Sub-family b ALCIN^I True Auks 



Nostrils naked and not reached by the feathering at the 

 base of the bill. 



Genera, Alle, Sea Dove, Dovekie. 



1 Synthliborliamplius, 2 species. 

 Bracliyrliamphus, 5 species. 



Una, The True Guillemots (3 species). 

 Lomvia, The True Murres (4 species). 



Utamania, The Razor-billed Auk. 

 Alca, The Great Auk. 



The above generic equivalents for the Auks and Puffins is 

 correct, as the family is now treated by our best ornitholo- 

 gists. It would be unwise to enter into a discussion of old 

 relations and old synonyms. A very few of them may be 

 mentioned only, such as Aha, Phalaris, Utamania, and Uria, 

 as being general names for the Auks ; Mormon for the Puf- 

 fins ; Ceppus and Colymbus for the Black Guillemot and 

 its allies : Colymbus was also used for many of the other spe- 

 cies of Guillemots. 



We have omitted, in the above pages, the discussion 

 of a large number of Debatable Questions, especially 

 concerning Individual Species and the admission of 

 genera based upon them. We hope, however, that no 

 essential genus has been left out.
