  contains 
  an 
  important 
  discussion 
  

   of 
  the 
  fish 
  fauna 
  of 
  Nevada, 
  Oregon, 
  and 
  Idaho, 
  with 
  description 
  of 
  numerous 
  fossil 
  

   forma 
  not 
  long 
  extinct 
  and 
  closely 
  allied 
  to 
  recent 
  Cyprinidce 
  and 
  Catostomidce. 
  

  

  1 
  The 
  two 
  forms 
  of 
  Erimyzon 
  described 
  in 
  the 
  Synopsis 
  as 
  E. 
  sucetta 
  and 
  E. 
  goodei 
  seem 
  

   to 
  ho 
  geographical 
  varieties 
  of 
  one 
  species, 
  southern 
  specimens 
  Laving 
  the 
  scales 
  con- 
  

   siderably 
  larger 
  and 
  more 
  regularly 
  arranged 
  than 
  in 
  northern 
  ones. 
  To 
  the 
  south- 
  

   ern 
  form 
  belong 
  the 
  typical 
  examples 
  of 
  Moxostoma 
  Icennerlyi 
  Girard 
  and 
  Erimyzon 
  

   goodei 
  Jordan. 
  Specimens 
  of 
  this 
  form 
  have 
  been 
  examined 
  by 
  me, 
  from 
  streams 
  of 
  

   South 
  Carolina, 
  Georgia, 
  Florida, 
  Alabama, 
  Louisiana, 
  Illinois, 
  and 
  Texas. 
  From 
  

   Alabama, 
  Louisiana, 
  and 
  Illinois 
  I 
  have 
  seen 
  specimens 
  more 
  or 
  less 
  distinctly 
  inter- 
  

   mediate, 
  while 
  from 
  Virginia 
  to 
  Indian 
  Territory 
  (types 
  M. 
  claviforrnis) 
  and 
  north- 
  

   ward 
  only 
  the 
  small-scaled 
  form 
  occurs. 
  It 
  is 
  probable 
  that 
  the 
  original 
  description 
  

   of 
  Cat. 
  sucetta 
  Lac. 
  belongs 
  to 
  the 
  southern 
  form 
  {Icennerlyi 
  = 
  goodei). 
  The 
  northern 
  

   form 
  may 
  then 
  retaiu 
  Mitchill's 
  name, 
  oblongus.

  I 
  now 
  omit 
  from 
  the 
  list, 
  Moxostoma 
  bucco 
  Cope, 
  based 
  on 
  the 
  young 
  of 
  some 
  species, 
  

   probably 
  of 
  M. 
  aureolum.

  1 
  have 
  recently 
  found 
  the 
  types 
  of 
  Catostomus 
  congestus 
  and 
  Ptychosiomus 
  albidus. 
  

   They 
  belong 
  to 
  the 
  same 
  species, 
  a 
  species 
  shown 
  by 
  the 
  late 
  explorations 
  of 
  Jor- 
  

   dau 
  & 
  Gilbert 
  in 
  Texas, 
  to 
  be 
  very 
  abundant 
  in 
  the 
  waters 
  of 
  that 
  State. 
  The 
  typo 
  

   of 
  P. 
  albidus 
  has 
  44 
  scales 
  in 
  the 
  lateral 
  line 
  instead 
  of 
  56 
  as 
  shown 
  in 
  Girard's 
  figure. 
  

   The 
  specimens 
  from 
  Ash 
  Creek, 
  Arizona, 
  referred 
  with 
  doubt 
  to 
  this 
  species 
  by 
  Copo 
  

   & 
  Yarrow 
  (Lieutenant 
  Wheeler's 
  Expl. 
  Zoology, 
  V. 
  680, 
  1876) 
  belong 
  apparently 
  to 
  M. 
  

   congestum. 
  The 
  following 
  account 
  is 
  taken 
  from 
  specimens 
  taken 
  by 
  us 
  in 
  Lampasas 
  

   River, 
  at 
  Beltou, 
  Tex. 
  : 
  

  

  General 
  form 
  of 
  M. 
  aureolum, 
  rather 
  robust, 
  moderately 
  compressed, 
  the 
  back 
  some- 
  

   what 
  elevated. 
  Head 
  comparatively 
  short, 
  rather 
  broad 
  above 
  and 
  pointed 
  anteriorly 
  ;
