  Specimens 
  examined. 
  

  

  This 
  species 
  should 
  evidently 
  be 
  referred 
  to 
  G. 
  O. 
  Sars's 
  genus 
  Sclero- 
  

   crangorij 
  which 
  includes 
  Ceraphilus 
  boreas 
  and 
  C.ferox. 
  The 
  genus 
  is 
  

   distinguished 
  from 
  the 
  typical 
  species 
  of 
  Ceraphilus 
  by 
  the 
  inner 
  lamel- 
  

   lae 
  of 
  the 
  pleopods 
  being 
  very 
  much 
  smaller 
  than 
  the 
  outer 
  and 
  without 
  

   the 
  stylet 
  on 
  the 
  mesial 
  edge. 
  The 
  thick, 
  rough 
  integument 
  and 
  the 
  

   very 
  slender 
  second 
  peraeopods 
  with 
  minute 
  chelae 
  are, 
  perhaps, 
  also 
  

   characteristic.
