This species, the Yellow Wagtail of British ornithologists 
has been found to differ from the bird so called by thoL of 
the Continent, which has the head greyish-blue, although in 
all other respects precisely similar. Supposing then that Lin- 
naeus by his Motacilla flava meant the Grey-headed bird of the 
Continent, of which a very few individuals onlv have been met 
with in this country, Mr Gould and the Prince of Canino 
named our common bird Budytes Rayi. But Linnaeus has re- 
ferred to Kay and Willoughby, as well as to Gesner and Aldro- 
vandi, and therefore his Motacilla flava includes both alleged 
species. If the present then be named after Kay, I think the 
other ought to be named after Mr Gould, who first distinguish- 
ed the two. The Green-headed Quaketail is migratory, arriving 
in the end of spring, and disappearing in September. Its habits 
are similar to those of the Wagtails, but it is more addicted 
to searching for insects on plants. Its nest is lined with hair 
and the eggs, four or five in number, are pale brown, sprinkled 
with dots of a darker tint. ^
