    Rudimentary canines exist in the jaws of many deer, but it is clear that the common fallow-deer of the British parks, the roe-deer, and the Persian fallow-deer have none. The Hydropotes inermis, inhabiting the islands of the Yang-tse-kiang, is an aberrant antlerless member of the last family, and resembles the musk-deer in the remarkable length and strength of its maxillary canines. Other members of the CervidcB are the reindeer, and the elk or moose, the largest representative of all living deer, whose dental characteristics conform to the usual type. Fig. 318 Skull of a camel (Camelus dromedarius). X It is thus obvious that maxillary canines are generally absent in the deer, and are present in the musk deer, the Muntjac, the goat-like Chinese water deer, and the tufted deer. The Giraffe (Arabic zaraf—one who walks quickly) is indigenous to Africa, its long neck consisting only of seven vertebrae, as in the dissimilar hippopotamus, serves as a watch-tower, like that of the ostrich, which lives under like conditions. There are no maxillary incisors or canines; the premolars are brachyodont, a characteristic feature in the mandible being the length of the diastema—between the incisors and canines. The gregarious Pronghorn of Eastern, Central, and North America is regarded as a distinct family, from the fact that
