  The 
  hippopotamus 
  of 
  the 
  Lake 
  Chad 
  region 
  is 
  nearly 
  

   allied 
  to 
  //. 
  a. 
  amphibius 
  of 
  the 
  Nile, 
  in 
  which 
  the 
  orbits 
  are 
  

   less 
  projecting 
  ; 
  from 
  H. 
  a. 
  australis 
  of 
  the 
  Cape 
  this 
  race 
  is 
  

   at 
  once 
  distinguished 
  by 
  the 
  much 
  shorter 
  and 
  broader 
  face 
  

   and 
  the 
  orbits 
  being 
  laid 
  forwards.
