  The 
  above 
  specimens 
  agree 
  closely 
  with 
  the 
  original 
  description 
  

   except 
  for 
  color 
  of 
  inner 
  surface 
  of 
  forelimbs, 
  which 
  are 
  "bright 
  rufous 
  

   to 
  the 
  wrists" 
  in 
  the 
  type. 
  Unlike 
  the 
  male, 
  with 
  a 
  broad 
  pale 
  frontal 
  

   region 
  sharply 
  defining 
  the 
  dark 
  brown 
  cap, 
  the 
  female 
  has 
  a 
  dark 
  

   brown 
  frontal 
  diadem 
  continuous 
  with 
  the 
  cap. 
  This 
  is 
  the 
  condition 
  

   in 
  the 
  type 
  specimen, 
  also 
  a 
  female.

  Remarks. 
  — 
  Thomas, 
  in 
  recording 
  the 
  same 
  individuals 
  described 
  

   above, 
  said 
  that 
  they 
  "agree 
  in 
  every 
  detail 
  with 
  the 
  type 
  and 
  confirm 
  

   its 
  distinction 
  as 
  a 
  local 
  form." 
  Certain 
  of 
  the 
  collector's 
  measure- 
  

   ments 
  of 
  the 
  type 
  reproduced 
  in 
  the 
  original 
  description 
  are 
  obviously 
  

   incorrect. 
  Head 
  and 
  body 
  length 
  given 
  as 
  340 
  mm. 
  seems 
  to 
  be 
  too 
  

   short 
  for 
  an 
  old 
  adult 
  with 
  skull 
  length 
  of 
  93.5 
  mm. 
  Tail 
  length 
  of 
  

   390 
  mm. 
  may 
  also 
  be 
  too 
  short 
  though 
  it 
  is 
  not 
  disproportionate 
  to 
  

   the 
  given 
  head 
  and 
  body 
  length. 
  Hind 
  foot 
  length 
  of 
  250 
  mm. 
  is 
  

   nearly 
  twice 
  normal 
  size.
