  which 
  it 
  may 
  be 
  distinguished 
  from 
  T 
  . 
  ferruginea 
  , 
  Latreille, 
  i. 
  e. 
  by 
  

   the 
  more 
  acute 
  lateral 
  spines 
  of 
  the 
  carapace, 
  and 
  the 
  subcristate 
  and 
  

   hairy 
  palms 
  of 
  the 
  chclipedes, 
  and 
  these 
  characters 
  are 
  remarkably 
  

   constant 
  in 
  adult 
  examples 
  ; 
  but 
  young 
  and 
  half-grown 
  specimens 
  

   can 
  scarcely 
  be 
  distinguished 
  except 
  by 
  the 
  subcristate 
  hands. 
  Since 
  

   the 
  publication 
  of 
  that 
  paper, 
  a 
  specimen 
  has 
  been 
  added 
  to 
  the 
  

   Museum 
  collection 
  from 
  Amboina 
  (Br.

  in 
  the 
  collection 
  from 
  the 
  Seychelles, 
  4—12 
  

   fms. 
  (No.

  Since 
  1878 
  specimens 
  from 
  Ceylon, 
  Galle 
  (Dr. 
  W. 
  Ondaatje), 
  and 
  

   Honolulu 
  (found 
  among 
  fishes 
  of 
  the 
  collection 
  of 
  H.M.S. 
  ' 
  Chal- 
  

   lenger 
  ') 
  have 
  been 
  added 
  to 
  the 
  Museum 
  collection.

  Trapezia 
  rufopunctata 
  (Herbst). 
  

  

  Etoile 
  Island, 
  13 
  fms. 
  (No. 
  191), 
  ten 
  specimens 
  of 
  varying 
  ages 
  

   and 
  both 
  sexes 
  ; 
  Glorioso 
  Islands, 
  7-10 
  fms. 
  (No. 
  219), 
  an 
  adult 
  

   male. 
  

  

  Specimens 
  are 
  in 
  the 
  British-Museum 
  collection 
  from 
  the 
  Mau 
  

   ritius 
  ; 
  Madagascar,

  ;

  of

  {11. 
  MacAndrciv) 
  ; 
  

   and 
  Ceylon 
  {E. 
  W. 
  H. 
  Holdstuorth). 
  It 
  is 
  distributed, 
  as 
  I 
  have 
  

   already 
  noted, 
  throughout 
  the 
  Oriental 
  Region. 
  

  

  This 
  species, 
  as 
  has 
  been 
  repeatedly 
  observed, 
  varies 
  much 
  in 
  the 
  

   size 
  and 
  degree 
  of 
  acuteness 
  of 
  the 
  frontal 
  teeth, 
  and 
  in 
  the 
  size 
  and 
  

   number 
  of 
  the 
  red 
  spots 
  with 
  which 
  the 
  body 
  is 
  covered. 
  The 
  

   specimens 
  from 
  Etoile 
  Island 
  are 
  mostly 
  of 
  tbe 
  variety 
  designated 
  

   by 
  Dana 
  T. 
  maculata 
  of 
  MacLcay 
  *, 
  for 
  which 
  Riippell's 
  name 
  

   T. 
  guttata 
  is 
  an 
  earlier 
  and 
  safer 
  appellation 
  t, 
  characterized 
  by 
  the 
  

   less 
  prominent 
  and 
  acute 
  frontal 
  lobes 
  and 
  smaller 
  spots 
  on 
  the 
  body 
  

   and 
  legs. 
  The 
  latter 
  is 
  not 
  a 
  character 
  dependent 
  upon 
  the 
  age 
  of 
  

   the 
  individual, 
  since 
  in 
  the 
  smallest 
  example 
  from 
  Etoile, 
  length 
  of 
  

   carapace 
  only 
  2| 
  lines 
  (5 
  millim.), 
  the 
  spots 
  are 
  as 
  large 
  as 
  in 
  the 
  

   adult 
  and 
  large 
  example 
  from 
  the 
  Glorioso 
  group. 
  Another 
  speci- 
  

   men 
  from 
  Etoile 
  exhibits 
  an 
  intermediate 
  condition 
  in 
  its 
  markings, 
  

   since 
  several 
  small 
  spots 
  are 
  intermingled 
  with 
  the 
  larger 
  ones.
