June, 1867. In May, 1871, four were killed by Mr. E. T. 
Booth, at Breydon, and in May, 1873, the same for- 
tunate gun bagged five, and saw several more at Hick- 
ling.t In June, 1883, two were seen at Barton, and 
one of them killed on the roth at Hickling. 
BLACK TERN.—Used to breed with us, inland, but is now 
a passing summer migrant, rather rare. 
GULL-BILLED TERN.—Has occurred at Yarmouth eight 
times. The following are the dates:—April 14, July 31, 
September 1 (two), 1849; May 24, 1850; July, 
1851; May 8 (two), 1878. 
Common TERN.—A common summer visitant. The colony 
at Blakeney has increased since the passing of the 
several Bird Acts. 
ARCTIC TeERN.—A summer visitant. I have never felt 
sure whether any breed at Blakeney or not, but even 
as a migrant it is much rarer with us than the com- 
mon tern, from which it may be distinguished at 
all ages by its short tarsus. 
ROosEATE TERN.—One in Lord Lilford’s collection was shot 
at Hunstanton by Mr. Hardy, July ro, 1880, and this 
appears to be the only authenticated specimen.” 
SANDWICH TERN.—A summer migrant, or perhaps more 
correctly, a spring and autumn one, very far from 
common. 
CasPpIAN TERN.—This very rare summer visitant is believed 
to have occurred no less than nine times, but it is 
more than twenty years since the last was shot.*

Horsey, was, I understand, not killed in Norfolk.
