SPIGGURUS MARTINI. (Nobis.)
SPIG. SPIGGURUS SPINOSA (FR. CUV.) HISTRIX SUBSPINOSUS. THE PORCUPINE.

This little animal is common in Brazil where it lives on trees and secures itself by means of its hind-feet, it uses its tail, which is pretty long, as a means of descending. Its length, from the muzzle to the tip of the tail, is about a foot; the tail is almost as long as the trunk. The upper parts of the body are covered with sharp prickles about an inch and a half long, and attached to the skin by means of a very thin pedicle. The head-prickles are white at the base, black in the middle and of a yellowish-brown at the top, the dorsal prickles are of a sulphur-yellow at their base. The prickles on the rump and the first third of the tail, are black at their extremity. All the prickles are very close together, mingled with a few long and fine hairs. The lower limbs are covered with a grayish fur, interspersed with little prickles; the tail is furnished with prickles at its upper part, and is covered with stiff and black hairs; the extremity of the tail is bare.

We triturate the prickles taken from one of the sides.
