deep bay or reddish-brown hue, and delicate hairs of the same

[Figure: Skull of _Harpiocephalus harpia_.]

This bat is, for its size, one of the most powerfully armed with teeth.
The skull reminds one of that of a dog or hyaena in miniature; the
teeth are very stout, the canines blunt and conical, and the cusps
of the molars short and blunt, well coated with enamel; the jaws are
correspondingly muscular and adapted to the food of the animal, which
consists of hard-shelled beetles, the crushed cases of which have
been found in its stomach.

clad; the fur on the back is black, with bright golden yellow tips;
the back of the fore-arm covered with short golden hair; the hair
