As already remarked, this species is externally very similar to the 8. cooperi, and the imper- 
fection of the specimen renders it still more difficult to distinguish. The shape of the skull 
and teeth will, however, furnish ready grounds for separating the two—better, indeed, than in 
many cases where the differences of external form are more striking. The size appears some- 
what larger, and the tail shorter, though this may be owing to imperfect stuffing. The feet 
are rather smaller, and the three central toes not so much elangated ; consequently the first and 
fifth claws extend further along the adjacent toes, reaching the penultimate articulation, instead 
of falling short of it. The soles are apparently without the two large tubercles on each edge, 
and are more covered by hair. The color is much the same, although there is a slightly hoary 
appearance in the present species not found in the other. The ears appear much the same. As 
stated, however, in this species, the skull is very decidedly fuller in the region of the cranium, 
as well as higher and broader anteriorly, less attenuated every way ; the longitudinal axis of 
the skull and of the palate both shorter, and the palate wider. The third lateral upper tooth is 
smaller than the fourth, instead of being equal to it, and the fourth tooth is larger than in its 
analogues in the other species. 
The characters of this species are perhaps more like those ot §. personatus ; the size is, how-
