BiPARENsis Greeii, 1956 Figure 1 Material: Nos. 17887, incomplete left lower jaw having Ml, M2-M3 (broken), alveoli of P4; 17888, incomplete left lower jaw having Mo, alveoli of P4, Mj, M3 ; 17889, left M2 (broken). In size (Table 1) and in most general characteristics these specimens resemble the type and only previously reported speci- men of Domninoides riparejisis, No. 53170, from the Clarendonian Wolf Creek faunule of South Dakota (Green, 1956, pp. 152-154). Compared to teeth in the type specimen, No. 17889 is less worn, No. 17887 is slightly more worn, and No. 17888 is much more w^ Fig. 1. Domninoides cf. view of left lower jaw, No. 17887, X 9. The most distinct difference from the type specimen is exhibited by No. 17887 (Fig. 1), which has on Mj a small but dis- tinct anterior cingulum that connects to the anterolingual cuspule. The anterior wall of M^ in the type is smoothly convex, lacking a cingulum. Another difference appears on M3 in No. 17887, which has an anterior cingulum that is more reduced buceally than in No. 53170. Also, in the type specimen the metastylid of Mj is larger than that of Mo, whereas in No. 17887 the metastylid of Mo is prominent and a distinct metastylid is absent on 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.
