The sulci are narrow and sharply imprest. The nuchal scute is 40 mm. long and only Q mm. wide. < )n the lower side of the hone this scute has a posterior width ot 25 mm. The sulcus between the first and second marginals is 62 mm. long. The anterior width of the first vertebral has been 58 mm.

The anterior lip projects abruptly from the general outline of the anterior lobe for a distance of 35 mm. The anterior border of the lip is truncate, with the angle between it and the lateral border dipt off. The whole free edge of the epiplastron is acute, except near the midline, where it is slightly rounded. From the free edge of the lip the bone thickens. Testudo lipoma S24.
