(*Footnote. An undescribed species of Cancriform epeira, belonging to the subgenus Gasteracantha of M. Hahn.) REDUCED STATE OF THE RIVER. The general course of the Gwydir appeared to be nearly westward, between the first and last points thus ascertained by us; and this direction being also in continuation of the river seen so much further to the eastward by Mr. Cunningham we could entertain no doubt as to the identity. The channels we had crossed before we came to the running stream at our present encampment could only be accounted for as separate ducts for the swollen waters of the river when no longer confined by any immediate high ground to one great channel; and hence the attenuated state (as we inferred) of the actual bed of the stream. This I resolved to trace through one day's journey, and then to cross, if we found no change, and so proceed northward. January 19. We travelled as the dense line of river-wood permitted for eleven miles; the ground outside this belt being in general open and firmer than that nearer the river, which was distinguished by certain inequalities, and was besides rather thickly wooded. We found that on a bearing of 20 degrees south of west we just cleared the southern bends of the stream. We heard the natives in the woods during our journey but none approached the party. In order to encamp we directed our course northward, and making the riverbank after travelling one mile, we encamped upon it. I then sent Mr. White due north in order to ascertain if any other channel existed, but he found, on the contrary, that the ground rose gradually beyond the river, which convinced me that this, in which the water flowed, was the most northerly channel. The latitude was 29 degrees 31 minutes 49 seconds South. January 20. I gave the party a day's repose that I might put my map together and duly consider the general course of the waters as they appeared thereon, and also the actual character of the stream on which we were encamped. The banks consisted of soft earth, having a uniform slope, and they were marked with various horizontal lines, probably denoting the height which the water had attained during different floods. The river had a peculiar uniformity of width and would therefore but for the tortuous course, have resembled a canal. The width was small in proportion to the depth, and both were greatest at the sharp bends of the channel. The water was of a white clay colour. The ground to the distance of half a mile from each bank was broken and furrowed into grassy hollows resembling old channels; so that the slightest appearance of such inequality was a sure indication of the river being near while we travelled parallel to its course. The whole of the country beyond was so level that the slightest appearance of a hollow was a most welcome sight as it relieved us from any despair of finding water.
