  The 
  type 
  is 
  a 
  young 
  animal 
  ; 
  it 
  is 
  difficult 
  to 
  say 
  how 
  youthful, 
  as 
  

   the 
  skull, 
  unfortunately, 
  could 
  not 
  be 
  found. 
  The 
  hair 
  on 
  forehead 
  is 
  

   erect 
  on 
  each 
  side 
  like 
  horns, 
  far 
  above 
  the 
  rest 
  on 
  the 
  head 
  and 
  is
