The lateral border runs nearly straight to a point some distance in front of the hyo- epiplastral suture, then rounds rapidly to the lip. The lip is 53 mm. wide. It projects little and is furnisht with a right and a left lateral tooth and 2 closely placed median teeth. Between the lateral tooth and the midline the upper surface of this lip is considerably excavated. The thickening of the epiplastrals on the upper surface (fig. 444) extends backward 30 mm. The greatest thickness of these bones is 12 mm. The median space between these thickenings on the upper surface is somewhat excavated. The free borders of the lobe are acute nearly to the lip. The beveled surface on the upper side of the epiplastrals has a width of only 12 mm. at the hyoepiplastral suture. The entoplastron is 50 mm. long and 60 mm. wide. The bridge has a width of 137 mm. The hinder lobe is 98 mm. long and 143 mm. wide at the base. The length of the lobe equals therefore about 69 per cent, of the width. There is a rather broad notch at the rear of the lobe. Its width is about 12 mm.
