  Specimens 
  examined. 
  

  

  The 
  specimen 
  originally 
  described 
  (5464) 
  was 
  in 
  rather 
  bad 
  condition,, 
  

   and 
  its 
  integument 
  apparently 
  much 
  thinner 
  and 
  softer 
  than 
  in 
  the 
  

   larger 
  and 
  much 
  more 
  perfectly 
  preserved 
  specimens 
  subsequently 
  ob- 
  

   tained. 
  In 
  these 
  later 
  specimens 
  the 
  integument 
  is 
  very 
  much 
  like 
  that 
  

   of 
  Aristeus 
  f 
  tridens, 
  which 
  the 
  species 
  resembles 
  closely 
  in 
  general 
  

   appearance. 
  

  

  In 
  the 
  recently 
  preserved 
  alcoholic 
  specimens, 
  the 
  small 
  rounded 
  tu- 
  

   bercle 
  on 
  the 
  inner 
  side 
  of 
  the 
  eye-stalk 
  is 
  semi-translucent, 
  cornea-like, 
  

   slightly 
  pigmented 
  at 
  the 
  base, 
  receives 
  a 
  branch 
  of 
  the 
  optic 
  nerve, 
  and 
  

   has 
  the 
  appearance 
  of 
  a 
  secondary 
  simple 
  eye. 
  

  

  The 
  peduncles 
  of 
  the 
  anteunulse 
  reach 
  nearly 
  to 
  or 
  a 
  little 
  by 
  the 
  tips 
  of 
  

   the 
  antenna! 
  scales 
  ; 
  the 
  body 
  of 
  the 
  proximal 
  segment 
  is 
  about 
  half
