"Lycalopex" is a South American genus of canine distantly related to wolves and is technically not a fox. When Charles Darwin collected a specimen from San Pedro Island in Chiloé Archipelago in December 1834 during the "Beagle" survey expedition, he observed that this "fox (of Chiloe, a rare animal) sat on the point &amp; was so absorbed in watching [survey work], that he allowed me to walk behind him &amp; actually kill him with my geological hammer". In the 1839 publication of his "Journal and Remarks", Darwin said "This fox, more curious or more scientific, but less wise, than the generality of his brethren, is now mounted in the museum of the Zoological Society." He said it was "an undescribed species", indicating that it was distinct from the species ("L. culpaeus" and "L. griseus") that occur on the mainland. Later, Darwin's fox was classified as a subspecies ("Lycalopex griseus fulvipes") of the latter.
