Show 498 DR. J. E. GRAY ON THE ROEBUCK OF PERU. [Nov. 1 1, middle of the back some of the dark fur of the animal sent by the Earl of Derby, which I described. As stated in m y paper, this animal chiefly differs from the Roebuck of Europe in being without any glandular tufts on the outer side of the metatarsus ; but we now discover that the horns are very peculiar, and unlike those of the Roebuck, or of the Tarush or Roebuck of Bolivia (Furcifer antisiensis), which is the type of the genus Furcifer. The male now obtained had a well-developed but rather unsymmetrical pair of horns, which are so unlike the horns of any other Deer, that I propose to form for them a genus, which may be termed XENELAPHUS. The horns divide from the base into two branches; the front one is erect, conical, and acute, with a short conical branch on the outer side, and in the middle one or two more or less elongate, basal anterior or interior snags. The hinder part of the base and sheath compressed, diverging horizontally into a strong, angular, tapering branch, which is nearly as long as the erect one, with several irregularly placed, more or less elongate, acute processes; the upper part, near the roots, with one or two cylindrical diverging branches on its upper and lower sides. Like the small branches on the erect part of the horn, they are not exactly similar on the two horns. Fig. 2. Skull of Xenelaphus huamel, <j? . The metatarsus is without any glandular tuft on the outside. On the inner side of the hock is a large rounded tuft of such hairs. The fur consists of thick, elastic, tubular quills. The skull has a well-marked, deep, triangular pit in the front of the orbit. The female * is without horns. This animal may be called Xenelaphus huamel. It has been suggested that, as I have only seen one specimen of |
