In fact, the etymology of the family is enterobacterium with the suffix to designate a family ( aceae ) — not after the genus Enterobacter ( which would be " Enterobacteraceae ")— and the type genus is Escherichia.

Similarities between jackals and coyotes led Lorenz Oken, in 1816, in the third volume of his Lehrbuch der Naturgeschichte, to place these species into a new separate genus, Thos, after the classical Greek word " jackal ", but his theory had little immediate impact on taxonomy at the time.
