  COLLECTION'S 
  FROM 
  MELANESIA, 
  

  

  which 
  differ 
  from 
  the 
  specimen 
  doubtfully 
  referred 
  to 
  A. 
  ffracilipes, 
  

   from 
  Capt. 
  St. 
  John's 
  Coreau 
  collection, 
  in 
  the 
  British 
  Museum* 
  

   only 
  in 
  having 
  the 
  inferior 
  margins 
  of 
  the 
  merus-joint 
  of 
  the 
  larger 
  

   chelipede 
  distinctly 
  serrated 
  and 
  its 
  upper 
  margin 
  bluntly 
  angulated 
  

   at 
  the 
  distal 
  end, 
  whereas 
  in 
  the 
  Corean 
  specimen 
  the 
  inferior 
  mar- 
  

   gins 
  are 
  nearly 
  smooth 
  and 
  the 
  upper 
  margin 
  ends 
  in 
  a 
  distinct 
  

   spine. 
  A 
  specimen 
  from 
  Ceylon 
  (E. 
  W. 
  H. 
  Holdsivorth) 
  is 
  somewhat 
  

   intermediate 
  in 
  these 
  characters. 
  Nothing 
  is 
  said 
  regarding 
  the 
  

   form 
  of 
  this 
  joint 
  by 
  Stimpson 
  in 
  his 
  original 
  description. 
  I 
  may 
  

   add 
  that 
  both 
  the 
  Japanese 
  and 
  Australian 
  specimens 
  differ 
  from 
  

   Stimpson's 
  description, 
  founded 
  on 
  examples 
  from 
  Tahiti, 
  in 
  having 
  

   the 
  first 
  joint 
  of 
  the 
  carpus 
  a 
  little 
  shorter 
  than 
  the 
  second.

  Three 
  specimens, 
  of 
  which 
  two 
  are 
  females 
  with 
  ova, 
  were 
  ob- 
  

   tained 
  at 
  Thursday 
  Island, 
  4-5 
  fms. 
  (No. 
  165). 
  

  

  A 
  small 
  specimen 
  is 
  in 
  the 
  British-Museum 
  collection 
  from 
  Port 
  

   Jackson, 
  between 
  Bell's 
  Head 
  and 
  Goat 
  Island 
  {J. 
  Brazier). 
  

  

  To 
  this 
  species 
  also 
  are 
  referred 
  specimens 
  from 
  the 
  Gulf 
  of 
  

   Suez 
  {R. 
  IlctcAndretv), 
  Karachi 
  (Karachi 
  Museum), 
  and 
  Ceylon 
  

   (E. 
  W. 
  U. 
  Iloldsivortli), 
  besides 
  three 
  specimens 
  presented 
  by 
  T. 
  

   Say, 
  and 
  therefore 
  of 
  typical 
  value, 
  from 
  East 
  Florida. 
  

  

  Dana's 
  types 
  were 
  from 
  the 
  Sooloo 
  Sea, 
  and 
  Stimpson 
  records 
  it 
  

   from 
  Ousima 
  and 
  Hong 
  Kong. 
  

  

  I 
  can 
  find 
  nothing, 
  either 
  in 
  the 
  descriptions 
  of 
  authors 
  or 
  in 
  iihe 
  

   specimens 
  I 
  have 
  examined, 
  to 
  warrant 
  the 
  s])ecific 
  separation 
  of 
  the 
  

   Oriental 
  from 
  the 
  American 
  species. 
  The 
  ocular 
  spines 
  and 
  rostrum 
  

   are, 
  however, 
  somewhat 
  shorter 
  and 
  more 
  triangulate 
  in 
  the 
  Floridan 
  

   examples 
  than 
  in 
  the 
  Oriental 
  form 
  ; 
  and 
  as 
  Kingsley 
  notes 
  a 
  similar 
  

   distinction 
  between 
  specimens 
  occurring 
  on 
  the 
  Eastern 
  and 
  Western 
  

   American 
  coasts, 
  I 
  retain 
  Dana's 
  name 
  for 
  the 
  Oriental 
  variety. 
  On 
  

   the 
  American 
  coasts 
  it 
  is 
  recorded 
  by 
  Kingsley 
  from 
  North 
  Carolina 
  

   to 
  the 
  Bermudas 
  on 
  the 
  east, 
  and 
  at 
  Pearl 
  Islands 
  Bay, 
  off 
  Panama, 
  

   on 
  the 
  west.
