  Compared 
  with 
  L. 
  stairsi, 
  the 
  type 
  of 
  L. 
  s. 
  mossambicus 
  is 
  a 
  very 
  

   much 
  older 
  animal, 
  and 
  a 
  male. 
  It 
  is 
  an 
  open 
  question 
  whether 
  L. 
  

   stairsi 
  male, 
  equally 
  adult, 
  would 
  not 
  change 
  the 
  coloring 
  as 
  regards 
  

   the 
  speckling 
  on 
  back, 
  and 
  color 
  of 
  the 
  speckling 
  of 
  thighs, 
  which 
  

   comprise 
  the 
  principal 
  differences. 
  

  

  The 
  type 
  of 
  L. 
  stairsi 
  is 
  a 
  baby, 
  and 
  some 
  of 
  its 
  ha^r, 
  like 
  that 
  on 
  

   the 
  tail, 
  is 
  little 
  better 
  than 
  down. 
  It 
  will 
  be 
  necessary 
  to 
  have 
  old 
  

   adults 
  of 
  both 
  forms 
  to 
  compare, 
  before 
  it 
  can 
  be 
  definitely 
  determined 
  

   that 
  they 
  are 
  distinct.
