Genus XV. ACCENTOR. 
1. A. modularis (Hedge Warbler). 
Genus XVI. MOTACILLA. 
1. M. alba (White Wagtail). 
2. M. Boarurula (Gray Wagtail). 
The Gray Wagtail is by no means uncommon in the autumn 
and winter season in the low meadows by the river Gipping in 
Suffolk, and likewise in the neighbourhood of Higham. It is 
also frequently met with in Norfolk at the same seasons. lt 
runs upon the tops of the weeds, which are partly submerged in 
the ditches, and probably feeds upon the Dytisci and Gyrini, 
which are almost always to be found in those situations. 
3. M. flava (Yellow Wagtail). 
This species is not generally plentiful in Suffolk, though it is 
pretty common on parts of the river Waveney, which divides that 
county from Norfolk. ! 
Genus XVII. ANTHUS. 
1. À. pratensis (Tit Lark). 
2. A. arboreus (Field Lark). 
A common species in the neighbourhood of Harleston during 
the summer ; and it is also found in various parts both of Norfolk 
and Suffolk. This bird is subject not only to an Hippobosca, 
but likewise to a large species of Acarus. Five of these insects 
were taken off the head of a lark on the first day of its arrival.
