in 1868. Another "Antarctic wolf" arrived in 1870. Neither animal survived long. Only a dozen or so museum specimens exist today.

In 1880, after Falkland Islands wolf had become extinct, Thomas Huxley classified it as related to the coyote. In 1914, Oldfield Thomas moved it to the genus Dusicyon, with the culpeo and other South American foxes. (These other canids have since been removed to Lycalopex.)
