in ponds about the rice-fields, and has watched them basking, several 

 at a time, on the tops of large stones in such ponds. 



iii. The hind feet fattened, fringed; toes webbed and with band- 

 like shields above. 

 4. CUORA. 



The thorax rather convex, more or less three-ridged. The sternum 

 flat ; lobes subequal, both enclosed in the symphysis. Head flat at 

 top ; eyes lateral. The front of the fore legs with large scales. The 

 toes all banded above, webbed. The claws conical. The hind feet 

 depressed ; the hinder edge fringed and angularly produced, Asiatic. 



* The head large, flat, with two yellow streaks on each side ; back 

 one-coloured ; toes broadly webbed. Cuora.

 Hab. Amboina; Gilolo ( ^«//ace) ; ^OTn&o {Wallace). 



** Head smaller, oblong, with two dark streaks on each side ; back 

 three-banded ; toes narrowly webbed. Pyxiclemmys.

 Hab. China. 



5. LUTREMYS. 



Thorax depressed. Sternum flat ; lobes subequal, both enclosed 

 in the symphysis. Head ovate ; eyes superior. The legs with large 

 scales in front. The feet depressed ; toes webbed, banded above ; 

 the hind feet fringed and angularly produced behind. Claws elon- 

 gate, acute. 



LuTREMYS EUROP^A, Gray, Cat. Shield Reptiles B.M. p. 40. 



Hab. Europe. 



Very variable in colour. 



iv. Toes webbed; they and legs covered with very small scales ; 

 front legs only with thin band-like plates in front ; the lobes 

 of the sternum narrow. 



6. NOTOCHELYS. 



Back convex, flattened above. The sternum flexuous ; lobes rather 

 narrow, truncated in front and behind. The legs and toes covered 

 with minute scales ; the front legs having a series of broad, thin, 

 band-like shields in front. Toes webbed. Claws acute. 



This genus is like a true Emys in most of its characters ; but the 

 sternum is scarcely raised above the underside of the margin, and 

 is united to the thorax by a cartilaginous symphysis ; the lobes are 

 separated by a straight depressed suture, but scarcely moveable. It 

 differs from all the other CistudincB in the legs and toes being 

 covered with minute lanceolate scales as in Batagur, with only a few 

 very narrow shields near the claws.
