  According 
  to 
  Liitken 
  (Vidensk. 
  Meddels. 
  naturh. 
  Foren. 
  Kj0b., 
  1876, 
  92), 
  Cottus 
  

   bicornis 
  Reinhardt 
  is 
  identical 
  with 
  Icelus 
  hamatus 
  Kroyer. 
  It 
  is 
  thought 
  by 
  Liitken 
  

   that 
  Cottus 
  polaris 
  Sabine 
  is 
  probably 
  also 
  the 
  same 
  fish, 
  but 
  if 
  so, 
  the 
  description 
  of 
  

   Sabine 
  is 
  very 
  erroneous. 
  Nos. 
  1053 
  and 
  1083 
  may 
  therefore 
  be 
  erased, 
  and 
  the 
  species 
  

   Icelus 
  hamatus 
  in 
  the 
  Synopsis 
  may 
  stand 
  as 
  Icelus 
  bicornis.

  Icelinus, 
  genus 
  or 
  subgenus 
  nova 
  for 
  Artedius 
  quadriseriatus 
  Lockington, 
  character- 
  

   ized 
  by 
  the 
  peculiar 
  squamation, 
  preopercular 
  armature, 
  and 
  form 
  of 
  the 
  body 
  as 
  

   described 
  in 
  the 
  Synopsis, 
  p. 
  691. 
  (Name 
  a 
  diminutive 
  of 
  Icelus.) 
  

  

  6 
  Artediellus 
  Jordan. 
  

  

  (Genusnova; 
  type 
  Cottus 
  uncinatus 
  Reinhardt.) 
  

  

  This 
  genus 
  or 
  subgenus 
  differs 
  from 
  Icelus 
  proper, 
  apparently 
  its 
  nearest 
  ally, 
  in 
  

   having 
  the 
  skin 
  naked 
  and 
  smooth. 
  Centridermichthys 
  Richardson, 
  an 
  Asiatic 
  genns 
  

   to 
  which 
  this 
  and 
  other 
  American 
  species 
  have 
  been 
  sometimes 
  referred, 
  has 
  the 
  skin 
  

   prickly, 
  and 
  a 
  large 
  slit 
  behind 
  the 
  fourth 
  gill, 
  the 
  gill 
  membranes 
  being 
  fully 
  united 
  

   to 
  the 
  isthmus.

  Artedius.)
