  In

  description

  ' 
  one 
  or 
  

   two 
  important 
  characters 
  are 
  not 
  noticed. 
  The 
  dorsal 
  surface 
  of 
  

   the 
  shell 
  towards 
  both 
  ends 
  is 
  very 
  prettily 
  sculptured 
  in 
  an 
  

   oblique 
  direction 
  with 
  fine 
  wavy 
  strife, 
  as 
  indicated 
  in 
  the 
  figure 
  

   in 
  the 
  above 
  work, 
  the 
  waviness 
  being 
  due 
  to 
  the 
  fine 
  transverse 
  

   lines 
  of 
  growth. 
  The 
  colour 
  is 
  white, 
  more 
  or 
  less 
  transparent.
