We could perceive no traces either of remains of fires, or otherwise of natives, in the whole length of our walk along the edge of the cliffs or the plains, but we saw two snakes of very distinct kinds, each exceeding five feet in length; the one black with a yellow belly, the other green and black, but they quickly escaped into holes, leaving a serpentine impression of their bodies upon the sand.

These marks were seen and remarked near the edge of all the holes, which were very numerous upon the surface of the island, before I discovered that they were the tracks of reptiles, from which it may be inferred that these animals are very abundant.

The only bird seen was a solitary species of loxia, but upon a steep ledge of rocks I observed one of those nests of which frequent mention has been already made: I examined and found it built upon the pinnacle of some large rocks, very strongly constructed of long sticks; it was about five feet high and exceeded four feet in diameter, with a very slight cavity above; and seemed to have been very recently inhabited.

The rocks that formed its base were ornamented with a prostrate capparis, or calyptranthus (Calyptranthus orbicularis, Cunningham manuscript) which afforded me good flowering specimens.

In my walk I started a small black kangaroo: it was feeding upon the seeds of a small acacia and, upon perceiving my approach, fled across the down without reaching a single bush or rock large enough to conceal itself as far as the eye could discern it, so bare and destitute of vegetation are these arid, sandy plains."* The heat of the weather was so great as not to allow of any communication with the shore, excepting between daybreak and eight o'clock.
