  All 
  that 
  were 
  forwarded 
  were 
  small 
  specimens, 
  clean 
  and 
  

   free 
  from 
  nullipore 
  and 
  other 
  growths, 
  consequently 
  charac- 
  

   teristically 
  marked 
  and 
  coloured. 
  One 
  example, 
  with 
  

   noduled 
  ribs, 
  came 
  from 
  " 
  extreme 
  low-water 
  mark," 
  being 
  

   found 
  there 
  in 
  company 
  with 
  Yoldia

  The

  of

  beautiful

  is 
  most 
  delicately 
  squa- 
  

   mose, 
  the 
  scales 
  imbricating. 
  Within, 
  a 
  resemblance 
  to 
  

   P. 
  cenea 
  is 
  seen, 
  and 
  it 
  is 
  probable, 
  wiien 
  a 
  larger 
  series 
  of 
  

   this 
  have 
  been 
  gathered, 
  that 
  intermediates 
  will

  This 
  species 
  seems 
  quite 
  distinct 
  from 
  N. 
  ci/mhularia, 
  

   Lamk., 
  with 
  which 
  it 
  is 
  generally

  is

   prevailing

  Falklands.
