  decided 
  to 
  belong 
  to 
  this 
  form. 
  We 
  have 
  now 
  five, 
  and 
  

   sixteen 
  of 
  yE. 
  columburiiis. 
  

  

  We 
  have 
  also 
  had 
  the 
  gift 
  of 
  a 
  nestling 
  Buteo 
  swainsoni 
  

   obtained 
  at 
  Assiniboia 
  in 
  Canada 
  by 
  Mr. 
  D. 
  L. 
  Thorpe. 
  

   Its 
  stomach 
  contained 
  grasshoppers 
  and 
  mice. 
  It 
  was 
  taken 
  

   with 
  two 
  others 
  from 
  a 
  nest 
  in 
  a 
  large 
  prickly 
  bush 
  12 
  feet 
  

   from 
  the 
  ground, 
  and 
  presented 
  by 
  Mr. 
  Thorpe 
  {cf. 
  ' 
  Zoolo- 
  

   gist/ 
  1893, 
  p. 
  53). 
  

  

  The 
  Buzzards 
  of 
  the 
  New 
  World 
  seem 
  to 
  be 
  still 
  in 
  rather 
  

   an 
  unsettled 
  state 
  as 
  to 
  what 
  are 
  species 
  and 
  what 
  are 
  

   varieties. 
  I 
  believe 
  I 
  am 
  right 
  in 
  saying 
  that 
  Buteo 
  poecilo- 
  

   chrous 
  from 
  Ecuador, 
  coming 
  most 
  closely 
  to 
  B. 
  erythronotus 
  

   (Ibis, 
  1879, 
  p. 
  176), 
  stands 
  good 
  at 
  present, 
  and 
  that 
  there 
  are 
  

   two 
  geographical 
  races 
  of 
  B. 
  borealis, 
  viz. 
  : 
  B. 
  socorroensis, 
  

   Ridgway 
  (which 
  takes 
  its 
  name 
  from 
  the 
  island 
  to 
  which 
  it 
  

   is 
  peculiar), 
  and 
  the 
  light-coloured 
  B. 
  krideri, 
  Hoopes, 
  in- 
  

   habiting 
  that 
  part 
  of 
  North 
  America 
  which 
  extends 
  from 
  

   Texas 
  to 
  Minnesota. 
  If 
  examples 
  of 
  either 
  of 
  these 
  are 
  to 
  

   be 
  found 
  in 
  any 
  collection 
  in 
  England, 
  it 
  is 
  probably 
  only 
  

   in 
  the 
  National 
  Collection, 
  for 
  apparently 
  we 
  have 
  none 
  at 
  

   Norwich, 
  though 
  my 
  father's 
  series 
  of 
  American 
  Buzzards 
  is 
  

   not 
  a 
  small 
  one. 
  

  

  A 
  skin 
  of 
  B. 
  lucasanus 
  with 
  a 
  very 
  light 
  tail 
  was 
  lately 
  

   offered, 
  but 
  not 
  purchased, 
  as 
  Mr. 
  Ridgway, 
  who 
  named 
  it, 
  

   writes 
  to 
  say 
  the 
  species 
  is 
  untenable. 
  My 
  father, 
  up 
  to 
  

   1884, 
  had 
  never 
  seen 
  this 
  North- 
  American 
  form. 
  The 
  Mu- 
  

   seum 
  has 
  only 
  one 
  example 
  of 
  B. 
  borealis 
  harlani 
  {cf. 
  'Auk,^ 
  

   1890, 
  p. 
  205), 
  one 
  of 
  B. 
  costaricensis, 
  and 
  two 
  of 
  B. 
  abbre- 
  

   viatus. 
  Of 
  B. 
  alleni, 
  a 
  subspecies 
  of 
  B. 
  lineatus 
  found 
  in 
  

   Florida, 
  we 
  have 
  a 
  good 
  series 
  of 
  ten, 
  and 
  want 
  no 
  more. 
  

  

  We 
  have 
  the 
  genus 
  Falco, 
  restricted 
  in 
  my 
  father's 
  'List^ 
  

   to 
  seven 
  species 
  and 
  six 
  subspecies, 
  well 
  represented, 
  including 
  

   a 
  pair 
  of 
  very 
  dark 
  F.pealeij 
  Ridgway, 
  from 
  the 
  Kurile 
  Islands, 
  

   in 
  the 
  North 
  Pacific. 
  These 
  birds, 
  which 
  he 
  obtained 
  in 
  

   June 
  1884, 
  immediately 
  after 
  his 
  ' 
  List 
  ' 
  was 
  published, 
  are 
  

   darkest 
  on 
  the 
  breast 
  and 
  belly 
  and 
  under 
  the 
  wings. 
  They 
  

   are 
  both 
  immature 
  and 
  are 
  labelled 
  as 
  shot 
  in 
  September 
  

   1881.
