  the 
  Birds 
  of 
  

  

  be 
  more 
  convenient 
  to 
  treat 
  them 
  as 
  subspeeies 
  ; 
  but 
  I 
  think 
  

   that, 
  as 
  a 
  rule, 
  insular 
  forms, 
  which, 
  on 
  account 
  of 
  their 
  

   isolation 
  are 
  not 
  likely 
  to 
  interbreed 
  or 
  produce 
  inter- 
  

   mediate 
  forms, 
  should 
  be 
  regarded 
  as 
  species 
  rather 
  than 
  

   as 
  subspecies, 
  even 
  if 
  the 
  differences 
  be 
  small, 
  

  

  (G) 
  Linnaeus, 
  in 
  1758, 
  named 
  Catcsby's 
  ^'Bahama 
  Spar- 
  

   row 
  " 
  Fringilla 
  zena, 
  but 
  afterwards 
  transferred 
  this 
  name 
  to 
  

   another 
  member 
  of 
  his 
  large 
  group 
  Fringilla 
  — 
  the 
  Spindalis 
  

   zena 
  of 
  the 
  present 
  epoch 
  — 
  and 
  renamed 
  the 
  " 
  Bahama 
  Spar- 
  

   row 
  " 
  Fringilla 
  bicolor. 
  According 
  to 
  the 
  law 
  of 
  priority, 
  

   both 
  birds 
  should 
  bear 
  the 
  specific 
  terra 
  " 
  bicolor," 
  which 
  

   could 
  not 
  cause 
  any 
  inconvenience, 
  the 
  one 
  being 
  a 
  member 
  

   of 
  the 
  Fringillidai 
  and 
  the 
  other 
  of 
  the 
  Tanagridae.

  The 
  females 
  of 
  all 
  these 
  forms 
  are 
  similar, 
  and 
  to 
  be 
  

   distinguished 
  only 
  with 
  the 
  greatest 
  difficulty.
