=Sylvilagus mansuetus=

Brush Rabbit

1907. _Sylvilagus mansuetus_ Nelson, Proc. Biol. Soc. Washington, 20:83, July 22, type from San Jose Island, Gulf of California, Baja California. Known from San Jose 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 pal.u.s.tris=

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 alt.i.tude, 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.
