  Greenland 
  is 
  a 
  country 
  of 
  special 
  interest 
  to 
  European 
  

   ornithologists, 
  and 
  it 
  is 
  always 
  agreeable 
  to 
  liave 
  additional 
  

   information 
  on 
  its 
  avifauna. 
  The 
  Heilprin 
  expedition 
  of 
  

   1891 
  did 
  not 
  make 
  any 
  serious 
  advance 
  in 
  our 
  knowledge 
  of 
  

   this 
  subject, 
  but 
  vehat 
  was 
  eflFected 
  by 
  Dr. 
  Wm.

   and

  The 
  

   147 
  specimens 
  collected 
  are 
  referred 
  to 
  21 
  species, 
  most 
  of 
  

   which 
  were 
  found 
  to 
  be 
  in 
  full 
  breeding-plumage.

  have 
  now 
  the 
  concluding 
  portion 
  of 
  M. 
  Suchetet^s 
  

   exhaustive 
  account 
  of 
  hybridism 
  in 
  birds 
  {cf. 
  Ibis, 
  1892, 
  

   p. 
  344) 
  ; 
  it 
  is 
  devoted 
  to 
  such 
  cases 
  as 
  have 
  occurred 
  in 
  the 
  

   Passeres 
  and 
  Picarise. 
  The 
  author 
  notices 
  not 
  only 
  clear 
  cases 
  

   of 
  hybridism, 
  such 
  as 
  between 
  Carduelis 
  elegans 
  and 
  Cannabina 
  

   linota, 
  but 
  also 
  transitional 
  forms 
  between 
  representative 
  

   species, 
  such 
  as 
  those 
  between 
  Coracias 
  indicus 
  and 
  C. 
  affinis, 
  

   which 
  occur 
  on 
  the 
  borders 
  of 
  their 
  respective 
  ranges. 
  He, 
  

   however, 
  distinguishes 
  these 
  in 
  his 
  "Conclusions.^'' 
  The 
  most 
  

   remarkable 
  instances 
  of 
  hybridization 
  known 
  in 
  the 
  Passeres 
  

   are 
  perhaps 
  those 
  between 
  the 
  North 
  American 
  Hehninthophila 
  

   pjinus 
  and 
  H. 
  chrysopjtcra 
  (which 
  produce 
  the 
  forms 
  called 
  

   H. 
  leuco-bronchialis 
  and 
  H. 
  laitTencii) 
  and 
  the 
  so-called 
  

   Ptilonorhynchus 
  raionsleyi, 
  supposed 
  to 
  have 
  originated 
  from 
  

   a 
  cross 
  between 
  Sericulus 
  chrysocephalm 
  and 
  Ptilonorhyn-
