  1 
  Professor 
  Gilbert 
  thinks 
  that 
  this 
  species 
  may 
  be 
  the 
  original 
  Moxostoma 
  anisurum 
  

   of 
  Rafinesque. 
  

  

  -The 
  types 
  of 
  Campostoma 
  ornatum 
  have 
  73 
  scales 
  in 
  the 
  lateral 
  line. 
  Those 
  of 
  C. 
  

   nasutum 
  agree 
  in 
  all 
  respects 
  with 
  the 
  ordinary 
  C. 
  anomalum.

  The 
  types 
  of 
  Campostoma 
  formosulum 
  have 
  46 
  scales

  Hue.

  Chrosomus

  a

  species,

  I 
  have
