Schaeffer & Dunkle (1950 : 21) have shown the variation in the circumorbitals and suborbitals that can take place at the specific level within the genus Pholidophorus and this only adds further weight to the previous arguments. Further if the opisthotic in the neurocranium of the Amioidea is homologous with the autopterotic of the Pholidophoroidea, which is what I suspect, then a common.
