  In 
  his 
  brief 
  

   notes 
  Dixon 
  erroneously 
  refers 
  to 
  the 
  ventral 
  border 
  of 
  

   the 
  fish 
  as 
  " 
  the 
  nape 
  of 
  the 
  neck 
  ; 
  " 
  and 
  the 
  vacuities 
  

   shown 
  in 
  the 
  splenial 
  bone 
  may 
  certainly 
  be 
  regarded 
  as 
  

   accidental. 
  They 
  are 
  not 
  observable 
  in 
  the 
  right 
  splenial, 
  

   and 
  if 
  the 
  drawing 
  be 
  not 
  " 
  restored 
  " 
  the 
  last-named 
  bone 
  

   must 
  have 
  been 
  broken 
  since 
  it 
  left 
  the 
  artist. 
  There 
  is, 
  

   however, 
  apparently 
  much 
  " 
  restoration 
  " 
  in 
  the 
  figure 
  of 
  

   the 
  left 
  splenial, 
  and 
  it 
  is 
  thus 
  probable 
  that 
  no 
  accident 
  

   has 
  happened 
  since 
  the 
  specimen 
  was 
  originally 
  studied.
