Amboina. From the Levden Mu- 



Ciiora Amboinensis is called " Baninr/ " by the Malays 

 of the Peninsula ; it is numerous in the ponds, rivulets and 

 paddy-fields in the valley of Pinang. The dorsal keels 

 become obsolete with age, and the margms of the shell, 

 particularly the hinder part, become revolute. — Cantor. 



Schlegel regards Eimjs castcmea, E. subitiger, Terrapene 

 bicolor, Stei-notherus trifasciatus and St. Leachianus as 

 varieties of this species. 



Leconte most erroneously confounds this with Cistudo 

 Carolina. 



2. Cuora trifasciata. The Three-streaked Coura. 



Shell subovate, hemispherical, solid, keeled, dull yellow, 

 red and black varied, with three blackish dorsal streaks. 

 Sternum bifid behind. Head yellow, with two horizontal 

 black streaks on the side of the head and neck, upper wider, 

 with a triangular paler spot in front and two larger oval 

 ones behind.

13. CYCLEMYS. 



Head ovate, covered, with a thin skin ; forehead rather 

 convex. Eyes subsuperior. Legs strong, covered in front 

 with thin, broad, band-like, transverse shields. Toes strong, 

 covered with small scales above, webbed to the claws ; claws 

 5 • 4, short, curved, acute. Tail moderate. Shell convex, 

 solid, edge-toothed behind. Sternum rounded in front, 

 truncated behind, narrower than the cavity, not covering 

 the legs when contracted, with a distinct process on each 

 side to form the symphysis. The cross suture between the 

 anterior and posterior lobe in the middle of the long sterno- 

 costal suture, so that both lobes are equally attached to the 

 thorax. Asiatic. 



This genus has the same shield-like and well-webbed toes 

 as Einys and Cuora, but differs from the latter in the ster- 

 nal lobes being narrower than the opening of the thorax, so 

 that, as in Emys, it does not cover the legs when they are 

 contracted. This similarity has induced naturalists to place 

 the species in the genus Emys, overlooking the fact of the 

 lobes being mobile.
