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 and ferruginea. 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. Bond f. 
The bird shot near Scarborough in January 1855, 
and stated (Zoologist 1855, p. 4631; Yarrell, /. ¢.) 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 / mariloides of Yarrell is 
not the /. mariloides of Vigors (Voy. H.M.S. ‘ Blos- 
som, 1859, p. 31), although Yarrell himself thought 
it was (cf. Hist. Brit. Birds, vol. iii. p/ 349). And
