  The 
  general 
  appearance 
  of 
  this 
  species 
  is 
  that 
  of 
  a 
  reddish 
  monkey 
  

   quite 
  different 
  in 
  coloring 
  from 
  its 
  paler 
  relatives 
  of 
  the 
  L. 
  centralis 
  

   style. 
  It 
  is 
  nearer 
  to 
  the 
  animal 
  from 
  Portuguese 
  East 
  Africa, 
  which 
  

   has 
  been 
  accepted 
  as 
  representing 
  L. 
  rufoviridis, 
  but 
  differs 
  from 
  that 
  

   species 
  in 
  its 
  pinkish 
  buff 
  whiskers, 
  throat 
  and 
  general 
  color 
  of 
  the 
  

   under 
  parts, 
  and 
  in 
  its 
  jet 
  black 
  hands 
  and 
  feet. 
  A 
  number 
  of 
  speci- 
  

   mens 
  from 
  Fort 
  Hall 
  are 
  in 
  the 
  British 
  Museum. 
  

  

  Unfortunately 
  there 
  are 
  no 
  skulls 
  of 
  the 
  L. 
  c. 
  johnstoni 
  specimens, 
  

   so 
  I 
  can 
  make 
  no 
  comparison 
  with 
  them 
  and 
  that 
  of 
  the 
  present 
  species.
