﻿ORANGE-COLLARED 
  KOKLASS 
  PHEASANT 
  

  

  Pucrasia 
  xanthospila

  and 
  Oustalet 
  

  

  The 
  Koklass 
  Pheasant 
  of 
  Kansu 
  and 
  western 
  Shensi 
  seem 
  to 
  differ 
  from 
  those 
  to 
  

   the 
  east 
  and 
  south 
  in 
  having 
  collars 
  of 
  a 
  decided 
  orange 
  rufous 
  instead 
  of 
  a 
  yellow 
  buff. 
  

   This 
  character 
  is 
  rather 
  variable, 
  and 
  the 
  variation 
  in 
  extent 
  and 
  degree 
  of 
  coloration 
  of 
  

   the 
  collar 
  in 
  xanthospila, 
  render 
  it 
  improbable 
  that 
  this 
  is 
  more 
  than 
  a 
  subspecific 
  

   distinction. 
  As 
  such, 
  however, 
  and 
  as 
  correlated 
  with 
  the 
  occurrence 
  of 
  other 
  subspecies 
  

   of 
  pheasants 
  in 
  Kansu, 
  such 
  as 
  Ithaginis 
  sinensis 
  sinensis, 
  it 
  should 
  certainly 
  be 
  

   recognized. 
  

  

  SUBSPECIFIC 
  CHARACTERS 
  

  

  The 
  chief 
  character 
  of 
  the 
  cock 
  Orange-collared 
  Koklass 
  is 
  the 
  orange 
  rufous 
  colour 
  

   of 
  the 
  collar 
  and 
  anterior 
  mantle, 
  each 
  feather 
  with 
  a 
  narrow 
  shaft 
  stripe 
  of 
  golden 
  

   yellow. 
  In 
  well-marked 
  individuals 
  about 
  half 
  the 
  mantle 
  is 
  included 
  in 
  this 
  zone 
  of 
  

   colour, 
  the 
  collar 
  extending 
  clear 
  around 
  the 
  neck 
  to 
  the 
  chestnut 
  of 
  the 
  mid-breast. 
  

   Even 
  where 
  the 
  two 
  colours 
  come 
  in 
  contact 
  they 
  do 
  not 
  blend. 
  The 
  chestnut 
  of 
  the 
  

   ventral 
  surface 
  is 
  darker 
  than 
  in 
  typical 
  xanthospila, 
  and 
  there 
  is 
  a 
  corresponding 
  

   clearing 
  of 
  the 
  mottled 
  grey 
  areas, 
  the 
  black 
  lines 
  standing 
  out 
  very 
  distinctly 
  against 
  

   their 
  purer 
  pale 
  background. 
  The 
  yellow 
  of 
  the 
  lower 
  sides 
  and 
  flanks 
  is 
  very 
  pro- 
  

   nounced. 
  Everywhere 
  we 
  find 
  an 
  increase 
  of 
  black 
  at 
  the 
  expense 
  of 
  chestnut 
  or 
  rufous, 
  

   as 
  on 
  both 
  the 
  upper 
  and 
  under 
  tail-coverts. 
  

  

  A 
  typical 
  male 
  shows 
  the 
  following 
  measurements 
  : 
  bill 
  from 
  nostril, 
  17 
  mm. 
  ; 
  

   wing, 
  223 
  ; 
  tail, 
  228 
  ; 
  tarsus, 
  66 
  ; 
  middle 
  toe 
  and 
  claw, 
  58. 
  

  

  The 
  Orange-collared 
  Koklass 
  was 
  first 
  separated 
  by 
  David 
  and 
  Oustalet 
  in 
  "Les 
  

   Oiseaux 
  de 
  la 
  Chine," 
  their 
  characterization 
  being 
  as 
  follows 
  : 
  

  

  " 
  Pucrasia 
  xanthospila, 
  var. 
  rttficollis 
  (Chensi). 
  — 
  C6tds 
  du 
  cou 
  d'un 
  roux 
  tres-fonce 
  ; 
  

   tache 
  latdrale 
  blanche 
  peu 
  developpee 
  et 
  entourde 
  de 
  toutes 
  parts 
  par 
  le 
  noir 
  metallique 
  ; 
  

   sous-caudales 
  noires, 
  sans 
  bande 
  marron, 
  avec 
  une 
  tache 
  terminale 
  blanche 
  arrondie 
  et 
  

   non 
  pas 
  anguleuse 
  ; 
  banie 
  mddiane 
  marron 
  moins 
  etendue 
  sur 
  le 
  ventre 
  que 
  dans 
  le 
  

   Pucrasia 
  xanthospila 
  vrai 
  ; 
  teintes 
  noires 
  plus 
  developpdes 
  sur 
  le 
  dos 
  et 
  les 
  ailes." 
  

  

  Their 
  type 
  is 
  now 
  in 
  the 
  Paris 
  Museum.
