a Complete: supraorbital and infraorbital branches of the stapedial artery form major blood supply to the orbitofacial region; sphenofrontal and stapedial foramina present; vascular grooves cross both the inner surface of the squamosal and alisphenoid bones and the posterolateral corner of the parapterygoid fossa; posterior opening to alisphenoid canal large.
b Derived: supraorbital and infraorbital branches absent, distal orbitofacial circulation arising from secondary anastomosis to the internal carotid; sphenofrontal foramen absent, stapedial foramen absent or minute; no vascular grooves found on the inner surface of the squamosal and alisphenoid bones or on the posterolateral corner of the parapterygoid fossa; posterior opening to alisphenoid canal irregularly formed or occluded; secondary osseous groove internally crosses the roof of the parapterygoid fossa.
c Based on the type as restricted by Musser and Patton (1989).
