In form the younger individuals differ from the adults in being more rounded in front, the angles at the third peripherals not having vet been developt. The peripherals of the bridge region are not so high relatively as in the adults. The plastron of No. 5871 (text-fig. 562) has a total length of 253 mm. The anterior lobe is 67 mm. long and 142 mm. wide at the base. The lip is 62 mm. wide at the base and is slightly notcht in front. The upper surface is like that of the larger specimens. The bridges are 125 mm. wide. The posterior lobe of the plastron is 60 mm. long and 130 mm. wide at the base. It is broadly notcht behind. A still smaller individual found by Dr. Loomis is numbered 5873. It furnisht a shell only slightly damaged and not at all crusht, so that in it we have the form of the young. The shell is high and tumid. The peripherals above the bridge and the distal halves of the costals are ornamented with longitudinal grooves and ridges, which mark the growth of the horny scutes. This, like the other younger individuals, has a low boss on the first neural 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.
