It is widely distributed as a nesting bird in 
Europe, but not far north, and has been known to 
nest in Britain.

GREAT ARCTIC DIVER. 
Case 361, 
In extreme Arctic regions a larger form than 
the Great Northern Diver is found, with the beak 
not only white, but also slightly differing in shape 
from that of its congener. This Arctic form is very 
rare in Britain. Here we have an immature 
specimen, shot by the late Mr. Booth, December 
14th, 1872, on Hickling Broad. Mr. Booth describes 
how, after being wounded, first with the punt gun, 
and then with a shoulder gun, it charged the punt 
open-mouthed and would have come right on board 
if it had not been seized and killed, 
In his ‘ Rough Notes’ he drew attention to the 
large size and weight of the bird, though the 
distinctness of the Arctic species had not then been 
noticed. 
BUFFON’S SKUA, (Mature) 
Case 362. 
A mature bird in fine plumage, from the Borrer 
Collection, is stuffed flying. It was shot while 
swimming about alone on a flooded meadow in the 
Adur level near Henfield, October 7th, 1862. 
See ‘“‘ Birds of Sussex,” p. 280, 
The other two mature specimens were shot 
October 14th, 1879, off Redcar, and were purchased 
(through the good offices of Mr, T. H. Nelson) in 
1898. 
Mature birds of this species in summer plumage 
are readily distinguishable by their long tail feathers, 
but they are rarely seen in Britain. A very fine 
specimen flew close past me while sailing in the 
Outer Hebrides, May 29th, 1894. It was being
