  without 
  locality, 
  and 
  being 
  also 
  of 
  very 
  small 
  size, 
  I 
  was 
  uncer- 
  

   tain, 
  whether 
  to 
  regard 
  them 
  as 
  belonging 
  at 
  all 
  to 
  this 
  genus, 
  and 
  

   if 
  so, 
  whether 
  they 
  might 
  not 
  represent 
  an 
  immature 
  condition 
  of 
  

   one 
  of 
  the 
  known 
  species. 
  This, 
  I 
  am 
  inclined 
  to 
  think, 
  cannot 
  be 
  

   possible, 
  since 
  there 
  are 
  one 
  or 
  two 
  Matatce 
  in 
  the 
  collection 
  no 
  

   ku'ger 
  than 
  M. 
  inennis, 
  in 
  which 
  nevertheless 
  the 
  lateral 
  spines 
  are 
  

   distinctly 
  developed 
  and 
  the 
  carapace 
  of 
  the 
  normal 
  width. 
  In 
  

   the 
  obsolescence 
  of 
  the 
  lateral 
  spines 
  31. 
  inennis 
  resembles 
  the 
  genus 
  

   C 
  ryptosoma 
  ; 
  but 
  in 
  the 
  form 
  of 
  the 
  chelipedes 
  and 
  of 
  the 
  dactyli 
  of 
  

   the 
  swimming-legs 
  and 
  in 
  the 
  mouth-organs 
  it 
  is 
  altogether 
  a 
  Matuta.

  An 
  adult 
  male 
  was 
  obtained 
  near 
  Clairmont 
  on 
  a 
  coral-reef 
  

   (No. 
  151). 
  

  

  Specimens 
  are 
  in 
  the 
  British-Museum 
  collection

   Australian 
  localities

   this 
  common 
  species, 
  which

  To 
  this 
  species 
  are 
  referred 
  a 
  male 
  from 
  Port 
  Molle, 
  14 
  fms. 
  (No. 
  

   93) 
  ; 
  another 
  from 
  Port 
  Denison, 
  4 
  fms. 
  ; 
  a 
  female 
  from 
  Flinders, 
  

   Clairmont, 
  N.E. 
  Australia, 
  11 
  fms. 
  ; 
  and 
  a 
  small 
  male 
  in 
  very 
  im- 
  

   perfect 
  condition 
  from 
  Thursday 
  Island, 
  4-6 
  fms. 
  (No. 
  130), 
  in 
  

   which 
  the 
  carapace 
  is 
  narrower 
  than 
  usual. 
  All 
  of 
  the 
  above 
  from 
  the 
  

   first 
  collection. 
  In 
  the 
  second 
  collection, 
  three 
  small 
  specimens 
  from 
  

   the 
  Arafura 
  Sea, 
  32-36 
  fms. 
  (No. 
  160), 
  probably 
  belong 
  here. 
  

   Another 
  very 
  small 
  example 
  from 
  Friday 
  Island, 
  10 
  fms. 
  (No. 
  153), 
  

   which 
  has 
  the 
  carapace 
  glabrous, 
  but 
  tuberculatcd 
  nearly 
  as 
  in 
  D. 
  

   dorsipes, 
  I 
  cannot 
  assign 
  with 
  certainty 
  to 
  any 
  species.
