  I 
  may 
  supplement 
  Dr. 
  Gadow's 
  description 
  of 
  this 
  species 
  by 
  re- 
  

   marking 
  that 
  there 
  are 
  two 
  distinct 
  shades 
  of 
  colour 
  observable 
  in 
  

   a 
  series 
  of 
  the 
  present 
  species, 
  the 
  birds 
  from 
  Port 
  Darwin 
  and 
  

   " 
  Northern 
  Territory 
  " 
  (ex 
  Gould 
  Coll.) 
  being 
  more 
  mouse-coloured, 
  

   and 
  this 
  is 
  the 
  form 
  which 
  is 
  seen 
  in 
  South-eastern 
  New 
  Guinea. 
  

   The 
  specimens 
  from 
  Queensland, 
  Cape 
  York, 
  and 
  the 
  islands 
  of 
  Torres 
  

   Straits 
  are 
  browner, 
  sometimes 
  inclining 
  to 
  rusty 
  brown. 
  Another 
  

   character 
  which 
  Dr. 
  Gadow 
  omits 
  to 
  mention 
  is 
  the 
  blackish 
  shade 
  

   in 
  the 
  centre 
  of 
  the 
  throat 
  ; 
  it 
  is 
  apparentl}' 
  a 
  mark 
  of 
  an 
  adult 
  

   bird, 
  and 
  is 
  not 
  confined 
  to 
  one 
  sex, 
  but 
  appears 
  to 
  be 
  equally- 
  

   distinct 
  in 
  the 
  female.

  This 
  species 
  is 
  very 
  rarely 
  seen 
  in 
  collections, 
  and 
  was 
  for 
  a 
  long 
  

   time 
  known 
  only 
  from 
  the 
  figure 
  in 
  the 
  ' 
  Voyage 
  au 
  Pole 
  Sud.' 
  It 
  

   was 
  originally 
  described 
  from 
  ^^'alTior 
  Island 
  in 
  Torres 
  Straits, 
  and 
  

   appears 
  to 
  be 
  a 
  recognizable 
  species.
