THE AFRICAN PORCUPINE.

Hystrix Cristata. Linn.

Although the Rodent order, next to the Carnivorous, is the most numerous in species, the Porcupine is the only animal belonging to it which is at present contained in the Menagerie. The animals of this division, consisting chiefly of “rats and mice and such small deer,” have indeed, with some few exceptions, so little of interest for the mere casual visiter of an exhibition, that it is rarely that they are sought after unless by the scientific collector. They are at once distinguished from the Carnivora by the total absence of canine teeth; and have uniformly two incisors in each jaw, projecting forwards and generally of considerable size, separated from a variable number of grinders by a vacant space.

From the other animals of the order the Porcupines[162] are so readily distinguished by the long and pointed spines with which their body is armed, that it is unnecessary to dwell on their generic characters. The common Porcupine, when fully grown, as in the remarkably fine specimen figured over leaf, measures more than two feet from the tip of the nose to the origin of the tail. The spines, which are supported by a slender pedicel, thickly clothe the upper and posterior parts of the body, the largest being more than a foot in length; they are regularly surrounded by alternate rings of black and white. The head and neck are crested with long, bristly, black hairs, forming a kind of mane, and all the rest of the body is covered with short black hair.

The Porcupine is a native of Africa and the south of Europe; he chooses for his abode the most arid and solitary situations, and passes the daytime secluded in the burrows which he digs for his habitation, quitting them only at night to provide his subsistence, which consists entirely of vegetable substances. He is a remarkably timid animal, and never makes use of his formidable weapons except in self-defence; if alarmed, his spines immediately become erected, and woe be to the enemy who should dare to attack him open-mouthed when in that posture.
