Unica per longitudinem stria in dentibus qui secant superioribus ; corpore

CHAEACTEES. 
A single longitudinal groove in the upper incisors ; body, rather smaller and 
less stout in form than P. bursarius ; cheek-pouches, smaller ; palms, much 
narrower ; tail, longer ; hair, coarser. Colour, above, brownish-yellow, beneath, 
gray. 
DESCEIPTION. 
The body of this species is a little smaller and more slender and elon- 
gated than that of P. bursarius ; head, small ; nose, long, and not so blunt 
as in that animal. The fore-foot (or hand) has the palm narrow, and less 
tuberculated beneath than in P. bursarius ; nails, narrower, a little longer, 
and much less arched than in that species ; and the cheek-pouches are 
smaller. Tail, long (double the length of tail of P. bursarius), and has a 
little tuft of hair around the base ; the rest of it, however, is naked. Feet, 
naked, instead of clothed with hair as in that animal. 
In the upper jaw the incisors are of moderate size, narrow, with a single 
groove in the centre, and no groove on the inner edges, as in P. bursarius. 
Septum, naked, with the nostrils entering in at the sides, immediately at 
the roots of the incisors ; whiskers, rising from the sides of the nose, short, 
thin, and sparse ; eyes, small, placed near each other in the head ; the ears 
exhibit a slight margin around the auditory opening ; they are placed far 
back, and not distant from each other ; toes, five on each foot : on the 
fore-feet the middle toe with the nail is much the longest ; the inner poste- 
rior toe is the smallest ; there are a few short rigid hairs on the inner 
edge of the palm, but the foot may be described as naked ; on the hind- 
foot, the claws, which are a little longer than those of P. bursarius, are 
hooked, and channelled beneath ; the hind-feet, to above the tarsus, are 
naked. 
The hairs on the body are short, the coat not being half the length of
