- A large burrowing South American rodent (Lagostomus
trichodactylus) allied to the chinchillas, but much larger. Its fur is
soft and rather long, mottled gray above, white or yellowish white
beneath. There is a white band across the muzzle, and a dark band on
each cheek. It inhabits grassy plains, and is noted for its extensive
burrows and for heaping up miscellaneous articles at the mouth of its
burrows. Called also biscacha, bizcacha, vischacha, vishatscha.
