The second and third vertebral scutes are urn-shaped, expanded in front, and narrowed behind. The first vertebral is the broadest. The dimensions of vertebral and marginal scutes are given in the second table 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.
