  "Jay" 
  (Letson). 
  This 
  citation 
  is 
  an 
  

   error 
  ou 
  the 
  part 
  of 
  the 
  author 
  of 
  the 
  "Check 
  List". 
  The 
  reference 
  

   <;'iven 
  is 
  to 
  Jay's 
  Catalogue 
  of 
  1852, 
  p. 
  69. 
  There 
  is 
  no 
  reference 
  to 
  

   this 
  species 
  on 
  p. 
  69 
  and 
  no 
  citation 
  of 
  it 
  from 
  Lake

   Alasmidonta 
  ynarginata, 
  Say, 
  from 
  Lake 
  Erie, 
  is, 
  however, 
  listed 
  on 
  

   p. 
  69, 
  so 
  that 
  the 
  error 
  is, 
  no 
  doubt, 
  one 
  of 
  transcription.

  Mr. 
  Hinkley 
  in 
  a 
  recent 
  

   letter 
  informs 
  me 
  that 
  the 
  citation 
  was 
  an 
  error, 
  that 
  the 
  species 
  was 
  

   really 
  mojiodorita,

  lliver 
  (Baker). 
  Mr. 
  Baker 
  informs 
  me 
  that 
  this 
  citation 
  is 
  

   based 
  on 
  an 
  undoubted 
  specimen 
  of 
  M. 
  margaritifera, 
  so 
  labelled, 
  in 
  

   the 
  Calkin 
  collection 
  now 
  in 
  the 
  Museum 
  of 
  the 
  Chicago 
  Academy 
  

   of 
  Sciences 
  ; 
  that 
  it 
  has 
  never 
  been 
  found 
  in 
  that 
  region 
  by 
  any 
  other 
  

   collector; 
  that 
  "a 
  number 
  of 
  Calkin's 
  shells 
  are 
  inaccurate 
  as 
  to 
  

   locality, 
  and 
  it 
  is 
  probably 
  another 
  case 
  of 
  the 
  mixing 
  of 
  shells". 
  

   I 
  have 
  no 
  doubt 
  but 
  that 
  this 
  is 
  correct, 
  as 
  I 
  have 
  in 
  my 
  own 
  

   collection 
  a 
  specimen 
  of 
  this 
  species 
  from 
  the 
  collection 
  of 
  the 
  lute 
  

   J. 
  M. 
  Delaney, 
  JSTew 
  York, 
  which 
  is 
  labelled 
  " 
  Ohio 
  Iliver, 
  

   Trumbull, 
  Ohio". 
  This 
  place 
  is 
  in 
  Ashtabula 
  County, 
  a 
  few 
  miles 
  

   south 
  of 
  Lake 
  Erie 
  and 
  in 
  the 
  St. 
  Lawrence 
  drainage, 
  and 
  many 
  miles 
  

   from 
  the 
  Ohio 
  Biver. 
  The 
  specimen 
  is 
  a 
  large 
  one, 
  and 
  very 
  similar 
  

   to 
  the 
  large 
  form 
  from 
  the 
  Winooski 
  River, 
  Vt. 
  The 
  locality 
  is 
  given 
  

   on 
  the 
  label 
  as 
  an 
  impossible 
  one, 
  and 
  there 
  can 
  be 
  no 
  question 
  but 
  

   this 
  again 
  is 
  a 
  " 
  case 
  of 
  mixing 
  shells".
