mobbed by two Terns. On the same day I saw a 
large flock of Grey Plover in summer plumage, a 
sight never to be forgotten ; as they turned together 
in the bright sun, they showed their brilliant black 
and white summer plumage to perfection. 
The immature bird to the left of the case also 
comes from the Borrer Collection. It was taken 
with a floating bait off the Chain Pier, at Brighton, 
November, 1844. The white head is very unusual 
and observable. 
SOOTY SHEARWATER. 
Case 363. 
This species is an ocean wanderer. So far as the 
Atlantic is concerned, it is only known to breed in 
the southern hemisphere ; but when not nesting it is 
found over the whole ocean and especially on the 
great fishing grounds. It rarely visits our coasts. 
Of the two specimens in the case, the bird with 
outspread wings was picked up dead after a gale 
about the end of June, 1850, under the cliff at Seaford, 
Sussex, by Tom Mills, a local fisherman, and brought 
to Mr. Dennis of Bishopstone. 
The other specimen was shot off Hastings on 
September 3rd, 1890, 
Both of these birds are from the Borrer 
Collection.

Case 364. 
This immature specimen was shot beyond 
Rottingdean toward the end of the winter of 1889-90 
by a Brighton College boy. It is an Arctic species, 
seldom wandering so far south even in the immature 
state. Mature birds have very rarely been observed 
even in the extreme north of Britain. 
The samphire and wild stock in the case were 
brought from the cliffs near Rottingdean.
