Audoubt's Gull. 493 
Mr. Schiavazzi has acknowledged that he was mistaken as to 
two specimens caught at Pirano in Istria. The latter gentle- 
man has also mentioned an example in the Museum at Vienna^ 
obtained by Natterer in 1815 ; but this may be that from 
Tarifa^ and in any case the date is previous to Payrandeau^s 
description of the bird in 1826. I could not find any trace 
of this specimen in the Museum. 
Audouin^s Gull was found nesting on the island of Mai di 
Ventre by the lateMarquis Nerli, and onToro by Lord Lilford, 
while it breeds on the Columbretes, in the Gulf of Valencia, 
and has probably been overlooked in many of the rocky islets 
off Sardinia, where Larus cachinnans is found. The eggs 
have been fully described by Mr. Gates in the ' Catalogue of 
Birds' Eggs in the British Museum ' (i. p. 217). 
The Italian Museums and private collections which possess 
specimens of Audouin's Gull are the following : — 
a. Oi\'ic Museum of Milan (one specimen from Elba). 
b. Civic Museum of Genoa. 
c. Collection of Marquis Pinelli-Gentile of Genoa (the only Ligurian- 
killed example). 
d. R. Museum of Florence (a beautiful series of seven or eight speci- 
mens, with a young bird and eggs; all from the island of Mai di 
Ventre). 
€. Collection of Mr. Tonietti at Portoferraio (Elba) (two specimens 
from Elba). 
/. Collection of Marchioness Paulucci of Florence (one specimen 
from Sardinia). 
g. R. Museum of Cagliari (three adult specimens). 
h. R. Museum of Palermo (five adult specimens). 
i. Collection of Mr. J. Whitaker at Malfitano, Palermo (a "beautiful 
series of seven or eight specimens which belonged to the late Lord 
Lilford). 
j. My Collection (sixteen specimens, with some immature and V'oung 
birds, and also some that are half -grown, about which I shall 
speak further). 
I shall not enter into the habits of the species, as they are 
sufficiently well known, but will proceed at once to describe 
the plumage of the young in its first dress, which I am 
especially anxious to put on record, as it is not given by
