  and 
  the 
  tail 
  has 
  no 
  tuft 
  like 
  that 
  of 
  L. 
  t. 
  budgetti 
  From 
  L. 
  tantalus 
  

   it 
  differs 
  in 
  cranial 
  characters 
  ; 
  when 
  two 
  old 
  male 
  skulls 
  are 
  compared, 
  

   that 
  of 
  the 
  present 
  race 
  is 
  seen 
  to 
  be 
  much 
  larger 
  in 
  every 
  way 
  ; 
  wider 
  

   orbits 
  and 
  braincase, 
  but 
  narrower 
  rostrum; 
  intertemporal 
  width 
  

   greater; 
  nasals 
  much 
  longer; 
  zygomatic 
  width 
  greater; 
  palate 
  longer; 
  

   tooth 
  rows 
  of 
  both 
  jaws 
  longer 
  by 
  the 
  width 
  of 
  first 
  premolar; 
  and 
  

   bullae 
  very 
  much 
  longer 
  and 
  more 
  elevated. 
  In 
  fact 
  the 
  cranial 
  char- 
  

   acters 
  are 
  so 
  different 
  it 
  is 
  hardly 
  worth 
  while 
  to 
  compare 
  the 
  skulls. 
  

   The 
  upper 
  parts 
  like 
  those 
  of 
  L. 
  t. 
  budgetti 
  are 
  much 
  darker 
  than 
  L. 
  

  

  TANTALUS. 
  

  

  The 
  unique 
  type

  British 
  Museum,

   by 
  Mr. 
  Boyd 
  Alexander 
  at 
  Bambara 
  on 
  the 
  Welle 
  River, 
  Central 
  

   Africa.
