THE SOUTHERN MOTACILLA. 
MOTACILLA AUSTRALIS. 
M. cinera, fubtus jlava. 
N. B. Gula fere albida. 
Afli-coloured Motacilla, yellow beneath. 
N. B. The throat inclines a little to whitifli. 
It is not perhaps abfolutely clear whether this bird fhould 
be referred to the genus Motacilla, or Mufcicapa : the pro- 
bability, however, is in favour of Motacilla. 
The bird is about the fize of the Motacilla flava of Lin- 
naeus, or yellow wagtail, but feems of a flouter make. 
The beak is of a pale colour, and the legs brown. The 
two middle tail-feathers have the very extremities flightly 
marked with white. 
The genus Motacilla is extremely numerous, and it is not 
eafy to fix upon a proper or expreflive trivial name. Such 
names fhould, if pofTible, convey fome idea either of the 
colour, or fome other circumftance relative to the manners 
or habits of the animal ; but in new fpecies, whofe hiftory 
is unknown, this is impradicable. The trivial name, there- 
fore, of Auftralis may be allowable, though it cannot be re- 
garded as fufficiently diftindtive.
