  This 
  name 
  may 
  be 
  provisionally 
  retained 
  for 
  the 
  teeth 
  of 
  

   Saurichthys 
  from 
  the 
  Bhaetic 
  horizons 
  of 
  N.W. 
  Europe. 
  They 
  

   indicate 
  a 
  species 
  with 
  a 
  robust 
  dentition, 
  the 
  more 
  typical 
  teeth 
  

   only 
  differing 
  from 
  those 
  named 
  S. 
  mougeoti 
  in 
  the 
  relatively 
  shorter 
  

   basal 
  portion 
  and 
  the 
  prominence 
  of 
  the 
  inferior 
  rim 
  of 
  the 
  apical 
  

   gano-dentine. 
  The 
  extreme 
  variations 
  in 
  the 
  form 
  of 
  the 
  teeth 
  are 
  

   pointed 
  out 
  by 
  Quenstedt 
  ; 
  and 
  S. 
  longidens 
  is 
  proved 
  to 
  be 
  a 
  

   synonym 
  of 
  S. 
  acuminatus 
  by 
  an 
  imperfect 
  maxilla 
  from 
  Aust
