  " 
  constitute 
  a 
  very 
  homogeueous 
  order, 
  Mliich 
  docs 
  not 
  admit 
  

   of 
  division 
  into 
  easily 
  definable 
  or 
  sharply 
  defined 
  groups/^ 
  

  

  Having 
  shown 
  that 
  Garrod^s 
  attempt 
  to 
  arrange 
  them 
  

   according 
  to 
  their 
  anatomical 
  structure 
  does 
  not 
  lead 
  to 
  

   satisfactory 
  results, 
  the 
  author 
  reverts 
  to 
  external 
  characters, 
  

   and 
  adopts 
  a 
  system 
  not 
  very 
  different 
  from 
  those 
  propounded 
  

   in 
  1872 
  by 
  Sundevall, 
  and 
  in 
  1880 
  by 
  the 
  Editor 
  of 
  this 
  

   Journal 
  ('Ibis/ 
  1880, 
  p. 
  406). 
  According 
  to 
  this 
  plan 
  the 
  

   order 
  Columbse 
  contains 
  two 
  suborders 
  — 
  Columbaj 
  and 
  Didi. 
  

   The 
  Columbse 
  are 
  divided 
  into 
  five 
  families 
  — 
  Treronidae, 
  

   Columbidne, 
  Peristeridfe, 
  Gouridoe, 
  and 
  Didunculidre. 
  

   Calcenas 
  is 
  placed 
  as 
  a 
  subfamily 
  by 
  itself 
  at 
  the 
  end 
  of 
  the 
  

   Peristeridae. 
  We 
  are 
  rather 
  o£ 
  opinion 
  that 
  the 
  full 
  rank 
  of 
  

   a 
  family 
  might 
  have 
  been 
  accorded 
  to 
  this 
  anomalous 
  form. 
  

  

  The 
  following 
  generic 
  and 
  subgeueric 
  terms 
  are 
  proposed 
  

   as 
  new 
  in 
  this
