176 OUR SUMMER MIGRANTS. 



The only Swallow hitherto observed in Green- 

 land — and that only on two occasions — is, ac- 

 cording to Professor Reinhardt, the American 

 Swallow, Hirundo rufa of Bonaparte. Now, 

 Bonaparte identifies this (Geogr. and Comp. 

 List, p. 9) with H. rufa of Gmelin, and Pro- 

 fessor Baird considers Gmelin's bird to be the 

 South American species, for which H. erythro- 

 gaster of Boddaert is the oldest name. If this 

 identification be correct, one would certainly ex- 

 pect the bird found in Greenland to be the North 

 American species, H. rufa of Vieillot, not Bona- 

 parte, now generally better known by its older 

 name, H. horreorum of Barton. The late Mr. 

 Wheelwright observed the Common Swallow in 

 Lapland, where he saw it hawking about over 

 the high fells at Quickjock, and he fancied it 

 was even commoner there than at Wermland, in 

 Sweden, where it is also an annual summer 

 visitant.' Throughout Europe generally, as al- 

 ready remarked, it is everywhere distributed in
