  Seen, 
  but 
  not 
  procured. 
  Possibly, 
  however, 
  it 
  was 
  not 
  

   this 
  form, 
  but 
  the 
  continental 
  one.

  There 
  is 
  hardly 
  a 
  bird 
  that 
  presents 
  more 
  local 
  variation 
  

   than 
  this 
  pretty 
  little 
  Ground-Dove. 
  North- 
  American 
  

   authors 
  distinguish 
  between 
  the 
  form 
  inhabiting 
  the 
  " 
  South- 
  

   Atlantic 
  and 
  Gulf 
  States 
  " 
  and 
  the 
  one 
  reaching 
  from 
  the 
  

   South-western 
  States 
  throughout 
  Mexico. 
  The 
  former 
  they 
  

   used 
  to 
  call 
  C. 
  passerina, 
  but 
  later 
  on 
  it 
  was 
  named 
  C. 
  pas- 
  

   seri^ia 
  purpurea 
  by 
  Maynard, 
  and 
  has 
  quite 
  recently 
  been 
  

   renamed 
  C. 
  passerina 
  terrestris 
  by 
  Chapman. 
  

  

  I 
  have 
  collected 
  a 
  large 
  series 
  from 
  the 
  three 
  Dutch 
  West- 
  

   Indian 
  Islands. 
  All 
  of 
  them 
  differ 
  from 
  the 
  forms 
  of 
  other 
  

   countries, 
  that 
  I 
  have 
  seen, 
  in 
  their 
  pale 
  colour 
  throughout, 
  

   and 
  especially 
  on 
  the 
  under 
  tail-coverts, 
  in 
  the 
  rather 
  shorter 
  

   wing, 
  and 
  in 
  the 
  base 
  of 
  the 
  bill 
  being 
  yellow, 
  not 
  red. 
  On 
  

   Porto 
  Rico 
  and 
  St. 
  Thomas 
  I 
  shot 
  examples 
  of 
  a 
  different 
  

   race, 
  much 
  richer 
  and 
  darker 
  in 
  colour 
  everywhere 
  ; 
  the 
  base 
  

   of 
  the 
  bill 
  deep 
  red, 
  not 
  yellow, 
  and 
  the 
  wing 
  also 
  short. 
  

  

  The 
  typical 
  form 
  of 
  Linnseus^s 
  C. 
  passerina 
  must 
  be 
  the 
  

   Jamaica 
  bird 
  {cf. 
  Berl. 
  J. 
  f. 
  O. 
  1892, 
  p. 
  97), 
  which, 
  if 
  any- 
  

   thing, 
  has 
  the 
  wing 
  a 
  little 
  longer 
  on 
  the 
  average 
  than 
  the 
  

   one 
  from 
  Porto 
  Rico, 
  and 
  stands, 
  as 
  regards 
  coloration, 
  

   between 
  the 
  pale 
  and 
  dark 
  forms. 
  The 
  Eastern 
  North- 
  

   American 
  bird 
  is 
  closely 
  allied 
  to 
  this 
  form, 
  but 
  it 
  is 
  said 
  to 
  

   have 
  the 
  base 
  of 
  the 
  bill 
  red, 
  and 
  the 
  Aving 
  is 
  certainly 
  a 
  

   little 
  longer. 
  It 
  might 
  therefore 
  be 
  distinguished 
  sub-
