  Noturus

  Swain 
  & 
  Kalb 
  (Proc. 
  U. 
  S. 
  Nat. 
  Mus., 
  1882, 
  639) 
  seems 
  to 
  mo 
  

   identical 
  with 
  Noturus 
  exilis. 
  I 
  regard 
  the 
  latter 
  as 
  distinct 
  from 
  N. 
  insignis. 
  For 
  a 
  

   detailed 
  review 
  of 
  the 
  genus 
  Noturus, 
  see

  r, 
  Tlie 
  species 
  called 
  in 
  the 
  Synopsis 
  Arniurus 
  xantlwcephalus 
  seems 
  to 
  bo 
  not 
  distinct 
  

   from 
  A. 
  melas. 
  Arniurus 
  cragini 
  Gilbert, 
  Bull. 
  Washburn 
  Lab. 
  Nat. 
  Hist., 
  18S4, 
  1,10, 
  

   from 
  Kansas, 
  is 
  identical 
  with 
  Arniurus 
  obesus 
  Gill, 
  which 
  I 
  regard 
  as 
  the 
  original 
  melaa 
  

   of 
  Rafinesque. 
  Arniurus 
  brachy 
  acanthus 
  Cope 
  is 
  probably 
  the 
  same 
  species. 
  The 
  chief 
  

   characters 
  by 
  wbich 
  A. 
  melas 
  is 
  distinguished 
  from 
  A. 
  nebulosus 
  are 
  tbo 
  much 
  shorter 
  

   pectoral 
  spines 
  and 
  sborter 
  anal 
  fin 
  of 
  the 
  former.

  The 
  original 
  Silurus 
  catus 
  L. 
  was 
  certainly 
  not 
  this 
  species, 
  or 
  any 
  other 
  Nortb 
  

   American 
  siluroid. 
  Tbo 
  oldest 
  tenable 
  specilic 
  name 
  for 
  this 
  species 
  is 
  that 
  of 
  nebulo- 
  

   sus 
  Lo 
  Sueur.

  The 
  typo 
  of 
  Pimelodus 
  catulus 
  Girard 
  should 
  be 
  referred 
  to 
  A. 
  nebulosus 
  ratber 
  than 
  

   to^4. 
  melas. 
  It 
  represents 
  a 
  slight 
  variety 
  of 
  A, 
  melas 
  occurring 
  in 
  the 
  lower 
  Mississippi 
  

   Valley 
  and 
  Texas.
