 appears somewhat similar. 



From 8. vagrans it differs in its chestnut brown color above, instead of olive brown, and the 

 less pure light color of the belly. Its fur is much shorter, the feet smaller, the skull is broader, 

 the ears considerably smaller. 



Several specimens of what I refer to this species, collected in more southern localities, differ 

 a little in color. They are considerably darker, more of a clove brown, with no chestnut tinge, 

 and there is a considerable admixture of hoary, caused by the fact that the extreme tips of the 

 hairs are darker than the penultimate portion.

SP. CH. Ears moderate, though distinct ; not half so long as the adjacent hairs. Fur very full, the longest hairs meas 

 uring over five lines. Feet and hands very stout and broad ; the latter contained about one and a half times in the former, 

 which are about two-thirds the length of the skull. Tail very thick throughout its whole length, with a decided pencil 

 at the tip ; about ieven-ninths the length of head and body ; longer than the body alone. Third lateral tooth above 

 larger than the fourth. No internal lobe to the anterior upper incisors, but these are somewhat widened and in contact 

 the rounded point. Premolars not imbricated.
