  Interesting, 
  as 
  the 
  first 
  non-marine 
  Pelecjpod 
  recorded 
  

   from 
  these 
  islands. 
  Its 
  nearest 
  congeners, 
  perhaps, 
  are 
  

   S. 
  novcezelandice, 
  Desh., 
  and 
  S. 
  ovale, 
  Stimps. 
  There 
  

   appear 
  two 
  forms, 
  one 
  slightly 
  smaller 
  and 
  more 
  oblique. 
  

   We 
  name 
  it 
  specifically 
  in 
  honour 
  of 
  its 
  discoverers, 
  Mr. 
  and 
  

   Mrs. 
  Rupert 
  Vallentin, 
  whose 
  researches, 
  both 
  botanical, 
  

   zoological, 
  and 
  biological, 
  have 
  proved 
  o£ 
  such 
  lasting 
  service 
  

   to 
  the 
  students 
  of

  productions

  The

  of 
  this 
  species, 
  hardly 
  to

  is

  We 
  consider 
  its 
  presence 
  in 
  the 
  West 
  Falklands 
  

   must 
  be 
  owing 
  to 
  adventitious 
  circumstances.

  We 
  are 
  obliged 
  to 
  Mr. 
  II. 
  B. 
  Preston, 
  one 
  of 
  tlie 
  authors, 
  

   for 
  the 
  identification 
  of 
  this 
  very 
  interesting 
  species, 
  which 
  

   is, 
  apparently, 
  being 
  found 
  to 
  be 
  generally 
  distributed 
  around 
  

   the 
  Falkland 
  group. 
  Mr. 
  Jukes-Browne 
  has 
  also 
  kindly 
  

   favoured 
  us 
  with 
  good 
  specimens.
