  Glyptolepis 
  approaches 
  Holoptychius 
  so 
  closely 
  that 
  it 
  has 
  been 
  

   reduced 
  by 
  Mr.

  to 
  the

  a

   Its 
  rounded 
  scales 
  misled 
  Agassiz 
  into 
  placing 
  this 
  species 
  with 
  

   Glyptolepis. 
  It 
  is 
  undoubtedly 
  the 
  same 
  as 
  M 
  'Coy's 
  Gyroptychius 
  

   angustus 
  from 
  Orkney,

   The

  was 
  first 
  devised 
  by 
  Valenciennes 
  

   for 
  a

  identity 
  of 
  which 
  is,
