  The 
  type 
  of 
  Catostornus 
  oernardini 
  is 
  closely 
  related 
  to 
  C. 
  occidentalis, 
  differing 
  

   chiefly 
  in 
  the 
  less 
  conic 
  form 
  of 
  the 
  head 
  and 
  in 
  the 
  larger 
  lower 
  fins. 
  Scales 
  much 
  

   crowded 
  forwards 
  ; 
  31 
  before 
  the 
  dorsal 
  (40 
  in 
  C. 
  occidentalis), 
  75 
  in 
  the 
  lateral 
  line. 
  

   Fontanello 
  large 
  ; 
  lips 
  broad, 
  without 
  cartilaginous 
  sheath, 
  formed 
  as 
  in 
  C. 
  occidentalis, 
  

   the 
  lower 
  deeply 
  incised 
  ; 
  fins 
  high, 
  the 
  dorsal 
  longer 
  than 
  high, 
  with 
  12 
  rays 
  ; 
  caudal 
  

   lobes 
  equal 
  ; 
  head 
  4 
  J- 
  in 
  length. 
  

  

  • 
  Catostornus 
  insignia 
  (typo 
  lately 
  found) 
  is 
  closely 
  related 
  to 
  C. 
  teres, 
  differing 
  chiefly 
  

   in 
  the 
  broader 
  upper 
  lip, 
  which 
  has 
  several 
  rows 
  of 
  tubercles 
  upon 
  it. 
  Fontanello 
  

   rather 
  small 
  ; 
  no 
  cartilaginous 
  sheath 
  on 
  lower 
  lips 
  ; 
  scales 
  considerably 
  crowded 
  

   anteriorly, 
  much 
  more 
  so 
  than 
  in 
  C. 
  clarlci; 
  27 
  scales 
  before 
  dorsal;

  Called 
  in 
  the 
  text, 
  Catostornus 
  commersoni. 
  Although 
  the 
  Cyprinus 
  commersoni 
  of 
  

   Laedpede 
  is 
  probably 
  a 
  sucker 
  and 
  may 
  be 
  this 
  species, 
  there 
  is 
  no 
  certainty 
  in 
  so 
  

   identifying 
  it, 
  the 
  description 
  being 
  very 
  imperfect 
  and 
  the 
  type 
  said 
  to 
  have 
  been 
  

   observed 
  by 
  Commerson 
  in 
  tho 
  East 
  Indies; 
  a 
  statement 
  apparently 
  derived 
  from 
  a 
  

   confusion 
  of 
  manuscripts 
  of 
  Commerson 
  with 
  those 
  of 
  Bosc. 
  We 
  think 
  it 
  better 
  to 
  

   retain 
  for 
  this 
  species 
  the 
  later 
  name 
  of 
  teres, 
  concerning 
  which 
  no 
  doubt 
  exists. 
  To 
  

   this 
  species 
  apparently 
  should 
  bo 
  referred 
  the 
  small 
  "Juno 
  sucker" 
  of 
  the 
  Adiron- 
  

   dacks, 
  described 
  by 
  Mather 
  as 
  Catostornus 
  utawana. 
  Olivaceous,

  (Mather.) 
  Apparently 
  a 
  mountain 
  race 
  of 
  C. 
  teres.

  "This 
  small 
  lish 
  I 
  was 
  at 
  first 
  disposed 
  to 
  consider 
  as 
  a 
  dwarfed 
  mountain 
  form 
  of 
  

   C. 
  commersoni, 
  but 
  tho 
  fact 
  that 
  tho 
  latter 
  fish 
  is 
  found 
  in 
  waters 
  inhabited 
  by 
  this 
  

   species, 
  and 
  while 
  it 
  grows 
  to 
  a 
  length 
  of 
  12 
  or 
  more 
  inches 
  there, 
  this 
  little 
  sucker 
  

   barely 
  reaches 
  five. 
  Added 
  to 
  this 
  the 
  fact 
  that 
  the 
  larger 
  species 
  had 
  finished 
  spawn- 
  

   ing 
  in 
  the 
  inlets 
  in 
  May, 
  while 
  this 
  lish 
  was 
  found 
  in 
  masses 
  in 
  the 
  swift 
  mountain 
  

   streams 
  which 
  tumble 
  rapidly 
  over 
  rocks 
  in 
  tho 
  latter 
  part 
  of 
  June, 
  depositing 
  their 
  

   eggs, 
  thereby 
  showing 
  that 
  they 
  are 
  adult 
  fish."

  In 
  viow 
  of 
  the 
  peculiar 
  form 
  of 
  the 
  cranium 
  in 
  Catostornus 
  nigricans, 
  contrasting 
  

   with 
  that 
  seen 
  in 
  all 
  the 
  other 
  Catostominw, 
  it 
  is 
  probably 
  well 
  to 
  regard 
  it 
  as 
  tho 
  typo 
  

   of 
  a 
  distinct 
  genus, 
  Hypcntclium 
  Rafinesque.
