  synonyms 
  by 
  giving 
  a 
  new 
  designation 
  to 
  a 
  female 
  example 
  and 
  one 
  

   so 
  doubtfully 
  distinct, 
  I 
  should 
  add, 
  however, 
  that 
  in 
  Dr. 
  Cop- 
  

   pinger's 
  specimen 
  there 
  is 
  scarcely 
  any 
  trace 
  of 
  pubescence 
  on 
  the 
  

   middle 
  part 
  of 
  the 
  dorsal 
  surface 
  of 
  the 
  carapace, 
  which 
  is 
  probably 
  

   worn 
  smooth 
  by 
  abrasion. 
  

  

  Two 
  females 
  received 
  in 
  the 
  second 
  collection 
  from 
  the 
  same 
  

   locality, 
  16 
  fms. 
  (No. 
  ir37), 
  are 
  of 
  larger 
  size, 
  uniformly 
  tomentose, 
  

   and 
  the 
  maxillipede 
  (in 
  one 
  specimen 
  examined) 
  is 
  less 
  distinctly 
  

   truncated 
  at 
  its 
  distal 
  end 
  ; 
  they 
  cannot, 
  however, 
  be 
  regarded 
  as 
  

   belonging 
  to 
  a 
  distinct 
  species. 
  

  

  93. 
  Mycteris 
  longicarpus, 
  Latr. 
  

  

  Port 
  Molle 
  ; 
  four 
  specimens 
  (two 
  males 
  and 
  two 
  females) 
  were 
  

   obtained 
  on 
  the 
  beach 
  (No. 
  95). 
  

  

  Specimens 
  are 
  in 
  the 
  British- 
  Museum 
  collection 
  from 
  Port 
  Essing- 
  

   ton 
  {J. 
  Gould); 
  Nicoi 
  Bay, 
  N.W. 
  Australia 
  {M. 
  dii 
  Boulay); 
  Sydney; 
  

   Port 
  Jackson 
  {Antarctic 
  Krpedition) 
  ; 
  Swan 
  Eiver 
  (Dring) 
  ; 
  Tasmania 
  

   (li. 
  Gunn) 
  ; 
  and 
  others 
  without 
  special 
  locality. 
  Also 
  from 
  New 
  

   Guinea 
  (i^ey. 
  W. 
  Y. 
  Turner); 
  Billiton 
  Island 
  (il/cn-^ia's 
  of 
  Ttveedclale); 
  

   Timor 
  Laut 
  (H. 
  0. 
  Forbes) 
  ; 
  Philippines, 
  Negros 
  {Cuming) 
  ; 
  and 
  

   China 
  seas 
  {Swinhoe). 
  

  

  It 
  is 
  recorded 
  by 
  M. 
  A. 
  Milne-Edwards 
  from 
  New 
  Caledonia. 
  

  

  I 
  think 
  it 
  is 
  very 
  doubtful 
  whether 
  Mycteris 
  hrtvidacti/lus, 
  Stimp- 
  

   son 
  *, 
  from 
  the 
  Loo-choo 
  Islands, 
  can 
  be 
  regarded 
  as 
  distinct 
  from 
  

   this 
  species. 
  

  

  Of 
  the 
  closely 
  allied 
  Mycteris 
  platycheles, 
  M.-Edwards, 
  there 
  are 
  

   specimens 
  in 
  the 
  British-Museum 
  collection 
  from 
  Broken 
  Bay 
  

   {J. 
  Macgillivray, 
  H.M.S. 
  ' 
  Eattlesnake 
  '), 
  Tasmania 
  {Dring, 
  Lieut. 
  A. 
  

   Smith), 
  and 
  others 
  without 
  special 
  indication 
  of 
  locality. 
  With 
  

   this 
  latter 
  species, 
  Mycteris 
  suhverrucatus 
  of 
  "White 
  t 
  and 
  Kinahan 
  X 
  

   is 
  identical. 
  

  

  94. 
  Halicarcinus 
  ovatus, 
  Stimpson. 
  

  

  Port 
  Jackson, 
  0-7 
  fms. 
  (No. 
  104). 
  Four 
  specimens, 
  two 
  males 
  

   and 
  two 
  females. 
  

  

  In 
  the 
  ' 
  Catalogue 
  of 
  New-Zealand 
  Crustacea,' 
  p. 
  49 
  (] 
  876), 
  I 
  

   united 
  this 
  form 
  with 
  Hcdicarcinus 
  planatus 
  (Eabr.) 
  ; 
  but 
  after 
  a 
  

   closer 
  examination 
  of 
  a 
  larger 
  series 
  of 
  Australian 
  specimens, 
  I 
  was 
  

   inclined 
  to 
  think 
  that 
  it 
  miglit 
  after 
  all 
  be 
  distinctly 
  characterized 
  by 
  

   relatively 
  larger 
  and 
  more 
  closely 
  approximated 
  frontal 
  lobes 
  which 
  

   are 
  less 
  hairy 
  above. 
  Accordingly 
  the 
  citation 
  of 
  this 
  species 
  was 
  

   not 
  included 
  among 
  the 
  synonymical 
  references 
  to 
  //. 
  planatus 
  in 
  

   my 
  notice 
  of 
  that 
  species

  the 
  Eeport

  Crustacea
