  molar; 
  the 
  palate 
  is 
  longer 
  and 
  wider, 
  and 
  the 
  basioccipital 
  much 
  

   shorter 
  and 
  narrower. 
  The 
  difference 
  in 
  the 
  size 
  of 
  this 
  bone 
  in 
  the 
  

   two 
  skulls 
  compared 
  is 
  remarkable. 
  

  

  "This 
  is 
  a 
  rather 
  extraordinary 
  example. 
  It 
  has 
  been 
  in 
  the 
  

   British 
  Museum 
  for 
  a 
  long 
  time, 
  was 
  obtained 
  from 
  Mr. 
  Bartlett 
  and 
  

   is 
  stated 
  to 
  have 
  come 
  from 
  West 
  Africa, 
  no 
  particular 
  locality 
  given. 
  

   Besides 
  the 
  many 
  differences 
  in 
  the 
  coloring 
  of 
  the 
  pelage 
  between 
  this 
  

   specimen 
  and 
  examples 
  of 
  L. 
  cephus, 
  the 
  rufous 
  brow 
  band 
  at 
  once 
  

   removes 
  it 
  from 
  that 
  species, 
  and, 
  seems 
  to 
  point 
  to 
  an 
  affinity 
  to 
  L. 
  

   neglecta 
  and 
  L. 
  brazz^e 
  the 
  only 
  other 
  species 
  possessing 
  this 
  peculiar 
  

   mark, 
  excepting 
  the 
  curious 
  animal 
  I 
  have 
  named 
  L. 
  insolita. 
  It 
  is 
  

   neither 
  so 
  broad 
  as 
  the 
  brow 
  bands 
  of 
  those 
  species, 
  and 
  it 
  is 
  the 
  only 
  

   character 
  these 
  animals 
  have 
  in 
  common, 
  so 
  far 
  as 
  their 
  style 
  of 
  

   coloring 
  is 
  concerned. 
  If 
  there 
  is 
  any 
  relationship 
  between 
  the 
  present 
  

   species 
  and 
  either 
  of 
  the 
  two 
  mentioned 
  it 
  would 
  of 
  course 
  naturally 
  

   be 
  with 
  L. 
  brazz^e, 
  from 
  the 
  Congo, 
  as 
  L. 
  neglecta, 
  the 
  relative 
  of 
  

   L. 
  brazz^e, 
  comes 
  from 
  the 
  White 
  Nile 
  region."
