Nuchal plate broad, much broader behind than in front, with truncated anterior margin. First vertebral much broader than long, concave, with parallel lateral margins ; second, third, and fourth very much broader than long ; posterior margin of the fourth only half as long as anterior ; fifth vertebral but slightly broader than long, and rather convex behind. Caudal divided. Costals deeply impressed in their areolar portion, more so than the veitebrals. Gulars subrhomboid, but rather irregular, Geoemyda impressa (side view). joined at an obtuse angle in front and behind. Postgulars enlarged at the expense of the pectorals, which are very narrow, the length of their median suture being only one fourth of the suture between the postgulars. Abdominals very large, as long as the preceding three pairs of plates together. Praeauals broader than long. Anais similar in shape to the gulars, but larger, and joined at an acute angle posteriorly. The prominent colour is yellow in the areolar portion, but each of the vertebral, costal, and sternal plates is ornamented towards the margin with broad black radiating bands, and the anterior half or third of each of the marginals is black. |
