. The tail is also well haired along its entire length, with individual hairs extending over more than three scale rows. Although partially hidden from view by hairs, the tail scales appear rather coarse, and average 11 rows per cm. The dorsal pelage varies from grayish to orangish brown in color; it is thick and somewhat woolly in texture. The ventral pelage is graybased throughout in all specimens, with either offwhite or pale buffy tips;

As limited as these data are, they do suggest that breeding is delayed in this species relative to other sympatric sigmodontines. This may account, at least in part, for the relative rarity of these rats.
