Paired interorbital ridges prominent, separated by a channel more than twice width of 1 ridge, and ending at a ridge extending medially from postocular spine along incurved edge of moderately deep occipital pit. An oblique ridge lateral to each interorbital ridge from above middle of orbit, converging posteriorly with interorbital ridge. Tympanic spines about as long as postocular spines, close behind but separated from ridge extending medially from postocular spines. Median interorbital ridge prominent, reaching well into anterior interorbital space. First and 2nd suborbital spines oblique, sharply ridged, and with supplemental ridges. (Ref. 42181).
