70 Dalgleish on North American Birds in Europe. 
9. One, Bridlington, Yorkshire. Boynton (fide Sclater and Bree), 
Zool., 1870, p. 2021. On this specimen vide also Zook, tom. cit., pp. 
2067 and 2100. 
Obs. — Messrs. Newton, Dresser, and Harting concur in considering 
all the above occurrences very doubtful , and that in most cases they had 
been confounded, either with A. spinoletta, the Water Pipit of Continental 
Europe, or a rufous-breasted variety of A. obscurus, the Kock Pipit, found 
in Scandinavia. 
Heligoland. 1. One, a young bird. G'atke, J. f. O., 1856, p. 71. 
In coll, of Herr H. G'atke. 6 Nov., 1851. 
2. One, adult. G'atke, Naum., 1858, p. 423. In coll, of Herr H. Gatke. 
17 May, 1858. 
Obs. — There being so much hesitation about the admission of the 
British specimens of this species, it. may be well to mention that those ob- 
tained at Heligoland, by Herr G'atke, are undoubted. Mr. Seebohm states 
that this bird, being common in Alaska, Kamtchatka, and Japan, the 
specimens here recorded have probably strayed across Siberia to Heligo- 
land. t

said to have been killed in Cambridgeshire, but in a later communication 
(Zook, 1852, p. 3507), recording the two mentioned above, he states that 
he has been unable to authenticate the Cambridgeshire occurrence.
