[Ill.u.s.tration: FIG. 40. Distribution of _Sylvilagus transitionalis_.]

Total length, 388; tail, 39; hind foot, 95; ear from notch (dry), 52.

Upper parts almost pinkish buff, varying to almost ochraceous buff; back overlaid by a distinct black wash giving a penciled effect; anterior extension of supraorbital process obsolete or short and closely appressed to orbital rim; tympanic bullae small, smaller than in any subspecies of _S. florida.n.u.s_ in the United States. _S. transitionalis_ is a forest-inhabiting species--more so than is _S. florida.n.u.s_.

=Sylvilagus nuttallii=

Nuttall Cottontail

(See figure 39)

Total length, 350-390; tail, 44-50; hind foot, 88-100; ear from notch (dry), 55-56; weight in Nevada, ? 678, 3 ? 928 (868-1032) grams. Hind feet densely covered with long hair; ear short; tympanic bulla of moderate size. In the northern part of its range _S. nuttallii_ occurs princ.i.p.ally in the sagebrush areas but it occurs also in the timbered areas of the Transition Life-zone and almost exclusively in timbered areas in the southern part of its range. From _S. florida.n.u.s_, _S.

nuttallii_ along the eastern margin of its range differs in more slender rostrum, and larger external auditory meatus. In New Mexico and Arizona, _S. nuttallii_ differs from _S. florida.n.u.s_ in the posteriorly pointed and un-notched supraoccipital shield and in the posterior extension of the supraorbital process, the tip of which projects free from the braincase or merely lies against the braincase instead of being firmly welded to the side of the skull. From _S. audubonii_, _S. nuttallii_ differs in shorter ears, smaller tympanic bullae and smaller hind legs; _S. nuttallii_ usually occurs at higher elevations, or where the two occur at approximately the same elevation _S. nuttallii_ occurs in wooded or brushy areas and _S. audubonii_ lives on the plains or in relatively open country. Eight females contained an average of 6.1 (4-8) embryos.
