  The 
  discovery 
  of 
  E. 
  jacksoni 
  in 
  West 
  Africa 
  is 
  somewhat 
  

   of 
  a 
  surprise, 
  but 
  I 
  can 
  find 
  no 
  character 
  of 
  importance 
  to 
  

   distinguish 
  the 
  Nigerian 
  form 
  from 
  that 
  inhabiting 
  Uganda, 
  

   some 
  1700 
  miles 
  distant. 
  The 
  paler 
  colour 
  is 
  a 
  natural 
  result 
  

   of 
  the 
  more 
  desert 
  conditions 
  obtaining 
  in 
  Nigeria.
