Halits and habitat. -ThougYi greatly reduced in number, peccaries 

 are still common in southwestern Texas. They prefer rocky walls o± 

 canyons and the vicinity of streams or hilltops where caverns and 

 hollows afford protection, to which they retire during midday. On 

 Las Moras Creek, in Kinney County, Texas, they often jom herds ot 

 domestic swine, feeding on roots, acorns, and pecan nuts in company 

 with the half-wild pigs known as " razor-backs."

Description. — The type, an old male, has the coloration paler than 

 that of the Texas peccary, Tayassu angulatum (Cope). Above there 

 is a mane of long, black-tipped bristles, the longest measuring 135 

 mm. in length, extending from the crown to the naked gland on 

 the rump, and producing by contrast a sharply black dorsal band. 

 The rest of the upper surface is a pepper-and-salt mixture of com- 

 mingled grayish white, yellowish white, and brownish black colors, 

 the bristles being whitish, ringed and pointed with brownish black. 

 On the flanks there is most whitish, while the shoulders are blackest 

 where the so-called " collar," a narrow band of buffy white, extends 

 across the side, behind the neck and in front of the shoulder, and is 

 bordered by blackish on either side. The muzzle, cheeks, and space 

 in front of the eye are brownish gray, annulated with darker. There 

 is a brownish white orbital area, and a spot of brown (glandular) 

 staining below the front of the eye. The under jaw is yellowish, 

 with a triangular blackish patch near the end of the chin. Ears with 

 outer (convex) surface and tip heavily coated with black bristles; 

 concavity with five bands of long, buffy, white hairs. (Fig. 7.) 

 Legs mixed brownish white and brownish black, becoming solid 

 black about the hoofs, and with a light band encircling the foreleg 

 above the accessory hoofs. Under surface of body with a blackish
