﻿YELLOW-NECKED 
  KOKLASS 
  PHEASANT

  mottling 
  on 
  the 
  outer 
  web, 
  until 
  the 
  outer 
  secondaries 
  and 
  primaries 
  are 
  plain 
  dark 
  

   brown 
  except 
  for 
  a 
  clean-cut 
  margin 
  of 
  pale 
  buff. 
  

  

  The 
  longer 
  three 
  or 
  four 
  pairs 
  of 
  upper 
  tail-coverts 
  and 
  the 
  central 
  pair 
  of 
  rectrices 
  

   show 
  a 
  new 
  type 
  of 
  pattern. 
  The 
  large 
  centre 
  is 
  clear, 
  pale, 
  greyish 
  white. 
  This 
  is 
  

   bordered 
  by 
  the 
  two 
  black 
  lines, 
  which 
  are 
  almost 
  obscured, 
  their 
  greater 
  area 
  being 
  

   taken 
  up 
  by 
  dull 
  chestnut, 
  which 
  pales 
  into 
  light 
  olive 
  at 
  the 
  tip. 
  

  

  All 
  the 
  remaining 
  tail-feathers 
  show 
  broad 
  white 
  tips, 
  succeeded 
  by 
  a 
  broad 
  area 
  of 
  

   black. 
  Most 
  of 
  the 
  remaining 
  portion 
  of 
  the 
  feathers 
  is 
  pale 
  grey, 
  crossed 
  half-way 
  by 
  

   an 
  irregular 
  black 
  bar, 
  the 
  grey 
  above 
  this 
  being 
  also 
  bordered 
  with 
  black. 
  The 
  feathers 
  

   are 
  opaque, 
  the 
  pale 
  grey 
  appearing 
  below 
  as 
  dull 
  brown, 
  barely 
  distinct 
  from 
  the 
  

   black. 
  

  

  In 
  several 
  specimens 
  from 
  Szechuan, 
  the 
  tail-feathers 
  vary 
  strongly 
  in 
  the 
  direction 
  

   oi.tneyeri, 
  and 
  hence 
  toward 
  macrolopha. 
  

  

  The 
  under 
  tail-coverts 
  are 
  richly 
  tricoloured, 
  bright 
  chestnut 
  basally, 
  succeeded 
  by 
  

   a 
  black 
  bar 
  and 
  a 
  large 
  round 
  terminal 
  spot 
  of 
  white. 
  Iris 
  brown 
  ; 
  bill 
  black 
  ; 
  legs 
  

   and 
  feet 
  blue 
  grey.

  mm.; 
  wing, 
  223;

  Adult 
  Female. 
  — 
  The 
  new 
  type 
  of 
  plumage 
  pattern 
  characterizing 
  xanthospila 
  is 
  

   confined 
  to 
  the 
  male, 
  the 
  female 
  being 
  remarkably 
  like 
  the 
  corresponding 
  sex 
  of 
  

   macrolopha. 
  With 
  the 
  exception 
  of 
  the 
  few 
  characters 
  noted, 
  they 
  are 
  identical. 
  

  

  The 
  head 
  and 
  neck 
  present 
  no 
  distinct 
  characters. 
  The 
  upper 
  parts 
  show 
  a 
  less 
  

   development 
  of 
  black, 
  and 
  a 
  corresponding 
  emphasis 
  of 
  pinkish 
  buff, 
  especially 
  on 
  the 
  

   upper 
  neck 
  and 
  mantle. 
  

  

  The 
  greatest 
  dorsal 
  mark 
  of 
  distinction 
  is 
  in 
  the 
  greater 
  uniformity 
  of 
  colouring 
  of 
  

   the 
  back 
  and 
  rump. 
  Instead 
  of 
  carrying 
  out 
  the 
  mantle 
  pattern, 
  there 
  is 
  a 
  rather 
  abrupt 
  

   change 
  on 
  the 
  back. 
  The 
  black 
  markings 
  and 
  the 
  shaft-stripe 
  vanish, 
  leaving 
  the 
  

   plumage 
  of 
  an 
  indefinite, 
  finely 
  mottled 
  buffy 
  grey 
  and 
  dark 
  brown. 
  On 
  the 
  rump 
  a 
  

   curious 
  single 
  line 
  of 
  black 
  feathers 
  extends 
  down 
  the 
  mid 
  line. 
  

  

  The 
  wings 
  offer 
  no 
  important 
  marks 
  of 
  distinction 
  from 
  macrolopha, 
  but 
  the 
  tail- 
  

   feathers, 
  all 
  but 
  the 
  central 
  pair, 
  are 
  very 
  different. 
  They 
  are 
  identical 
  with 
  those 
  of 
  

   the 
  male, 
  being 
  chiefly 
  grey, 
  crossed 
  by 
  an 
  oblique 
  black 
  bar, 
  with 
  a 
  large 
  subterminal 
  

   zone 
  of 
  black 
  and 
  a 
  wide 
  white 
  fringe. 
  Most 
  individuals 
  have 
  more 
  or 
  less 
  distinct 
  

   traces 
  of 
  chestnut, 
  chiefly 
  in 
  the 
  form 
  of 
  irregular 
  marginal 
  spots 
  down 
  the 
  outer 
  webs. 
  

  

  The 
  ventral 
  surface 
  is 
  identical 
  in 
  the 
  two 
  species, 
  except 
  that 
  in 
  xanthospila 
  the 
  

   extremities 
  of 
  the 
  feathers 
  are 
  distinctly 
  whiter.

  Remarks. 
  — 
  The 
  coloured 
  plate 
  in 
  Gould's 
  "Birds 
  of 
  Asia" 
  does 
  not 
  represent 
  a 
  

   typical 
  xanthospila 
  as 
  regards 
  the 
  yellow 
  collar. 
  In 
  fact, 
  I 
  have 
  seen 
  Common 
  Koklass 
  

   from 
  Garhwal 
  with 
  as 
  strong 
  a 
  yellow-buff 
  tinge 
  as 
  this 
  plate 
  shows. 
  The 
  divided 
  black 
  

   line 
  on 
  the 
  plumage, 
  however, 
  marks 
  the 
  bird 
  as 
  distinct 
  from 
  the 
  Himalayan 
  species. 
  

   Elliot's 
  figure 
  is 
  better 
  as 
  regards 
  the 
  yellow 
  collar 
  and 
  the 
  general 
  bluish 
  cast 
  of 
  the 
  

   plumage. 
  The 
  crest 
  in 
  both 
  plates 
  is 
  wrongly 
  drawn.
