  Remarks 
  This 
  superb 
  Paludina, 
  which 
  far 
  surpasses 
  in 
  point 
  of 
  

  

  beauty 
  any 
  of 
  our 
  species 
  yet 
  known, 
  I 
  owe 
  to 
  the 
  kindness 
  of 
  Judge 
  

   Tait. 
  Its 
  beautiful 
  double 
  tuberculated 
  cincture 
  at 
  once 
  distinguishes 
  

   it 
  from 
  all 
  described 
  species. 
  Some 
  specimens 
  are 
  furnished 
  with 
  

   dark 
  purple 
  bands 
  which 
  beautifully 
  decorate 
  the 
  interior 
  of 
  the 
  shell, 
  

   and 
  give 
  a 
  dark 
  rich 
  green 
  colour 
  to 
  its 
  fine 
  epidermis. 
  In 
  the 
  others 
  

   these 
  are 
  wanting, 
  and 
  the 
  epidermis 
  then 
  has 
  a 
  clear 
  and 
  more 
  yel- 
  

   low 
  appearance. 
  The 
  sutures 
  being 
  formed 
  immediately 
  over 
  the 
  

   lower 
  row 
  of 
  tubercles, 
  they 
  cause 
  its 
  line 
  to 
  be 
  very 
  irregular 
  ; 
  and 
  

   this 
  row 
  itself 
  is 
  hidden 
  on 
  the 
  upper 
  whorls.

  Philosophical 
  Society,

  SINCE 
  I 
  had 
  the 
  pleasure 
  to 
  present 
  to 
  this 
  Society, 
  nearly 
  a 
  year 
  

   since, 
  a 
  Memoir 
  on 
  the 
  Naiades 
  and 
  some 
  other 
  families, 
  I 
  have 
  had 
  it 
  

   in 
  my 
  power 
  to 
  procure 
  several 
  interesting 
  species, 
  hitherto 
  unnoticed 
  

   by 
  naturalists. 
  In 
  the 
  large 
  collection 
  of 
  rare 
  shells 
  which 
  I 
  procured 
  

   in 
  Europe 
  while 
  there 
  last 
  year, 
  some 
  of 
  these 
  were 
  discovered 
  ; 
  and 
  

   most 
  of 
  them 
  are, 
  perhaps, 
  the 
  only 
  specimens 
  known, 
  being 
  now 
  first 
  

   described. 
  The 
  observations 
  on, 
  and 
  corrections 
  of, 
  Lamarck's 
  Naiades, 
  

   it 
  is 
  hoped, 
  will 
  prove 
  useful 
  to 
  the 
  American 
  conchologist.
