The distinctive markings are, on the former species a greyish-white patch along the jaws, and on the other a yellowish-white belt, embracing the neck and shoulders, as a collar does a horse. These markings have given to each its specific name. They are farther distinguished, by the forehead of the white-lipped peccary being more hollowed or concave than that of its congener. In most other respects these creatures are alike. Both feed upon roots, fruits, frogs, toads, lizards, and snakes. Both make their lair in hollow logs, or in caves among the rocks, and both are gregarious in their habits. In this last habit, however, they exhibit some difference. The white-lipped species associate in troops to the number of hundreds, and even as many as a thousand have been seen together; whereas the others do not live in such large droves, but are oftener met with in pairs. Yet this difference of habit may arise from the fact that in the places where both have been observed, the latter have not been so plentiful as the white-lipped species. As many as a hundred of the collared peccary have been observed in one "gang," and no doubt had there been more of them in the neighbourhood, the flock would have been still larger. The white-lipped species does not extend to the northern half of the American Continent. Its _habitat_ is in the great tropical forests of Guyana and Brazil, and it is found much farther south, being common in Paraguay. It is there known as the "vaquira," whence our word "peccary." The other species is also found in South America, and is distinguished as the "vaquira de collar" (collared peccary). Of course, they both have trivial Indian names, differing in different parts of the country. The former is called in Paraguay "Tagnicati," while the latter is the "Taytetou." Neither species is so numerous as they were informer times. They have been thinned off by hunting--not for the value either of their flesh or their skins, not for the mere sport either, but on account of their destructive habits. In the neighbourhood of settlements they make frequent forays into the maize and mandioc fields, and they will lay waste a plantation of sugar-cane in a single night. For this reason it is that a war of extermination has long been waged against them by the planters and their dependents.
