   Specimens 
  examined. 
  

  

  Some 
  of 
  these 
  specimens 
  show 
  that 
  the 
  dactyli 
  of 
  the 
  fourth 
  aud 
  fifth 
  

   perseopods 
  are, 
  as 
  I 
  had 
  supposed, 
  norinalty 
  very 
  slender, 
  but 
  not 
  multi- 
  

   articulate 
  nor 
  very 
  long 
  in 
  either 
  sex, 
  and 
  that 
  the 
  tiagella 
  of 
  the 
  an- 
  

   tennula 
  are 
  very 
  long, 
  apparently 
  much 
  longer 
  than 
  the 
  body. 
  

  

  Benthoneotes 
  Smith. 
  

  

  This 
  genus 
  is 
  closely 
  allied 
  to 
  Benthcecetes 
  and 
  is 
  specially 
  charaterized 
  

   by 
  the 
  multiarticulate 
  flagelliform 
  dactyli 
  of 
  the 
  fourth 
  and 
  fifth 
  perceo- 
  

   pods. 
  It 
  is 
  further 
  distinguished 
  from 
  allied 
  genera 
  by 
  the 
  acute 
  ventral 
  

   process 
  of 
  the 
  crowns 
  of 
  the 
  maudibles 
  and 
  the 
  narrow 
  mandibular 
  palpi 
  ; 
  

   aud 
  probably, 
  also, 
  by 
  the 
  presence 
  of 
  a 
  hepatic 
  spine 
  upon 
  tbe 
  cara- 
  

   pax, 
  the 
  large 
  reniform 
  eyes, 
  the 
  equal 
  lobes 
  of 
  the 
  protognath 
  of 
  the 
  

   second 
  rnaxillse, 
  the 
  absence 
  or 
  obsolescence 
  of 
  the 
  third 
  segment 
  of 
  the 
  

   endopod 
  of 
  the 
  maxilliped, 
  the 
  narrow 
  merus 
  of 
  the 
  first 
  gnathopod, 
  and 
  

   the 
  styliform 
  dactylus 
  of 
  the 
  second 
  gnathopod. 
  Like 
  that 
  of 
  Benthoe- 
  

   cetes, 
  the 
  relation 
  to 
  Bate's 
  imperfectly 
  described 
  Benthesicymns 
  is 
  large-
