Uragus sibiricus and Motacilla personata, and made the 
following remarks :— 
This male and female, Uragus sibiricus sibiricus (Pallas),

Gould, shot on ‘some disused brickfields near West 
St. Leonards, Sussex, on 26 April, 1919, and sent to 
Mr. Bristow. 
I examined this example while in the flesh. 
This seems to be the first occurrence of this Eastern 
Wagtail in Europe.

logs. The eggs were deposited in the centre of a large 
heap of the bark chips and shavings; they were very 
conspicuous in their brown.background, and could easily
