Allied Species and Representative Forms.—C. islandica 
(Barrow’s Golden-eye), a larger bird, the male of which has 
a more fully-developed crest and more purple shading on 
the head, is the representative in Iceland and Greenland, 
while a larger form with no difference in plumage from our 
bird, inhabits North America (Saunders). 
BUFFEL-HEADED DUCK. Clangula albeola (Linneus). 
Coloured Figures.—Dresser, ‘ Birds of Hurope,’ vol. vi, pl. 439 ; 
Lilford, ‘Coloured Figures,’ vol. vii, pl. 49. 
This beautiful little bird, smaller than the Golden-eye, 
but somewhat similar to it in markings, is an inhabitant 
of the New World. There are but four substantiated 
records of its occurrence in Britain, the specimens secured 
being ali males. One was obtained in the winter of 1830 
at Yarmouth; it is preserved in the Norwich Museum 
(Lubbock, ‘ Fauna of Norfolk’); another in January, 1865, 
from the Loch of Loriston, Aberdeenshire ; a third “ many 
years ago”? from the Loch of Strathbeg; this specimen 
1s preserved in the Banff Museum (Gray, ‘ Birds of West 
Scotland’). The fourth was taken in the winter of 1864- 
1865, at Bridlington, Yorkshire, and is now in the collection 
of Mr. Whitaker, of Rainworth. 
As yet no examples have been recorded from Ireland.
