Attempted reconstruction of the skull of Nyanzachoerus plicatus. X %• itself. These canines undoubtedly belong to the same species and are cited as para- types. The skull—if it can be dignified by such a designation—consists mainly of the snout from a point 7 cm behind the supraorbital foramina to the front of the canine fossae. The right side is very badly damaged, but the left side shows the lacrimal area and maxillary part of the beginning of the zygomatic arch (PI. 13). A partial and very tentative restoration, based on all the material available and especially on the holotype and the third paratype, is given in 1-^igure 7. The lacrimal and supra-orbital foramina and a very small part of the margin of the orbit are preserved on the left side. The arrangement of the foramina is phaco- choeroid; the lacrimal foramina are situ- ated very close to the margin of the orbit and the supra-orbital foramen is virtually at the same level. In the supra-orbital foramen lies fiuther forward, distinctly anterior to the lacrimal foramina, and the latter lie slightly further in front of the orbit, so that the distance between the infra-orbital and supra-orbital foramina is much less than in PliococJioenis. This distance is no more than 10 cm in a big skull of IlylocJiociiis as against 15 cm for Pliacoclioeriis; in the fossil skull, this dis- tance is almost 20 cm, indicating that the cranium has the same sort of backward elevation as does that of In Fhacochoerus this is achieved by elonga- tion at the level of the lacrimal and jugal. In the fossil, the lower margin of the lacrimal is not complete, but the preserved portion of the suture with the jugal mea- sures just o\ er 5 cm in front of the orbit. In a large Htjlochoerus the suture is no longer than cm, so it would appear that in the foss
