284 Mr. H. Whistler on the [Ibis, 



table below with the table given for A. campestris. No 

 specimens of A. rufulus were preserved from Jhang, but 

 9 males and 3 females from other localities which I have 

 measured give the followino- results : —

Motacilla flava beema Sykes. (6 skins.) 



Sykes's Yellow Wagtail was by far the most abundant of 

 the Wagtails in both the spring (March) and autumn 

 migrations (September). The total number of individuals 

 passing along the course of the Chenab liiver at these seasons 

 must be incredibly large. 



Note. — The difficulty of identifying Wagtails in the field 

 in their various stages, and the vast numbers of these birds 

 that winter in, or migrate through the district, have made it 

 quite impossible for me to keep accurate notes as to the 

 occurrence of the different species ; for one bird shot or 

 otherwise identified, hundreds were seen flying overhead or 

 in the distance. Thousands might be feeding in the riverain 

 pastures, while none were to be seen a mile or two away 

 where I was out collecting. The most detailed observation, 

 such as was not possible to me, would be required before any 

 accurate attempt could be made to give more detailed notes 

 of the different races than I have attempted. 



Motacilla flava borealis Sund. (4 skins.) 



This race of the Yellow Wagtail occurs on both spring (end 

 of March) and autumn passages (September), but it is 

 probably less abundant at the latter time. Two were seen 

 on 28 January, 1918, with a flock of M. alba. Three 

 specimens were preserved, in addition to a fourth doubtfully 

 attributed to this form. 



Motacilla flava melanogrisea (Homeyer). (5 skins.) 



The Black-headed Wagtail passes through the district in 



some numbers on both the spring passage (March) and the 



autumn passage (end of August to beginning of October).
