of Dicotyles. When the animal is killed for food, it is necessary 
speedily to remove this gland, otherwise it will taint the whole 
flesh so as to render it uneatable. 
There are two species,! so nearly allied that they will breed 
together freely in captivity. Unlike the true Pigs, they never 
appear to produce more than two young ones at a birth. The

Generally it is found singly or in pairs, or at most in small herds of 
from eight to ten, and is a comparatively harmless creature, not being 
inclined to attack other animals or human beings. Its colour is dark 
gray, with a white or whitish band passing across the chest from 
shoulder to shoulder. The length of the head and body is about 
36 inches. The White-lipped Peccary or Warree (D. labiatus, Cuvier) 
is rather larger, being about 40 inches in length, of a blackish 
colour, with the lips and lower jaw white. Its range is less ex- 
tensive, since it is not found farther north than British Honduras 
or south of Paraguay. It is generally met with in large herds of 
from fifty to a hundred or more individuals, and is of a more 
pugnacious disposition than the former species, and capable of
