  Mr. 
  E. 
  Hartert 
  on 
  the 
  Birds 
  of 
  

  

  Linn^'s 
  description 
  of 
  Tetrao 
  cristatus 
  is 
  founded 
  on 
  

   Brisson's 
  Coturnix 
  mexicana 
  cristata 
  (Orn. 
  i. 
  p. 
  260, 
  pi. 
  xxv.). 
  

   Brisson 
  is 
  of 
  course 
  Avrong 
  in 
  his 
  locality, 
  but 
  clearly 
  figures 
  

   and 
  describes 
  the 
  form 
  from 
  Curayao. 
  As 
  this 
  island 
  was 
  

   always 
  visited 
  by 
  ships, 
  the 
  Abbe 
  Aubry's 
  Museum 
  had 
  very 
  

   likely 
  got 
  specimens 
  from 
  there. 
  Gould 
  (Monogr. 
  Odontoph. 
  

   p. 
  16, 
  pi. 
  ix.) 
  figures 
  the 
  present 
  bird 
  as 
  E. 
  cristatus, 
  but 
  

   his 
  localities 
  are 
  no 
  doubt 
  partly, 
  if 
  not 
  altogether, 
  wrong. 
  

   Berlepsch 
  (/. 
  c.) 
  has 
  already 
  well 
  described 
  his 
  E. 
  gouldi, 
  and 
  

   has 
  pointed 
  out 
  in 
  what 
  respects 
  it 
  differs 
  from 
  E. 
  sonninii. 
  

   The 
  most 
  obvious 
  are 
  the 
  black 
  stripes 
  above 
  and 
  below 
  the 
  

   ear-coverts, 
  which 
  never 
  show 
  in 
  the 
  species 
  from 
  Guiana, 
  and 
  

   the 
  colour 
  of 
  the 
  underparts. 
  The 
  species 
  from 
  Colombia 
  

   (Bogota) 
  is, 
  beneath, 
  more 
  similar 
  to 
  E. 
  cristatus, 
  while 
  its 
  

   head 
  is 
  more 
  like 
  that 
  of 
  E. 
  sonninii. 
  There 
  can 
  be 
  no 
  

   doubt 
  that 
  all 
  three 
  species 
  are 
  quite 
  distinct. 
  

  

  Berlepsch 
  had 
  received 
  only 
  one 
  skin 
  — 
  a 
  female, 
  as 
  stated 
  

   by 
  Peters, 
  but 
  in 
  the 
  fine 
  plumage 
  of 
  the 
  adult 
  male, 
  as 
  

   figured 
  by 
  Gould. 
  My 
  series 
  contains 
  but 
  one 
  female, 
  and 
  

   this 
  is 
  similar 
  to 
  the 
  males 
  in 
  plumage, 
  but 
  has 
  the 
  ear- 
  

   coverts 
  brown 
  and 
  merely 
  traces 
  of 
  the 
  black 
  stripes 
  on 
  the 
  

   sides 
  of 
  the 
  head. 
  I 
  believe 
  that 
  the 
  female 
  gets 
  the 
  black 
  

   stripes 
  when 
  fully 
  adult, 
  and 
  that 
  Peters^s 
  statement 
  was 
  

   right, 
  while 
  Gould 
  has 
  figured 
  young 
  birds 
  as 
  females, 
  for 
  I 
  

   have 
  three 
  young 
  specimens 
  in 
  different 
  stages 
  — 
  one 
  male, 
  

   one 
  female, 
  and 
  one 
  with 
  the 
  sex 
  not 
  determined. 
  All 
  these 
  

   three 
  are 
  alike 
  and 
  agree 
  with 
  Gould's 
  figures 
  of 
  the 
  so- 
  

   called 
  females. 
  The 
  wings 
  of 
  my 
  adult 
  males 
  measure 
  from 
  

   3"9 
  to 
  4'1 
  inches, 
  tarsus 
  1. 
  The 
  iris 
  is 
  dark 
  brown, 
  bill 
  black, 
  

   and 
  feet 
  brownish 
  grey. 
  

  

  This 
  pretty 
  bird 
  is 
  not 
  rare 
  on 
  Aruba 
  and 
  Cura9ao, 
  but 
  is 
  

   not 
  found 
  everywhere. 
  The 
  natives 
  call 
  it 
  " 
  Sockle," 
  a 
  name 
  

   derived 
  from 
  its 
  note, 
  which 
  is 
  uttered 
  very 
  frequently. 
  It 
  

   is 
  much 
  esteemed 
  as 
  food, 
  and 
  sometimes 
  sold 
  in 
  the 
  market 
  

   alive. 
  

  

  This 
  bird 
  is 
  not 
  easy 
  to 
  obtain 
  in 
  any 
  great 
  numbers 
  

   without 
  a 
  dog, 
  as 
  it 
  does 
  not 
  care 
  to 
  fly 
  and 
  is 
  difficult 
  to 
  be 
  

   seen 
  in 
  grassy 
  places. 
  It 
  is 
  not 
  found 
  on 
  Bonaire.
