Carapace much depressed, oval, broadest behind, grooved along 
the vertebral region in the adult ; dorsal shields with radiating 
strie in the young, with vermicular rugosities in the adult ; nuchal 
shield large, usually considerably longer than broad ; first vertebral 
shield very large, fourth smallest. Plastron very large, its width 
(without the bridge) about half the length of the carapace, feebly 
angulated laterally ; front lobe 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 symphysis much less than 
half the diameter of the orbit. Neck and sides of head tubercular. 
Upper surface of fore hmb and lower surface of hind limb near the 
heel with large transverse lamellie, 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. longicollis. 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 intergular, which is nearly three times as long
