  Measurements. 
  Size 
  about 
  same

  nictitans. 
  The 
  skull 
  

   attributed 
  to 
  this 
  type 
  specimen 
  is 
  that 
  of 
  a 
  very 
  young 
  female, 
  and 
  

   evidently 
  never 
  belonged 
  to 
  it. 
  

  

  The 
  type 
  has 
  been 
  in 
  the 
  British 
  Museum 
  Collection 
  since 
  1880, 
  

   was 
  mounted 
  and 
  has 
  been 
  made 
  into 
  a 
  skin. 
  It 
  formerly 
  belonged 
  

   to 
  the 
  La 
  Glaize 
  Collection 
  and 
  bears 
  on 
  the 
  ticket 
  the 
  locality 
  

   "Gaboon." 
  This 
  is 
  so 
  close 
  to 
  the 
  Benito 
  River, 
  for 
  I 
  suppose 
  

   'Gaboon' 
  River 
  is 
  intended, 
  that 
  it 
  is 
  not 
  to 
  be 
  expected 
  there 
  could 
  be 
  

   in 
  the 
  territory 
  two 
  distinct 
  forms. 
  The 
  L. 
  n. 
  laglaizi 
  is 
  most 
  doubt- 
  

   fully 
  separable 
  from 
  L. 
  nictitans.
