  Remarks. 
  — 
  The 
  genus 
  Aphrodite 
  is 
  proposed 
  for 
  a 
  single 
  species 
  

   which 
  I 
  am 
  unable 
  to 
  place 
  with 
  any 
  established 
  genus. 
  I 
  suspect 
  it 
  

   to 
  be 
  an 
  estuary 
  shell, 
  and 
  should 
  it 
  prove 
  so, 
  its 
  proper 
  place 
  will 
  be 
  

   after 
  the 
  genus 
  Cyrena. 
  The 
  lateral 
  teeth 
  are 
  placed 
  somewhat 
  like 
  

   those 
  in 
  that 
  genus, 
  but 
  the 
  epidermis 
  and 
  substance 
  of 
  the 
  shell 
  differ 
  

   entirely, 
  being 
  more 
  like 
  the 
  genus 
  Mactra.
