24 THE ZOOLOGIST.- 
thirty yards long. It was in splendid plumage, and as far as 
could be discerned had no physical ailment. I watched it closely 
for ten days through glasses. At irregular periods of the day it 
dived for food, giving a kind of shoulder thrust as it did so, and 
remaining under exactly thirty seconds every time. It was 
particularly jealous of the too close approach of the other 
feathered inhabitants of the water—four Dabchicks, a female 
Mallard, and two Waterhens—and when they approached, it 
swam up and chased them away. Occasionally it went on shore 
and sat on some half-submerged grass-banks. On April 9th a dark 
bird, undoubtedly a female, arrived from the south at about 
1.30 p.m., and settled beside the male. They swam about for 
some time, then the female rose, the male following, and they 
circled round several times, the former ultimately departing in 
a northerly direction ; the male, however, returned to the water. 
The following morning he, too, had departed. 
GoLpEN-Eye (Clangula glaucion).— An occasional winter 
visitor. On Jan. 2nd, 1906, a large flock was observed at 
St. Mary’s Island, all the birds being immature or females. 
Males in adult dress are very rare; my brother observed one on 
Oct. 26th, 1909. 
Lone-TaiteD Duck (Harelda glacialis)\—A very rare visitor 
in winter. 1 can find but three records. An immature male 
changing to summer plumage was shot off Seaton Sluice on 
Jan. 15th, 1894, and is in the Hancock Museum. Mr. R. 
Duncan informs me that he saw the second specimen shot when 
it was coming through the passage at St. Mary’s; it was a 
female. Two birds shot by a Mr. Marshall off Cullercoats, and 
set up by Mr. Taylor, are now in the possession of Mr. Gascoyne 
of that village. 
Hiper Duck (Somateria mollissima).—Although its nesting- 
haunts are so close—the Farne Islands—yet but few specimens 
have occurred, and these immatures, and from this we may 
gather that this species does not shift its quarters much. The 
following are the only authentic occurrences. An immature 
male shot at St. Mary’s, and now in the Hancock Museum. 
From Jan. 29th to Feb. 14th, 1908, I observed an immature 
female swimming in Cullercoats Bay during heavy storms. It 
frequently dived and brought seaweed to the surface, which it
