  The

  ramus 
  of 
  the 
  posterior 
  antenuce 
  is 
  very 
  small, 
  

   slender,

  slender 
  and 
  elongated, 
  inner 
  

   ramus 
  rather 
  longer 
  than 
  the

  joint 
  ot 
  the

   and 
  both 
  rami 
  are 
  armed 
  with 
  short 
  and 
  stout

  The

  three 
  pairs 
  normal, 
  'J'he 
  fifth 
  pair 
  are 
  of 
  

   moderate 
  size, 
  tlie

  Male. 
  — 
  The 
  male 
  is 
  rather 
  smaller 
  than 
  the 
  female 
  and 
  

   with 
  the 
  antennules 
  modified 
  for 
  grasping. 
  The 
  outer 
  

   ramus 
  of 
  the 
  second 
  pair 
  of 
  thoracic 
  legs 
  is 
  stout 
  and 
  the 
  

   joints 
  are 
  subequal, 
  but 
  the 
  middle 
  one 
  is 
  slightly 
  larger 
  

   than 
  the 
  first 
  or 
  third 
  ; 
  the 
  third 
  joint 
  has 
  also 
  the 
  extremity 
  

   abruptly 
  and 
  somewhat 
  obliquely 
  truncated 
  ; 
  the 
  inner 
  ramus 
  

   is 
  about 
  as 
  long 
  as 
  the 
  outer, 
  but 
  is 
  not 
  so 
  stout, 
  and 
  the 
  

   seconxl 
  joint 
  is 
  produced 
  on 
  its 
  inner 
  aspect 
  into 
  a 
  long 
  

   spiniform 
  process 
  extending 
  beyond 
  the 
  end 
  joint, 
  which 
  is 
  

   small 
  and 
  narrow. 
  The 
  rami 
  of 
  the 
  third 
  pair 
  are 
  also 
  nearly 
  

   equal 
  in 
  length, 
  but 
  the 
  outer 
  is 
  somewhat 
  longer 
  than 
  the 
  

   inner 
  and 
  tolerably 
  stout, 
  the 
  proximal 
  joint 
  is 
  rather 
  longer 
  

   than 
  the 
  others, 
  and 
  the 
  end 
  joint 
  is 
  obliquely 
  truncated; 
  

   the 
  inner 
  ramus 
  is 
  moderately 
  slender. 
  Fifth 
  pair 
  \\ith 
  the 
  

   proximal 
  joint 
  obsolete 
  or 
  nearly 
  so 
  ; 
  the 
  end 
  joint 
  is 
  oblong 
  

   and 
  its 
  width 
  equal 
  to 
  rather 
  more 
  than 
  half 
  the 
  length 
  ; 
  the 
  

   end 
  is 
  broadly 
  rounded 
  and 
  furnished 
  with 
  five 
  elongated 
  

   setse, 
  four 
  of 
  them 
  being 
  tolerably 
  stout 
  and 
  spiniform 
  ; 
  the 
  

   margins 
  of 
  the 
  joint 
  are 
  also 
  fringed 
  with 
  small 
  spinules
