  This

  is 
  added 
  to

  on 
  the 
  authority 
  of 
  

   Metzger, 
  who 
  records 
  a 
  specimen 
  taken 
  at 
  the 
  above-named 
  

   locality 
  by 
  the

  during 
  the 
  German 
  North-Sea

  Aceros 
  phyllonyx 
  may 
  be 
  distinguished 
  from 
  all 
  other 
  

   British 
  CEdiceridaj 
  by 
  the 
  total 
  absence 
  of 
  rostrum 
  ; 
  and 
  also 
  

   from 
  Halimedon, 
  to 
  which 
  it 
  approaches 
  nearest 
  in 
  the 
  form 
  

   of 
  the 
  gnathopods, 
  by 
  the 
  structure 
  of 
  the 
  antennules. 
  

  

  The 
  figures 
  of 
  Bruzelius 
  of 
  the 
  female 
  are 
  very 
  good 
  and 
  

   should 
  be 
  consulted. 
  

  

  Herr 
  H. 
  J. 
  Hansen 
  has 
  recently 
  described 
  a 
  very 
  closely 
  

   allied 
  form 
  from 
  Greenland, 
  Aceros 
  distinguendus 
  (J.

  It 
  is 
  distinguished 
  by 
  the 
  

   much 
  shorter 
  joints 
  of 
  the 
  antennules 
  and 
  the
