According to Mr.Gilbert, rock wallabies were very numerous.

On a RECONNOISSANCE I traversed the continuation of the range, which I found to be of a flat, sandy, and rotten character, having, with the exception of the Blackbutt, all the trees and other characteristics of the sandstone country of Moreton Bay: Xylomelum, Xanthorrhaea, Zamia, Leptospermum, a new species of forest oak, which deserves the name of Casuarina VILLOSA, for its bark looks quite villous; Persoonia falcata, R.Br., a small tree about fifteen feet high, with stiff glaucous falcate leaves, and racemose inflorescence; a dwarf Persoonia, with linear leaves, the stringy-bark, and a species of Melaleuca along the creek.

In my excursion I crossed the main branch of Robinson's Creek, and found the gullies of its right bank as steep and tremendous as those of the left.

Water was very scarce.

The whole country is composed of a fine-grained sandstone.
As the water-holes on the range are very few and distant from each other, they are frequented by the bronze-winged pigeons in great numbers.
