 This species, the Yellow Wagtail of British ornithologists, 

 has been found to differ from the bird so called by those 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 only 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 Ray 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 Ray, 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.

97. BUDYTES GOULDI. BLUE-HEADED QUAKETAIL. 

 Male with the head, hind neck, and ear-coverts greyish- 

 blue ; a white band over the eye ; the upper parts yellowish- 

 green, the lower bright yellow, the two lateral tail-feathers 

 on each side partially white. Female similar, but with the 

 head brownish-grey, the upper parts tinged with greyish- 

 brown, and the throat white. Young light brownish-grey 

 above, the wings and tail dusky, the lateral feathers of the 

 latter as in the adult, the lower parts yellowish-white, with 

 an obscure dusky crescent on the fore neck.
