LARUS CACHINNANS.—L. ARGENTATUS. 
LARUS CACHINNANS, Pallas. 
[§ 4570. Onve.—< South Russia.” From Herr A. Heinke, of 
Kamusclin, through Dr, Albert Giinther, 1862. | 
[§ 4571. Oue.—Greece, 3 May, 1863. From Dr. Kriiper, 
through Herr Seiderisacher, 1864. 
Received under the synonym of Z, michahellesi. The only notes published 
by Dr. Kriiper on this bird that I can find are in his Catalogue (Griechische 
Jahreszeiten, 1875, pp. 301, 302), wherein it is regarded as specifically 
identical with Larus argentatus, and stated that it breeds on rocky uninhabited 
islands about the middle of April.] 
[§ 4572. Lhree—tIsland of Marmora, Turkey, 19 May, 1866. 
From Mr. Robson, of Ortakeuy, near Constantinople. | 
LARUS ARGENTATUS, Liuneus. 
IIERRING-GULL. 
§ 4573. Five.—Yorkshire Coast, 1843. 
From Wilson, of Bridlington, who had numbers of them from some 
of the cliffs in the neighbourhood. It is almost impossible to 
distinguish them from the eggs of the [Lesser] Black-backed Gull, 
which fortunately very rarely breeds there. In September the Herring- 
Gulls were abundant at Scarborough, and but very few Kittiwakes. 
The one in our garden [at Beeston] was born at the South Foreland, 
and kept at St. Margaret’s, in 1841. Every intermediate variety of 
the egg may be found. 
§ 4574. One.—Treshenish, Argyll, 1844. From Mr. G. D. 
Rowley. 
Taken by Mr. Rowley in Treshenish Island, near Staffa.
