I mentioned that a herd of guanacoes was feeding near the shore when we arrived. Every exertion was made to obtain some of the animals; but, either from their shyness, or our ignorance of the mode of entrapping them, we tried in vain, until the arrival of a small sealing-vessel, which had hastened to our assistance, upon seeing the fires we had accidentally made, but which her crew thought were intended for signals of distress. They shot two, and sent some of the meat on board the Adventure. The next day, Mr. Tarn succeeded in shooting one, a female, which, when skinned and cleaned, weighed 168 lbs. Narborough mentions having killed one at Port San Julian, that weighed, "cleaned in his quarters, 268 lbs." The watchful and wary character of this animal is very remarkable. Whenever a herd is feeding, one is posted, like a sentinel, on a height; and, at the approach of danger, gives instant alarm by a loud neigh, when away they all go, at a hand-gallop, to the next eminence, where they quietly resume their feeding, {5} until again warned of the approach of danger by their vigilant 'look-out.' Another peculiarity of the guanaco is, the habit of resorting to particular spots for natural purposes. This is mentioned in the 'Dictionnaire d'Histoire Naturelle,' in the 'Encyclopédie Méthodique,' as well as other works. In one place we found the bones of thirty-one guanacoes collected within a space of thirty yards, perhaps the result of an encampment of Indians, as evident traces of them were observed; among which were a human jaw-bone, and a piece of agate ingeniously chipped into the shape of a spear-head. The fox, which we did not take, appeared to be small, and similar to a new species afterwards found by us in the Strait of Magalhaens. The cavia[5] (or, as it is called by Narborough, Byron, and Wood, the hare, an animal from which it differs both in appearance and habits, as well as flavour), makes a good dish; and so does the armadillo, which our people called the shell-pig.[6] This little animal is found abundantly about the low land, and lives in burrows underground; several were taken by the seamen, and, when cooked in their shells, were savoury and wholesome. Teal were abundant upon the marshy grounds. A few partridges, doves, and snipes, a rail, and some hawks were shot. The few sea-birds that were observed consisted of two species of gulls, a grebe and a penguin (_Aptenodytes Magellanica_). We found two species of snakes and several kinds of lizards. Fish were scarce, as were also insects; of the last, our {6} collections consisted only of a few species of _Coleoptera_, two or three _Lepidoptera_, and two _Hymenoptera_. Among the sea-shells, the most abundant was the _Patella deaurata_, Lamk.; this, with three other species of Patella, one _Chiton_, three species of _Mytilus_, three of _Murex_, one of _Crepidula_, and a _Venus_, were all that we collected.
