This hare is one of the largest of the lagomorphs. Its head and body length can range from 60 to 75 cm (24 to 30 in) with a tail length of 7.2 to 11 cm (2.8 to 4.3 in). The body mass is typically between 3 and 5 kg (6.6 and 11.0 lb).[20] The hare's elongated ears range from 9.4 to 11.0 cm (3.7 to 4.3 in) from the notch to tip. It also has long hind feet that have a length of between 14 and 16 cm (5.5 and 6.3 in).[21] The skull has nasal bones that are short, but broad and heavy. The supraorbital ridge has well-developed anterior and posterior lobes and the lacrimal bone projects prominently from the anterior wall of the orbit.[20]
