that between humerals and pectorals a straight transverse line ;

Carapace much depressed, feebly keeled. Nuchal shield small, 

 trapezoidal, broadest posteriorly ; hrst vertebral wifh sinuous lateral 

 borders, usually a little narrower in front than behind ; second 

 vertebral shortest, bi'oader than long, usually with straight or 

 slightly convex posterior border ; third vertebral considerably 

 longer than broad, subquadrangular, posterior border straight or 

 sliglitly convex ; fourth vertebral longest, tapering anterioidy and 

 forming a narrow suture with the third ; fifth vertebral much 

 broader than the others. Plastron feebly angulated laterally, 

 large ; front lobe rounded, hind lobe angularly notched and as long 

 as or a little shorter than the width of the bridge ; the longest 

 median suture is that between the abdominals, which about equals 

 the length of the front lobe ; gulars usually shorter than the 

 suture between the humerals, their suture with the latter shields 

 forming a right angle ; inguinal large, axillary smaller. Head 

 moderate ; snout short, obtuse, feebly ])romiuent ; jaws with 

 denticulated edge, upper not notched mesially ; alveolar surface of 

 upper jaw broad, the median ridge nearer the inner than the outer 

 border ; bony choante between the orbits ; the width of the lower 

 jaw at the symphj'sis is less than the diameter of the orbit. Pore 

 limbs with large transverse scales. Pale olive-brown above ; dorsal 

 keel usually blackish ; plastral shields and lower surface of mar- 

 ginals dark brown, bordered with yellow.

Carapace elevated, tectiform, the keel ending in an elevated 

 pointed nodosity on the third vertebral shield, forming a strong 

 ridge on the last two vertebrals ; posterior margin very strongly 

 serrated ; 26 marginal shields, instead of 24 as in all other species 

 of the genus ; first vertebral shield much broader in front than 

 behind in the half-grown specimens, equally broad in front and
