The crown structure of P4 and of the lower molars is close to that of Palaeothentoides and Macroscelides (Fig. 5). The lingual re- entrant between trigonid and talonid is less open than in these forms, and this narrowing was probably brought about by a swelling on the entoconid crest similar to but larger than that present in Palaeothentoides. Macroscelides has fossettids in the trigonids and talonids of unworn molars and these are closely com- parable, although much shallower than those occurring in Protypo- 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.
