  This 
  species 
  is 
  distinguished 
  by 
  its 
  very 
  dark 
  colouring. 
  It 
  has 
  

   much 
  the 
  same 
  form 
  as 
  the 
  typical 
  A. 
  ovata, 
  but 
  more 
  depressed 
  at 
  

   the 
  sutui'e. 
  It 
  is 
  somewhat 
  similar 
  in 
  appearance 
  to 
  A. 
  paptjracea, 
  

   Spix, 
  from 
  Meobamba.

  I 
  am 
  indebted 
  to 
  Mr. 
  Bryant 
  "Walker, 
  of 
  Detroit, 
  Michigan, 
  for 
  

   this 
  correction. 
  In 
  giving 
  the 
  date 
  of 
  the 
  publication 
  of 
  Say's 
  

   Ampidlaria 
  paludosa 
  as 
  1840, 
  I 
  find 
  I 
  was 
  referring 
  to 
  a 
  reprint, 
  

   the 
  name 
  having 
  been 
  published 
  in 
  1829 
  as 
  a 
  substitute 
  for 
  A. 
  depressa, 
  

   preoccupied 
  by 
  Lamarck 
  for 
  a 
  fossil 
  species. 
  It 
  is 
  not 
  the 
  variety 
  

   named 
  by 
  Hanley 
  Bysoni, 
  but 
  the 
  typical 
  form 
  named 
  by 
  Lea 
  

   Sopetonensis.
