  Agrees 
  ■with 
  P. 
  trivirgatus 
  of 
  Timor 
  ia 
  its 
  black 
  upper 
  tail-coverts, 
  

   which 
  in 
  the 
  type 
  specimens 
  of 
  P. 
  gouldi 
  are 
  grey. 
  

  

  In 
  the 
  'Catalogue 
  of 
  Birds 
  ' 
  (vol. 
  iv. 
  p. 
  419) 
  I 
  united 
  Gould's 
  

   3Ionarc?ia 
  albiventris 
  with 
  Piezorhi/ncJius 
  gouldi, 
  but 
  I 
  now 
  believe 
  

   that 
  I 
  was 
  wrong 
  in 
  doing 
  so. 
  It 
  may 
  be 
  a 
  matter 
  of 
  opinion 
  

   whether 
  the 
  three 
  forms 
  here 
  alluded 
  to 
  are 
  more 
  than 
  local 
  races 
  or 
  

   subspecies 
  ; 
  but 
  it 
  is 
  certain 
  that 
  the 
  white-flanked 
  individuals, 
  P. 
  

   albiventris 
  ( 
  Gould), 
  have 
  the 
  upper 
  tail-coverts 
  blackish, 
  whereas 
  in 
  

   the 
  rufous-flanked 
  birds, 
  P. 
  gouldi 
  (Gray), 
  the 
  tail-coverts 
  are 
  grey.
