  Remarks. 
  — 
  On 
  my 
  way 
  to 
  Quebec, 
  in 
  the 
  summer 
  of 
  1829, 
  1 
  spent 
  

   a 
  few 
  minutes 
  on 
  the 
  shore 
  of 
  lake 
  Champlain, 
  nearly 
  opposite 
  to 
  fort 
  

   Ticonderoga, 
  waiting 
  for 
  the 
  steamboat. 
  These 
  minutes 
  were 
  im- 
  

   proved 
  in 
  the 
  search 
  of 
  the 
  shells 
  near 
  the 
  edge 
  of 
  the 
  water. 
  Among 
  

   others 
  hastily 
  seized, 
  was 
  a 
  single 
  individual 
  of 
  the 
  present 
  species, 
  

   which, 
  though 
  an 
  alive 
  specimen, 
  was 
  much 
  decorticated. 
  Unwilling 
  

   to 
  describe 
  it 
  as 
  a 
  new 
  species, 
  without 
  better 
  individuals 
  for 
  examina- 
  

   tion, 
  I 
  have 
  endeavoured 
  in 
  vain 
  to 
  procure 
  them 
  until 
  the 
  present 
  

   time. 
  I 
  owe 
  to 
  the 
  kindness 
  of 
  professor 
  Benedict 
  a 
  suite 
  of 
  different 
  

   ages 
  which 
  verify 
  my 
  previous 
  impression, 
  and 
  to 
  him 
  I 
  dedicate 
  the 
  

   species. 
  In 
  outline 
  (except 
  the 
  wings) 
  it 
  resembles 
  the 
  Symphynota 
  

   bi-alata 
  (nobis). 
  It 
  is 
  not, 
  however, 
  so 
  large 
  or 
  so 
  thick 
  a 
  shell, 
  and 
  

   has 
  neither 
  tooth 
  nor 
  undulations.
