 One, CO. Dublin : Blake Knox, Zool., 1866, p. 306. 

 One on the Dee Marshes, Cheshire, 1891 : Congreve, Zool., 



1897, p. 510; Coward and Oldham, " Birds of Cheshire," 



p. 229. 



Obs. The occurrence of this bird in the British 

 Islands, even as a rare straggler, is extremely doubt- 

 ful, and it is only included here in view of the above- 

 mentioned records, which it has not been possible to 

 verify. It has been recorded as "a summer visitant 

 to St. George's Channel" (Austin, Ann. Nat. Hist., 

 vol. ix. p. 435) ; but doubtless Hydrochelidon nigra 

 is the species intended. 



WHITE-WINGED BLACK TERN. Hydrochelidon leu- 

 coptera, Schinz. Length, 9*25 in. ; bill, 1 in. ; wing, 

 8-25 in. ; tarsus, 0-75. 



Hab. Central and Southern Europe in summer; 

 wintering in Africa, Australia, and New Zealand. 



One on the Shannon, 1841 : M'Coy, Ann. Nat. Hist, vol. 

 XV. p. 271. In the Dublin Museum. Thompson sa3^s 

 (" Nat. Hist. Irel. (Birds)," vol. iii. p. 307) that this bird 

 was shot by Mr. John Hill, not on the Shannon, but 

 on the Liffey, near the Pigeon-house Fort, Dublin Bay, 

 in October 1841.
