The hind-foot always has five digits with smaller claws. The tail is usually well Fig. 321. —Tatu armadillo (Dasypus sexcinctus). (After Vogt and Specht.) The most striking external feature of the armadillos is the presence of an armour of bony dermal plates. This usually consists of a scapular shield of closely united plates covering the anterior part of the body, followed by a series of trans- verse bands separated from one another by hairy skin, and a posterior pelvic shield. The tail is also usually enclosed in rings of bony plates, and a number protect the upper surface of the head. Dasypus occurs in southwestern Texas. In the scaly ant-eaters (Manis) (Fig. 322) the head is produced into a short pointed muzzle. The limbs are short.
