FIG. 187.—Three species of jack rabbits differing in size, color, and markings, but believed to be derived from one stock. The differences have arisen through isolation and adaptation. The upper figure shows the head and fore legs of the black jack rabbit, Lepus insulariis, of Espiritu Sanctu Island, Gulf of California; the lower right-hand figure the Arizona jack rabbit, Lepus alleni, specimen from Fort Lowell, Arizona; and the lower left-hand figure the San Pedro Martin jack rabbit, Lepus martirensis, from San Pedro Martin, Baja California.
