Of the seventh there is present a fragment 46 mm. long and 31 mm. wide at the sulcus. The rib-heads of the fifth and sixth costals have a diameter of about 6 mm. No trace of the articulation for the inguinal buttress appears on the parts preserved of the fifth and sixth costals. It is evident, therefore, that this buttress did not ascend to as high a point as did the axillary. From the form of the sutural border of the supposed inguinal buttress it is believed that the latter was articulated to the fifth and sixth at their junction. Of the plastron (fig. 95) there are present a fragment of the left epiplastron, a large part nt the right hyoplastron, the left hypoplastron, and a portion of the free border of the right xiphiplastron. These are represented in the diagrammatic figure. That this turtle possest a mesoplastron is evident; otherwise, the bridges would have been only about 100 mm. wide, about one-half as wide as the costals spanned by the two buttresses of one side. No part of the mesoplastrals appears to be included among the bones present. Their antero-posterior width is only 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.
