Section across shell at the inguinal buttresses. Shows the sisth peripheral (per. 6), the fifth costal plate (c. p. 5), and the right and left inguinal buttresses (r. ing., I. ing). It will be observed that the second marginal is unusually high. This is true in both No. 6085 and No. 6089. As shown by both these specimens, the costo-marginal sulci run near the costo-peripheral sutures; in No. 6085. a

The plastron (fig. 416) has a total length of 345 mm. The anterior lobe is 95 mm. long and 133 mm. wide at the base, the length thus being 71 per cent, of the width. The entoplastron is 50 mm. long and 53 mm. wide-. Immediately in front of the axillary notch the lobe narrows a 21.
