Ricardo Pliocene, Mohave Desert, California. In no. 21197 (fig. 196) the prox- imal phalangeal element is shorter and much less slender than in no. 21200. It is also larger than in any of the forms like Protohippus or Meryehippus from the Barstow beds, and is relatively wider than the Barstow forms. This element is nearer the form of the corre- sponding element in Hypohippus, but is longer and more slender than any proximal phalanx of Hypohippus known to the writer, and much more slender than ele- ments from the Barstow fauna which are apparently to be re- ferred to Hypohippus (see figs. 29, 30). This element is near the form of the proximal phalanx in Hip- parion theoboldi of the Siwalik beds, but is more slender and smaller than in H. theoboldi. Several metapodials represent a species much larger than any form from the Barstow. A second and somewhat smaller form is possibly represented by a single specimen, no. 21201. The distal end of a 202), represents a form possibly single metapodial, no. 21478 (fig. larger and distinct from the others. In the more common form the shaft of metapodial III is consider- ably larger than in any specimen from the Barstow beds, and is much heavier than in the average Meryehippus or Protohippus Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original University of California, Berkeley.
