  SUBSPECIFIC 
  CHARACTERS. 
  — 
  The 
  only 
  character 
  which 
  can 
  be 
  trusted 
  in 
  the 
  majority 
  of 
  cases 
  is 
  the 
  

   paleness 
  of 
  the 
  mantle 
  and 
  flanks, 
  these 
  being 
  deeper 
  and 
  warmer 
  in 
  torquatus. 
  I 
  have 
  taken 
  two 
  birds 
  well 
  up 
  

   the 
  Yangtze, 
  which 
  are 
  even 
  lighter 
  than 
  formosanus, 
  but 
  in 
  these 
  cases 
  the 
  green 
  margins 
  were 
  very 
  wide. 
  In 
  

   Formosan 
  birds 
  I 
  have 
  known 
  this 
  green 
  to 
  be 
  almost 
  absent. 
  The 
  females 
  of 
  the 
  two 
  forms 
  are 
  identical.
