  Genus 
  GORDONIA,

  Newton. 
  

   Gordonia 
  is 
  closely 
  allied 
  to 
  Dicynodon, 
  in 
  having 
  the 
  jaws 
  edentulous 
  

   with 
  the 
  exception 
  of 
  two 
  pointed 
  tusks, 
  one 
  in 
  the 
  maxilla 
  of 
  each 
  

   side, 
  and 
  growing 
  from 
  permanent 
  pulps, 
  but 
  is 
  specially 
  

   characterised 
  by 
  the 
  presence 
  of 
  two 
  post-temporal 
  fossae 
  on 
  each 
  

   side 
  of 
  the 
  occiput, 
  and 
  the 
  comparative 
  slenderness 
  of 
  all 
  the 
  bones 
  

   of 
  the 
  skull.
