20. TESTUDO. UB 7 
This species is based on a shell, which much resembles 7’. poly- 
phemus, but differs in the absence of a nuchal shield. It was 
afterwards referred by Gray to the synonymy of 7. polyphenws, 
of which it is perhaps only an anomalous specimen.

Shell very thick, elongate, not more than half as deep as long; 
carapace with straight upper profile, declivous in front and behind,

or but feebly notched; no nuchal shield ; supracaudal undivided, 
curved inwards; dorsal shields more or less strongly grooved con- 
centrically, rarely smooth; vertebral shields much broader than 
long, at least as broad as costals. Plastron large; front lobe not 
produced, truncate, bent upwards, not or but slightly extending 
beyond the carapace; hind lobe broadly notched posteriorly. Head 
moderate ; a large prefrontal and a large frontal, undivided, or one 
or both divided into two by a median suture; beak feebly hooked ; 
edge of jaws denticulated; alveolar surface of upper jaw with a 
strong, tubercular, median ridge. Fore limb anteriorly with large, 
unequal-sized, roundish, juxtaposed or subimbricate scales, one of 
which, on the inner side near the elbow, is usually much enlarged ; 
no conical tubercles on the back of the thighs. Carapace dark
