Jan. 1, 1845.--After a ride of about four miles down the creek, we came to a deep hole of good water, that had been filled by the late thunder-storms, the traces of which, however, had disappeared every where else. I found a red Passion flower, with three-lobed leaves, the lobes rounded: it was twining round the trunk of a gum tree, and rooted in a light sandy alluvial soil. A new species of Bauhinia, with large white blossoms, growing in small groves, or scattered in the scrub, particularly near the creeks, was conspicuous for its elegance, and was the greatest ornament of this part of the country. It is a tree about twenty-five feet high, with long drooping branches; the foliage is of a rich green colour, and affords a fine shade. A climbing Capparis, with broad lanceolate leaves, had also large white showy blossoms; and a fine specimen of this plant was seen growing in the fork of an old box tree, about twelve or fifteen feet from the ground; it was in fruit, but unfortunately was not yet ripe. There was also another species of the same genus, with yellow blossoms, in other respects very similar in appearance to the first. The white cedar was still abundant. When I returned to the camp, I found my companions busily engaged in straining the mud, which had remained in the water-hole after our horses and cattle had drunk and rolled in it. Messrs. Gilbert and Calvert had discovered a few quarts of water in the hollow stump of a tree; and Mr. Roper and Charley had driven the horses and cattle to another water-hole, about two miles off. Our latitude was 24 degrees 16 minutes 9 seconds. Jan. 2.--I moved my camp to the water-hole, near which I had met with the natives, and halted at the outside of a Bauhinia grove. On visiting the spot where the blacks were encamped, it appeared that they had returned and carried away all their things, probably well contented that we had not taken more than the turkey's egg. The mosquitoes were a little troublesome after sunset and in the early part of the night; but, after that time, it was too cold for them. The flies were a much greater nuisance; at times absolutely intolerable, from the pertinacity with which they clung to the corners of our eyes, to the lips, to the ears, and even to the sores on our fingers. The wind was generally from the eastward during the morning, with cumuli; but these disappeared in the afternoon. Brown found a crab, (a species of Gecarcinus?) the carapace about an inch and a quarter long, and one and a half broad, the left claws much larger than the right, the antepenultimate joint having a strong tooth on the upper side; it is found in moist places and in the lagoons, and, when these are dried up, it retires under logs and large stones. Mr. Gilbert saw a large grey wallabi, and a small one which he thought was new. Another species of Agama was found, differing from the former by its general grey colour, with black spots on the back.
