The heads of these two animals have a triangular and acute shape, with pileus lateral margins straight convergent to the snout (subparallel). In the Hierro Giant lizard the pileus shape is more oval, with curved sides. The median supraocular plates (2—3) are much broader and, thus, a little protruding, giving the animal's eyes a slight "frog"like profile. Head of simonyi is flat, as in stehlini. See figure 26 A.

The configuration of the snout in the Hierro Giant lizard differs, too (fig. 26 B). Besides being more rounded, what first attracts the attention is the size of the nostril. It is very conspicuous, completely circular and much larger, with its diameter as long as the distance from its border to the mouth Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Zoologisches Forschungsinstitut und Museum Alexander Koenig.
