' Tlu! prcfercnco is hero given to Colymbus immcr, BituNN., overC imbrr, Oi:nn., only for the reiisim 

 that there may be a question as to whether Ounncrns is acceptable as a liinomialist. He is unquestionably 

 as much so as Bartram, whose identifiable names are not challenged, and furthennore describes his species 

 much more accurately and scientifically than did Bartram ; while his diagnoses are acconqtanied by per- 

 fectly recognizable plates. (See SriaMUJKii, Proe. V. S. Nat. Mus. Vol. t>, p. 37, and The Auk, April, 

 1884, p. 119.) Our reasons for preferring imtivr to torqiutfits are that the latter <loos not o<!cur in 

 the twelfth edition of Linnivus's Systema Natuiw, while the former does, and may therefore be taken by 

 those ornithologists who do not recognize names dating earlier than 1700.
