It includes the llama-like cameloids (Camelops) and a true camel (C americanus). The true prong-horn antelopes {An- tilocapra) make their first appearance here, and with them are associated the smaller Capr ornery x (C furcifer), an animal inter- mediate between the mery- codonts (see pp. 294-5, 357) and the true American prong-horns. The most abundant species of horse is E. complicatus, while E. fraternus, a smaller ani- mal, is also found. The sloth which appears here is distinct from the mid- Pleistocene Af^/Zorfon harlani of the East, and according to the determination of Brown belongs to a dis- tinct genus, Paramylodon} 1 Matthew, W.
