On Audouin's Gull. 491 
XXVIIT. — Remarks on Audouin's Gull (Larus audouini). 
By Count E. Arrigoni Degli Oddi, 
AuDouiN^s Gull {Larus audouini) may fairly be considered 
the rarest of the European species, for the other Gulls are 
sufficiently plentiful in the districts in which they breed, 
although they may appear only as stragglers in the south, 
while the subject of this article is very uncommon even in 
the small area to which it belongs. It is a true Sea-GuU, 
and Mr. Howard Saunders, the chief authority on the 
family, describes its habitat in this manner ^ : — " Western 
Mediterranean, chiefly within the Tyrrhenian Sea, but as 
far as the Straits of Gibraltar and a little outside.'^ It 
was included among Grecian species by Lindermayer -}-, 
and among those of Corfu by the Hon. T. L. Powys % (after- 
wards Lord LiKord), while Erhard states that it winters 
in the Cyclades, and Canon Tristram § that it is the com- 
monest Gull on the Lake of Galilee, though his specimens 
all proved to be Common Gulls. Mr. E. C. Taylor || 
thought that some Gulls which he saw near Cairo were of 
this species, and v. Heuglin consequently admitted it to 
his list %. 
The most eastern locality in which Audouiu's Gull has been 
procured is Melissa, in the Sporades, whence two examples have 
been sent to the Sarajevo Museum ^^. To the westward 
Natterer found it at Tarifa, and it has been seen a little 
outside of Gibraltar. Loche has stated that it bred in Algeria, 
but has given no further details ; it has occurred from time 
to time in Corsica and in Sicily, but has only once been 
killed on the mainland of Italy, in Liguria. It is resident 
on the rocky islets round Sardinia, from Spargi and Spar- 
giottott^ Caprera and Maddalena (Straits of Bonifacio) to
