  brought 
  home 
  by 
  

   the 
  Alexander-Gosling

  shows 
  the 
  same

   of

  There 
  is 
  a 
  gradual 
  increase 
  in 
  size 
  and 
  facial 
  length 
  in 
  the 
  

   local 
  races 
  of 
  C. 
  dorsalis. 
  The 
  West-Coast 
  forms 
  like 
  C. 
  d. 
  

   dorsalis 
  are 
  small 
  and 
  have 
  a 
  short 
  rostrum, 
  the 
  length 
  

   from 
  orbit 
  to 
  gnathion 
  being 
  generally 
  less 
  than 
  the 
  zygo- 
  

   matic 
  width 
  ; 
  in 
  C. 
  d. 
  castaneus 
  from 
  South 
  Nigeria 
  and 
  the 
  

   Western 
  Cameroons 
  the 
  length 
  of 
  the 
  rostrum 
  is 
  already 
  

   greater 
  than 
  the 
  zygomatic 
  width 
  ; 
  in 
  the 
  races 
  of 
  the 
  Congo 
  

   forest, 
  as 
  typified 
  by 
  orientalis, 
  the 
  skull 
  has 
  the 
  normal 
  

   shape 
  of 
  a 
  Cephalophus, 
  the 
  relation 
  between 
  facial 
  length 
  

   and 
  zygomatic 
  width 
  being 
  not 
  at 
  all 
  so 
  unusual 
  as 
  it 
  is 
  in 
  

   the 
  short-headed 
  typical 
  form.
