The Southern Motacilla

MOTACILLA AUSTRALIS

M. cinera, subtus flava.

N.B. Gula fere albida.

Ash-coloured Motacilla, yellow beneath.

N.B. The throat inclines a little to whitish.

It is not perhaps absolutely clear whether this bird should be referred to the genus Motacilla, or Muscicapa: the probability, however, is in favour of Motacilla.

The bird is about the size of the Motacilla flava of Linnæus, or yellow wagtail, but seems of a stouter make. The beak is of a pale colour, and the legs brown. The two middle tail-feathers have the very extremities slightly marked with white.

The genus Motacilla is extremely numerous, and it is not easy to fix upon a proper or expressive trivial name. Such names should, if possible, convey some idea either of the colour or some other circumstance relative to the manners or habits of the animal; but in new species, whose history is unknown, this is impracticable. The trivial name, therefore, of Australis may be allowable, though it cannot be regarded as sufficiently distinctive.
