  excluding 
  anterior 
  margin, 
  ochraceous 
  ; 
  body 
  and 
  legs 
  

   fuscous, 
  the 
  abdominal 
  segmental 
  margins 
  above 
  olivaceous. 
  

   Tegmina 
  olivaceous 
  brown, 
  the 
  venation 
  and 
  reticulations 
  

   olivaceous, 
  excepting 
  on

  area, 
  where 
  they 
  are 
  ochra- 
  

   ceous, 
  and 
  ornamented 
  with 
  a 
  number 
  of 
  small 
  ochraceous 
  

   rounded 
  spots, 
  situate 
  in 
  more 
  or 
  less 
  irregular 
  transverse 
  

   series, 
  each 
  containing 
  about 
  four 
  spots, 
  those 
  on 
  apical 
  area 
  

   smallest 
  ; 
  wings 
  bright 
  dark 
  blue, 
  the 
  apical

  broadly 
  black, 
  this 
  dark

  inwardly 
  deeply 
  

   sinuate. 
  Cephalic

  This 
  species 
  is 
  allied 
  to 
  F. 
  Delessertii, 
  Gue*r., 
  from 
  which 
  it 
  

   differs 
  by 
  the 
  paler 
  colour, 
  different 
  arrangement, 
  and 
  smaller 
  

   size 
  of 
  the 
  spots 
  on 
  the 
  tegmina, 
  the 
  deeply 
  sinuate 
  internal 
  

   margin 
  of 
  the 
  black 
  area 
  of 
  the 
  wings, 
  but 
  chiefly 
  by 
  the 
  

   shape 
  of 
  the 
  cephalic 
  process, 
  which 
  is 
  widened 
  and 
  flattened 
  

   at 
  apex.

  Note 
  on 
  a 
  remarkably 
  large 
  Specimen 
  qf 
  Jjiridia. 
  from 
  

   the 
  Island 
  of 
  Mauritius. 
  By 
  Prof. 
  F. 
  JEFFREY 
  Bell, 
  M.A. 
  

  

  The 
  Trustees 
  of 
  the 
  British 
  Museum 
  have 
  recently 
  purchased 
  

   from 
  M. 
  de 
  llobillard, 
  the 
  well-known 
  collector 
  in 
  the 
  island 
  

   of 
  Mauritius, 
  two 
  large 
  specimens 
  of 
  Luidia 
  Savignii. 
  Both 
  

   of 
  these 
  have 
  nine 
  arms, 
  and 
  the 
  larger 
  specimen 
  is 
  remark- 
  

   able 
  for 
  having 
  all 
  the 
  arms 
  comj)lete, 
  and 
  none 
  of 
  them 
  bear 
  

   any 
  mark 
  of 
  injury 
  or 
  repair. 
  Throughout 
  its 
  life, 
  therefore, 
  

   the 
  creature 
  was 
  able 
  to 
  give 
  its 
  sole 
  attention 
  to 
  its 
  growth, 
  

   and 
  it 
  succeeded 
  in 
  developing 
  a 
  disk 
  of 
  95 
  millim. 
  in 
  dia- 
  

   meter 
  and 
  nine 
  perfect 
  arms, 
  of 
  which 
  the 
  longest 
  measures 
  

   370 
  millim. 
  and 
  the 
  shortest 
  350 
  millim. 
  This 
  specimen 
  is 
  

   therefore 
  more 
  than 
  twice 
  as 
  large 
  as 
  M. 
  de 
  Loriol's 
  " 
  deux 
  

   individus 
  de 
  grande 
  taille," 
  whose 
  " 
  diametre 
  total 
  atteint 
  

   320 
  mm." 
  It 
  is, 
  1 
  think, 
  well 
  to 
  put 
  on 
  record 
  the 
  dimen- 
  

   sions 
  of 
  what 
  is, 
  1 
  fancy, 
  the 
  as 
  yet 
  largest 
  known 
  Asterid 
  ;
