  The 
  base 
  of 
  the 
  pyramid 
  is 
  octangular 
  in 
  so 
  far 
  that 
  in 
  the 
  

   inferior 
  third 
  two 
  edges 
  are 
  attached 
  to 
  each 
  of 
  the 
  four 
  

   widely 
  projecting 
  angles, 
  and 
  these, 
  running 
  downwards 
  

   obliquely, 
  meet 
  together 
  in 
  four 
  inferior 
  angles 
  which 
  alternate 
  

   with 
  the 
  four 
  upper 
  ones. 
  The 
  large, 
  fusiform, 
  centrally 
  

   placed 
  oil-receptacle

  Halopyramis 
  adamantina 
  is 
  one 
  of 
  the 
  most 
  remarkable 
  

   Canarian 
  forms, 
  not 
  only 
  on 
  account 
  of 
  its 
  peculiar 
  form, 
  

   perfect 
  transparency, 
  and 
  comparatively 
  large 
  size 
  (the 
  calyx 
  

   reaches 
  a 
  height 
  and 
  breadth 
  of 
  15 
  millim.), 
  but 
  also 
  on 
  

   account 
  of 
  the 
  abbreviation 
  of 
  the 
  stem.

  never 
  saw
