claws blackish ; iris dark brown." Total length 6*8 inches, culmen 

 O'oo, wing '.i-2o, tail 3-o5, tarsus 0'7o. 



Adult female in breeding-plumage. Exactly like the male, but 

 paler, and with much less black on the throat. One obtained on the 

 Volga, on the 11th of May, has the white throat of the winter still 

 intact *. Total length 7 inches, culmen 0-6, wing 3-25, tail 3'8, 

 tarsus 0*8. 



The black throat is evidently assumed by a change of colour in 

 the feathers and not by a direct moult. 



No real specific difference can be found between Eastern and 

 Western examples of the Grey Wagtail. The supposed shorter 

 length of tail in Asiatic specimens is not borne out by the Museum 

 series. On the whole, however, birds from the Asiatic continent 

 have a more richly coloured winter plumage than European spe- 

 cimens, and the throat is often suffused with yellow, but in the 

 summer plumage I cannot detect any difference. 



The tail in European specimens ranges from 3-5 to 3'8 inches, 

 while Asiatic specimens have the tail 3"2 to 3*4 inches, but many of 

 them are quite equal to Eui'opean birds in this respect and have the 

 tail 3-8 inches. Azorean examples do not differ from the European, 



Hab. Throughout the greater part of Europe and Siberia, winter- 

 ing in the plains of India and the Burmese countries, the Malayan 

 peninsula and the Indo-Malayan islands.

* In England we have found the fully-fledged young birds flying about and 

 fed by their parents on the 9th of May ; the old female had a little black on 

 the throat.
