Identification. This is the largest species of Sylvilagus Gray, 1867 in Chihuahua and the only one occurring in the highlands of the Sierra Madre Occidental. It is a large, heavy-bodied rabbit, with a gray-brown coat, and a conspicuous white tail. The belly hair is white ( Chapman et al. 1980 ; Lee et al. 2010 ).
Distribution. From southern Canada , through central, eastern USA and the Mexican highlands (pine, pine-oak forests) to Central America and northern South America ( Venezuela and Colombia ; Chapman et al. 1980 ). Recorded habitats in Chihuahua are sierras, valleys, and arid lands. Remarks. Two species of Sylvilagus have been recorded in Chihuahua ( López-González and García-Mendoza 2012 ): The Eastern Cottontail Rabbit and the Desert Cottontail Rabbit ( Sylvilagus audubonii (Baird, 1858)) ; the former inhabits forested areas (pine and pine-oak forests), and the latter inhabits grassland and desert areas.
