Characters.—Of relatively small size, this species is readily 
distinguished by its uniform coloration, which is generally 
blackish- or brownish-grey, with a tendency to a reddish or 
greyish phase in some specimens; the lower parts of the 
limbs being blackish. The body is long, the limbs short, and 
the tail much elongated, the head being also long and low. 
Blackish-grey at their bases, the hairs are black in the middt 
and greyish at their extremities. Female skins are reported to 
be lighter and brighter in colour than those of males. Pupil 
of eye circular when contracted. Skull elongated and flattened, 
with the nasal region very strongly compressed. Length of 
head and body, about 30 inches; of tail, 25 inches. 
Distribution.— Brazil, Paraguay, Guiana, to North-eastern 
Mexico.

adults, that the sexes only differed in the male being rather the
