lobe, and connected with the carapace by a distinct bridge, the width 
of which is contained twice-and-a-half in the length of the plastron ; 
axillary and inguinal shields large, the suture between the pectoral shield 
and the marginals longer than that between the abdominal and the marginals, 
the suture between the pectoral shields as long as or a little shorter than 
that between the abdominals, the suture between the humeral shields 
shorter than that between the gulars, and that between the anals shorter than 
that between the femorals. Hook of the upper jaw bicuspid. Digits 
extensively webbed, claws long, curved, sharp. Front part of the jaw with 
broad, band-like transverse shields. Carapace dark brown, spotted with black 
in the young, plastron and lower surface of marginal shields yellowish, with 
symmetrical dark-brown markings in the young. Head and upper surface of 
the neck dark-brown ; a yellowish streak on each side of the head, from the 
upper surface of the snout to the neck, passing above the eye and the 
tympanum, another, higher up, and parallel with the lower, on the temple, on 
the neck, lower jaw and edge of upper jaw, yellowish. 
Of the two specimens, one {a) is newly born, the other {h) considerably 
older. 
{a) Length of shell, 6o mm. ; width, 55 mm. ; depth, 28 mm. Shields 
rugose ; an additional shield intercalated between the fourth and fifth verte- 
brals, and another between the fourth costal and the fifth vertebral. Vertebral 
keel and edge of marginals yellow ; roundish black spots irregularly disposed 
on the vertebral and costal shields ; marginal shields blackish above, speckled 
with lighter in their proximal third. Plastron with a complicated dark pattern 
with rounded outlines, between which are dark vermiculations; similar markings 
cover the bridge and the greater part of the lower surface of the marginals. 
{b^ Length of shell, 145 mm. ; width, 1 17 mm. ; depth, 67 mm. Shields 
with concentric grooves and radiating ridges around the rugose portion. 
Traces of the symmetrical dark markings of the younger specimen can be 
observed on the plastron. 
B. Description of the Adult Male. 
Shell three times as long as deep, once and two-thirds as long as broad ; 
its posterior border much less strongly serrated than in the young ; shields 
nearly smooth, with the vertebral keel merely indicated on the fourth and 
fifth vertebral shields ; second and third vertebral shields as long as broad, 
about two-thirds the width of the corresponding costals ; plastron deeply 
concave, the relative proportions of the shields as in the young. Upper 
jaw with two very strong median cusps, and a very distinct denticulation
