Marginal records (Nelson, 1909:245): María Madre Island; María Magdalena Island.
Total length, 480; tail, 51; hind foot, 99; ear from notch (dry), 57. This insular species is closely related to Sylvilagus cunicularius of the adjacent mainland but has notably shorter ears and more reddish on the upper parts, sides and legs; the skull is slenderer, especially in the rostral region. The posterior extensions of the supraorbital process are united to the braincase throughout most of their length as in Sylvilagus palustris. The species seems to have a narrow vertical range, occurring from sea level up to only 200 feet.

Total length, 363-664; tail, 25-112; hind foot, 112-189; ear from notch (dry), 62-144. Upper parts grayish, brownish or black; interparietal bone fused to surrounding bones; cervical vertabrae long, 2nd and 3rd being longer than wide; transverse processes of lumbar vertabrae long, the longest one equal to the length of the centrum to which it is attached plus half of the length of the preceding centrum; free extremity of transverse process of lumbar vertebra considerably expanded; distance from anterior edge of acetabulum to extreme anterior point of ilium less than distance from former point to most distant point of ischium; ulna reduced in size along middle part of shaft, and, excepting the lower extremity, placed almost entirely behind radius.
All members of the genus Lepus are technically hares, as these are defined in the account of the family Leporidae. The largest members of the order Lagomorpha are members of the genus Lepus. No domestic strains have been developed but effort in this direction might be profitable, in as much as the so-called Belgian hares of the related genus, Oryctolagus, have done well in captivity.
In the past it has been customary to recognize two or more subgenera of the genus Lepus. The species are a less diverse lot than those in some other genera, however, and it seems that no useful purpose is served by recognizing subgenera. Accordingly, the several names proposed for this purpose are arranged here as synonyms of the generic name Lepus Linnaeus.
The introduction of the European Hare (Lepus europaeus) into the eastern part of the North American Continent has been successful in the sense that the animal is multiplying. If it continues to increase, the increase almost certainly will be at the expense of some native species of rabbit. This circumstance and the unfortunate consequences of the introduction of the European rabbit (Oryctolagus cuniculus) in New Zealand (see Wodzicki, 1950:107-141) and Australia (see Stead, 1925:355-358) give basis for effort to exterminate the alien species before it spreads more widely.

California: Parker Creek, 6300 ft., Warner Mts. Nevada (Hall, 1946:600): 8600 ft., 3 mi. S Mt. Rose; 8900 ft., Lapon Canyon, Mt. Grant; Mt. Magruder. California (Orr, 1940:43): Tuolumne Meadows; Woodfords; Tahoe City; 4700 ft., Steele Meadows. Oregon: Antelope. Washington: Manson (Dalquest, 1948:382).
Total length, 465-630; tail, 50-112; hind foot, 112-145; ear from notch (dry), 99-131. Upper parts gray to blackish; tail with black mid-dorsal stripe extending onto back; never all white in winter. On the tableland of Mexico and in the southwestern United States where this species occurs together with the white-sided jack rabbits, L. californicus can be recognized by the terminal black patch on the outside of each ear and by the less extensive area of white on the flank. To the eastward, in Tamaulipas, where only the black-tailed jack rabbit occurs, it too, has extensively white flanks and some individuals lack the terminal black patch on the ear.
A certain means for distinguishing the skulls of the black-tailed jack rabbit from those of all of the white-sided jack rabbits has not yet been found. The same is true of the skulls of the white-tailed jack rabbit and the black-tailed jack rabbit in the Great Basin region of Nevada. The skulls, at least of adults, of these two species, in the region east of the Rocky Mountains can be readily distinguished by the pattern of infolding of the enamel on the front of the first upper incisor teeth; L. townsendii has a simple groove on the anterior face of the tooth and L. californicus, east of the Rocky Mountains, has a bifurcation, or even trifurcation, of the infold that can readily be seen by examining the occlusal surface of the incisor.
In Arizona, Vorhies and Taylor (1933:478) found the weight of 23 adult males to average 5.1 (4.4-6.1) lbs. In that state, 70 pregnant females averaged 2.24 (1-6) young per litter and the authors (op. cit.) thought that a female had three or four litters each year.
