  From

  and 
  Marie 
  Louise 
  come 
  a 
  number 
  of 
  small 
  

   immature 
  specimens 
  of 
  an 
  Actinometra, 
  of 
  the 
  general 
  formula 
  

  

  * 
  It 
  is 
  possible 
  that 
  some 
  elegantly 
  coloured 
  forms 
  from 
  the 
  Seychelles 
  be- 
  

   long 
  to 
  an 
  undescribed 
  species 
  of 
  Ophwpsammiuiii 
  ; 
  it 
  is, 
  liowever, 
  one 
  of 
  wbicli 
  

   I 
  have 
  not 
  seen 
  any 
  examples, 
  and, 
  at 
  present, 
  I 
  find 
  it 
  impossible 
  to 
  come 
  to 
  

   any 
  final 
  conckision 
  as 
  to 
  their 
  generic 
  position 
  or 
  the 
  exact 
  relations 
  of 
  the 
  

   genus 
  Ophiopsammium. 
  

  

  t 
  The 
  single 
  specimen 
  of 
  Ecliinaster 
  purpnrcus 
  from 
  Daros 
  Island 
  has 
  a 
  

   much 
  stouter 
  liabit 
  and 
  stronger 
  less 
  numerous 
  spines 
  than 
  examples 
  from 
  

   more 
  eastern 
  localities 
  ; 
  but 
  at 
  the 
  same 
  time 
  it 
  is 
  by 
  the 
  same 
  points 
  to 
  be 
  

   distinguished 
  from 
  Savigny's 
  figure.
