Genus Anas, Linn.
Of true Ducks three species are found in Australia.
| 547. Anas superciliosa, Gmel. | Vol. VII. Pl. 9. |
This bird assimilates very closely in its structure and in its economy to the Anas Boschas of Europe, but in its plumage it is very different.
| 548. Anas nævosa, Gould | Vol. VII. Pl. 10. |
A very singular Duck, perhaps more nearly allied to Chaulelasmus than to Anas. It is a very rare bird, and has only yet been seen on the western and southern coasts of Australia; its true habitat is probably the distant interior.
| 549. Anas punctata, Cuv. | Vol. VII. Pl. 11. |
This species has much the appearance of the Teal (genus Querquedula), but in its structure is nearly allied to the true ducks (genus Anas), with which I have provisionally placed it.
Genus Spatula, Boie.
The great continents of America, Africa, Asia and Australia, are each inhabited by one or more species of this restricted genus.
