Genal spine base transversely opposite lateral margin of L3 or S3; orientation of distal portion of posterior cephalic margin ranging from 4° inwards to 7° outwards relative to an exsagittal line when traced toward base of genal spine. Distance (tr.) between genal spine bases approximately 162% (range 140% to 174%) of glabellar length (sag.), increasing slightly through phase 5 of cephalic development. Angle between inner margin of proximal portion of genal spine and distal portion of posterior cephalic margin approximately 45° (range 42° to 49°). Width of anterior cephalic border (measured anterior to ocular lobes) 104% to 156% of length (exsag.) of LO. Ocular lobes divergent from exsagittal axis by approximately 15° (range 11° to 22°); posterior tip of ocular lobe transversely opposite lateral margin of L1 or distal tip of S1.
