The first representative of the Rhinoceros family is the Orthocynodon, an animal with large upright canines, discovered in the Upper Eocene strata of the United States. Tlie fossil Rhinoceroses properly so called are first found in the Miocene, and are divided into four groups. The first group is characterised by the nostrils being separated by a bony partition, and in the adult animal the incisor teeth are lost: the second is distinguished by the absence of a bony partition between the nostrils, and the incisor teeth are of a medium size: in the third there is no partition, but the incisors are large ; and in the fourth it is imperfectly developed. An example of the first group, and probably the best known form of all the extinct Rhinoceroses, is Rhinoceros tichorhinus, or the Woolly Rhinoceros. Like that of the Mammoth, with which animal it was evidently associated, its entire body was covered with hair and wool, the skin had no folds, and its nose carried two horns, the anterior of which was of remarkable size, and characteristic of the group to which it belongs ; the nostrils were separated by a complete bony partition. The Woolly Rhinoceros has Ijeen discovered under similar circumstances to that of the Mammoth, having been found embedded in i.'; in the northern latitudes of Asia, in the years 1771 or 1772, being some twenty years previous to that of the discover
