\Vis*ca"cha\, Viz-cacha \Viz-ca"cha\, n. [Sp.]
(Zo["o]l.)
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}.
