  subequal 
  to 
  each 
  other 
  in 
  length, 
  very 
  slender, 
  with 
  short 
  

   spines 
  on 
  the 
  outer 
  curve 
  and 
  longer 
  ones 
  on 
  the 
  inner. 
  

   Uropod 
  2 
  (fig. 
  9) 
  : 
  peduncle 
  much 
  shorter 
  and 
  nearly 
  twice 
  

   as 
  stout 
  as 
  that 
  of 
  uropod 
  1 
  ; 
  rami 
  subequal 
  to 
  it 
  in 
  length; 
  

   the 
  inner 
  ramus, 
  of 
  the 
  form 
  characteristic 
  of 
  the 
  genus, 
  is 
  

   much 
  longer 
  and 
  narrower 
  than 
  in 
  longipes 
  ; 
  it 
  is 
  actually 
  of 
  

   the 
  same 
  length 
  as 
  the 
  outer 
  ramus, 
  but 
  appears 
  shorter 
  

   through 
  being 
  inset 
  at 
  a 
  different 
  level. 
  Uropod 
  3 
  (fig. 
  10) 
  : 
  

   peduncle 
  broad, 
  shorter 
  than 
  the 
  rami; 
  inner 
  ramus 
  slightly 
  

   the 
  shorter, 
  margin 
  serrated, 
  furnished 
  with 
  sensory 
  spines 
  

   and 
  1 
  plumose 
  seta 
  proximally 
  ; 
  outer 
  ramus 
  2-jointed, 
  outer 
  

   margin 
  with 
  spines, 
  inner 
  margin 
  serrate, 
  with 
  3 
  long 
  

   plumose 
  setae; 
  a 
  setule 
  in 
  each 
  apex. 
  

  

  Telson 
  (fig. 
  11). 
  — 
  The 
  sixth 
  pleon-segment 
  is 
  produced 
  in 
  

   an 
  acute 
  process 
  on 
  either 
  side 
  of 
  the 
  telson 
  ; 
  in 
  longipes 
  these 
  

   processes 
  are 
  shorter 
  an 
  1 
  rounded. 
  

  

  It 
  tapers 
  distally 
  ; 
  cleft 
  to 
  nearly 
  three-quarters 
  the 
  length 
  ; 
  

   apices 
  serrate 
  on 
  the 
  inner 
  side, 
  each 
  with 
  1 
  strong 
  spine 
  

   inset 
  ; 
  a 
  pair 
  of 
  mobile 
  ciliated 
  hairs 
  on 
  either 
  side 
  of 
  the 
  

   cleft. 
  There 
  were 
  6 
  spines 
  on 
  one 
  side 
  in 
  the 
  largest 
  female 
  

   examined, 
  4 
  on 
  the 
  other 
  (probably 
  two 
  have 
  been 
  broken 
  

   off), 
  but 
  the 
  number 
  is 
  less 
  in 
  the 
  smaller 
  specimens.
