and Scaup, although it is but fair to add that this 

 view is not shared by Mr. Bond, who considers it a 

 hybrid between F.ferina andferruginea. The broad 

 bill, however, and dark colour of the head and dorsal 

 plumage are points which seem to me to indicate a 

 relationship to the Scaup. 



The specimen recorded to have been shot on Rol- 

 lesby Broad, Norfolk*, is in the possession of Mr. 

 J. H. Gurney, who informs me that "it is not the 

 American Scaup, but a Paget's Pochard, Fuligula 

 homeyeri vel ferinoides, now believed to be a hy- 

 brid between the Pochard and Ferruginous Duck." 

 Of this cross Mr. Gurney has a second example, 

 shot at Little Waxham, Norfolk, in February 1859 ; 

 and a third and well-marked specimen is in the col- 

 lection of Mr. Bondf. 



The bird shot near Scarborough in January 1855, 

 and stated (Zoologist 1855, p. 4631; Yarrell, I. c.) to 

 have been an American Scaup, was examined by 

 Mr. John Hancock, who found it to be a female 

 Pochard. Professor Baird has remarked (Birds N. 

 Amer. p. 791) that the F. mariloides of Yarrell is 

 not the F. mariloides of Vigors (Voy. H.M.S. ' Blos- 

 som,' 1839, p. 31), although Yarrell himself thought 

 it was (cf. Hist. Brit. Birds, vol. iii. p. 349). And
