  15 
  millim.), 
  Tritliout 
  exact 
  locality 
  (II.3I.S. 
  ' 
  Herald 
  '), 
  the 
  carapace 
  

   has 
  three 
  brilliant 
  jxatches 
  of 
  red 
  — 
  one 
  on 
  either 
  side 
  of 
  the 
  middle 
  

   line 
  on 
  the 
  frontal 
  region, 
  and 
  one 
  on 
  the 
  cardiac 
  region 
  reaching 
  

   to 
  the 
  posterior 
  margin. 
  No 
  trace 
  of 
  this 
  coloration 
  appears 
  in 
  the 
  

   specimen 
  from 
  Darros 
  Island, 
  but 
  in 
  other 
  particulars 
  they 
  are 
  

   closely 
  alike. 
  This 
  species, 
  although 
  rare, 
  has 
  a 
  wide 
  Oriental 
  dis- 
  

   tribution. 
  Stimpson's 
  types 
  were 
  from 
  the 
  island 
  of 
  Ousima, 
  and 
  

   A. 
  M.-Edwards 
  records 
  it 
  from 
  New 
  Caledonia 
  ; 
  Hilgendorf 
  (though 
  

   doubtfully) 
  from 
  Mozambique. 
  By 
  Kossmann 
  {t. 
  c. 
  p. 
  47) 
  this 
  

   species, 
  as 
  also 
  T. 
  crenata, 
  is 
  united 
  with 
  T. 
  pripnna, 
  Herbst 
  : 
  

   possibly 
  therefore 
  it 
  occurs 
  also 
  on 
  the 
  coasts 
  of 
  the 
  lied 
  Sea, 
  but 
  

   there 
  is 
  nothing 
  to 
  show 
  whether 
  Kossmann 
  had 
  among 
  thq 
  speci- 
  

   mens 
  he 
  refers 
  to 
  T. 
  ■prymna 
  any 
  examples 
  truly 
  referable 
  to 
  

   T. 
  picta, 
  Stimpson.

  A 
  small 
  male 
  from 
  the 
  Seychelles, 
  4-12 
  fms. 
  (No. 
  194), 
  seems 
  to 
  

   be 
  referable 
  to 
  this 
  species 
  ; 
  it 
  has 
  the 
  carapace 
  very 
  prettily 
  

   marked 
  with 
  circular 
  spots 
  of 
  a 
  dusky 
  purplish 
  colour 
  with 
  darker 
  

   borders. 
  Specimens 
  are 
  in 
  the 
  British-Museum 
  collection

  {Rev.

  and 
  Suwarrow

  (li.

  In 
  these 
  specimens, 
  as 
  in 
  the 
  one 
  figured 
  by 
  Dana 
  from 
  the 
  

   Fijis, 
  the 
  purplish 
  markings 
  usually 
  predomiiuite, 
  so 
  as 
  sometimes 
  

   nearly 
  to 
  cover 
  the 
  carapace.

  Kossmann 
  (t.

  p.

  records 
  a 
  variety 
  (albhnamis) 
  from 
  the 
  Bed 
  

   Sea, 
  which 
  is 
  apparently 
  scarcely 
  distinguishable 
  from 
  the 
  typical 
  

   form 
  of 
  the 
  species.

  A 
  specimen 
  obtained 
  at 
  Mahc 
  Island 
  with 
  the 
  preceding 
  species 
  

   is 
  referred 
  here, 
  although 
  with 
  some 
  hesitation. 
  G.

   been 
  hitherto 
  a
