There was evidently no thoracic excavation in the hinder face of the lip. The posterior lobe (fig. 628) was broadly notcht behind, the notch having a width of about 90 mm. and a depth of 35 mm. The terminal lobules are directed outward and upward, ear- like, somewhat as they are in Gopherus polyphemus, but not so narrow as they are in the latter. From the midline behind, the border is acute around the lobules and as far forward as about 35 mm. behind the hvpoxiphiplastral suture. Here it rather suddenly becomes broadly rounded as shown by the cross-section (fig. 628a). At the suture mentioned the thickness of the bone is 30 mm. The wall thus formed continues backward, descending somewhat, and meets the 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 Carnegie Institution of Washington.
