  large, 
  and 
  shows 
  how 
  little 
  this 
  part 
  of 
  Africa 
  has 
  

   been 
  worked. 
  No 
  less 
  than 
  six 
  species 
  and 
  subspecies 
  have 
  

   proved 
  to 
  need 
  description 
  out 
  of 
  the 
  small 
  total 
  of 
  fourteen 
  

   represented. 
  

  

  The 
  most 
  interesting 
  form 
  is 
  the 
  new 
  mole-rat, 
  Georychus 
  

   foxij 
  as 
  the 
  only 
  species 
  of 
  the 
  genus 
  previously 
  known 
  in 
  

   West 
  Africa 
  is 
  the 
  widely 
  different 
  G. 
  zechi 
  of 
  Togoland. 
  

  

  The 
  collection 
  is 
  therefore 
  a 
  very 
  valuable 
  accession 
  to 
  the 
  

   National 
  Museum, 
  and 
  one 
  most 
  encouraging 
  for 
  the 
  prospects 
  

   of 
  further 
  work 
  in 
  the 
  Colony.
