Several species of peccaries have been described from the Loup Fork beds. The Clifford collection contains two jaw fragments, apparently of different species. One of these differs from existing species in the fact that the last lower premolar is of much simpler construction than the Figure 6. — Fragment of mandible of molars and more perfect specimens would Peccarv X • probably show that this represents a dis- tinct genus; but it would be premature to propose a name for it in the absence of more complete material. GELOCID^J. BLASTOMERYX, Cope. This genus of true ruminants is abundantly represented in the collection. The type species, B. gemmifer, Cope, is from the Loup Fork, and differs from the closely allied Cosoryx chiefly in the brachyodont dentition. The later described species from the John Day formation not improbably belong to Pa- Iwomeryx, from which Blastomeryx is distinguished by the absence of the char- acteristic fold on the lower molars, and the greater narrowness and compression of the molar 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 Harvard University.
