Colour uniform bright brownish yellow somewhat less bright towards the head, and becoming darker towards the middle of the tail. The mutilated tail measures four inches, and appears to have been twice that length when perfect. The ears seem to have been small; claws of proportionate strength. in. lin.

The molar series diverge very slightly in front. Molar teeth distinctly longer than wide, with internal enamel-fold deeply penetrating the tooth and sometimes crossing it without interruption. The palatal notch advances to the level of the middle of the third molar. Vertical occipital crest developed. millim.
