  perhaps 
  not

  t 
  The 
  peculiar, 
  conspicuously 
  faceted 
  area 
  on 
  the 
  dorsal 
  side 
  of 
  the 
  eye 
  and 
  near 
  to 
  

   the 
  margin 
  of 
  the 
  cornea 
  proper, 
  and 
  often 
  darker 
  than 
  it, 
  which 
  is 
  conspicuous 
  in 
  

   many 
  Alpheidae 
  and 
  Palaenionidae, 
  is 
  entirely 
  absent 
  in 
  this 
  species. 
  This 
  area, 
  how- 
  

   ever, 
  is 
  also 
  absent 
  in 
  Pandalus 
  propinquus, 
  although 
  it 
  is 
  very 
  conspicuous 
  in 
  P. 
  Mon- 
  

   tagui, 
  leptoctrus, 
  and 
  borealis. 
  For 
  convenience, 
  I 
  refer 
  to 
  this 
  area, 
  in 
  the 
  following 
  

   part 
  of 
  the 
  list,

  the 
  "

  area." 
  

  

  t 
  A 
  single 
  very 
  imperfect 
  specimen 
  of 
  this 
  species, 
  which 
  is 
  very 
  distinct 
  from 
  any 
  

   other 
  in 
  the 
  collections 
  of 
  the 
  Fish 
  Commission, 
  was 
  taken
