CATALOGUE OF BIRDS. 117 



WHITE WAGTAIL. 

 Case 134. 



A few of these birds may be observed on the south 

 coast during April and early in May. The greater 

 part of those I have noticed appeared to be making 

 their way from west to east. 



There seems to be considerable doubt among 

 naturalists as to whether this is a true species, or only 

 a continental form of our common Pied Wagtail. 



The specimens in the case were obtained between 

 Shoreham and Lancing, in Sussex, in April, 1872. 



GREY WAGTAIL. (AUTUMN.) 

 Case 135. 



There are several localities in Sussex and other south- 

 ern counties where these birds may be met with during 

 autumn and winter. 



I ha\ 7 e repeatedly observed them in Scotland fre- 

 quenting the rocks on the sea-shore at this season. 



One of the specimens in the case was shot on the 

 banks of the river Ouse, near Lewes in Sussex, in 

 November, 1873, and the other at Canty Bay, in East 

 Lothian, in October, 1874. 



KNOT. (SUMMER.) 

 Case 136. 



The number of Knots that visit our shores during 

 summer appears to have fallen off greatly of late years. 

 This I can in no way account for, as they seem fully 

 as plentiful at other seasons.
