  Remarks. 
  — 
  This 
  is 
  perhaps 
  the 
  largest 
  species 
  of 
  Paludina 
  which 
  

   has 
  yet 
  been 
  observed. 
  It 
  is 
  remarkable 
  for 
  the 
  numerous 
  fine 
  trans- 
  

   verse 
  striae 
  which 
  are 
  subgranose 
  or 
  undulated, 
  and 
  which 
  cover, 
  in 
  some 
  

   specimens, 
  the 
  whole 
  of 
  the 
  whorls. 
  About 
  the 
  middle 
  of 
  the 
  whorls 
  

   there 
  are 
  several 
  larger 
  striae, 
  the 
  largest 
  being 
  always, 
  in 
  the 
  specimens 
  

   examined 
  by 
  me. 
  immediately 
  above 
  the 
  suture. 
  I 
  owe 
  to 
  Dr 
  Bur- 
  

   rough's 
  great 
  kindness 
  the 
  opportunity 
  of 
  describing 
  this 
  species. 
  

   During 
  his 
  late 
  voyage 
  he 
  procured 
  it, 
  with 
  many 
  other 
  fine 
  shells, 
  

   from 
  the 
  vicinity 
  of 
  Manilla, 
  in 
  the 
  island 
  of 
  Luconia.
