312 STERNA CASPIA.—LARUS SABINIT. 
[§ 4508. Siv.—Sylt. From Dr. Kjerbolhng, 1856. 
Bought for me, if I remember right, by Mr. Wolley, and, if so, at the same 
time as the fifteen above entered (§ 4505). } 
[§ 4509. Siv.—Sylt, 1861. From Mr. John Baker. 
These I obtained from Mr. Baker soon after his return from the island, to 
which he went in that year. His marks shew that they were all from different 
nests, and I selected them out of his booty, consisting of more than one 
hundred, though I believe Mr. Sealy had the first choice. | 
[§ 4510. Zwo—Bay of St. Paul, Newfoundland, 12 June, 
1867. From Mr. Henry Reeks. 
Of this species Mr. Reeks, in his “ Notes on the Zoology of Newfoundland ” 
(Zoologist, 1869, p. 1851), observes :—“ A tolerably common summer migrant, 
and breeds on many of the islands along the coast : I obtained eggs in the Bay 
of St. Paul. The settlers call it the ‘ Mackerel bird.’ ”’] 
[§ 4511. Zwo.—Warba, Persian Gulf, 3 April, 1878. From 
Colonel Butler, through Mr. Howard Saunders, 1879. 
Part of Colonel Butler’s note furnished to Mr. Oates has been already given 
(§ 4405), and there is no need to print it twice, as that gentleman has done 
(Nests and Eggs of Indian Birds, ed. 2, pp. 296 and 3505). } 
LARUS SABINII, J. Sabine. 
SABINE’S GULL. 
Proc. Zool. Soc. 1861, p. 401. 
[§ 4512. One—Taimyr Peninsula, 10 July, 1843. From 
Dr. A. 'T. von Middendorff, through Dr. Baldamus, 
1861. 
This is one of the treasures, marked “ Unicum,” which Dr. Baldamus was so 
good as to obtain for me. In his work (Sib. Reise, II. ii. p. 244) Dr. von 
Middendorff says that this Gull appeared on the Taimyr (N. lat. 73° 75’) on the 
dth of June, and thence spread about so that he found it breeding abundantly 
on the lakes of the tundra and the alluvial islets in the river, in company with
