THE PKONG-HOBNED ANTELOPE 117 135° 50 30 When fighting, or alarmed, this white hair is instantly thrown up, and on a fleeing animal it forms a dangerously conspicuous and inviting mark. To my mind, the white rump-patch of the Prong-Horn is one of Nature's errors. It enables a pursuer to mark the animal long after it should really become invisible. The Prong-Horned Antelope is next in size to the smaller species of our mountain sheep. It is smaller than the white-tailed deer of the north, but as large as the southern forms. The largest specimen in the Zoological Park herd measures 37-j inches high at the shoulders, has a head and body length of 47J inches, tail, 3$ inches, and chest circumference of 35 inches. Its horns are 12-J- inches long and 12\ inches wide be- tween the tips. The longest horns on record are 17 inches in length, but any that meas- ure 12 inches may fairly be considered large. The female has no horns. The colors of this animal are usually two, consisting of a cloak of light yellowish- brown thrown over the back and neck of an otherwise white animal. On the throat the brown is laid on in a curious collar-like pattern, and the adult males usually have a wash of black on their cheeks. The ears are very shapely, and from the neck an erect mane rises from four to five inches in length. The legs are exceedingly trim and delicately formed, and the erect horns and high pose of the head give the animal a very jaunty appearance. In running it has three very distinct gaits. When fleeing from danger, it carries its head low, like a running sheep, and gallops by long leaps; when showing off, it holds its head as high as possible, and trots forward with stiff legs, and long strides, like German soldiers doing the goose- step. Occasionally, it gallops with high head, by stiff-legged leaps, like the mule deer. In captivity the Prong-Horn is
