 Cyclemys, Bell. 



Thorax depressed, keeled, separated from the sternum by a 

 iJOfamentous suture. Sternum flat in both sexes, divided into 

 two parts by a transverse mobile pseudo-hinge, formed by the 

 permanent non-anchylosis of the pectoro-abdominal suture, 

 simulative of the cartilaginous joint of CuoiiA, and indicated in 

 adults by a carious fossa across the external plates. In young- 

 specimens, this hinge remains undeveloped. Herbivorous. Food 

 consists of fruits of Ficus, &c. Eggs large, cylindrical, four in 

 number.

Nuchal plate small. Shell in young orbicular, expanded, 

 strongly keeled, strongly toothed posteriorly. Colour pale olive, 

 radiately brown streaked from a large superoposterior granular, 

 umbo, or areola, which in the marginal plates is postero-marginal. 



Pupil round, black, iris, greyish yellow, brown spotted. Skin, 

 of neck yellow, lined with brown, of body yellow. Specimens of 

 this size 3-| inches, have no trace of the transverse sternal hinge. 



Half grown ones of five inches have the sternum deep brown 

 or blackish, yellow rayed, and the yellow iris much encroached 

 on by brown spots. Sternal hinge distinct. Adults of eight inches 

 are uniform brown with all markings effaced ; keel obsolete. 

 Iris wholly umber brown, and the sternal hinge now marked 

 exteriorly by a carious line across the outer horny plates, the 

 result of the motion of the unanchylosed hinge beneath them, 

 vide Glinther's fig. of 0. Oldhami. Fingers slightly, toes broadly 

 webbed. 



Grows to eight inches, or rather more. 



Inhabits Pegu, Tenasserim, and North- Western India, Camboja, 



&c.
