specimen 
  belonging 
  to 
  the 
  genus 
  Enipo, 
  which 
  apparently 
  

   represents 
  a 
  new 
  species. 
  The 
  specimen 
  is 
  entire, 
  but 
  has 
  lost 
  all 
  of 
  

   its 
  elytra, 
  so 
  that 
  I 
  am 
  unable 
  to 
  gi^e 
  any 
  details 
  of 
  these 
  latter 
  

   organs. 
  

  

  The 
  other 
  annelids 
  represented 
  in 
  the 
  collection 
  were 
  Harmothoe 
  

   imbricata 
  Linnaeus, 
  Eunoe 
  barbata 
  Moore, 
  Nereis 
  pelagica 
  Linnaeus 
  

   and 
  Nephthys, 
  species. 
  The 
  material 
  was 
  dredged 
  at 
  three 
  different 
  

   localities: 
  About 
  15 
  miles 
  north 
  of 
  Big 
  Diomede 
  Island, 
  Bering 
  Strait, 
  

   June 
  14, 
  1924; 
  south 
  of 
  Big 
  Diomede 
  Island, 
  and 
  in 
  the 
  mouth 
  of 
  

   Kotzebue 
  Sound, 
  July 
  10 
  and 
  12, 
  1924, 
  12-17 
  fathoms. 
  From 
  south 
  

   of 
  Big 
  Diomede 
  Island 
  but 
  one 
  mutilated 
  and 
  hence 
  questionably 
  

   determined 
  Nereis 
  pelagica 
  was 
  obtained; 
  otherwise 
  the 
  species 
  were 
  

   found 
  at 
  each 
  of 
  the 
  other 
  localities, 
  except 
  the 
  new 
  species 
  which 
  

   was 
  taken 
  only 
  in 
  Kotzebue 
  Sound, 
  and 
  the 
  fragmentary 
  Nephthys 
  

   from 
  north 
  of 
  Big 
  Diomede 
  Island. 
  

  

  Genus 
  ENIPO 
  Malmgren 
  

  

  ENIPO 
  CIRRATA, 
  new 
  species 
  

  

  The 
  body 
  has 
  a 
  length 
  of 
  38 
  mm. 
  with 
  a 
  prostomial 
  width 
  of 
  1 
  mm. 
  

   and 
  a 
  greatest 
  body 
  width 
  of 
  2 
  mm. 
  ; 
  and 
  contains 
  64 
  somites. 
  There 
  

   are 
  15 
  pairs 
  of 
  elytrophores 
  on 
  somites
