Carapace much depressed, oval, broadest behind, grooved along 

 the vertebral region in the adult ; dorsal shieUls with radiating 

 strio) in the young, with vermicular rugosities in the adult ; nuchal 

 shield large, asuiiUy considerably longer tlian broad ; first vertebral 

 shield very large, fourth smallest. I'lastron very large, its width 

 (without the bridge) about half the length of the carapace, feebly 

 angulated laterally ; front lol)o nearly as wide as the carapace ante- 

 riorly, usually a little wider than the hind lobe, which is angularly 

 notched posteriorly; the longest plastral shield is the intergular, 

 -which is more than twice as long as the suture between the pectorals ; 

 suture between the anals as long as, or longer than, that between the 

 femorals. Head small ; snout short, obtuse ; interorbital space 

 narrow ; width of the lower jaw at the sym])hysis much less than 

 half the diameter of the orbit. Keck and sides of head tul)ercular. 

 Upper surface of fore limb and lower surface of hind limb near the 

 heel with large transverse lamclke, four or five in number on the 

 arm ; digits very broadly webbed. Dark brown above ; plastron 

 and lower surface of marginals yellow, with broad black lines along

 Carapace as in C. hnf/icoUis. Plastron intermediate in size between 

 that of the latter and that of C. expansa ; front lobe a little wider 

 than hind lobe and considerably shorter and narrower than the 

 corresponding half of the carapace ; the width of the plastron with- 

 out the bridge is a little more than half its length ; the longest 

 plastral shield is the intergnlar, which is nearly three times as long
