I he nares are .spacious, of somewhat jrreater heioht than breadth. I he external pterygoid plates are ev('rted; the pterygoid fos.sa is some- times deep (as. for instance, in No. 1T2102); sometimes very shallow (as in the case of No. U2195). The glenoids are broad and shallow, and are liounded e^xternally by the larofc zA’g’omatic tuberosity, posteriori}' by a well devel- oped ])ost-glenoid process, and me.sially by a pronounced tuberosity, formed by that part of tho temporal which lies next to the petrous lione. This elevation, but feebly rep- resented in human crania, seems to take in part the place of the .spinous process, which in the orangs is nearly or wholly absent. The eminen- tia articularis is very low. The floor of the auditory meati shows no dehiscence. The surface of the basilar proce.ss is, viewing the ba.se of the skull from above, generally on a lower level than the more elevated parts of the petrous portions of the temporal; and these portions extend forward well upon the body of the sphenoid, leaving only a small side- slit for the middle lacerated foramen. 'I'hese two features, to which the writer briefly drew attention before, constitute a very good index of the relative developmeiit of the brain and skull. In an intellectual white man the petrous portions, looked at from above, are decid('dly sunken below the level of the neighboring parts, which ofl'ered le.ss Fig. 3.—The right molar of fejiale orang (Cal.
