  COLLECTIONS 
  FEOM 
  MELANESIA. 
  

  

  specimens 
  in 
  the 
  British-Museum 
  collection 
  scarcely 
  any 
  traces 
  

   exist 
  of 
  the 
  meral 
  spines 
  above 
  mentioned. 
  I 
  may 
  add 
  that 
  I 
  

   have 
  observed 
  a 
  considerable 
  degree 
  of 
  variation 
  in 
  the 
  length 
  of 
  

   the 
  rostrum 
  in 
  the 
  large 
  series 
  of 
  specimens 
  of 
  this 
  species 
  in 
  the 
  

   collection 
  of 
  the 
  British 
  Museum. 
  In 
  the 
  type 
  specimen 
  of 
  Egeria 
  

   indica 
  of 
  Leach 
  in 
  this 
  collection 
  the 
  third 
  joint 
  of 
  the 
  outer 
  maxil- 
  

   lipede 
  does 
  not 
  in 
  reality 
  present 
  any 
  peculiarity 
  of 
  form, 
  nor 
  does 
  

   this 
  specimen 
  differ 
  from 
  ordinary 
  adult 
  examples 
  of 
  the 
  genus. 
  

  

  I 
  believe, 
  then, 
  it 
  will 
  be 
  necessary 
  to 
  unite 
  under 
  one 
  specific 
  

   designation 
  the 
  three 
  forms 
  Er/eria 
  arachnoides, 
  E. 
  herbstii, 
  and 
  

   E. 
  indica, 
  mentioned 
  by 
  Milne-Edwards*, 
  and 
  that 
  to 
  this 
  species 
  

   the 
  name 
  arachnoides 
  must 
  be 
  applied 
  rather 
  than 
  the 
  Linnean 
  

   designation 
  longipes, 
  because 
  Linnteus's 
  description 
  of 
  his 
  Cancer 
  

   longipes 
  f 
  differs 
  in 
  several 
  particulars 
  from 
  Egeria 
  arachnoides 
  ; 
  

   thus 
  he 
  says 
  " 
  manus 
  ovatce, 
  muricatce," 
  or 
  " 
  scabrce," 
  whereas 
  in 
  

   Egeria 
  arachnoides 
  the 
  hands 
  are 
  always 
  elongated 
  and 
  smooth 
  ; 
  

   moreover, 
  in 
  the 
  middle 
  line 
  of 
  the 
  carapace 
  are 
  five 
  (not 
  four) 
  

   tubercles 
  or 
  short 
  spines 
  ; 
  other 
  distinctions 
  might 
  be 
  mentioned. 
  

  

  Specimens 
  of 
  Egeria 
  arachnoides 
  are 
  in 
  the 
  Museum 
  collection 
  

   from 
  the 
  Indian 
  Ocean 
  (Hardiuicke), 
  Philippine 
  Islands, 
  Zebu 
  

   (Cuming),

   (J.

  &c. 
  ; 
  several 
  other 
  jN^.E. 
  Australian 
  localities 
  are 
  

   recoi'ded 
  by 
  Mr. 
  Haswell. 
  

  

  The 
  species 
  designated 
  Egeria 
  longipes, 
  M.-Edw., 
  by 
  Adams 
  and 
  

   WhiteJ, 
  if 
  correctly 
  characterized, 
  differs 
  from 
  any 
  specimen 
  of 
  the 
  

   genus 
  I 
  have 
  seen 
  in 
  its 
  very 
  much 
  broader, 
  transverse 
  front, 
  and 
  

   may 
  belong 
  to 
  a 
  distinct 
  species.
