This is unquestionably the Alca lorn via of Linnajus, 1758. The 

 name should stand for the species were it not now in use for the genus. 

 It has been more usually employed for troile. The troile of Briinuich 

 is unmistakably this species, but is preoccupied by its Linnean applica- 

 tion for the common species. Svarbag of Briinnich comes next in 

 order: this is based upon the winter plumage, and must stand as the 

 specific designation of the bird. Pallas named it Cephas arra in 1811, 

 and Sabine renamed it Uria Briinnichii in 1818; boUi these names, 

 but particularly the latter, are in very general employ at the present 

 day. Francsii of Leach (1818), also this species, has never had much 

 of a Tun with writers.
