Kiimmel. 1 hese bones hail lain tor mam' years in the basement of the capitol and all knowledge t their origin had been lost. Without doubt, the) bad been obtained from the I'pper Cretaceous gteensand ot New Jersey. Of this individual there are large portions preserved, but there are so many parts missing that the shell can be only partially restored. ()t the carapace there were secured a considerable part of the anterior and posterior free borders and some fragments of costals. Of the plastron some important parts can be identified. The individual is estimated to have had a carapace about 700 mm. long. Most of the nuchal bone is present (fig. 125), but, on account of the absence of a section of it, its exact width can not be determined. It was not far from 120 mm. The hinder portion is missing. The thickness near the midline in front is 13 mm.; backward the bone thins to 6 mm., while at its outer ends it is 18 mm. thick. The whole free edge is obtuse. The first peripheral (fig. 125) has a length along the free border of 83 mm., a fore-and-aft extent of h^ mm. The thickness at the suture with the second peripheral is 24 mm.; at the suture with the first costal, 8 mm. The second peripheral (fig. 125) extends 90 mm. along the free border; 70mm. fore and aft; and is 20 mm. thick where it joined the third. Its hinder border somewhat overlapt the first 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.
