  The 
  type 
  does 
  not 
  seem 
  to 
  be 
  a 
  fully 
  adult 
  individual, 
  the 
  coloring 
  

   of 
  the 
  band 
  on 
  forehead, 
  the 
  under 
  parts 
  and 
  legs 
  are 
  brownish 
  black 
  

   and 
  sooty 
  instead 
  of 
  jet 
  black, 
  appearing 
  to 
  indicate 
  immaturity. 
  The 
  

   type 
  came 
  from 
  Angola. 
  Fortunately 
  there 
  is 
  an 
  adult 
  Lasiopyga 
  

   from 
  Dando, 
  North 
  Angola, 
  which 
  is 
  doubtless 
  the 
  same 
  species 
  as 
  

   pluto, 
  and 
  which 
  presents 
  us 
  with 
  adult 
  pelage. 
  It 
  may 
  be 
  described 
  

   as 
  follows 
  : 
  band 
  on 
  forehead, 
  narrow 
  at 
  ends 
  and 
  broad 
  in 
  the 
  center, 
  

   white 
  with 
  a 
  row 
  of 
  speckled 
  black 
  and 
  white 
  hairs 
  at 
  the 
  base 
  of 
  the 
  

   band 
  in 
  front 
  ; 
  sides 
  of 
  head 
  and 
  throat 
  black 
  speckled 
  with 
  white 
  ; 
  

   top 
  of 
  head 
  and 
  temples 
  black; 
  back 
  of 
  head 
  and 
  neck 
  speckled 
  black 
  

   and 
  white, 
  overlaid 
  by 
  long 
  jet 
  black 
  hairs, 
  these 
  last 
  extending 
  down 
  

   to 
  between 
  the 
  shoulders; 
  upper 
  part 
  of 
  body 
  and 
  flanks 
  profusely 
  

   speckled 
  black 
  and 
  white, 
  the 
  latter 
  here 
  greatly 
  predominating 
  ; 
  inner 
  

   and 
  outer 
  side 
  of 
  arms 
  and 
  legs, 
  hands, 
  feet, 
  and 
  entire 
  under 
  parts 
  

   below 
  throat 
  jet 
  black 
  ; 
  chin 
  and 
  upper 
  part 
  of 
  throat 
  sooty 
  gray 
  ; 
  tail, 
  

   basal 
  half 
  black 
  speckled 
  with 
  white, 
  apical 
  half 
  black. 
  

  

  Mr. 
  Pocock 
  in 
  his 
  review, 
  (1. 
  c.) 
  gives 
  the 
  character 
  to 
  separate 
  

   L. 
  pluto 
  from 
  L. 
  stuhlmanni 
  as 
  the 
  "speckling 
  of 
  the 
  summit 
  of 
  the 
  

   head 
  with 
  the 
  nape 
  and 
  shoulders," 
  but 
  the 
  specimen 
  from 
  Angola, 
  

   which 
  I 
  consider 
  the 
  adult 
  pluto 
  has 
  the 
  summit 
  of 
  the 
  head 
  jet 
  black, 
  

   so 
  it 
  would 
  seem 
  that 
  the 
  speckling 
  on 
  the 
  head 
  was 
  due 
  to 
  immaturity. 
  

   L. 
  pluto's 
  claims 
  for 
  being 
  a 
  distinct 
  species 
  must 
  therefore 
  rest 
  on 
  

   some 
  other 
  differences 
  to 
  separate 
  it 
  from 
  L. 
  stuhlmanni, 
  and 
  these
