A series of two or three inframarginals separates the marginals from the abdo- minal, the transverse diameter of which equals at least twice the Fig. Shell of Chclydra serpentina. longitudinal. Snout short and pointed; interorbital space narrow. Skin very warty; a pair of very small barbels on the chin. Tail nearly as long as, or longer than, the carapace in the young, two thirds or three fourths that length in the halfgrown and adult; a strong crest of large compressed tubercles along its upper surface ; a series of large divided scutes along its lower surface. * From what is known to be the case in Staurofypiig, we may conclude that the specimens with broader bridge are 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 British Museum (Natural History).
