Mohave Beds, Mohave Desert, California. Tig. 8a, superior view; fig. 86, lateral view. P4 and P3 both possess a posterior cusp and a posterior basal tubercle. P4 shows a small anterior basal tubercle. The anterior side of P3 is not preserved. Several specimens of mandibles slightly larger than no. 19-402 represent a Tephrocyon species from the Mohave Beds very near T. temerarius. It is possible that they belong to another species, but age and sex are presumably competent to account for the differences. Tephrocyon kelloggi Merriam, J. C. Tephrocyon kelloggi Merriam. Univ. Calif. Pub!., Bull. Dept. Geol., vol. 6, p. 235, 1911. To this species there have been referred several jaws and detached teeth from the middle Miocene Virgin Valley Beds of northern Nevada. A single tooth from the early Pliocene of.
