Creator Gould's Mammals of Australia (1845-1863)

Date 1863

The common wallaroo (Osphranter robustus), also known as the euro, hill wallaroo, or simply wallaroo, is extant across most of Australia...Calling it a 'Black Wallaroo' Gould wrote:.'If there be any one of the Great Kangaroos the discovery of which afforded me more pleasure than another during my sojourn in Australia, it is the Great Black Wallaroo of the mountain districts of New South Wales. Surprising, indeed, it was that so large and conspicuous an animal had not been previously made known; and stil more suprising is the fact that, form the period of my visit in 1838-39 to the present time, 1863, few if any skins of the animal have been sent to Europe. Still I can assure my readers that the existence of the Black Wallaroo is not a myth.'
