346 DR. A. GUNTHER ON A NEW TORTOISE. [Apr. 4, 
incisions is equal to that between the hinder, and a little more than 
one half of its length. 
Areolee distinct. 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 vertebrals. 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. Praeanals broader than long. Anals 
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.
