  Late 
  in 
  the 
  "eighties" 
  General 
  Dudley 
  A- 
  Averj- 
  sent 
  sev- 
  

   eral 
  other 
  bones 
  to 
  the 
  Smithsonian 
  Institution 
  ; 
  one 
  of 
  which 
  

   was 
  identified 
  as 
  the 
  claw 
  of 
  a 
  M 
  eg 
  atony 
  x. 
  

  

  Probably 
  the 
  largest 
  collection 
  which 
  has 
  ^^et 
  been 
  made 
  at 
  

   this 
  locality 
  was 
  by 
  Dr. 
  Joseph 
  F. 
  Joor, 
  of 
  New 
  Orleans, 
  for 
  

   Tulane 
  University, 
  in 
  1890.* 
  These 
  were 
  submitted 
  to 
  Prof. 
  E. 
  

   D. 
  Cope. 
  In 
  his 
  report 
  he 
  figures 
  and 
  describes 
  two 
  new 
  species 
  

   of. 
  Mylodon 
  and 
  considers 
  that 
  the 
  teeth 
  identified 
  by 
  Leidy 
  as 
  

   Eqiius 
  major 
  T>QK3iy 
  really 
  represent 
  a 
  new 
  speciesf. 
  The 
  species 
  

   determened 
  by 
  him 
  are 
  : 
  

  

  Mastodo?i 
  sp. 
  Mylodon 
  sulcidens

  To 
  this 
  list 
  Dr. 
  Joor 
  adds 
  doubtfully 
  the 
  remains 
  of 
  2in 
  Elephas. 
  

   The 
  bone 
  bed 
  is 
  a 
  fairly 
  rich 
  one 
  and 
  may 
  be 
  expected 
  to 
  yield 
  

   some 
  good 
  material 
  to 
  the 
  careful 
  worker.
