These the mother promptly devoured, and she died three days later. This specimen (see PI. IV.), as preserved in formol, is 14 inches in length, exclusive of the tail, which measures about 13 inches in length. The body and head are covered with sparse coarse hair, which is reddish ferruginous from the eyes to the shoulders and dusky brown on the rest of the body. The hair becomes very thin and scattered on the hind-quarters, which for some distance on the back and sides are naked, roughly corrugated, and warty, with a sparse, short, woolly growth between the excrescences. The legs, snout, and eyelids are naked, and, with the bare skin of the rump, are pinkish white. The ears are short, thin, rounded, and are bluish grey witli light edges.
