of golden plovers and other migrants are heard whistling and 
calling over this city, attracted by the glare of the lamps, the harsh 
cries of this gull, apparently in considerable numbers, may he 
readily distinguished at times ; and there can be, I think, no 
question that a migratory movement is then taking place. 
The black head in this species is peculiar to the breeding season, a 
slight patch only on the nape of the neck existing in its winter 
dress, and, as is customary with all gulls, the young are two, if not 
three, seasons in acquiring their full plumage. 
I never vet saw a mottled bird at Scoulton on their first arrival, 
and it is rare even to see one with a black bar at the base of the 
tail, the last stage of immaturity ; but though in this state, they 
have been known to breed, still, as a rule, these birds do not seem 
to pair off or frequent their nesting stations until they have 
acquired their full adult plumage. This, no doubt, accounts for 
the numbers seen throughout the summer on all parts of our coast, 
feasting their idle hours away, till in due time (provided always 
they keep clear of ladies’ hats), the joys, labours, and anxieties of 
the nuptial state are theirs, and with a burst of parental indignation 
they witness for the first time the inevitable robbery of their new- 
laid eggs.

Mr. President, Ladies, and Gentlemen — It is only since I 
seriously began to look for materials in the composition of the 
present paper, that I became aware of the importance of the task 
I had undertaken. So little has been said on the subject, that I 
am almost in the unpleasant position of being the first to open it 
for discussion. If my remarks should have the cflcct, whether 
directly or indirectly, of giving iis more light on the subject ot the
