  the

   is 
  rather

  Two

  in 
  the 
  absence 
  of

  is 
  distinguished 
  from

  the

  the

   and

  In 
  this 
  little 
  species 
  the 
  carapace 
  is 
  scantily 
  hairy, 
  with 
  the 
  

   branchial 
  regions 
  moderately 
  dilated, 
  without 
  any 
  indication 
  of 
  a 
  

   rostrum, 
  and 
  without 
  lateral 
  teeth, 
  and 
  rounded 
  off 
  at 
  the 
  antero- 
  

   lateral 
  angles. 
  The 
  terminal 
  postabdominal 
  segment 
  has 
  its 
  margins 
  

   minutely 
  spinulose, 
  is 
  rounded 
  on 
  the 
  sides, 
  and 
  without 
  a 
  median 
  

   notch. 
  The 
  eye-peduncles 
  are 
  slender, 
  and 
  about 
  as 
  long 
  as 
  the 
  

   width 
  of 
  the 
  frontal 
  margin 
  ; 
  corneae 
  small 
  and 
  not 
  dilated 
  ; 
  oph- 
  

   thalmic 
  scales 
  small, 
  entire, 
  with 
  subacute 
  apices. 
  The 
  basal 
  

   antennal 
  joint 
  is 
  very 
  short, 
  aud 
  has 
  a 
  very 
  small 
  spinulo 
  on 
  its 
  

   outer 
  margin 
  ; 
  the 
  dorsal 
  aciculnm 
  of 
  the 
  following 
  joint 
  is 
  very 
  

   slender, 
  and 
  reaches 
  very 
  nearly 
  to 
  the 
  apex 
  of 
  the 
  eye-peduncles 
  ; 
  

   the 
  flagella 
  nearly 
  naked. 
  The 
  merus-joints 
  of 
  the 
  chelipedes 
  have 
  

   a 
  small 
  spinule 
  at 
  the 
  distal 
  ends 
  of 
  their 
  upper 
  margins 
  ; 
  the 
  wrists 
  

   are 
  hairy, 
  and 
  spinulose 
  above, 
  with 
  a 
  series 
  of 
  more 
  prominent 
  

   spiuules 
  along 
  the 
  inner 
  and 
  upper 
  margins 
  ; 
  the 
  larger 
  (right) 
  chela 
  

   is 
  ovate, 
  scantily 
  hairy, 
  rather 
  swollen 
  within, 
  externally 
  nearly 
  flat, 
  

   with 
  a 
  series 
  of 
  small 
  spinules 
  along 
  its 
  upper 
  and 
  lower 
  margins 
  

   and 
  with 
  some 
  obscurely 
  indicated 
  granules 
  on 
  its 
  outer 
  surface 
  : 
  the 
  

   fingers 
  are 
  shorter 
  than 
  the 
  palm, 
  and 
  have 
  between 
  them 
  a 
  small 
  

   hiatus 
  at 
  base 
  when 
  closed 
  ; 
  the 
  lower 
  is 
  granulated 
  externally 
  ; 
  both 
  

   are 
  spinulose 
  on 
  their 
  outer, 
  and 
  toothed 
  on 
  their 
  inner 
  margins. 
  

   The 
  second 
  and 
  third 
  legs 
  are 
  of 
  moderate 
  length, 
  hairy 
  and 
  smooth 
  

   without 
  spines 
  or 
  tubercles 
  ; 
  the 
  dactyli 
  a 
  trifle 
  shorter 
  than 
  the 
  

   preceding 
  joints 
  ; 
  the 
  fourth 
  legs 
  are 
  short 
  and 
  imperfectly 
  sub- 
  

   chclate 
  (the 
  infero-distal 
  lobe 
  of 
  the 
  penultimate 
  joint 
  being 
  but 
  

   little 
  developed) 
  ; 
  the 
  fifth 
  legs 
  apparently 
  not 
  subchelate, 
  the 
  

   dactyli 
  clothed 
  with 
  long 
  hairs. 
  The 
  uropoda 
  are, 
  as 
  usual, 
  asym- 
  

   metrical 
  ; 
  the 
  rami 
  with 
  a 
  scabrous 
  pad 
  on 
  their 
  outer 
  surfaces. 
  

   Colour 
  (in

  Length 
  of

  3.) 
  lines 
  

   (about 
  7-5 
  millim.), 
  of 
  larger 
  chelipede 
  about 
  Gh 
  lines 
  (13|

   of 
  left 
  ambulatory 
  leg 
  of 
  first 
  pair

  7 
  lines 
  (15 
  millim.). 
  

  

  A 
  single 
  male 
  was 
  obtained 
  in 
  the 
  Arafura 
  Sea 
  (32-36 
  fms.).
