a grunting animal allied to the swine. An adult is about three feet long. Peccaries live in herds in a grassy cover, feeding on roots, nuts, and potatoes. The planters in the forest regions of South and Central America dread the invasion of a herd, especially as they are given to raiding at night. The flesh may be eaten, but white people prefer to leave it to the natives. There are two species, the collared and the white-lipped. The former ranges as far north as the bottoms of the Red River in Arkansas. It is a plucky animal of the chase in Mexico and Texas, and an enraged drove will drive a hunter up a tree.

The collared peccary (Dicotyles torquatus) PECCARY ranges from Arkansas S. to the Rio Negro, and seldom attacks other animals. The white-lipped peccary (D. labiatus) is rarely met with N. of British Honduras or S. of Paraguay. It associates in large droves, is very pugnacious, and does not hesitate to attack man. Both are omnivorous, and possess a gland in the middle of the back, secreting a musky substance, which taints the meat if not speedily removed after death.
