Skull: medium-sized to large in all features except small in rostrum depth, short and narrow maxillary and mandibular toothrows, and shallow mandible, but with large auditory bullae. Color: grayish dorsally, pale ochraceous buff laterally, pale gray rump patch, and creamy white ventrally except for a dusky neck patch.
COMPARISONS.—For comparisons with S. f. macrocorpus see that subspecies. Sylvilagus f. holzneri differs from S. f. orizabae: externally, larger size and longer ear; cranially, larger skull particularly evident in greatest skull length and bullar length; and color, pale grayish dorsally rather than dark grayish.
