Eastern cottontail Sylvilagus floridanus, photographed by Doyle Frank.

Belongs within: Lagomorpha.
Contains: Oryctolagini.

The Leporidae includes the rabbits and hares, small to medium-sized herbivorous mammals with generally elongate ears and feet. Among the larger genera of leporids is Sylvilagus, the cottontails, an assemblage of burrowing rabbits found in North and northern South America.

Synapomorphies (from Averianov 1999, for crown-group excluding Hypolagus): P2 with three or more reentrants; M3 reduced, width <40% of width of M2; p3 with both posteroexternal and posterointernal reentrants present.
