  Most 
  abundant 
  from 
  1300 
  to 
  

   1500 
  fath. 
  In 
  one 
  doubtful 
  case, 
  recorded 
  from 
  471 
  fath. 
  (one 
  

   specimen).

  Allied

  at

  Thomson,

  the

  Atlantic,

  fath., 
  

   and 
  Z. 
  Ackleyi 
  Per., 
  from 
  the 
  West 
  Indies, 
  are 
  nearly 
  related 
  

   to 
  our 
  species 
  if 
  not 
  identical. 
  Mr. 
  Sladen 
  refers 
  specimens 
  

   dredged 
  by 
  the 
  Challenger 
  off 
  our 
  coast 
  in 
  1250 
  to 
  1350 
  fath. 
  

   to 
  Z. 
  fulgens. 
  These 
  were 
  probably 
  identical 
  with 
  our 
  species 
  

   and 
  indicate 
  that 
  the 
  two 
  described 
  forms 
  may 
  be 
  the 
  same.
