ARMADILLO, a mail-clad mammal (order Edentata, fam ily Dasypodidae) closely allied to the sloths and ant-eaters. Its armour consists of a bony case, partly composed of solid buckler like plates, and partly of movable transverse bands. Armadillos are omnivorous, feeding on roots, insects, worms, reptiles and carrion, and are mostly nocturnal. They are harmless inoffensive creatures, their principal means of escape being the rapidity with which they burrow in the ground, and the tenacity with which they retain their hold in their subter ranean retreats. Notwithstanding the shortness of their limbs they run with rapidity. Most of the species are esteemed good eating by the natives. They are all in habitants of the tropical and tem perate parts of South America, though a few species range farther north, the nine-banded armadillo being found from Argen tina to southern Texas. The largest species is the giant armadillo (Priodon gigas), nearly a yard long, from Surinam and Brazil. For the distinctive characters of the genera see EDENTATA.
The name is revived in the title of Field-Marshal Lord Allenby of Megiddo (cr. 1919).
