=Sylvilagus bachmani=

Brush Rabbit

Size small. Total length, 300-375; tail, 20-43; hind foot, 64-81; ear from notch (dry), 50-64; weight (topotypes of _S. b. macrorhinus_) 16 [MALE] 679 (561-832), 22 [FEMALE] 707 (517-843) grams. Body uniformly dark brown or brownish gray, but tail whitish beneath; hair on midventral part of body gray at base; only a slight crenulation of ridge of enamel which separates an individual molariform tooth into anterior and posterior sections. From _Sylvilagus audubonii_, the only other species of _Sylvilagus_ in the same geographic area, _S. bachmani_ differs in smaller size, less white on underparts (the hairs on the midventral part of the body being gray instead of white at base), shorter ears and legs, and a less crenulated ridge of enamel separating the anterior and posterior parts of a molariform tooth.

The brush rabbit is a Pacific Coastal species; as may be seen from figure 9 on the next page, this species occurs from the Columbia River on the north to the tip of Baja California on the south. Nowhere, so far as I can learn, does it occur as far east as the crest of the Cascade-Sierra Nevada Mountain Chain. Throughout its range the brush rabbit is closely associated with--in fact, lives in--the chaparral that is dense enough to afford protection from raptorial birds and the larger carnivorous mammals. The rabbit's reliance on protective cover is so great that, as pointed out on an earlier page, a person can turn this trait to advantage in protecting cultivated crops from inroads that the rabbits might make on them. The protection is afforded by clearing the brush from a strip forty-five feet wide so that the cleared strip intervenes between the cultivated crops and the brushy shelter. The rabbits will not risk crossing the open strip and hence do not reach the growing crops.

Brush rabbits use simple "forms" in the brush for resting. Only one observer (Orr, 1940: 173) has reported an individual entering a hole. In patches of chaparral in which the rabbits live they make runways that are especially well defined at the edges of the brush. The outer entrance to a runway is tunnellike and one to two feet from the outer entrance there is a special form that serves as a lookout post. A brush rabbit that is about to venture into the open ordinarily pauses in such a form for several minutes, presumably to satisfy itself that no enemy is in the open area whither the rabbit is bound.

The breeding season is from January to June, at least in California. There are 2 to 5 young, averaging 3.5 per litter. They are born in a nest.

=Sylvilagus mansuetus=

Brush Rabbit

1907. _Sylvilagus mansuetus_ Nelson, Proc. Biol. Soc. Washington, 20:83, July 22, type from San Jos['e] Island, Gulf of California, Baja California. Known from San Jos['e] Island only.

This insular species is closely related to _Sylvilagus bachmani_ and is distinguished by paleness, proportionately longer and narrower skull, fusion to skull of anterior arm of supraorbital process, and larger jugal.

=Sylvilagus palustris=

Marsh Rabbit

(See figure 42)

Total length, 425-440; tail, 33-39; hind foot, 88-91; ear from notch (dry), 45-52. Upper parts blackish brown or reddish brown; underside of tail brownish or dingy gray (not white); ears, tail and hind feet short; posterior and anterior extensions of supraorbital processes joined to skull along most (or all) of their extent. The lack of white on the underside of the tail is a ready means of distinguishing this species from the other species of the genus which occur within its geographic range. The species occurs in the lowlands, possibly not above 500 feet altitude, of the Lower Austral and Tropical life-zones. In Florida, Blair (1936) found that the marsh rabbit ate 29 per cent of its bodily weight in green food each day and that the number of embryos in 3 females was 4, 4 and 3.

=Sylvilagus floridanus=

Florida Cottontail

Total length, 375-463; tail, 39-65; hind foot, 87-104; ear from notch (dry), 49-68; upper parts brownish or grayish; underside of tail white; skull with transversely thick posterior extension of supraorbital process of frontal. The geographic range is the largest of all of the North American species of the genus _Sylvilagus_; from Canada the species occurs south at least to Costa Rica and it may occur in Panam['a] for the species is recorded also from South America.

In the western part of the Great Plains this species is confined to the riparian growth along streams and _Sylvilagus audubonii_ occupies the remainder of the terrain. In New Mexico and southwestern Texas _S. floridanus_ is confined to the boreal life-zones where timber provides denser cover than is found in the lower life-zones. The zonal range is from the Canadian Life-zone into the Tropical Life-zone. It is not surprising, therefore, that there is much geographic variation in the shape and size of the skull. There is so much geographic variation in the skull that it is impossible, at this writing at least, to frame a description that will enable the reader to distinguish the skull from those of all other species of the genus. In any given area, however, it is possible, easily and certainly, to distinguish the skulls of _S. floridanus_ from those of the other species which occur in that area.
