  its 
  lateral 
  margin 
  armed 
  with 
  about 
  8 
  spinules; 
  the 
  joints 
  of 
  the 
  

   chelipedes 
  also 
  spiuulose 
  and 
  hairj' 
  ; 
  fingers 
  rather 
  shorter 
  than 
  the 
  

   palm, 
  minutely 
  denticulated 
  on 
  their 
  inner 
  margins, 
  not 
  gaping 
  when 
  

   closed, 
  with 
  the 
  tips 
  incurved 
  ; 
  the 
  merus- 
  and 
  carpus-joints 
  of 
  the 
  

   first 
  and 
  second 
  ambulatory 
  legs 
  are 
  spinulose 
  on 
  their 
  anterior 
  mar- 
  

   gins 
  ■ 
  and 
  one 
  of 
  the 
  denticules 
  of 
  the 
  inferior 
  margin 
  of 
  the 
  terminal 
  

   joint 
  is 
  more 
  prominent 
  than 
  the 
  others. 
  

  

  If 
  the 
  Australian 
  specimen 
  does 
  not 
  belong 
  to 
  G. 
  elef/ans, 
  it 
  may 
  

   be 
  referable 
  to 
  G. 
  lomprostris, 
  Dana*, 
  from 
  the 
  Fijis, 
  which 
  is 
  very 
  

   incompletely 
  known, 
  which 
  it 
  resembles 
  in 
  the 
  minute 
  serrulatioa 
  of 
  

   the 
  carapace 
  and 
  rostrum 
  and 
  the 
  shorter 
  fingers 
  of 
  the 
  chelipedes, 
  

   which 
  are 
  not, 
  however, 
  less 
  than 
  half 
  the 
  length 
  of 
  the 
  palms, 
  as 
  in 
  

   Dana's 
  description. 
  

  

  In 
  more 
  than 
  one 
  of 
  the 
  specimens 
  in 
  the 
  Museum 
  collection 
  

   the 
  rostrum 
  is 
  slightly 
  deflexed, 
  and 
  I 
  think 
  it 
  probable 
  that 
  G. 
  de- 
  

   Jlexifrons, 
  Haswell 
  (Cat. 
  p. 
  163), 
  from 
  Albany 
  Passage 
  (H.M.S. 
  

   '■Jlert'), 
  should 
  be 
  regarded 
  merely 
  as 
  a 
  marked 
  variety 
  of 
  G. 
  elegans. 
  

  

  23. 
  Munida 
  spinulifera. 
  (Plate 
  XXXI. 
  fig. 
  B.) 
  

  

  This 
  species 
  is 
  evidently 
  nearly 
  allied 
  to 
  Munida 
  japonica, 
  Stimp- 
  

   son 
  ; 
  and 
  it 
  will 
  suffice 
  here 
  to 
  allude 
  to 
  the 
  distinctive 
  characters 
  

   and 
  some 
  other 
  points 
  not 
  mentioned 
  in 
  Stimpson's 
  description. 
  As 
  

   in 
  M. 
  japonica, 
  the 
  anterior 
  part 
  of 
  the 
  gastric 
  region 
  is 
  armed 
  with 
  

   a 
  transverse 
  series 
  of 
  thirteen 
  spinules. 
  On 
  the 
  sides 
  of 
  the 
  cara- 
  

   pace, 
  at 
  a 
  short 
  distance 
  behind 
  the 
  spine 
  at 
  the 
  outer 
  orbital 
  angle, 
  

   is 
  usually 
  a 
  single 
  small 
  spinule 
  (whereas 
  Stimpson, 
  in 
  his 
  descrip- 
  

   tiom 
  of 
  31. 
  jap)onic((, 
  says, 
  " 
  Regie 
  gastrica 
  superficie 
  utrinque 
  tri- 
  

   spinulosa"). 
  On 
  the 
  front 
  of 
  the 
  branchial 
  regions, 
  just 
  behind 
  the 
  

   cervical 
  suture, 
  is 
  another 
  small 
  spinule 
  not 
  mentioned 
  by 
  Mr. 
  

   Stimpson. 
  The 
  lateral 
  margins 
  of 
  the 
  carapace 
  have 
  about 
  seven 
  

   spinules, 
  inclusive 
  of 
  the 
  outer 
  orbital 
  spine, 
  which 
  is 
  rather 
  

   long. 
  

  

  The 
  median 
  spine 
  of 
  the 
  rostrum 
  (in 
  the 
  specimens 
  I 
  have 
  exa- 
  

   mined) 
  is 
  considerably 
  more 
  than 
  twice 
  the 
  length 
  of 
  the 
  lateral 
  

   spines, 
  and 
  is 
  arcuated, 
  with 
  scarcely 
  any 
  trace 
  of 
  lateral 
  denticula- 
  

   tions. 
  The 
  second 
  postabdominal 
  segment 
  has 
  several 
  spinules 
  on 
  

   its 
  upper 
  surface 
  on 
  the 
  anterior 
  margin. 
  The 
  merus, 
  carpus, 
  

   and 
  penultimate 
  joints 
  of 
  the 
  ambulatory 
  legs 
  are 
  spinulose 
  ; 
  the 
  

   spinules 
  on 
  the 
  penultimate 
  joints 
  usually 
  developed 
  only 
  on 
  the 
  

   posterior 
  (or 
  inferior) 
  margins. 
  

  

  Three 
  specimens, 
  of 
  which 
  one 
  (the 
  only 
  one 
  having 
  a 
  chelipede) 
  

   is 
  a 
  male, 
  the 
  two 
  others 
  females 
  with 
  ova, 
  were 
  obtained 
  in 
  the 
  

   Arafura 
  Sea, 
  32-36 
  fms. 
  (jS^o. 
  16U).

  the 
  specimen 
  of 
  M. 
  japonica 
  from 
  the 
  Corean 
  Straits,
