The teeth of an associated series, no. 23194 (fig. 133), are somewhat more worn, but generally similar to those of the former specimen, no. 23195. The small molar tooth of no. 23194 is of considerable interest in showing the reduction in size of the posterior portion of the series in this type. The small jaw fragment containing Mj and Mg (fig. 139) is important in showing the relatively small size of M;? of the worn 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.
