  Mcera 
  truncatipes 
  (Spinola) 
  described 
  by 
  Mr. 
  Spence 
  Bate* 
  ; 
  but 
  ia 
  

   that 
  species 
  (and 
  also, 
  it 
  would 
  appear, 
  in 
  M. 
  quadrimanns, 
  Daua, 
  

   from 
  the 
  Fijis, 
  and 
  in 
  M. 
  viridis, 
  Haswell, 
  from 
  the 
  East- 
  Australian 
  

   coast) 
  the 
  hands 
  are 
  similar 
  and 
  the 
  segments 
  of 
  the 
  postabdomcu 
  

   smooth. 
  It 
  is 
  nearlj^ 
  allied 
  to 
  M. 
  rawsai/i, 
  Haswell, 
  referred 
  to 
  in 
  

   the 
  earlier 
  part 
  of 
  this 
  lleport, 
  which, 
  however, 
  differs 
  in 
  the 
  form 
  

   of 
  the 
  hands 
  of 
  the 
  second 
  pair 
  of 
  legs 
  (which 
  have 
  not 
  the 
  deep 
  

   notch 
  of 
  31. 
  diversimanus, 
  and 
  are 
  armed 
  with 
  three 
  nearly 
  equal 
  

   teeth), 
  and 
  also 
  in 
  the 
  larger 
  posterior 
  pleopoda, 
  &c. 
  ; 
  yet 
  it 
  is 
  

   possible 
  that 
  a 
  larger 
  series 
  of 
  specimens 
  would 
  be 
  found 
  to 
  offer 
  

   transitional 
  characters 
  serving 
  to 
  unite 
  the 
  two 
  forms. 
  I 
  may 
  note 
  

   here 
  that 
  there 
  is 
  in 
  the 
  British-Museum 
  collection 
  a 
  specimen 
  from 
  

   the 
  Corean 
  Seas 
  {Capt. 
  IL 
  G. 
  St. 
  Johi) 
  which 
  cannot, 
  I 
  think, 
  be 
  

   distinguished 
  specifically 
  from 
  M. 
  truncatipes 
  (Spinola).
