288 MOTACILLIDJE. 



plumage is yellowish grey with indications of a pale pectoral 

 crescent. 



After the first autumn moult, the young bird resembles the adult 

 in normal winter plumage, but has the posterior part of the crown, 

 the nape, and the hind neck grey like the back, and the white parts 

 of the head tinged with primrose-yellow. 



The full summer plumage is probably assumed the first spring, 

 except in the case of the females, which appear to be much longer 

 than the males in acquiring the black on the crown, nape, and 

 hind neck, these parts being at first a pale brown, and afterwards 

 for some time black mottled with brown. 



Bill black, bluish below ; iris brown ; legs and claws dark brown 

 or nearly black. 



Length nearly 8 ; tail 3*6 ; wing 3'5 ; tarsus '85 ; bill from 

 gape -75. 



Distribution. A winter visitor to the whole Empire, as far south 

 in the peninsula of India as Belgaum, and in Burma as Moulmeiu. 

 A few specimens of this species are occasionally killed in summer, 

 and I have seen a July specimen from Sambhar. Indian birds of 

 this species appear to winter in Northern Asia. The range of this 

 Wagtail extends to Europe and Northern Africa. 



M. baicalensis is a race of M. alba with the wing-coverts almost 

 entirely white. It inhabits Eastern Siberia, and in the British 

 Museum there is a specimen said to have been killed in " India." 

 No reliance can, however, be placed on this locality. 



M. persica is another race of M. alba, with the wing-coverts 

 almost entirely white, and the black of the hind neck almost in 

 contact with the black of the breast. It inhabits Persia.
