OSPHRANTER ANTILOPINUS, Gouwid. Red Wallaroo. Heap or a MALE, LIFE-SIZE, AND OF A FEMALE, REDUCED. Tux Red Wallaroo, of the Cobourg Peninsula, a noble species, second only in colour and structure to the Osphranter rufus, must for ever form a conspicuous object among the indi- genous quadrupeds of Australia. Its bare muffle at once mdicates it to be a less browzing animal than the Macropus major; while the structure of its feet and toes equally indicate that stony and rocky districts are the situations in which it is destined to dwell. Much disparity occurs in the size of the sexes, the female beg very much smaller than the male ; the accompanying illustration, however, does not portray the head of the female so large as it really is; on the other hand, the head of the adult male is the size of life. Fierce, bold, and even dangerous is this powerful animal. Its native rocks afford it partial pro- tection; but it is one of the species which will soon be extirpated when Northern Australia becomes peopled by miners or stockholders. The following Plate gives reduced figures of this fine species, and the accompanying letter- press a detailed account of its history and economy.
