therefore, applied to it the specific term mariloides, as 

 mentioned by the late Mr. Vigors, in a quotation to be 

 hereafter noticed. 



The British Scaup Duck is well known in the United 

 States, and the accounts of the American ornithologists, 

 Messrs. Wilson, Audubon^and Nuttall, appear to refer to 

 the species which immediately precedes the present subject 

 in this work. 



Sir W. Jardine, writing of the Scaup Duck, observes, 

 " In the Northern Zoology, the American specimens are 

 said to be smaller, but no other distinctions could be per- 

 ceived ; a single northern specimen which I possess, agrees 

 nearly with the dimensions given of the smaller kind, and 

 I can see no other important difference ; but there are also 

 larger-sized birds, known to the natives by the addition 

 of Jceetchee to the name, and I think it probable that two 

 birds may be here confused, which future observations will 

 allow us to separate." 



Mr. Audubon, in his last work on the Birds of America, 

 admits marila and mariloides as distinct species. This 

 species occurs at Bermuda. 



Sir John Richardson's remarks on the Scaup Duck in 

 the Fauna Boreali- Americana, are as follows : " Our 

 specimens are smaller than English ones killed in the 

 winter, the head, bill, wings, and legs, in particular, being 

 proportionally smaller, and the bill less high at the base. 

 A variety, nearly corresponding with the English one in 

 size, is also found in the fur-countries, where it is distin- 

 guished by the epithet of keetchee (bigger) : but an at- 

 tentive examination of a number of specimens disclosed 

 no peculiarities which could characterise it as a distinct 

 species, except its size. The undulated markings on the 

 back and wings are darker, and less extended than in the 

 English specimens." Mr. Swainson adds in a note at the
