  abundant. 
  

  

  In 
  some 
  the 
  warts 
  are 
  obsolete 
  near 
  the 
  base, 
  owing 
  to 
  the 
  animal 
  

   having 
  lived 
  in 
  a 
  narrow 
  crack 
  in 
  the 
  rocks. 
  There 
  is 
  also 
  a 
  variety 
  in 
  

   which 
  the 
  tentacles 
  are 
  purplish 
  grey, 
  and 
  the 
  disc 
  even 
  is 
  sometimes 
  the 
  

   same 
  colour.
