Two species at least of this genus are known, one inhabiting Europe and India and the other Australia: both have the irides white.
| 554. Nyroca Australis, Gould | Vol. VII. Pl. 16. |
Genus Erismatura, Bonap.
The members of this genus, although but few in number, are found in Europe, Asia, Africa, America and Australia.
| 555. Erismatura Australis | Vol. VII. Pl. 17. |
This species, the only one of the genus inhabiting Australia, is, I believe, strictly confined to the western parts of the country, as hitherto it has not been seen elsewhere.
Genus Biziura, Leach.
A genus of which only a single species is known to exist, and which is singularly different from every other member of the family. It is strictly Australian, and may be regarded as one of the anomalies of its fauna.
| 556. Biziura lobata | Vol. VII. Pl. 18. |
