On reference to my account of the Centropus Phasianus, it will be seen I have stated that some variation exists in the form of the bill in specimens from different localities, intimated a belief of there being more than one species, and remarked that should such prove to be the case, the term macrourus might be applied to the Port Essington birds, and melanurus to those from the north-west coast; and these names are provisionally given until future research has proved whether they be or be not distinct.

Family CERTHIADÆ, Vig.
Genus Climacteris, Temm.
Several species of this well-defined and singular group of Australian birds have lately been discovered; two out of the six now known are all that had been described prior to the publication of the present work. With the exception of Van Diemen’s Land and the Cobourg Peninsula, every colony is inhabited by one or other of the following species:—
| 349. Climacteris scandens, Temm. | Vol. IV. Pl. 93. |
| 350. Climacteris rufa, Gould | Vol. IV. Pl. 94. |
| 351. Climacteris erythrops, Gould | Vol. IV. Pl. 95. |
| 352. Climacteris melanotus, Gould | Vol. IV. Pl. 96. |
| 353. Climacteris melanura, Gould | Vol. IV. Pl. 97. |
| 354. Climacteris picumnus, Temm. | Vol. IV. Pl. 98. |

Genus Orthonyx, Temm.
Much difference of opinion has arisen among ornithologists respecting the situation of this bird in the natural system, and as to what genus it is most nearly allied; I regret to say that not having seen much of it in its native wilds, I am unable to clear up these disputed points. The form is strictly Australian, and the single species known is confined to the south-eastern part of the country.
