Fig. 9 in A Systematic Review Of Sulawesi Bunomys (Muridae, Murinae) With The Description Of Two New Species

Fig. 9. Lateral view of the same specimen of Bunomys chrysocomus depicted in figure 8 showing details of the alisphenoid region. No strut of alisphenoid bone conceals the alisphenoid canal (ac) so the anterior opening of the alisphenoid canal (aac) is exposed, and the foramen ovale (fo) is confluent with the masticatory-buccinator foramen (mbf), the configuration common to all species of Bunomys. Also shown is the narrow periotic (pt), the short bony eustachian tube (et), the anterior alar fissure (af), squamosal (sq) and alisphenoid (al).
