1911 Encyclopædia Britannica/Kit-fox

KIT-FOX (Canis [Vulpes] velox), a small fox, from north-western America, measuring less than a yard in length, with a tail of nearly a third this length. There is a good deal of variation in the colour of the fur, the prevailing tint being grey. A specimen in the Zoological Gardens of London had the back and tail dark grey, the tail tipped with black, and a rufous wash on the cheeks, shoulders, flanks and outer surface of the limbs, with the under surface white. The specific name was given on account of the extraordinary swiftness of the animal. (See Carnivora.)
