Is believed to be at least an occasional visitant. 
It is included on tlie following testimony. In a letter to me from 
Mr. R. Ball, dated Dublin, June the 1 9th, 1846, it was stated, that 
a few days before, when at Roundwood, he had seen a specimen 
of the true Motacilla alba , as distinguished from M. Yarrellii. 
He remarked: — “We watched it for some time, though at a 
short distance from us, with a small telescope used for such pur- 
poses; its beautiful plumage was very distinct from that of the 
common species, and its habit much more sedate than is usual with 
wagtails : it f wagged 9 but little, and walked about demurely. — I 
am quite sure that I have often seen the species before.” As the 
bird was not actually obtained, its occurrence would not be in- 
serted here, without my having perfect reliance on the knowledge, 
and acute observation, of my informant. The preceding note was 
communicated to the Annals of Natural History, vol. xviii. p. 311 
(1846). Mr. R. Chute, of Blennerville, co. Kerry, had written to 
me in Eeb., 1846, that he believed this species was found there. 
This wagtail has only for the last few years been known as 
British, from specimens obtained at Kingsbury, Carlisle, and 
Ealmouth. (Yarr., B. B. i. 404.) 
GREY WAGTAIL. 
Yellow wagtail (popularly in Ireland). 
Motacilla boarula , Linn. 
This beautiful and graceful species, though much less 
common than the pied wagtail, is extensively, but 
not universally, distributed over Ireland.
