  Our 
  specimens 
  vary 
  much 
  in 
  form 
  and 
  in 
  coloring. 
  Some 
  are 
  

   almost 
  fiat, 
  but 
  the 
  cup 
  is 
  as 
  deep 
  in 
  such 
  as 
  in 
  the 
  more 
  coni- 
  

   cal 
  shells 
  : 
  such 
  specimens 
  grow 
  on 
  a 
  concave 
  surface. 
  One 
  

   shell, 
  instead 
  of 
  having 
  a 
  subcircular 
  outline, 
  has 
  the 
  outline 
  of 
  

   a 
  very 
  eccentric 
  ellipse. 
  The 
  color 
  of 
  some 
  is 
  nearly 
  white 
  ; 
  of 
  

   others, 
  a 
  deep 
  brown; 
  many 
  are 
  spotted 
  and 
  striped 
  in 
  the 
  

   manner 
  described 
  by 
  Mr. 
  Broderip.
