the coloration, and is more or less prominent on the neck and 

 shoulders. The nose, chin, and throat are soiled whitish, the 

 white extending back as a broad band along the sides of the 

 mouth and on the sides of the neck as far as the ear. 



The newly-born young are rufous, with a median dorsal 

 black stripe, from the occiput to the hips. The rufous of the 

 head and body is more or less varied with black, the individ- 

 ual hairs being in part wholly rufous and in part rufous 

 ringed or tipped with black. The nose, chin, and sides of the 

 face are uniform rufous-, like the body, showing none of the 

 whitish tint that has given to the adults the name White- 

 lipped Peccary. The rufous of the young in first pelage is 

 gradually replaced when the animal is about one fourth 

 grown by the black pelage of the adult. 



One of the most striking peculiarities of the subgenus Oli- 

 dosus appears hitherto to have escaped notice, namely, the 

 form and position of the audital bulla. In the subgenus 

 Tagassu the bulla is fully exposed posteriorly, and is sub- 

 triangular in outline, with a sharply convex antero-internal 

 angle, a slightly convex internal border, a short obliquely 

 truncated outer angle, and a broad oblique posterior face, 

 abruptly prolonged internally to form a swollen projection, 

 leaving a deeply concave surface on the posterior plane. In 

 Olidosus the posterior conical projection is greatly produced, 

 and the postero-external third (nearly one half in old specimens) 

 is covered and concealed by the downward projection of the 

 exoccipital, producing a very different outline for the exposed 

 portion of the bulla, which is greatly more extended posteriorly. 



"WILD HOGS. The two species distinguished here as 

 puerco [Tagassu pecari} and saina [Tagassu torvus] are both 

 common, especially in the dry forest near the coast; they 

 range certainly to 4000 feet, and probably higher. Puercos 

 go singly or (usually) in pairs, or the sow with her pigs; the 

 sainas commonly go in bands of four to ten. Both are eaten, 

 but the meat is unpleasant unless the scent gland is cut out 

 immediately after death. They are commonly hunted with 

 dogs and are often dangerous game, especially the sainas when 

 the bands are large. They wander both by day and night,
